iOS地图 (原生高德地图)
本篇博客为我的第一篇博客,如果哪里解释的不全面还希望各位及时指正.
主要内容:
1.使用Apple自带的高德地图
2.通过地名定位转换出坐标,通过坐标定位出详细信息
3.定位,显示地图,地图添加大头针,自定义大头针
1.使用Apple自带的高德地图
1)需要引入两个头文件:
(1). CoreLocation/CoreLocation.h用于定位
(2). MapKit/MapKit.h用于显示地图
#import <CoreLocation/CoreLocation.h>
#import <MapKit/MapKit.h>
2)定义一个高德地图属性
@interface MapOfAppleViewController ()
@property (nonatomic, strong) CLGeocoder *geocoder;
@end
3)viewDidLoad方法
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.view.backgroundColor = [UIColor whiteColor];
/**
初始化高德地图
*/
self.geocoder = [[CLGeocoder alloc]init];
/* 下面会详述该方法 */
//[self location];
[self listPlacemark];
}
4)location方法(此方法只有定位,没有重定位)
- (void)location
{
/**
* 根据"XXX"进行地理编码
*
* @param placemarks block
* @param error nil
*
* @return void
*/
[self.geocoder geocodeAddressString:@"沙河口区" completionHandler:^(NSArray *placemarks, NSError *error) {
/**
* 获取第一个地标
*/
CLPlacemark *clPlacemark = [placemarks firstObject];
/**
定位地标转化为地图的地标
*/
MKPlacemark *mkPlacemark = [[MKPlacemark alloc]initWithPlacemark:clPlacemark];
NSDictionary *options = @{MKLaunchOptionsMapTypeKey:@(MKMapTypeStandard)};
MKMapItem *mapItem = [[MKMapItem alloc]initWithPlacemark:mkPlacemark];
[mapItem openInMapsWithLaunchOptions:options];
}];
}
5)listPlacemark方法(此方法可以同时定位两个位置)
- (void)listPlacemark
{
/**
* 根据"XXX"进行地理编码
*
* @param placemarks block
* @param error nil
*
* @return void
*/
[self.geocoder geocodeAddressString:@"北京市" completionHandler:^(NSArray *placemarks, NSError *error) {
/**
* 获取第一个地标
*/
CLPlacemark *clPlacemark1 = [placemarks firstObject];
/**
定位地标转化为地图的地标
*/
MKPlacemark *mkPlacemark1 = [[MKPlacemark alloc]initWithPlacemark:clPlacemark1];
/**
* 注意地理编码一次只能定位到一个位置,不能同时定位,所在放到第一个位置定位完成回调函数中再次定位
*
* @param placemarks block
* @param error nil
*
* @return void
*/
[self.geocoder geocodeAddressString:@"大连市沙河口区" completionHandler:^(NSArray *placemarks, NSError *error) {
CLPlacemark *clPlacemark2 = [placemarks firstObject];
MKPlacemark *mkPlacemark2 = [[MKPlacemark alloc]initWithPlacemark:clPlacemark2];
NSDictionary *options = @{MKLaunchOptionsMapTypeKey:@(MKMapTypeStandard)};
MKMapItem *mapItem1 = [[MKMapItem alloc]initWithPlacemark:mkPlacemark1];
MKMapItem *mapItem2 = [[MKMapItem alloc]initWithPlacemark:mkPlacemark2];
[MKMapItem openMapsWithItems:@[mapItem1, mapItem2] launchOptions:options];
}];
}];
}
运行结果(效果图):
2.通过地名定位转换出坐标,通过坐标定位出详细信息
1)需要导入CoreLocation.framework框架
2)在工程中引入头文件
/**
* 导入CoreLocation.framework框架, 用于定位使用
*
* @param void
*
* @return nil
*/
#import <CoreLocation/CoreLocation.h>
3)签协议,使用高德地图
@interface TwoLocationStylesViewController ()<CLLocationManagerDelegate>
/**
* 签好协议,定义高德地图属性
*/
@property (nonatomic, strong)CLGeocoder *geocoder;
@end
4)以下是实现部分ViewDidLoad
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.view.backgroundColor = [UIColor whiteColor];
/**
初始化高德地图属性
*/
self.geocoder = [[CLGeocoder alloc]init];
#pragma mark ** 地名->坐标
[self getCoordinateByAddress:@"大连"];
#pragma mark ** 坐标->地名
//[self getAddressByLatitude:39.54 longitude:116.28];/* 北京坐标 */
}
5)根据地名确定地理坐标(地名->坐标)
#pragma mark - 根据地名确定地理坐标(地名->坐标)
- (void)getCoordinateByAddress:(NSString *)address
{
[self.geocoder geocodeAddressString:address completionHandler:^(NSArray *placemarks, NSError *error) {
/**
* 地理编码,取得第一个地标,一个地名可能搜出多个地址(placemark为数组)
*/
CLPlacemark *placemark = [placemarks firstObject];
/**
* 位置
*/
CLLocation *location = placemark.location;
/**
* 区域
*/
CLRegion *region = placemark.region;
/**
* 详细的地址信息通过字典存储
*/
NSDictionary *addressDic = placemark.addressDictionary;
/**
* 详细信息字典包含以下信息
*
*/
// NSString *name = placemark.name;/* 地名 */
// NSString *thoroughfare = placemark.thoroughfare;/* 街道 */
// NSString *subThoroughfare = placemark.subThoroughfare;/* 街道相关信息,例如门牌等 */
// NSString *locality = placemark.locality;/* 城市 */
// NSString *subLocality = placemark.subLocality;/* 城市相关信息,例如标志性建筑 */
// NSString *administrativeArea = placemark.administrativeArea;/* 州 */
// NSString *subAdministrativeArea = placemark.subAdministrativeArea;/* 其他行政区域信息 */
// NSString *postalCode = placemark.postalCode;/* 邮编 */
// NSString *ISOcountryCode = placemark.ISOcountryCode;/* 国家编码 */
// NSString *country = placemark.country;/* 国家 */
// NSString *inlandWater = placemark.inlandWater;/* 水源,湖泊 */
// NSString *ocean = placemark.ocean;/* 海洋 */
// NSArray *areasOfInterest = placemark.areasOfInterest;/* 关联或者利益相关的地标 */
/**
* 以下是简短的输出
*/
NSLog(@"位置:%@", location);
NSLog(@"区域:%@", region);
NSLog(@"详细信息:%@", addressDic);
}];
}
6)根据坐标获取地名(坐标->地名)
- (void)getAddressByLatitude:(CLLocationDegrees)latitude longitude:(CLLocationDegrees)longitude
{
/**
反地理编码
*/
CLLocation *location = [[CLLocation alloc]initWithLatitude:latitude longitude:longitude];
[self.geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error) {
CLPlacemark *placemark = [placemarks firstObject];
NSLog(@"详细信息:%@", placemark.addressDictionary);
}];
}
运行结果:(控制台输出结果)
3.定位,显示地图,地图添加大头针,自定义大头针(结合之前的定位(地名->坐标)实现一次显示地图,并且定位,插入自定义的大头针,点击大头针显示具体的位置信息)
//------------------2017年2月7日补充如下-----------------
补充:很多人使用iOS原生的地图之后会发现,我们不能够随意的定义地图显示的比例尺,不同于百度、高德集成后的SDK,所以对于这个我们要进行延展,为此我们添加了一个类目,提供一个方法,用来设置地图的缩放比例。
// MKMapView+ZoomLevel.h
#import <MapKit/MapKit.h>
@interface MKMapView (ZoomLevel)
- (void)setCenterCoordinate:(CLLocationCoordinate2D)centerCoordinate
zoomLevel:(NSUInteger)zoomLevel
animated:(BOOL)animated;
@end
// MKMapView+ZoomLevel.m
#import "MKMapView+ZoomLevel.h"
#define MERCATOR_OFFSET 268435456
#define MERCATOR_RADIUS 85445659.44705395
@implementation MKMapView (ZoomLevel)
#pragma mark -
#pragma mark Map conversion methods
- (double)longitudeToPixelSpaceX:(double)longitude
{
return round(MERCATOR_OFFSET + MERCATOR_RADIUS * longitude * M_PI / 180.0);
}
- (double)latitudeToPixelSpaceY:(double)latitude
{
return round(MERCATOR_OFFSET - MERCATOR_RADIUS * logf((1 + sinf(latitude * M_PI / 180.0)) / (1 - sinf(latitude * M_PI / 180.0))) / 2.0);
}
- (double)pixelSpaceXToLongitude:(double)pixelX
{
return ((round(pixelX) - MERCATOR_OFFSET) / MERCATOR_RADIUS) * 180.0 / M_PI;
}
- (double)pixelSpaceYToLatitude:(double)pixelY
{
return (M_PI / 2.0 - 2.0 * atan(exp((round(pixelY) - MERCATOR_OFFSET) / MERCATOR_RADIUS))) * 180.0 / M_PI;
}
#pragma mark -
#pragma mark Helper methods
- (MKCoordinateSpan)coordinateSpanWithMapView:(MKMapView *)mapView
centerCoordinate:(CLLocationCoordinate2D)centerCoordinate
andZoomLevel:(NSUInteger)zoomLevel
{
// convert center coordiate to pixel space
double centerPixelX = [self longitudeToPixelSpaceX:centerCoordinate.longitude];
double centerPixelY = [self latitudeToPixelSpaceY:centerCoordinate.latitude];
// determine the scale value from the zoom level
NSInteger zoomExponent = 20 - zoomLevel;
double zoomScale = pow(2, zoomExponent);
// scale the map’s size in pixel space
CGSize mapSizeInPixels = mapView.bounds.size;
double scaledMapWidth = mapSizeInPixels.width * zoomScale;
double scaledMapHeight = mapSizeInPixels.height * zoomScale;
// figure out the position of the top-left pixel
double topLeftPixelX = centerPixelX - (scaledMapWidth / 2);
double topLeftPixelY = centerPixelY - (scaledMapHeight / 2);
// find delta between left and right longitudes
CLLocationDegrees minLng = [self pixelSpaceXToLongitude:topLeftPixelX];
CLLocationDegrees maxLng = [self pixelSpaceXToLongitude:topLeftPixelX + scaledMapWidth];
CLLocationDegrees longitudeDelta = maxLng - minLng;
// find delta between top and bottom latitudes
CLLocationDegrees minLat = [self pixelSpaceYToLatitude:topLeftPixelY];
CLLocationDegrees maxLat = [self pixelSpaceYToLatitude:topLeftPixelY + scaledMapHeight];
CLLocationDegrees latitudeDelta = -1 * (maxLat - minLat);
// create and return the lat/lng span
MKCoordinateSpan span = MKCoordinateSpanMake(latitudeDelta, longitudeDelta);
return span;
}
#pragma mark -
#pragma mark Public methods
- (void)setCenterCoordinate:(CLLocationCoordinate2D)centerCoordinate
zoomLevel:(NSUInteger)zoomLevel
animated:(BOOL)animated
{
// clamp large numbers to 28
zoomLevel = MIN(zoomLevel, 28);
// use the zoom level to compute the region
MKCoordinateSpan span = [self coordinateSpanWithMapView:self centerCoordinate:centerCoordinate andZoomLevel:zoomLevel];
MKCoordinateRegion region = MKCoordinateRegionMake(centerCoordinate, span);
// set the region like normal
[self setRegion:region animated:animated];
}
@end
使用时:
#import "MKMapView+ZoomLevel.h"
#define GEORGIA_TECH_LATITUDE 33.777328
#define GEORGIA_TECH_LONGITUDE -84.397348
#define ZOOM_LEVEL 14
CLLocationCoordinate2D centerCoord = { GEORGIA_TECH_LATITUDE, GEORGIA_TECH_LONGITUDE };
[map setCenterCoordinate:centerCoord zoomLevel:ZOOM_LEVEL animated:NO];
//------------------2017年2月7日补充如上-----------------
1)导入MapKit.framework与CoreLocation.framework框架
2)引入两个头文件
/**
* 这两个包必须导入
*
* @param void
*
* @return
*/
#import <CoreLocation/CoreLocation.h>
#import <MapKit/MapKit.h>
3).h文件定义一个属性接受传来的值(输入的地理位置)
@interface MapAndLocationViewController : UIViewController
/**
* 输入的名字
*/
@property (nonatomic, retain) NSString *place;
@end
4).m文件属性以及协议使用
/**
* 签个协议 MKMapViewDelegate
*/
@interface MapAndLocationViewController ()<MKMapViewDelegate,CLLocationManagerDelegate>
@property (nonatomic, retain)CLLocationManager *locationManager;
/**
* 位置
*/
@property (nonatomic, retain)CLLocation *location;
@property (nonatomic, retain)MKMapView *mapView;
/**
* 详细信息显示名字
*/
@property (nonatomic, retain)NSString *name;
/**
* 签好协议,定义高德地图属性
*/
@property (nonatomic, strong)CLGeocoder *geocoder;
@end
5)ViewDidLoad方法
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.view.backgroundColor = [UIColor whiteColor];
/**
初始化高德地图属性
*/
self.geocoder = [[CLGeocoder alloc]init];
#pragma mark ** 地名->坐标
[self getCoordinateByAddress:self.place];
}
6)根据地名确定地理坐标(地名->坐标)(上面已经给予详细解释)
- (void)getCoordinateByAddress:(NSString *)address
{
[self.geocoder geocodeAddressString:address completionHandler:^(NSArray *placemarks, NSError *error) {
/**
* 地理编码,取得第一个地标,一个地名可能搜出多个地址(placemark为数组)
*/
CLPlacemark *placemark = [placemarks firstObject];
/**
* 位置
*/
//CLLocation *location = placemark.location;
self.location = placemark.location;
/**
* 区域
*/
CLRegion *region = placemark.region;
/**
* 详细的地址信息通过字典存储
*/
NSDictionary *addressDic = placemark.addressDictionary;
/**
* 详细信息字典包含以下信息
*
*/
self.name = placemark.name;/* 地名 */
// NSString *thoroughfare = placemark.thoroughfare;/* 街道 */
// NSString *subThoroughfare = placemark.subThoroughfare;/* 街道相关信息,例如门牌等 */
// NSString *locality = placemark.locality;/* 城市 */
// NSString *subLocality = placemark.subLocality;/* 城市相关信息,例如标志性建筑 */
// NSString *administrativeArea = placemark.administrativeArea;/* 州 */
// NSString *subAdministrativeArea = placemark.subAdministrativeArea;/* 其他行政区域信息 */
// NSString *postalCode = placemark.postalCode;/* 邮编 */
// NSString *ISOcountryCode = placemark.ISOcountryCode;/* 国家编码 */
// NSString *country = placemark.country;/* 国家 */
// NSString *inlandWater = placemark.inlandWater;/* 水源,湖泊 */
// NSString *ocean = placemark.ocean;/* 海洋 */
// NSArray *areasOfInterest = placemark.areasOfInterest;/* 关联或者利益相关的地标 */
/**
* 以下是简短的输出
*/
NSLog(@"位置:%@", self.location);
NSLog(@"区域:%@", region);
NSLog(@"详细信息:%@", addressDic);
/* 添加地图 */
[self initMap];
}];
}
7)添加地图控件
- (void)initMap
{
/**
* 地图大小
*/
CGRect rect = [UIScreen mainScreen].bounds;
self.mapView = [[MKMapView alloc]initWithFrame:rect];
[self.view addSubview:self.mapView];
/**
* 签代理
*/
self.mapView.delegate = self;
/**
请求定位服务
*/
self.locationManager = [[CLLocationManager alloc]init];
if (![CLLocationManager locationServicesEnabled] || [CLLocationManager authorizationStatus] != kCLAuthorizationStatusAuthorizedWhenInUse) {
[self.locationManager requestWhenInUseAuthorization];
}
/**
* 用户位置追踪(标记用户当前位置,此时会调用定位服务)
*/
self.mapView.userTrackingMode = MKUserTrackingModeFollow;
/**
* 地图类型
*/
self.mapView.mapType = MKMapTypeStandard;
/* 添加大头针 */
[self addAnnotation];
}
8)添加大头针
- (void)addAnnotation
{
/* 坐标 */
CLLocationCoordinate2D location1 = self.location.coordinate;
KCAnnotation *annotation1 = [[KCAnnotation alloc]init];
//以下两行使用的是系统弹出的大头针会显示出来 具体信息根据需求提供
//annotation1.title = @"";
//annotation1.subtitle = @"";
annotation1.coordinate = location1;
annotation1.image = [UIImage imageNamed:@"icon_paopao_waterdrop_streetscape.png"];
annotation1.icon = [UIImage imageNamed:@"icon_mark1.png"];
annotation1.detail = self.name;
annotation1.rate = [UIImage imageNamed:@"icon_Movie_Star_rating.png"];
[self.mapView addAnnotation:annotation1];
/**
* 定位北京
*
* @param 39.87 北京经度
* @param 116.35 北京纬度
*
* @return
*/
CLLocationCoordinate2D location2=CLLocationCoordinate2DMake(39.87, 116.35);
KCAnnotation *annotation2=[[KCAnnotation alloc]init];
annotation2.coordinate=location2;
annotation2.image=[UIImage imageNamed:@"icon_pin_floating.png"];
annotation2.icon=[UIImage imageNamed:@"icon_mark1.png"];
annotation2.detail=@" 中国.北京 ";
annotation2.rate=[UIImage imageNamed:@"icon_Movie_Star_rating.png"];
[_mapView addAnnotation:annotation2];
}
9)地图控件代理方法,显示大头针的时候会调用该方法,MKAnnotationView返回值是自定义的大头针对象
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation
{
/**
* 地图控件代理方法
*
* @return 返回值是nil 返回的是系统默认的大头针 要使用自定义的大头针要加判断
*/
if ([annotation isKindOfClass:[KCAnnotation class]]) {
/* 定义一个缓冲池 */
static NSString *reuse = @"AnnotationKey";
MKAnnotationView *annotationView = [self.mapView dequeueReusableAnnotationViewWithIdentifier:reuse];
if (!annotationView) {
annotationView = [[MKAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:reuse];
annotationView.calloutOffset = CGPointMake(0, 1);
annotationView.leftCalloutAccessoryView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"icon_classify_cafe"]];
}
/* 重新修改大头针,从缓冲池中取出来的大头针可能还会放到原来的位置(进池之前的位置) */
annotationView.annotation = annotation;
annotationView.image = ((KCAnnotation *)annotation).image;/* 重设大头针图片 */
return annotationView;
}
else
if ([annotation isKindOfClass:[KCCalloutAnnotation class]]) {
/**
* 作为自定义的弹出大头针 没有任何交互功能(canShowCallout = false, 这是默认值),可以添加其他的视图(继承自UIView)
*
* @return
*/
KCCalloutAnnotationView *calloutView = [KCCalloutAnnotationView calloutViewWithMapView:mapView];
calloutView.annotation = annotation;
return calloutView;
}
else
{
return nil;
}
}
10)选中大头针触发的方法(弹出详情视图大头针)
- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view
{
KCAnnotation *annotation = view.annotation;
if ([view.annotation isKindOfClass:[KCAnnotation class]]) {
/* 添加一个详情视图大头针 */
KCCalloutAnnotation *annotation1 = [[KCCalloutAnnotation alloc]init];
annotation1.icon = annotation.icon;
annotation1.detail = annotation.detail;
annotation1.rate = annotation.rate;
annotation1.coordinate = annotation.coordinate;
[mapView addAnnotation:annotation1];
}
}
11)取消选中时触发
- (void)mapView:(MKMapView *)mapView didDeselectAnnotationView:(MKAnnotationView *)view
{
[self removeCustomAnnotation];
}
12)移除所有自定义的大头针
- (void)removeCustomAnnotation
{
[self.mapView.annotations enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
if ([obj isKindOfClass:[KCCalloutAnnotation class]]) {
[self.mapView removeAnnotation:obj];
}
}];
}
1.自定义的大头针KCAnnotation
1)引入头文件
#import <MapKit/MapKit.h>
2)需要的属性说明(title,subtitle这两个属性可根据需要保留或者去掉)
/**
* 定义一个model
*/
@interface KCAnnotation : NSObject<MKAnnotation>
@property (nonatomic)CLLocationCoordinate2D coordinate;
@property (nonatomic, copy) NSString *title;
@property (nonatomic, copy) NSString *subtitle;
/* 创建大头针视图的时候使用 */
@property (nonatomic, strong) UIImage *image;
/* 大头针详情左侧图标 */
@property (nonatomic, strong) UIImage *icon;
/* 大头针详情描述 */
@property (nonatomic, strong) NSString *detail;
/* 大头针右下方星级评价 */
@property (nonatomic, strong) UIImage *rate;
@end
2.自定义弹出的大头针KCCalloutAnnotation
1)引入头文件
#import <CoreLocation/CoreLocation.h>
#import <MapKit/MapKit.h>
2)属性和协议的使用
@interface KCCalloutAnnotation : NSObject<MKAnnotation>
@property (nonatomic)CLLocationCoordinate2D coordinate;
/* 设置为只读readonly 弹出的大头针不具备其他作用 */
@property (nonatomic, copy, readonly) NSString *title;
@property (nonatomic, copy, readonly) NSString *subtitle;
/* 左侧图标 */
@property (nonatomic, strong) UIImage *icon;
/* 详情描述 */
@property (nonatomic, copy) NSString *detail;
/* 星级评价 */
@property (nonatomic, strong) UIImage *rate;
@end
3.弹出大头针的自适应(模型:根据系统大头针信息生成自定义大头针)KCCalloutAnnotationView
1)导入头文件
#import <MapKit/MapKit.h>
#import <CoreLocation/CoreLocation.h>
#import "KCCalloutAnnotation.h"
2)属性以及便利构造器(此处会有一个警告,不过不影响,可以忽略)
@interface KCCalloutAnnotationView : MKAnnotationView
@property (nonatomic, strong) KCCalloutAnnotation *annotation;
//便利构造器
+ (instancetype)calloutViewWithMapView:(MKMapView *)mapView;
@end
3)宏定义
#define kSpacing 5
#define kDetailFontSize 12
#define kViewOfset 80
4)大头针的属性
/**
* 自定义弹出的大头针
*/
@interface KCCalloutAnnotationView ()
@property (nonatomic, retain) UIView *backgroundView;
@property (nonatomic, retain) UIImageView *iconView;
@property (nonatomic, retain) UILabel *detailLabel;
@property (nonatomic, retain) UIImageView *rateView;
@end
5)两个初始化方法
/**
* 直接初始化,没有大小
*
* @return 返回一个大头针
*/
- (instancetype)init
{
if (self = [super init]) {
[self layoutUI];
}
return self;
}
- (instancetype)initWithFrame:(CGRect)frame
{
if (self = [super initWithFrame:frame]) {
[self layoutUI];
}
return self;
}
6)UI布局
- (void)layoutUI
{
/* 背景 */
self.backgroundView = [[UIView alloc]init];
self.backgroundView.backgroundColor = [UIColor whiteColor];
/* 左侧图标 */
self.iconView = [[UIImageView alloc]init];
/* 详情 */
self.detailLabel = [[UILabel alloc]init];
self.detailLabel.lineBreakMode = NSLineBreakByCharWrapping;
self.detailLabel.font = [UIFont systemFontOfSize:kDetailFontSize];
/* 星级 */
self.rateView = [[UIImageView alloc]init];
[self addSubview:self.backgroundView];
[self addSubview:self.iconView];
[self addSubview:self.detailLabel];
[self addSubview:self.rateView];
}
7)便利构造器
/**
* 便利构造器 初始化
*
* @param mapView
*
* @return 自定义弹出的大头针
*/
+ (instancetype)calloutViewWithMapView:(MKMapView *)mapView
{
static NSString *calloutkey = @"calloutKey";
KCCalloutAnnotationView *calloutView = (KCCalloutAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:calloutkey];
if (!calloutView) {
calloutView = [[KCCalloutAnnotationView alloc]init];
}
return calloutView;
}
8)设置大头针模型(视图内容)
- (void)setAnnotation:(KCCalloutAnnotation *)annotation
{
[super setAnnotation:annotation];
/* 根据模型调整布局 */
_iconView.image = annotation.icon;
_iconView.frame = CGRectMake(kSpacing, kSpacing, annotation.icon.size.width, annotation.icon.size.height);
_detailLabel.text = annotation.detail;
float detailWidth = 150.0;
CGSize detailSize = [annotation.detail boundingRectWithSize:CGSizeMake(detailWidth, MAXFLOAT) options:NSStringDrawingUsesLineFragmentOrigin attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:kDetailFontSize]} context:nil].size;
float detailX = CGRectGetMaxX(_iconView.frame) + kSpacing;
_detailLabel.frame = CGRectMake(detailX, kSpacing, detailSize.width, detailSize.height);
_rateView.image = annotation.rate;
_rateView.frame = CGRectMake(detailX, CGRectGetMaxY(_detailLabel.frame)+kSpacing, annotation.rate.size.width, annotation.rate.size.height);
float backgroundWidth = CGRectGetMaxX(_detailLabel.frame)+kSpacing;
float backgroundHeight = _iconView.frame.size.height + 2 * kSpacing;
_backgroundView.frame = CGRectMake(0, 0, backgroundWidth, backgroundHeight);
self.bounds = CGRectMake(0, 0, backgroundWidth, backgroundHeight+kViewOfset);
}
运行结果(效果图):
4.图片的处理
