Foundation-结构体

#import <Foundation/Foundation.h>

void test(){
    //定义一种结构体
    struct Date{
        int Year;
        int Month;
        int Day;
    };
    struct Date d={2013,5,4};
    d.Day=5;
}

void test1(){
    //宏定义
    typedef struct Date{
        int Year;
        int Month;
        int Day;
    } MyDate;

    MyDate day={2013,1,1};
    
}


void NSRangeTest(){
    //NSRange是一个结构体，里面有两个成员，一个位置还有一个表示长度
    NSRange range={3,1};
    NSRange range1=NSMakeRange(6, 3);
    NSLog(@"location:%zi",range1.location);  //NSRange参数类型是NSUInteger 就是Unsigned long类型 访问的话为@zi 
    NSLog(@"length:%zi",range1.length);

    //还有一种NSString打印方法
    NSString *str=NSStringFromRange(range);
    NSLog(@"range:%@",str);
}

void pointTest(){
    NSPoint point={10,10};
    point=NSMakePoint(11, 11);
    point=CGPointMake(12, 12);//最常用
    CGPoint point1;  //NSPoint和CGPoint是等价的
    point1.x=11;
    point1.y=12;
    NSString *str=NSStringFromPoint(point);
    NSLog(@"%@",str);
    NSString *str1=NSStringFromPoint(point1);
    NSLog(@"point:%@",str1);
}

void sizeTest(){
    //创建一个宽度为10，高度是8的size
    NSSize size=CGSizeMake(10, 8);
    size=NSMakeSize(11, 9);
    size.width=12;
    size.height=10;
    NSString *str=NSStringFromSize(size);
    NSLog(@"size:%@",str);
}

void rectTest(){
    //创建一个左边为多少的长方体
    CGRect rect1=CGRectMake(1, 1, 10, 10);
    NSRect rect=CGRectMake(10, 10, 12, 9);
    rect.origin.x=11;
    rect.origin.y=11;
    rect.size.width=100;
    rect.size.height=90;
    NSString *str=NSStringFromRect(rect);
    NSLog(@"rect:%@",str);
    NSString *str1=NSStringFromRect(rect1);
    NSLog(@"rect:%@",str1);
}
int main(int argc, const char * argv[])
{

    @autoreleasepool {
        NSRangeTest();
        pointTest();
        sizeTest();
        rectTest();
    }
    return 0;
}
