ios能不能微信支付 苹果支持微信支付吗?

      微信支付现在是移动支付领域一支不可忽视的力量，我们移动开发人员在开发app的时候，也不可避免的用到各种支付，支付宝支付我们用的最多了，我这里就不讲解了，我现在给大家讲解一个iOS微信支付，首先 我们需要在微信开放平台注册商户信息(记住是微信开放平台不是公众平台)，微信开放平台支持的银行卡有限，所以在确定用微信支付的时候先看看，支不支持公司的银行卡，比如广大银行卡是不支持的。

      在微信开放平台弄好app支付以后，下载iOS SDK,我们需要配置6个参数 如下图 它在微信支付SDK lib文件夹下的payRequestHandler.h文件中

       把上面那几参数配置好，最下面那2个参数，如果服务器端没配置好可以先不修改，就用微信默认的参数就可以。

      因为微信支付的SDK代码是ARC的，所以我们需要在配置文件里面设置一下，添加-fno-objc-arc  如下图

   

        我们还需要配置一下info里面的URL Types    , URL Schemes里面填写的是APP_ID的值

    

payRequsestHandler.h、WXApi.h   如下图

 我们在AppDelegate.m 实现文件中 写上相应的代码

    我们再在ViewController文件中   添加支付按钮。直接在故事版上面拖上2个按钮就可以。第一个按钮是用的微信服务器返回的json数据 第二个按钮返回的是自己服务器返回的json数据，自己服务器返回的数据包括签名证书一些相关的东西，我们做操作演示  就使用微信的服务器

 

 给按钮加上点击方法。方法在ViewController.m文件中   点击方法的时候会发送一个通知给AppDelegate.m文件

#pragma mark 添加通知
-(void)addObserver
{
    [[NSNotificationCenterdefaultCenter]addObserver:selfselector:@selector(sendPay_demo)name:@"weixinPay"object:nil];
}

#import "ViewController.h"

@interface ViewController ()
- (IBAction)testPay:(id)sender;

- (IBAction)realPay:(id)sender;


@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}


//微信支付测试签名
- (IBAction)testPay:(id)sender {
     [[NSNotificationCenter defaultCenter] postNotificationName:@"weixinPay" object:nil];
}

//微信支付测试签名
- (IBAction)realPay:(id)sender {
   UIAlertView *alert= [[UIAlertView alloc]initWithTitle:@"友情提示" message:@"服务器端接口还没开放，请稍后再试" delegate:nil cancelButtonTitle:@"好的" otherButtonTitles:nil, nil];
    [alert show];
}


@end

发送通知以后，在AppDelegate.h文件的监听方法会调用微信支付  如图

调用起微信支付后，就会打开微信  

 ok,到这里我们的微信支付Demo,就已经做完了，同学们，加油啊。
