微信支付，首先我们要去微信开放平台申请应用开通支付功能，下载SDK文件

• 我们导入SDK文件

SDK文件

• 加入依赖库

  
  依赖库

• 设置我们的URL Types

  
  URL Types

• 加入白名单，在info.plist中

白名单

• 修改bitcode

  
  bitcode

好了我们可以开始撸代码了

• AppDelegate.m 注册微信
  加入头文件

#import "WXApi.h"

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    [WXApi registerApp:@"wxb4ba3c02aa476ea1" withDescription:@"demo 2.0"];
   
    return YES;
}

    NSString *urlString   = @"http://wxpay.weixin.qq.com/pub_v2/app/app_pay.php?plat=ios";
    //解析服务端返回json数据
    NSError *error;
    //加载一个NSURL对象
    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:urlString]];
    //将请求的url数据放到NSData对象中
    NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
    if ( response != nil) {
        NSMutableDictionary *dict = NULL;
        //IOS5自带解析类NSJSONSerialization从response中解析出数据放到字典中
        dict = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves error:&error];
        
        NSLog(@"url:%@",urlString);
        if(dict != nil){
            NSMutableString *retcode = [dict objectForKey:@"retcode"];
            if (retcode.intValue == 0){
                NSMutableString *stamp  = [dict objectForKey:@"timestamp"];
                
                //调起微信支付
                PayReq* req             = [[PayReq alloc] init];
                req.partnerId           = [dict objectForKey:@"partnerid"];
                req.prepayId            = [dict objectForKey:@"prepayid"];
                req.nonceStr            = [dict objectForKey:@"noncestr"];
                req.timeStamp           = stamp.intValue;
                req.package             = [dict objectForKey:@"package"];
                req.sign                = [dict objectForKey:@"sign"];
                [WXApi sendReq:req];
                //日志输出
                NSLog(@"appid=%@\npartid=%@\nprepayid=%@\nnoncestr=%@\ntimestamp=%ld\npackage=%@\nsign=%@",[dict objectForKey:@"appid"],req.partnerId,req.prepayId,req.nonceStr,(long)req.timeStamp,req.package,req.sign );
//                return @"";
            }else{
//                return [dict objectForKey:@"retmsg"];
            }
        }else{
//            return @"服务器返回错误，未获取到json对象";
        }
    }else{
//        return @"服务器返回错误";
    }

暂时写到这里，这样集成之后基本上可以实现调起微信支付了，等遇到问题在来补充。
