iOS app接微信和支付宝 能用吗 苹果支付连接微信

微信支付的开发

前言：之前听说过微信支付有很多坑，其实没有想象的那么坑，整体感觉很容易上手，按照它的流程来不会有错！PS:官方的流程看的TMD烦，好啦，废话有点多，进入开发。（ps:每个微信的版本一直都在更新，这是2015/6/1给你们做的标记

1.    导入微信支付库

微信开放平台新增了微信模块用户统计功能，便于开发者统计微信功能模块的用户使用和活跃情况。开发者需要在工程中链接上:SystemConfiguration.framework,libz.dylib,libsqlite3.0.dylib。

最重要的时这个库：libc++.dylib《ps:官方的文档没说，艹！》

2.在AppDelegate中导入：

（1）#import "WXApi.h"

#import "WXApiObject.h"

遵守WXApiDelegate

在这个方法里注册

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

[WXApi registerApp:WXAppId withDescription:@"yishuPayDes"];


}

（2）跳转处理

- (BOOL)application:(UIApplication *)application

            openURL:(NSURL *)url

  sourceApplication:(NSString *)sourceApplication

         annotation:(id)annotation

{

    NSLog(@"跳转到URL schema中配置的地址-->%@",url);//跳转到URL schema中配置的地址 

    if ([UMSocialSnsService handleOpenURL:url]) {

        return  [UMSocialSnsService handleOpenURL:url];

    }else{

        return [WXApi handleOpenURL:url delegate:self];

    }

}


（3）回调方法

-(void) onResp:(BaseResp*)resp
{

    NSString *strMsg = [NSString stringWithFormat:@"errcode:%d", resp.errCode];

    NSString *strTitle;

    if([resp isKindOfClass:[SendMessageToWXResp class]])
    {
        strTitle = [NSString stringWithFormat:@"发送媒体消息结果"];
    }

    if([resp isKindOfClass:[PayResp class]]){

        //支付返回结果，实际支付结果需要去微信服务器端查询

        strTitle = [NSString stringWithFormat:@"支付结果"];

        

        switch (resp.errCode) {

            case WXSuccess:{

                strMsg = @"支付结果：成功！";

                NSLog(@"支付成功－PaySuccess，retcode = %d", resp.errCode);

                NSNotification *notification = [NSNotification notificationWithName:ORDER_PAY_NOTIFICATION object:@"success"];

                [[NSNotificationCenter defaultCenter] postNotification:notification];

                break;

            }

            default:{

                strMsg = [NSString stringWithFormat:@"支付结果：失败！retcode = %d, retstr = %@", resp.errCode,resp.errStr];

                NSLog(@"错误，retcode = %d, retstr = %@", resp.errCode,resp.errStr);

                NSNotification *notification = [NSNotification notificationWithName:ORDER_PAY_NOTIFICATION object:@"fail"];

                [[NSNotificationCenter defaultCenter] postNotification:notification];

                break;

            }

        }

    }

//    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:strTitle message:strMsg delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];

//    [alert show];

}

说明：这里掌拍艺术App的调试和真机，建议把通知的东西注销，打开alert,方便测试，便于检查回调错误信息，如果你够牛，可以无视，代码难看，见谅，但是人很帅，哈哈！

（4）.接下来在需要支付的界面做这些事：

//监听通知

- (void)viewWillAppear:(BOOL)animated{

    [self requestDownloadData];

    if([WXApi isWXAppInstalled]) // 判断 用户是否安装微信

    {

        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(getOrderPayResult:) name:ORDER_PAY_NOTIFICATION object:nil];//监听一个通知

    }

    [super viewWillAppear:animated];

}

/*ORDER_PAY_NOTIFICATION*/这个写个宏，全局里写，怎么写？建.h文件！

//移除通知

- (void)viewWillDisappear:(BOOL)animated{

    [[NSNotificationCenter defaultCenter]removeObserver:self]; 

}


开始支付-----→终于等到你，还好没放弃！

1.    预备工作，(1)我这里封装了下载类AF(自己感觉比较方便，亲们自己写下载就好了，因为我们公司的网络数据就那么几种)主要用于请求后台服务器已经做好的数据，请求下来的参数给微信，用于支付！(2)获取每台设备的IP地址,(3)HUD是啥，大家都用过，不说了（ps:HUD特效，自己定义看看那种效果好!）(4)后台做了什么：http://wxpay.weixin.qq.com/pub_v2/app/app_pay.php这个地址给后台参考下，需要的参数都在上面移动端不需要写，如果你要写，我不拦你…哈哈，当练手吧!

2.    代码
#pragma mark - 微信支付

    if([WXApi isWXAppInstalled]) // 判断 用户是否安装微信

       HUD.delegate = self;

        HUD.labelText = @"正在为您支付...";

        [HUD show:YES];

最后：测试，我后悔写这么多了，并没有什么用，我擦！
