微信支付流程(IOS)

1.注册微信开发账号,开通支付权限(注册谁都会了)

2.把三个文件拉进去

libWeChatSDK.a

WXApi.h

WXApiObject.h

3.添加URL Types

4.AppDelegate.m中添加微信账号

[WXApiregisterApp:@"wxalsdfjalsfals"withDescription:@"tencent”];

    return  [WXApihandleOpenURL:urldelegate:self];
}

    return  [WXApihandleOpenURL:urldelegate:self];
}

- (void)onResp:(BaseResp*)resp {
    if ([resp isKindOfClass:[PayRespclass]]) {
        PayResp *response = (PayResp*)resp;
        switch (response.errCode) {
            case WXSuccess:
                NSLog(@"suceess");
                break;
            default:
                NSLog(@"failed");
                break;
        }
