iOS--->微信支付小结
iOS--->微信支付小结
说起支付，除了支付宝支付之外，微信支付也是我们三方支付中最重要的方式之一，承接上面总结的支付宝，接下来把微信支付也总结了一下
***那么首先还是由公司去创建并申请使用微信支付所需的信息
1.接下来就是微信支付的集成步骤了，参考着开发文档来，非常简单的 下载SDK，项目中导入所需的文件WxPay文件夹中，注意其中的.a文件容易丢失
2.根据文档对其中支持的非arc进行设置
3.设置微信支付的URL types
4.接下来就是代码内部的事情了，做支付我们知道首先需要在appdelegate中设置相应的属性
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
//微信支付配置 自己申请注册的
[WXApi registerApp:@"wx0e65e1b96577f407" withDescription:@"demo 2.0"];
return YES;
}
//微信支付界面 onResp函数回调界面
//处理微信通过URL，启动App时传递的数据
-(BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url{
return [WXApi handleOpenURL:url delegate:self];
}
说到支付，那么支付结果的回调是必不可少的，还是在appdelegate页面
//微信支付返回 回调
-(void)onResp:(BaseResp*)resp{
NSLog(@"tets");
NSInteger num=0;
if ([resp isKindOfClass:[PayResp class]]){
PayResp*response=(PayResp*)resp;
switch(response.errCode){
case WXSuccess:
{
num=1;
//服务器端查询支付通知或查询API返回的结果再提示成功
NSLog(@"支付成功");
// [self weixinzhifuhuidiao:1];
break;
}
case WXErrCodeUserCancel:
{
num=2;
NSLog(@"cewsgu");
// [self weixinzhifuhuidiao:2];
}
break;
default:
num=3;
// [self weixinzhifuhuidiao:3];
NSLog(@"支付失败，retcode=%d",resp.errCode);
break;
}
}
}
最后就不说闲话了，直接在支付页面上代码参考官方Demo即可(貌似官方有两种方式，这里仅使用其中一种)
