这块还有点去处理的地方,就是方便代码集中需要统一去处理一下各种第三方的回调
在appdelegate.m的收到回调的方法中统一处理
#pragma mark -- 第三方回调相关 (支付,友盟)
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url
{
[PaysTool payHandleOpenURL:url];
BOOL result = [[UMSocialManager defaultManager] handleOpenURL:url];
return result;
}
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation
{
[PaysTool payHandleOpenURL:url];
return [[UMSocialManager defaultManager] handleOpenURL:url];
}
-(BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {
[URLSchemTool handleOpenURL:url];
[PaysTool payHandleOpenURL:url];
return [[UMSocialManager defaultManager] handleOpenURL:url];
}
[PaysTool payHandleOpenURL:url];在这里集中代码
#pragma mark -- //支付回调
+(void)payHandleOpenURL:(NSURL *)url{
[WXApi handleOpenURL:url delegate:(id)[IPayTool shareInstance]];
[[IapppayKit sharedInstance] handleApplicationOpenUrl:url];
[[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
LOG(@"result = %@",resultDic);//返回的支付结果 //【由于在跳转支付宝客户端支付的过程中,商户 app 在后台很可能被系统 kill 了,所以 pay 接 口的 callback 就会失效,请商户对 standbyCallback 返回的回调结果进行处理,就是在这个方法 里面处理跟 callback 一样的逻辑】
if ([IPayTool shareInstance].aliCallback) {
[IPayTool shareInstance].aliCallback(resultDic);
}
}];
}
[IPayTool shareInstance]就是最上边创建的支付工具,在里边发请求同时处理回调,让代码集中,方便处理实际的业务
