payOrder: fromScheme:方法要回调必须在AppDelegate的- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary*)options里写入processOrderWithPaymentResult才会执行，不然不会回调。 - 网址经过服务器端后部分符号被转义（如
&会被转换成&），需使用HTML转义换成正常的网址，才能使用。
AppDelegate
//微信支付回调
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary*)options
{
if ([url.host isEqualToString:@"safepay"]) {
//一般只需要调用这一个方法即可
[[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
NSLog(@"result1 = %@",resultDic);
// [[NSNotificationCenter defaultCenter] postNotificationName:kAliPayCallBack object:resultDic];
}];
[[AlipaySDK defaultService] processAuth_V2Result:url standbyCallback:^(NSDictionary *resultDic) {
NSLog(@"result2 = %@",resultDic);
NSString *resultStr = resultDic[@"result"];
NSLog(@"result3 = %@",resultStr);
}];
} else if ([url.host isEqualToString:@"platformapi"]){
//支付宝钱包快登授权返回 authCode
[[AlipaySDK defaultService] processAuthResult:url standbyCallback:^(NSDictionary *resultDic) {
NSLog(@"result4 = %@",resultDic);
}];
}
//此处为微信支付回调，与支付宝无关
return [WXApi handleOpenURL:url delegate:[WXApiManager sharedManager]];
}
-
processOrderWithPaymentResult此方法执行则支付方法payOrder: fromScheme:回调执行
