前言：關(guān)于支付寶的集成就看螞蟻金服的集成步驟走就好了。這里只提一下其他問題。

1. 喚起支付寶
2. 支付寶支付成功后無法返回app
3. 支付成功后回調(diào)

// 就是下面的orderString

-> objectName即你的工程名稱

1. 喚起支付寶

[[AlipaySDK defaultService] payOrder:orderString fromScheme:@"objectName" callback:^(NSDictionary *resultDic) {
        
}];

2. 支付寶支付成功后無法返回app，需要設(shè)置如下圖：

3. 支付成功后回調(diào)

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
    // 微信支付回調(diào)
    [WXApi handleOpenURL:url delegate:[WXApiManager sharedManager]];
    //支付寶回調(diào)
    if ([url.host isEqualToString:@"safepay"]) {
        //跳轉(zhuǎn)支付寶錢包進(jìn)行支付，處理支付結(jié)果
        [[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
            NSLog(@"result1 = %@",resultDic);
            [self zhifubaoIsPay_status:resultDic[@"resultStatus"]];
        }];
    }
    return YES;
}
// NOTE: 9.0以后使用新API接口
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString*, id> *)options
{
    // 微信支付回調(diào)
    [WXApi handleOpenURL:url delegate:self];
    //支付寶回調(diào)
    if ([url.host isEqualToString:@"safepay"]) {
        //跳轉(zhuǎn)支付寶錢包進(jìn)行支付，處理支付結(jié)果
        [[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
            NSLog(@"result2 = %@",resultDic);
            [self zhifubaoIsPay_status:resultDic[@"resultStatus"]];
        }];
    }
    return YES;
}
