1翼抠、集成SDK：
下載并解壓SDK?:下載鏈接咙轩。

2、添加依賴庫
SystemConfiguration.framework
libz.tbd
libc++.tbd
CoreTelephony.framework
CFNetwork.framework
Security.framework
UIKit.framework
Foundation.framework
CoreGraphics.framework
CoreMotion.framework
CoreText.framework

3阴颖、新增?一條URL Scheme:選中?工程Target -> Info -> URLTypes;
identifier隨便寫臭墨，URL scheme此時也可以隨便填寫，但是要保證調(diào)起支付的方法里傳的appScheme參數(shù)和這里填寫的一致

支付寶URL scheme

調(diào)起支付的方法中的參數(shù)scheme要和URL scheme配置中填寫的一樣

4膘盖、添加?白名單:LSApplicationQueriesSchemes新增?名單

支付寶白名單

5、在支付頁面獲取到支付所需要的參數(shù)后調(diào)用支付方法

   /**
     *  支付寶支付
     */
-(void)handleOrderPayWithParams:(NSDictionary *)aParam
    {
        NSLog(@"aParm = %@",aParam);
        //這里的appScheme一定要與URL  Scheme中的一致
        NSString *appScheme = @"alisdkofshuyinHotel";
        NSString *orderString = aParam[@"orderInfo"];
        // NOTE: 調(diào)用支付結(jié)果開始支付
        [[AlipaySDK defaultService] payOrder:orderString fromScheme:appScheme callback:^(NSDictionary *resultDic) {
            NSLog(@"reslut = %@",resultDic);
            int statusCode = [resultDic[@"resultStatus"]  intValue];
            if (statusCode == 9000) {
                //訂單支付
                [SVProgressHUD showSuccessWithStatus:@"支付成功尤误！"];
                [[NSNotificationCenter defaultCenter] postNotificationName:@"paySuccess" object:nil];
            }else {
                //交易失敗
                // [[NSNotificationCenter defaultCenter] postNotificationName:@"PAY_STATUS" object:@"0"];
                [SVProgressHUD showErrorWithStatus:@"支付異常！"];
            }
        }];
    }

6喘落、appDelegate中處理回調(diào)結(jié)果

//iOS9.0以前
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
    if ([url.host isEqualToString:@"safepay"]) {
        // 支付跳轉(zhuǎn)支付寶錢包進行支付暖哨，處理支付結(jié)果
        [[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
            NSLog(@"result = %@",resultDic);
        }];
        // 授權(quán)跳轉(zhuǎn)支付寶錢包進行支付，處理支付結(jié)果
        [[AlipaySDK defaultService] processAuth_V2Result:url standbyCallback:^(NSDictionary *resultDic) {
            NSLog(@"result = %@",resultDic);
            // 解析 auth code
            NSString *result = resultDic[@"result"];
            NSString *authCode = nil;
            if (result.length>0) {
                NSArray *resultArr = [result componentsSeparatedByString:@"&"];
                for (NSString *subResult in resultArr) {
                    if (subResult.length > 10 && [subResult hasPrefix:@"auth_code="]) {
                        authCode = [subResult substringFromIndex:10];
                        break;
                    }
                }
            }
            NSLog(@"授權(quán)結(jié)果 authCode = %@", authCode?:@"");
        }];
    }
    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
{
    if ([url.host isEqualToString:@"safepay"]) {
        // 支付跳轉(zhuǎn)支付寶錢包進行支付黍聂，處理支付結(jié)果
        [[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
            NSLog(@"result = %@",resultDic);
            if ([resultDic[@"resultStatus"] integerValue] == 9000) {
                [SVProgressHUD showSuccessWithStatus:@"支付成功！"];
                PaySucceedViewController *vc = [[PaySucceedViewController alloc] init];
                vc.backStr = @"1";
                UINavigationController *navi = [[UINavigationController alloc] initWithRootViewController:vc];
                [self.tb presentViewController:navi animated:NO completion:nil];
            }else{
                [SVProgressHUD showSuccessWithStatus:@"支付異常！"];
                PayFailedViewController *vc = [[PayFailedViewController alloc] init];
                vc.backStr = @"1";
                UINavigationController *navi = [[UINavigationController alloc] initWithRootViewController:vc];
                [self.tb presentViewController:navi animated:NO completion:nil];
            }
        }];
        
        // 授權(quán)跳轉(zhuǎn)支付寶錢包進行支付，處理支付結(jié)果
        [[AlipaySDK defaultService] processAuth_V2Result:url standbyCallback:^(NSDictionary *resultDic) {
            NSLog(@"result = %@",resultDic);
            // 解析 auth code
            NSString *result = resultDic[@"result"];
            NSString *authCode = nil;
            if (result.length>0) {
                NSArray *resultArr = [result componentsSeparatedByString:@"&"];
                for (NSString *subResult in resultArr) {
                    if (subResult.length > 10 && [subResult hasPrefix:@"auth_code="]) {
                        authCode = [subResult substringFromIndex:10];
                        break;
                    }
                }
            }
            NSLog(@"授權(quán)結(jié)果 authCode = %@", authCode?:@"");
        }];
    }
    return YES;
