支付宝支付集成方法

1.将项目中的AliSDK与AliPayTool文件夹拖入自己的项目中

2.在Build Phases选项卡的Link Binary With Libraries中，增加以下依赖：

3.到MXAlipayConfig.h配置支付宝支付所需要的参数

4.导入头文件MXAlipayConfig.h

5.在AppDelegate.m实现以下代码

#import "AppDelegate.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    return YES;
}

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation
{
    if ([url.host isEqualToString:@"safepay"]) {
        [self paymentResult:url];
    }
    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"]) {
        [self paymentResult:url];
    }
    return YES;
}

- (void)paymentResult:(NSURL *)url
{
    //跳转支付宝钱包进行支付，处理支付结果
    [[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
        NSLog(@"result = %@",resultDic);
    }];
}

@end

6.在需要调起微信支付的界面编写以下代码

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
    [MXAliPayHandler jumpToAliPay];
}
