开发iOS最重要的就是支付了,天朝之内最常用的就是支付宝了,下面就以自己的经历说明如何集成支付宝+遇见的坑.

首先,集成支付宝最好别使用Cocoapods,很多人都说使用起来很方便,可是我每次只要使用Cocoapods导入支付宝SDK,总是出现各种莫名其妙的错误,并且还每次都不一样,最终,我只能手动导入.

其实可以使用ping++和其他更为方便.如

https://www.pingxx.com/

以自己集成支付宝为例:

1.在支付宝开放平台下载支付宝SDK,把以下文件直接拷入工程.

2.添加相应的依赖库.选择"target"->"Link Binary With Libraries"

3.编译,坑随之而来,开始填坑.

解决:在相应文件中,导入

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

3.1如果出现

就把官方demo中的下面两个文件拷进工程即可,原因不知.

3.2一般也会出现

,接着导入这个库

 

4.

解决:出现类似找不到文件的情况,Targets->Build Settings->Header Search Path添加路径.

直接将项目中的相应文件拖入即可.也可以$(SRCROOT)/文件路径.

至此,基本的工作完成.下面开始集成代码.

 

首先,在appDelegate.m中

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation {
    //跳转支付宝支付,处理支付结果
//    [[AlipaySDK defaultService]processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
//        NSLog(@"result = %@",resultDic);
//    }];
     
    if ([url.host isEqualToString:@"safepay"]) {
        [[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
            NSLog(@"result = %@",resultDic);
        }];
    }
    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(@"result = %@",resultDic);
        }];
    }
    return YES;
}

 这两个文件直接用官方的即可.

接着,在Controller中,添加另外一个类,这样方便.

 因为我的是点击h5界面上的购买按钮跳转至iOS源生实现购买流程的,所以一些代码可能不同,但是大同小异.

另:因为iOS9的原因,需要配置下项目,如:
