iOS開發:集成支付寶(遇見的坑和便捷擼代碼)

開發iOS最重要的就是支付了,天朝之內最常用的就是支付寶了,下面就以自己的經歷說明如何集成支付寶+遇見的坑.

首先,集成支付寶最好別使用Cocoapods,很多人都說使用起來很方便,可是我每次只要使用Cocoapods導入支付寶SDK,總是出現各種莫名其妙的錯誤,並且還每次都不一樣,最終,我只能手動導入.

其實可以使用ping++和其他更為方便.如

以自己集成支付寶為例:

1.在支付寶開放平台下載支付寶SDK,把以下文件直接拷入工程.

2.添加相應的依賴庫.選擇"target"->"Link Binary With Libraries"

3.編譯,坑隨之而來,開始填坑.

解決:在相應文件中,導入

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

3.1如果出現

就把官方demo中的下面兩個文件拷進工程即可,原因不知.

3.2一般也會出現

,接着導入這個庫

 

4.

解決:出現類似找不到文件的情況,Targets->Build Settings->Header Search Path添加路徑.

直接將項目中的相應文件拖入即可.也可以$(SRCROOT)/文件路徑.

至此,基本的工作完成.下面開始集成代碼.

 

首先,在appDelegate.m中

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation {
    //跳轉支付寶支付,處理支付結果
//    [[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"]){//支付寶錢包快登授權返回 authCode
        [[AlipaySDK defaultService] processAuthResult:url standbyCallback:^(NSDictionary *resultDic) {
            NSLog(@"result = %@",resultDic);
        }];
    }
    return YES;
}

 這兩個文件直接用官方的即可.

接着,在Controller中,添加另外一個類,這樣方便.

 因為我的是點擊h5界面上的購買按鈕跳轉至iOS源生實現購買流程的,所以一些代碼可能不同,但是大同小異.

另:因為iOS9的原因,需要配置下項目,如:

這就是基本的支付寶集成了.
