整合谷歌和Facebook登錄iOS中 - AppDelegate中的OpenURL

Question

我想Facebook和谷歌登錄融入我的應用程序，但有一個問題：這都需要以下添加到在AppDelegate中OpenURL方法：

return [GIDSignIn sharedInstance] handleURL:url 
          sourceApplication:sourceApplication 
             annotation:annotation]]; 

return [FBSDKApplicationDelegate sharedInstance] application:application 
                 openURL:url 
              sourceApplication:sourceApplication 
                annotation:annotation 
     ]] 

是否有這些都正常工作。我在網上看了但答案是相當模糊，並不能提供一個很好的解釋

解決方案

添加了的伎倆對我下面的（如iOS版9）：

return [[GIDSignIn sharedInstance] handleURL:url sourceApplication:sourceApplication annotation:annotation] || [[FBSDKApplicationDelegate sharedInstance] application:application openURL:url sourceApplication:sourceApplication annotation:annotation ]; 

Answer 1

使用下面的代碼...

- (BOOL)application:(UIApplication *)applicationopenURL:(NSURL *)url 
     sourceApplication:(NSString *)sourceApplicationannotation:(id)annotation 
    { 
     if ([FBAppCall handleOpenURL:url sourceApplication:sourceApplication]) 
     return [FBSDKApplicationDelegate sharedInstance] application:application 
                 openURL:url 
              sourceApplication:sourceApplication 
                annotation:annotation 
     ]]; 
     else 

     return [GIDSignIn sharedInstance] handleURL:url 
          sourceApplication:sourceApplication 
             annotation:annotation]]; 
    } 

另一個答案..

- (BOOL)application:(UIApplication *)applicationopenURL:(NSURL *)url 
    sourceApplication:(NSString *)sourceApplicationannotation:(id)annotation 
{ 

    NSString *stringURL = [ url absoluteString]; 
    if([stringURL containsString:@"fb"]) 
    { 


    return [[FBSDKApplicationDelegate sharedInstance] application:application 
                  openURL:url 
               sourceApplication:sourceApplication 
                 annotation:annotation]; 
    } 
    else 
    { 
     return [GPPURLHandler handleURL:url 
         sourceApplication:sourceApplication 
          annotation:annotation]; 

    } 
}
