使UIImageView充當Facebook登錄按鈕

Question

在我的main.storyboard我有一個UIImage視圖，這只是一個通用的Facebook登錄按鈕。不過，我很困惑，因爲使用這些通用的步驟

override func viewDidLoad(){ 
{ 
    super.viewDidLoad() 
    var imageView = <# imageView #> 
    let tapGestureRecognizer = UITapGestureRecognizer(target:self, action:Selector("imageTapped:")) 
    imageView.userInteractionEnabled = true 
    imageView.addGestureRecognizer(tapGestureRecognizer) 
} 

func imageTapped(img: AnyObject) 
{ 
// The Action 
} 

我有點失去了，什麼The Action會在這種情況下，我需要通過Facebook的SDK鏈接的一切。

Answer 1

-(void)imgtapped 
{ 
     FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init]; 
    [login 
    logInWithReadPermissions: @[@"public_profile"] 
      fromViewController:self 
        handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) { 
      if (error) { 
       NSLog(@"Process error"); 
      } else if (result.isCancelled) { 
       NSLog(@"Cancelled"); 
      } else { 
       NSLog(@"Logged in"); 
      } 
    }]; 
} 

Answer 2

在你imageTapped

func imageTapped() { 
     let manager = FBSDKLoginManager() 
     manager.logInWithReadPermissions(["public_profile"], fromViewController: self, handler: { result, error in 
     if error != nil { 
      print("process error") 
     } else if result.isCancelled { 
      print("cancelled log in") 
     } else { 
      print("logged in") 
     } 
    }) 
}
