Ios FBSDKGameRequestDialog發送取消方法事件

Question

FBSDKGameRequestContent *content = [[FBSDKGameRequestContent alloc]init]; 
content.message = @"Great FB"; 
content.title = @"Invite Friends"; 
FBSDKGameRequestDialog *gameDialog = [[FBSDKGameRequestDialog alloc]init]; 
gameDialog.content = content; 
gameDialog.frictionlessRequestsEnabled = YES; 
gameDialog.delegate = self; 
if ([gameDialog canShow]) { 
    [gameDialog show]; 
} 

我正在使用上面的代碼來顯示FBFriends。該對話框已打開，但我想在用戶點擊發送/取消後執行一些自定義功能。 我該怎麼做？

Answer 1

你這樣做：

gameDialog.delegate = self; 

那麼，你爲什麼不使用委託方法（FBSDKGameRequestDialogDelegate）：gameRequestDialogDidCancel:和 gameRequestDialog:didCompleteWithResults:知道，如果用戶已經取消了發送邀請的？

在你YourCurrentClass.h：

@interface YourCurrentClass : NSObject <FBSDKGameRequestDialogDelegate> 

在你YourCurrentClass.m：

- (void)gameRequestDialog:(FBSDKGameRequestDialog *)gameRequestDialog 
didCompleteWithResults:(NSDictionary *)results 
{ 
    //User has done something. 
    //Check "results" and do something. 
} 

- (void)gameRequestDialogDidCancel:(FBSDKGameRequestDialog *)gameRequestDialog 
{ 
    //User has cancelled 
    //Do somathing 
} 

- (void)gameRequestDialog:(FBSDKGameRequestDialog *)gameRequestDialog 
didFailWithError:(NSError *)error 
{ 
    //An error happened 
    NSLog(@"Error: %@", error); 
    //Do something 
}
