TTMessageController不能設置它的文本編輯爲firstResponder

Question

我有TTMessageController這是（CommentViewController）的子類，我有以下映射

[map from:@"tt://postDetails/(initWithPostId:)/(anotherId:)" toViewController:[PostDetailsViewController class]]; 
[map from:@"tt://groupBoardAddComment/(initWithPostId:)/(anotherId:)" toModalViewController:[CommentViewController class]]; 

當我打電話CommentViewController從我PostDetailsViewController類，它的鍵盤不會出現，但是當我把它從它的鍵盤出現我的其他視圖控制器類，

即使我試圖以武力becomeFirstResponder它的文本編輯在所有viewWillAppear中，viewDidLoad中和等米我的CommentViewController方法，仍然無法顯示。

希望回覆，真的需要這方面的幫助，感謝

這裏的問題是，我調用該方法時，用戶在我的文本框開始，而不是文本字段的編輯，我把它用選擇器更改爲一個按鈕調用並顯示CommentViewController，

代替此

- (IBAction)textFieldDidBeginEditing:(id)sender { 
    CommentViewController *commentViewController = [[CommentViewController alloc] initWithPostId:self.postId groupId:self.groupId]; 

    UINavigationController *navigationController = [[UINavigationController alloc] 
               initWithRootViewController:commentViewController]; 
    [self presentModalViewController:navigationController animated:YES]; 
    [navigationController release]; 
    [commentViewController release]; 
} 

我由方法通過一個按鈕被稱爲選擇器

-(void) displayCommentView 
    CommentViewController *commentViewController = [[CommentViewController alloc] initWithPostId:self.postId groupId:self.groupId]; 

    UINavigationController *navigationController = [[UINavigationController alloc] 
                initWithRootViewController:commentViewController]; 
    [self presentModalViewController:navigationController animated:YES]; 
    [navigationController release]; 
    [commentViewController release];
