키보드가 cocos2d에 uitextfield를 표시하지 않습니다.

Question

표시 할 코드는 다음과 같습니다.

UIViewController* viewControoler = [[UIViewController alloc]init]; 
textfield = [[UITextField alloc]initWithFrame:CGRectMake(0,0,280,90)]; 
textfield.placeholder = @"word"; 
textfield.keyboardType = UIKeyboardTypeDefault; 
textfield.returnKeyType = UIReturnKeySearch; 
textfield.clearButtonMode = UITextFieldViewModeWhileEditing; 
textfield.delegate = self; 
textfield.userInteractionEnabled = YES; 
[textfield becomeFirstResponder]; 
[viewControoler.view addSubview:textfield]; 
[[[CCDirector sharedDirector]openGLView] addSubview:viewControoler.view]; 

잘 돌아갑니다. 그러나 uitextfiled를 클릭 할 때 키보드가 오지 않기 때문에 텍스트 필드를 편집 할 수 없습니다.

Answer 1

, OpenGLView에 추가 직접 UIViewController에 제거

textfield = [[UITextField alloc]initWithFrame:CGRectMake(0,0,280,90)]; 
textfield.placeholder = @"word"; 
textfield.keyboardType = UIKeyboardTypeDefault; 
textfield.returnKeyType = UIReturnKeySearch; 
textfield.clearButtonMode = UITextFieldViewModeWhileEditing; 
textfield.delegate = self; 
textfield.userInteractionEnabled = YES; 
[textfield becomeFirstResponder]; 

[[[CCDirector sharedDirector]openGLView] addSubview:textfield;
