切換到另一個視圖時隱藏鍵盤

Question

我有2個視圖，登錄和註冊。

我做了[currentTextField resignFirstResponder];在我導航到另一個視圖之前。

問題是，鍵盤僅在切換視圖後隱藏。因此在另一個視圖上觸發了keyboardDidShow方法，這種方法混亂了。

2011-07-19 18:55:33.315 Prime Taxi Booking[601:207] Login view appear // lauched app 
2011-07-19 18:55:34.952 Prime Taxi Booking[601:207] Login Keyboard appear // starts typing 
2011-07-19 18:55:37.033 Prime Taxi Booking[601:207] Register view appeared // navigation 
2011-07-19 18:55:37.036 Prime Taxi Booking[601:207] Login view disappear 
2011-07-19 18:55:37.360 Prime Taxi Booking[601:207] Register Keyboard disappear // ?? how do I make this to disappear login keyboard instead? 

我不知道爲什麼它只有在切換視圖後纔會resignFirstResponder，當我清楚地將它放在它上面時。

-(IBAction) registerButton:(id) sender 
{ 
[currentTextField resignFirstResponder]; 
Registers *registerview = [[Registers alloc] initWithNibName:nil bundle:nil]; 
[UIView beginAnimations:@"flipping view" context:nil]; 
[UIView setAnimationDuration:1]; 
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn]; 
[UIView setAnimationTransition: UIViewAnimationTransitionCurlUp 
         forView:self.view.superview 
         cache:YES]; 

[UIView commitAnimations]; 

[self presentModalViewController:registerview animated:YES]; 

//[self.view addSubview:registerview.view]; 

}

你可以把一些延遲纔去第二個觀點，這樣鍵盤會隱藏。嘗試[self performSelector：withObject：afterDelay：0.35]; //在調用此resign當前文本字段之前傳遞選擇器，如@selector（displaySecondView）。
