切换到另一个视图时隐藏键盘

Question

我有 2 个视图，登录和注册。

我做了 [currentTextField resignFirstResponder];在我导航到另一个视图之前。

问题是，键盘只有在切换视图后才会隐藏。因此，在另一个视图上触发了 KeyboardDidShow 方法，这导致了混乱。

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?

我想知道为什么当我明确地将它放在它上面时，它在切换视图后才辞职。

-(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];

}

您可以在进入第二个视图之前延迟一些，以便键盘会隐藏。 try [self PerformSelector: withObject: afterDelay:0.35];//在调用此退出当前文本字段之前传递像@selector(displaySecondView)这样的选择器。
