关于ios：键盘出现时查看不向上移动

View not moving up when keyboard appears

本问题已经有最佳答案，请猛点这里访问。

我在子视图中有一个ui文本字段。我正在将它添加到视图中。当键盘弹出时，我想使我要添加此子视图的视图具有动画效果。我只在子视图类中编写了所有textfield委托函数。因此，如果我使用animate文本字段函数，它不会移动父视图，而会使子视图具有动画效果……请帮助我

[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardWillShow:)
name:UIKeyboardWillShowNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardWillHide:)
name:UIKeyboardWillHideNotification
object:nil];

在viewDidLoad中

- (void)keyboardWillHide:(NSNotification *)aNotification
{
// the keyboard is hiding reset the table's height
NSTimeInterval animationDuration =
[[[aNotification userInfo] objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];
CGRect frame = self.view.frame;
frame.origin.y += 160;
[UIView beginAnimations:@"ResizeForKeyboard" context:nil];
[UIView setAnimationDuration:animationDuration];
self.view.frame = frame;
[UIView commitAnimations];
}

- (void)keyboardWillShow:(NSNotification *)aNotification
{
// the keyboard is showing so resize the table's height
NSTimeInterval animationDuration =
[[[aNotification userInfo] objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];
CGRect frame = self.view.frame;
frame.origin.y -= 160;
[UIView beginAnimations:@"ResizeForKeyboard" context:nil];
[UIView setAnimationDuration:animationDuration];
self.view.frame = frame;
[UIView commitAnimations];
}

在视图控制器中

最有可能的情况是，您必须根据您的具体视图更改我在此处放置的值(160)。
