我的 UI 在显示键盘时需要进行一些位置调整。
以下用于检测何时显示键盘:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardWillShow:)
name:UIKeyboardWillShowNotification
object:nil];
注意:我已经尝试过 UIKeyboardWillShowNotification 和 UIKeyboardDidShowNotification
- (void)keyboardWillShow:(NSNotification *)n {
if (isKeyboardShowing)
return;
NSDictionary* userInfo = [n userInfo];
// get the size of the keyboard
CGSize keyboardSize = [[userInfo objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
// Animate keyboard shift
[self.view layoutIfNeeded];
[UIView animateWithDuration:0.2f animations:^{
// some animation here
} completion:^(BOOL finished) {
if (finished)
isKeyboardShowing = YES;
}];
对于自定义键盘，键盘大小返回 {320, 0}。由于键盘现在可以有不同的高度，因此我无法在出现键盘时使用静态值来更改 UI。
这是 ios8 的问题吗？还有其他动态获取键盘高度的方法吗？
编辑:这是 userInfo Dict:
{name = UIKeyboardDidShowNotification; userInfo = {
UIKeyboardAnimationCurveUserInfoKey = 7;
UIKeyboardAnimationDurationUserInfoKey = "0.25";
UIKeyboardBoundsUserInfoKey = "NSRect: {{0, 0}, {320, 0}}";
UIKeyboardCenterBeginUserInfoKey = "NSPoint: {160, 568}";
UIKeyboardCenterEndUserInfoKey = "NSPoint: {160, 568}";
UIKeyboardFrameBeginUserInfoKey = "NSRect: {{0, 568}, {320, 0}}";
UIKeyboardFrameEndUserInfoKey = "NSRect: {{0, 568}, {320, 0}}";
}}
提前致谢。
