这是个老生常谈的问题,但是之前监听键盘通知总会遇到各种问题。这里记录下自己目前使用没出现问题的解决办法。直接上代码
#pragma mark - 键盘通知
- (void)addNoticeForKeyboard {
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardFrameChange:) name:UIKeyboardWillChangeFrameNotification object:nil];
}
//键盘farme值
- (void)keyboardFrameChange:(NSNotification *)notifi{
NSDictionary *userInfo = notifi.userInfo;
CGRect endFrame = [userInfo[UIKeyboardFrameEndUserInfoKey] CGRectValue];
CGRect beginFrame = [userInfo[UIKeyboardFrameBeginUserInfoKey] CGRectValue];
CGFloat duration = [userInfo[UIKeyboardAnimationDurationUserInfoKey] doubleValue];
UIViewAnimationCurve curve = [userInfo[UIKeyboardAnimationCurveUserInfoKey] integerValue];
void(^animations)(void) = ^{
[self willShowKeyboardFromFrame:beginFrame toFrame:endFrame];
};
void(^completion)(BOOL) = ^(BOOL finished){
};
[UIView animateWithDuration:duration delay:0.0f options:(curve << 16 | UIViewAnimationOptionBeginFromCurrentState) animations:animations completion:completion];
}
- (void)willShowKeyboardFromFrame:(CGRect)beginFrame toFrame:(CGRect)toFrame
{
if (toFrame.origin.y == [[UIScreen mainScreen] bounds].size.height){//键盘收起
}else{ //键盘升起
keyboardHeight = toFrame.size.height;
}
}
谢谢。最近真是忙啊,心好累!
