1.监听键盘出现、消失以更改view位置
- (void)keyboardWillShow:(NSNotification *)notification {
CGFloat keyboardHeight = [[notification.userInfo objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue].size.height;//获取键盘高度
CGFloat screenHeight = UIScreen.mainScreen.bounds.size.height;
CGRect customHousePriceViewRect = self.customHousePriceView.frame;
CGFloat offset = customHousePriceViewRect.origin.y + self.view.frame.origin.y - (screenHeight - keyboardHeight - customHousePriceViewRect.size.height - 64);//偏移距离 64是状态栏和导航栏的高度和（20 + 44）
double animateTime = [[notification.userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];//键盘出现的动画时间
if (offset > 0) {
[UIView animateWithDuration:animateTime animations:^{
self.customHousePriceView.frame = CGRectMake(0, customHousePriceViewRect.origin.y-offset, customHousePriceViewRect.size.width, customHousePriceViewRect.size.height);
}];
}
}
- (void)keyboardWillHide:(NSNotification *)notification {
double animateTime = [[notification.userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];//键盘出现的动画时间
[UIView animateWithDuration:animateTime animations:^{
[self loadFrameOfSubViews];
}];
}
