首先我们要知道键盘的高度是固定不变的,不过在IOS 5.0 以后键盘的高度貌似不是216了,不过不要紧,我们调整调整就是了:
iPhone | ipad | |
竖屏(portrait) | 216 | 264 |
横屏(landScape) | 140 | 352 |
我们采取的方法就是在textField(有可能是其他控件)接收到弹出键盘事件时把self.view整体上移216px了(我们就以iPhone竖屏为例了)。
- (void)textFieldDidBeginEditing:(UITextField *)textField { //当点触textField内部,开始编辑都会调用这个方法。textField将成为first responder NSTimeInterval animationDuration = 0.30f; CGRect frame = self.view.frame; frame.origin.y -=216; frame.size.height +=216; self.view.frame = frame; [UIView beginAnimations:@"ResizeView" context:nil]; [UIView setAnimationDuration:animationDuration]; self.view.frame = frame; [UIView commitAnimations]; }
- (BOOL)textFieldShouldReturn:(UITextField *)textField {//当用户按下ruturn,把焦点从textField移开那么键盘就会消失了 NSTimeInterval animationDuration = 0.30f; CGRect frame = self.view.frame; frame.origin.y +=216; frame.size. height -=216; self.view.frame = frame; //self.view移回原位置 [UIView beginAnimations:@"ResizeView" context:nil]; [UIView setAnimationDuration:animationDuration]; self.view.frame = frame; [UIView commitAnimations]; [textField resignFirstResponder]; }
