鍵盤出現(xiàn)實(shí)現(xiàn)textfield的代理方法- (void)textFieldDidBeginEditing:(UITextField *)textField{ CGRect frame = textField.frame; CGPoint rootFrame = [[textField superview] convertPoint:frame.origin toView:self.view];//把控件的坐標(biāo)轉(zhuǎn)為相對(duì)于屏幕的坐標(biāo) int offset = rootFrame.y + 56 - (self.view.frame.size.height - 216.0);//鍵盤高度216 NSTimeInterval animationDuration = 0.30f; [UIView beginAnimations:@"ResizeForKeyBoard" context:nil]; [UIView setAnimationDuration:animationDuration]; float width = self.view.frame.size.width; float height = self.view.frame.size.height; if(offset > 0){ CGRect rect = CGRectMake(0.0f, -offset,width,height); self.view.frame = rect; } [UIView commitAnimations];}鍵盤收起- (IBAction)hideKeyboard:(id)sender { NSTimeInterval animationDuration = 0.30f; [UIView beginAnimations:@"ResizeForKeyboard" context:nil]; [UIView setAnimationDuration:animationDuration]; CGRect rect = CGRectMake(0.0f, 0.0f, self.view.frame.size.width, self.view.frame.size.height); self.view.frame = rect; [UIView commitAnimations]; //在這把textField的第一焦點(diǎn)去掉}
