相信大家都会遇到在工程中有输入框，而键盘弹起时会被遮挡的情况，在这里给大家介绍一个用动画的方法使页面上移，直接上代码：

#pragma mark - 屏幕上弹
-(void)textFieldDidBeginEditing:(UITextField *)textField
{
    //键盘高度216
    if (textField == _verificationCodeTextField.myTextField || textField == _registationTextField.myTextField) {
        //滑动效果（动画）
        NSTimeInterval animationDuration = 0.30f;
        [UIView beginAnimations:@"ResizeForKeyboard" context:nil];
        [UIView setAnimationDuration:animationDuration];
        
        //将视图的Y坐标向上移动，以使下面腾出地方用于软键盘的显示
        self.frame = CGRectMake(0.0f, -208.f, self.frame.size.width, self.frame.size.height);//64-216
        [UIView commitAnimations];
        
    }
}

#pragma mark -屏幕恢复
-(void)textFieldDidEndEditing:(UITextField *)textField {
    if (textField == _verificationCodeTextField.myTextField || textField == _registationTextField.myTextField) {
    //滑动效果
    NSTimeInterval animationDuration = 0.30f;
    [UIView beginAnimations:@"ResizeForKeyboard" context:nil];
    [UIView setAnimationDuration:animationDuration];
    
    //恢复屏幕
    self.frame = CGRectMake(0.0f, 0.0f, self.frame.size.width, self.frame.size.height);//64-216
    
    [UIView commitAnimations];
}
}
