相信大家都會遇到在工程中有輸入框，而鍵盤彈起時會被遮擋的情況，在這里給大家介紹一個用動畫的方法使頁面上移，直接上代碼：

#pragma mark - 屏幕上彈
-(void)textFieldDidBeginEditing:(UITextField *)textField
{
    //鍵盤高度216
    if (textField == _verificationCodeTextField.myTextField || textField == _registationTextField.myTextField) {
        //滑動效果（動畫）
        NSTimeInterval animationDuration = 0.30f;
        [UIView beginAnimations:@"ResizeForKeyboard" context:nil];
        [UIView setAnimationDuration:animationDuration];
        
        //將視圖的Y坐標向上移動，以使下面騰出地方用于軟鍵盤的顯示
        self.frame = CGRectMake(0.0f, -208.f, self.frame.size.width, self.frame.size.height);//64-216
        [UIView commitAnimations];
        
    }
}

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