我要疯了。当键盘出现时，我将尝试使用其文本字段移动工具栏。使用以下代码，视图确实在移动，但 ToolBar 保持不动并被键盘隐藏：

- (void) liftMainViewWhenKeybordAppears:(NSNotification*)aNotification{
NSDictionary* userInfo = [aNotification userInfo];
NSTimeInterval animationDuration;
UIViewAnimationCurve animationCurve;
CGRect keyboardFrame;
[[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] getValue:&animationCurve];
[[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] getValue:&animationDuration];
[[userInfo objectForKey:UIKeyboardFrameEndUserInfoKey] getValue:&keyboardFrame];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:animationDuration];
[UIView setAnimationCurve:animationCurve];

[self.view setFrame:CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y - keyboardFrame.size.height, self.view.frame.size.width, self.view.frame.size.height)];

[UIView commitAnimations];
}

我是初学者，所以请不要打败我，但我不知道移动和显示工具栏及其文本字段的缺失链接。

工具栏和文本字段在该viewDidLoad方法中创建。

我发现 ToolBar 本身必须随键盘移动：这可以防止它被出现的键盘隐藏：

在此处输入图像描述

在 NavigationController 中使用 ToolBar 时，以下代码应该可以解决问题：

- (void) liftMainViewWhenKeybordAppears:(NSNotification*)aNotification
{
NSDictionary* userInfo = [aNotification userInfo];
NSTimeInterval animationDuration;
UIViewAnimationCurve animationCurve;
CGRect keyboardFrame;

[[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] getValue:&animationCurve];
[[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] getValue:&animationDuration];
[[userInfo objectForKey:UIKeyboardFrameBeginUserInfoKey] getValue:&keyboardFrame];


[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:animationDuration];
[UIView setAnimationCurve:animationCurve];    

[self.navigationController.toolbar setFrame:CGRectMake(self.navigationController.toolbar.frame.origin.x,
                                                       self.navigationController.toolbar.frame.origin.y - keyboardFrame.size.height +self.navigationController.toolbar.frame.size.height,
                                                       self.navigationController.toolbar.frame.size.width,
                                                       self.navigationController.toolbar.frame.size.height)];
[UIView commitAnimations];

}

所有其他必要的代码都在这里很好地描述了。

self.view 不包含工具栏，您必须单独移动工具栏...
