iphone - 出现键盘时移动UIView

Question

我对我的英语感到抱歉。

我试图找到它之前行事。但是问题在于，ViewController在景观中创建了UIView一半的ViewController。在UIView中有UITextView。但是现在，当键盘出现在ViewController中时，背景会在键盘下方向下滚动。并且仅查看UIView。如果触摸空间，键盘将消失并且背景恢复。我只想在键盘出现时移动UIView。

非常感谢你。

尝试这个

- (void)viewDidAppear:(BOOL)animated
{
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];
}

- (void)keyboardWillShow:(NSNotification *)note
{
    CGRect keyboardBounds;
    NSValue *aValue = [note.userInfo objectForKey:UIKeyboardFrameBeginUserInfoKey];

    [aValue getValue:&keyboardBounds];
    keyboardHeight = keyboardBounds.size.height;
    if (!keyboardIsShowing)
    {
        keyboardIsShowing = YES;
        CGRect frame = view.frame;
        frame.size.height -= 168;

        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationBeginsFromCurrentState:YES];
        [UIView setAnimationDuration:0.3f];
        view.frame = frame;
        [UIView commitAnimations];
    }
}

- (void)keyboardWillHide:(NSNotification *)note
{
    CGRect keyboardBounds;
    NSValue *aValue = [note.userInfo valueForKey:UIKeyboardFrameEndUserInfoKey];
    [aValue getValue: &keyboardBounds];

    keyboardHeight = keyboardBounds.size.height;
    if (keyboardIsShowing)
    {
        keyboardIsShowing = NO;
        CGRect frame = view.frame;
        frame.size.height += 168;

        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationBeginsFromCurrentState:YES];
        [UIView setAnimationDuration:0.3f];
        view.frame = frame;
        [UIView commitAnimations];

    }
}
