UIKeyBoard调整方向更改为横向

Question

这是一个非常新秀的问题.我在底部有一个UIToolBar,当显示UIKeyBoard时,它应该用键盘上下动画.我在UIKeyBoard Notifications的帮助下完成了这项工作.我们正在讨论的视图已启用拆分视图.当设备方向是横向时,两个视图都显示为[希望有意义].

当显示键盘时,我这样做

CGSize keyBoardSize = [[notificationInfo objectForKey:UIKeyboardFrameEndUserInfoKey]CGRectValue].size;

CGRect toolbarFrame= [BottomToolBar frame];
toolbarFrame.origin.y -= keyBoardSize.height;    
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.3];
BottomToolBar .frame = viewFrame;
[UIView commitAnimations];

当键盘是hiiden我这样做

toolbarFrame.origin.y += keyBoardSize.height;

我的问题是当设备方向改变为横向时,当键盘可见时,底部工具栏消失.我看到它快速上升.我不知道如何解决这个问题.有人可以帮忙吗？另外,有没有办法不让键盘跨越分割视图中的两个视图？

Answer 1

我也有这个问题,所有我能想到的是解雇键盘并重新显示它(辞职然后再次成为第一响应者).但这似乎非常令人不满意.

另请注意,您应该将rect从屏幕坐标转换为视图的坐标.(屏幕坐标不旋转.)

CGRect keyboardRect = [[notificationInfo objectForKey:UIKeyboardFrameEndUserInfoKey]CGRectValue];
keyboardRect = [[BottomToolBar superview] convertRect:keyboardRect fromView:nil];

更新:您必须注册UIKeyboardWillShowNotification,然后在界面旋转时调用您的操作:)

- (void)viewDidLoad {
    [super viewDidLoad];

    [[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 *)aNotification 
{
    CGRect keyboardBounds;
    [[aNotification.userInfo valueForKey:UIKeyboardFrameEndUserInfoKey] getValue: &keyboardBounds];

    CGFloat keyboardHeight;
    switch ([UIApplication sharedApplication].statusBarOrientation) {
        case UIInterfaceOrientationPortrait:
        case UIInterfaceOrientationPortraitUpsideDown:
            keyboardHeight = keyboardBounds.size.height;
            break;
        case UIInterfaceOrientationLandscapeLeft:
        case UIInterfaceOrientationLandscapeRight:
            keyboardHeight = keyboardBounds.size.width;
            break;
    }

    NSTimeInterval animationDuration = [[[aNotification userInfo] objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];

    CGRect rect = table.frame;
    rect.size.height -= keyboardHeight;
    [UIView beginAnimations:@"ResizeForKeyboardShow" context:nil];
    [UIView setAnimationDuration:animationDuration];
    table.frame = rect;
    [UIView commitAnimations];
}

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

    CGFloat keyboardHeight;
    switch ([UIApplication sharedApplication].statusBarOrientation) {
        case UIInterfaceOrientationPortrait:
        case UIInterfaceOrientationPortraitUpsideDown:
            keyboardHeight = keyboardBounds.size.height;
            break;
        case UIInterfaceOrientationLandscapeLeft:
        case UIInterfaceOrientationLandscapeRight:
            keyboardHeight = keyboardBounds.size.width;
            break;
    }

    NSTimeInterval animationDuration = [[[aNotification userInfo] objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue];

    CGRect rectTable = table.frame;
    rectTable.size.height += keyboardHeight;
    [UIView beginAnimations:@"ResizeForKeyboard" context:nil];
    [UIView setAnimationDuration:animationDuration];
    table.frame = rectTable;
    [UIView commitAnimations];
}
