如何让 UIView 从 UINavigationBar 下滑出？

目前，我正在显示一个 UIView，它从窗口顶部向下滑动到一个位置：

-(void)showNotificationBar
{
    [notificationBar setFrame: CGRectMake(0, 0, 320, 44)];
    [[[UIApplication sharedApplication] keyWindow] addSubview:notificationBar];

    [UIView animateWithDuration:0.5
                          delay:0.0
                        options: UIViewAnimationCurveEaseInOut
                     animations:^{
                         [notificationBar setFrame: CGRectMake(0, 59, 320, 32)];
                     } 
                     completion:^(BOOL finished){
                         NSLog(@"Done!");
                     }];
}

我希望它从 UINavigationBar 下方滑出。现在它从窗口顶部滑动到导航栏的底部。我希望它从导航栏底部滑动以显示自身。现在确切知道该怎么做吗？

Currently I am displaying a UIView that slides down from the top of my window to a position:

-(void)showNotificationBar
{
    [notificationBar setFrame: CGRectMake(0, 0, 320, 44)];
    [[[UIApplication sharedApplication] keyWindow] addSubview:notificationBar];

    [UIView animateWithDuration:0.5
                          delay:0.0
                        options: UIViewAnimationCurveEaseInOut
                     animations:^{
                         [notificationBar setFrame: CGRectMake(0, 59, 320, 32)];
                     } 
                     completion:^(BOOL finished){
                         NSLog(@"Done!");
                     }];
}

I want this to slide out from under my UINavigationBar. Right now it is sliding from the top of the window, to the bottom of my navigation bar. I want it to slide from the bottom of the navigation bar to display itself. Now exactly sure how to do this?

您将在窗口中所有其他视图的顶部添加 notificationBar。您需要将其添加为导航栏超级视图的子视图，位于导航栏下方。

假设您的 UINavigationBar 位于属性 self.navBar 中。试试这个：

- (void)showNotificationBar
{
    CGRect frame = CGRectMake(0, 0, 320, 44);
    frame.origin.y = CGRectGetMaxY(self.navBar.frame) - frame.size.height;
    notificationBar.frame = frame;

    [self.navBar.superview insertSubview:notificationBar belowSubview:self.navBar];

    [UIView animateWithDuration:0.5 animations:^{
        CGRect frame = notificationBar.frame;
        frame.origin.y = CGRectGetMaxY(self.navBar.frame);
        notificationBar.frame = frame;
    }];
}

You're adding notificationBar on top of all other views in your window. You need to add it as a subview of the nav bar's superview, below the nav bar.

Let's say your UINavigationBar is in a property self.navBar. Try this:

- (void)showNotificationBar
{
    CGRect frame = CGRectMake(0, 0, 320, 44);
    frame.origin.y = CGRectGetMaxY(self.navBar.frame) - frame.size.height;
    notificationBar.frame = frame;

    [self.navBar.superview insertSubview:notificationBar belowSubview:self.navBar];

    [UIView animateWithDuration:0.5 animations:^{
        CGRect frame = notificationBar.frame;
        frame.origin.y = CGRectGetMaxY(self.navBar.frame);
        notificationBar.frame = frame;
    }];
}
