iOS-如何使用动画隐藏/显示UITabBarController的标签栏？ [英] iOS- How to Hide/Show UITabBarController's tab bar with animation?

问题描述

我对iOS的 UITabBarController 的标签栏有疑问。

I have a question about iOS's UITabBarController's tab bar.

我正在使用 UITabBarController 显示一些视图，但我希望视图以尽可能大的屏幕显示。是否可以隐藏标签栏以使其通常不显示，直到用户触摸屏幕，然后标签栏将（带动画）显示在底部。然后，几秒钟后，如果什么也没做，那么标签栏会再次消失，以便视图再次回到全屏？

I'm using a UITabBarController to display a few views, but as I want the views to be displayed with as large a screen as possible. Is it possible to hide the tab bar so that it normally doesn't show, until the user touches the screen, then the tab bar will (with animation) show up at the bottom. Then, after a few seconds, if nothing is done, then the tab bar will again go away, so that the view going back to be full screen again?

推荐答案

这就是你展示它的方式

- (void)showTabBar:(UITabBarController *)tabbarcontroller
{
    tabbarcontroller.tabBar.hidden = NO;
    [UIView animateWithDuration:kAnimationInterval animations:^{
        for (UIView *view in tabbarcontroller.view.subviews) {
            if ([view isKindOfClass:[UITabBar class]]) {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y-49.f, view.frame.size.width, view.frame.size.height)];
            }
            else {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, view.frame.size.height-49.f)];
            }
        }
    } completion:^(BOOL finished) {
        //do smth after animation finishes
    }];
}

...这就是你隐藏它的方式

... and this is how you hide it

- (void)hideTabBar:(UITabBarController *)tabbarcontroller
{
    [UIView animateWithDuration:kAnimationInterval animations:^{
        for (UIView *view in tabbarcontroller.view.subviews) {
            if ([view isKindOfClass:[UITabBar class]]) {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y+49.f, view.frame.size.width, view.frame.size.height)];
            }
            else {
                [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, view.frame.size.height+49.f)];
            }
        }
    } completion:^(BOOL finished) {
        //do smth after animation finishes
        tabbarcontroller.tabBar.hidden = YES;
    }];
}
