可以滑下UITabBarController吗？

Question

I'm sure I've seen code for this somewhere this somewhere, but I can't find it...

I'd like to be able to programatically slide down a UITabBarController... not when transitioning to another view, but within the same view.

Answer 1

If you want to slide the UITabBar down and up you can try something like:

- (IBAction)showHideTabBar:(id)sender {
    static BOOL isShowing = YES;

    CGRect tabBarFrame = self.tabBarController.tabBar.frame;

    if (isShowing) {
        tabBarFrame.origin.y += tabBarFrame.size.height;
    }
    else {
        tabBarFrame.origin.y -= tabBarFrame.size.height;
    }

    isShowing = !isShowing;

    [UIView animateWithDuration:0.3 animations:^ {
        [self.tabBarController.tabBar setFrame:tabBarFrame];
    }];
}
