ios - 使用动画隐藏 Navigation Controller 和 Tab Bar Controller

Question

我试图在触摸按钮时同时隐藏 UITabBarController 和 UINavigationController。我在这里找到了一个非常好的代码片段 How to hide uitabbarcontroller但是我在尝试隐藏 UINavigationController 和 tabbarcontroller 并为其设置动画时遇到了问题。当他们使用 self.tabBarController.tabBar.hidden = YES 隐藏标签栏时，我还在互联网上发现了很多示例，但这只隐藏了按钮项而不是底部的黑条。

玩了很多次之后，我可以正确地制作两个动画，因为我认为这与导航 Controller 的隐藏有关，这使得整个窗口的大小可以动态改变。

-(IBAction)touchImage:(id)sender {

    if (isImageFullScreen) {

        isImageFullScreen = NO;

        [self.navigationController setNavigationBarHidden:NO animated:YES];
        [UIView transitionWithView:self.view
                          duration:0.5
                           options:UIViewAnimationOptionCurveLinear
                        animations:^
         {
             hotelImageButton.frame = CGRectMake(0,20,320,92);
             [self showTabBar:self.tabBarController];
         }
                        completion:^(BOOL finished)
         {
         }];

    } else {

        isImageFullScreen = YES;

        [self.navigationController setNavigationBarHidden:YES animated:YES];
        [UIView transitionWithView:self.view
                          duration:0.5
                           options:UIViewAnimationOptionCurveLinear
                        animations:^
         {
             hotelImageButton.frame = CGRectMake(0,0,320,480);
             [self hideTabBar:self.tabBarController];
         }
                        completion:^(BOOL finished)
         {                                  
         }];
    }

hideTabBar 和 showTabBar 方法来 self 上面链接的另一篇文章。

我也尝试了一些其他的组合，但我不能让它看起来很好。有什么想法吗？

提前致谢。

我现在尝试了该代码，发现 UITabBar 显示动画没有顺利进行。我通过将显示动画的标签栏的持续时间调整得更短，设法让它更流畅。

[UIView setAnimationDuration:0.2];

希望这能奏效。

编辑:请尝试此代码，它在 1 个动画事务中将父 View 的大小调整为更大，以便仅隐藏条形图并显示内容。

- (IBAction)TestButton1:(UIButton *)sender {

if(!isAnimating){
    if(isTabBarAndNavBarHidden){

        [UIView transitionWithView:self.view
                          duration:0.5
                           options:UIViewAnimationOptionTransitionNone
                        animations:^
         {
             isAnimating=YES;

             CGFloat statusBar_height=[[UIApplication sharedApplication] statusBarFrame].size.height;
             CGFloat screen_height=[UIScreen mainScreen].bounds.size.height;

             [self.tabBarController.view setFrame:CGRectMake(self.tabBarController.view.frame.origin.x, 0, self.tabBarController.view.frame.size.width, screen_height)];
             [self.navigationController.navigationBar setFrame:CGRectMake(self.navigationController.navigationBar.frame.origin.x, statusBar_height, self.navigationController.navigationBar.frame.size.width, self.navigationController.navigationBar.frame.size.height)];
         }
                        completion:^(BOOL finished)
         {
             isTabBarAndNavBarHidden=NO;
             isAnimating=NO;
         }];

    }else{

        [UIView transitionWithView:self.view
                          duration:0.5
                           options:UIViewAnimationOptionTransitionNone
                        animations:^
         {
             isAnimating=YES;

             CGFloat statusBar_height=[[UIApplication sharedApplication] statusBarFrame].size.height;
             CGFloat screen_height=[UIScreen mainScreen].bounds.size.height;

             [self.tabBarController.view setFrame:CGRectMake(self.tabBarController.view.frame.origin.x, statusBar_height-self.navigationController.navigationBar.frame.size.height, self.tabBarController.view.frame.size.width, screen_height+self.navigationController.navigationBar.frame.size.height+self.tabBarController.tabBar.frame.size.height-statusBar_height)];
             [self.navigationController.navigationBar setFrame:CGRectMake(self.navigationController.navigationBar.frame.origin.x, 0, self.navigationController.navigationBar.frame.size.width, self.navigationController.navigationBar.frame.size.height)];


         }
                        completion:^(BOOL finished)
         {
             isTabBarAndNavBarHidden=YES;
             isAnimating=NO;
         }];

    }
