使用动画隐藏导航控制器和标签栏控制器

Question

我正在尝试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如何隐藏uitabbarcontroller但是在尝试隐藏和动画UINavigationController和tabbarcontroller时我遇到了问题.我在互联网上发现了很多例子,当他们隐藏tabbar使用self.tabBarController.tabBar.hidden = YES但只隐藏按钮项而不是底部的黑条.

在玩了很多之后,我可以正确制作动画,因为我认为它与导航控制器的隐藏有关,这使得整个窗口的大小可以随时改变.

-(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方法是我上面链接的其他帖子中的方法.

我也试过其他一些组合,但我不能让它看起来不错.有任何想法吗？

提前致谢.

Answer 1

我现在尝试了这个代码,我发现UITabBar节目动画不能顺利进行.我设法通过调整显示动画的标签栏的持续时间来使其更平滑.

[UIView setAnimationDuration:0.2];

希望这有效.

编辑:请尝试此代码,它调整父视图的大小在1动画事务中更大,只有隐藏条和显示内容.

- (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;
         }];

    }
}
