Switch off **`Multitasking Gestures`**. This can be done in the **Settings panel**.

`iOS 7` adds support for `gestures` which allow you to control audio or consult the calendar. You do not need to add `gesture recognizers` of your own; the OS brings them in all by itself. They also cannot be disabled from within the app.

Now for what I suspect is the reason for the messages: It seems your cat is sending so many touch events to the touch recognizer that it is overloaded. This is in essence what the error message means. It could not process all touch events in a timely manner. After all, a cat has four paws ...

I have an app with an app with a `UIScrollView`. I am letting IOS handle all the I/O (i.e., no **`gesture recognizers`**).

I have a cat that likes playing on the `iPad` and she is able to manipulate the `scrollview` in such a way that it gets the error in the title.

I have seen this mentioned in other posts where there were `PinchGestureRecognizer`. 

What would be causing this in the absence of one?
What does it mean?

I don&#39;t know what the cat does to cause this. She can do it nearly on demand. I can&#39;t do it at all.

I need to download and install an `ipa` directly from an URL.

I have tried this:

    NSURL *url = [NSURL URLWithString:@&quot;https://myWeb.com/test.ipa&quot;];
    [[UIApplication sharedApplication] openURL:url];

The app launches Safari but then this message appears:

![Error Message &quot;Download Failed, Safari cannot download this file.&quot;][1]

Is it possible?

I am trying to make the status bar for one of my view controllers to be hidden (when displayed modally). When I&#39;m presenting the view controller, the status bar is is to be hidden and then returned when dismissed.

I have added the following code to the presented view controller

    - (BOOL)prefersStatusBarHidden
    {
        return YES;
    }

I have also set the keys in the Info.plist file to the following:

    &lt;key&gt;UIViewControllerBasedStatusBarAppearance&lt;/key&gt;
    &lt;true/&gt;

From my understanding this should be all that is required to make this work. 

I am also using a custom Animation Controller to do the presenting which conforms to the `UIViewControllerAnimatedTransitioning` protocol. In the `animateTransition:` implementation I have tried to manually call `prefersStatusBarHidden`, followed by `setNeedsStatusBarAppearanceUpdate` to ensure the call is being made, but the status bar remains.

Any ideas why this is happening would be appreciated. I have searched StackOverflow, but it appears no one has had this issue, all accepted answers refer to calling `setNeedsStatusBarAppearanceUpdate`, which I am already doing.

**EDIT** - The code below now seems to ***WORK*** as desired 

    - (void)animateTransition:(id &lt;UIViewControllerContextTransitioning&gt;)transitionContext
    {
        if (self.isPresenting) {
            UIView *containerView = [transitionContext containerView];
    
            UIViewController *fromViewController = [transitionContext viewControllerForKey:UITransitionContextFromViewControllerKey];
            UIViewController *toViewController = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey];
    
            toViewController.view.frame = containerView.frame;
    
            [containerView addSubview:toViewController.view];

            // Ask the presented controller whether to display the status bar
            [toViewController setNeedsStatusBarAppearanceUpdate];
    
            [UIView animateWithDuration:1.0f delay:0.0f options:UIViewAnimationOptionCurveEaseIn animations:^{
                toViewController.view.alpha = 1.0f;
                fromViewController.view.alpha = 0.0f;
            } completion:^(BOOL finished) {
                [transitionContext completeTransition:YES];
            }];
        }
        else {
            // do the reverse
            UIViewController *fromViewController = [transitionContext viewControllerForKey:UITransitionContextFromViewControllerKey];
            UIViewController *toViewController = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey];
    
            [UIView animateWithDuration:1.0f delay:0.0f options:UIViewAnimationOptionCurveEaseIn animations:^{
                toViewController.view.alpha = 1.0f;
                fromViewController.view.alpha = 0.0f;
            } completion:^(BOOL finished) {
                [transitionContext completeTransition:YES];
                // Once dismissed - ask the presenting controller if the status bar should be presented
                [toViewController setNeedsStatusBarAppearanceUpdate];
            }];
        }
    }

    ....

    // PresentingController.m
    - (BOOL)prefersStatusBarHidden
    {
        if (self.presentedViewController) {
            return YES;
        }
        return NO;
    }

    // PresentedController.m
    - (BOOL)prefersStatusBarHidden
    {
        return YES;
    }


UIViewController&#39;s prefersStatusBarHidden not working

How can I, in my view controller code, differentiate between:

 * presented modally
 * pushed on navigation stack

Both `presentingViewController` and `isMovingToParentViewController` are `YES` in both cases, so are not very helpful.

What complicates things is that my parent view controller is sometimes modal, on which the to be checked view controller is pushed.

It turns out my issue is that I embed my `HtmlViewController` in a `UINavigationController` which is then presented. That&#39;s why my own attempts and the good answers below were not working.

    HtmlViewController*     termsViewController = [[HtmlViewController alloc] initWithDictionary:dictionary];
    UINavigationController* modalViewController;

    modalViewController = [[UINavigationController alloc] initWithRootViewController:termsViewController];
    modalViewController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
    [self presentViewController:modalViewController
                       animated:YES
                     completion:nil];

I guess I&#39;d better tell my view controller when it&#39;s modal, instead of trying to determine.
