Animating Activity Indicator on iOS launch screen

Question

Is it possible to use UIActivityIndicator on the iOS launch screen?

I tried, but it's not animating.

Has anyone tried this or know whether it's possible?

I added UIActivityIndicator in Xib file and checked its animating property — Zoeb S, Dec 17 '14 at 05:58
You have to set property `startAnimating`. Or in Storyboard check mark `behaviour = Animating`. — Kampai, Dec 17 '14 at 06:02
I did @Kampai Its working on other screen but not on launch screen — Zoeb S, Dec 17 '14 at 06:35
@cyberlobe have you tried UIActivityIndicator on launch screen? — Zoeb S, Dec 17 '14 at 06:37
What I guess is launch screen takes very short time to load, I think launch screen complete its execution before activity view is start animating. — Kampai, Dec 17 '14 at 06:39

What you are trying to achieve is to show ActivityIndicator during launch screen which is not possible, but you can achieve it by some different way.

Here is the idea that may help you:

Create separate loading page & call it from didFinishLaunchingWithOptions method in App delegate
Add Splash image & indicator to it
You can set timer of 2-3 seconds than redirect to your first page of app

While using indicator make sure you have checked StartAnimating to true or simply add indicator programmatically like this:

UIActivityIndicatorView *activity = [[UIActivityIndicatorView alloc]  initWithFrame:CGRectMake(225, 115, 30, 30)];

[activity setBackgroundColor:[UIColor clearColor]]; 

[activity setActivityIndicatorViewStyle: UIActivityIndicatorViewStyleGray];

[self.view addSubview: activity];

[activity startAnimating];

Hope it will work for you.

That's what I would do – Debanjan Chakraborty Dec 17 '14 at 06:50
Pay attention that the launch image is on full screen and if you use for example navigation controller, you might have issues with it. – OhadM Aug 12 '15 at 10:51
I like doing this method, especially when the initial screen changes from launch to launch – StaRbUck42 Jul 18 '17 at 14:49

You can't use animations on the Launch Screen.

If you want to do any animations on the "launch screen", instead use your first view controller as a splash view.

Go to storyboard then select your ActivityIndicator and change the property to "Animating"

You did not check this solution. And it is not working also technically speaking, because as stated above at the launchscreen your app is not yet running, so Launch Screen is more of a static image the system puts while preparing your app to run. – Fawkes Oct 06 '15 at 20:32
