Is it possible to use UIActivityIndicator in launch screen with Xcode6

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.

You can't able to code animations on Launch screen...if you want to do any animations on launch screen...use your first view controller as splash view...
