Question

I’ve got a method that is in my app delegate that is called to pull information from a web server. Is there a way to easily incorporate UIActivityViewIndicators into the app delegate? Everything I’ve found so far online shows the Indicator requiring to be added as a subview. Is this doable? If so, can you point me in the right direction on where to find this?

[edit]
I’m using a storyboard instead of xibs.

You can easily add a UIActivityViewIndicators with few lines of code:

UIActivityIndicatorView *aiv = [[[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite] autorelease];  
aiv.center = self.window.rootViewController.view.center;
[self.window.rootViewController.view addSubview:aiv];
[aiv startAnimating]; 

But there are a lot of open source project like MBProgressHUD that gives you more stylish indicator, with other additions..
