I have a EKEventEditViewController
that I initializie and present like this:
EKEventEditViewController *addController = [[[EKEventEditViewController alloc] initWithNibName: nil bundle: nil] autorelease];
[self presentModalViewController: addController animated: NO];
I notice that on an iPhone 5 with iOS 6.1.3 it takes about 3 seconds until the modalView shows up.
Make sure to call that from the main tread
