Is it possible to determine whether ViewController is presented as Modal?

Question

Is it possible to check inside ViewController class that it is presented as modal view controller?

Answer 1

What worked for me is following:

// this is the trick: set parent view controller as application's window root view controller
UIApplication.sharedApplication.delegate.window.rootViewController = viewController;

// assert no modal view is presented
XCTAssertNil(viewController.presentedViewController);

// simulate button tap which shows modal view controller
[viewController.deleteButton sendActionsForControlEvents:UIControlEventTouchUpInside];

// assert that modal view controller is presented
XCTAssertEqualObjects(viewController.presentedViewController.class, MyModalViewController.class);

As far as I tested it, this works for iOS7 and iOS8. Didn't try on iOS6 however.
