Dismiss function public

[phillebaba]

It would be great if we could make the dismiss function public to that the viewcontroller can be removed through custom logic. An option would be to access the done button method.

- (void)doneButtonTapped:(id)sender {
    self.transitionController.forcesNonInteractiveDismissal = YES;
    [self setOverlayViewHidden:YES animated:NO];
    [self dismissAnimated:YES];
}

Having dismiss function public, with an animation completion block would be very useful. I've hacked together a solution where we pull the dismiss method from the dismiss button, but that's clearly not the best solution.

For uses who are not familiar with the swipe-up/down-to-dismiss-gesture it's a little confusing.
I watched two of my friends who haven't used this before and they both didn't know what to do for seconds. It would be better to add a close bar button item at the upper-left corner. Just like a close button in a normal modal view controller which people know for a long time.

I agree with @phillebaba and @livings124 .Want dismissAnimated: too.

Currently I'm using swift code photoViewer.performSelector(Selector("dismissAnimated:"), withObject: true) but no animation.

There is supposed to be one but it's broken on develop right now; see issue #102 .

Re: this proposal and the PR #96 , I've been holding off exposing dismissAnimated: because we believe the correct approach is to make the standard UIViewController method -dismissViewControllerAnimated:completion: work properly. Clearly it doesn't right now, but we believe it should; introducing a view controller which requires calling a custom method for dismissal feels wrong & breaks inheritance.

I haven't had time to dig into this to see what's required to make this work, but I would prefer making -dismissViewControllerAnimated:completion: work properly before we consider exposing the existing internal -dismissAnimated: method.
