Dismiss SVProgressHUD with Tap Gesture
<p>I need to add a UITapGestureRecognizer to the <a href="https://github.com/SVProgressHUD/SVProgressHUD" rel="nofollow">SVProgressHUD</a>. The SVProgressHUD already has the ability to dismiss using <code>-(void) dismiss;</code>. The code for this will dismiss the animation based on seconds. </p>

<pre><code>- (void)dismiss {
for (UIGestureRecognizer *gesture in [[[self class] sharedView] gestureRecognizers]) {
    [[[self class] sharedView] removeGestureRecognizer:gesture];
}

NSDictionary *userInfo = [self notificationUserInfo];
[[NSNotificationCenter defaultCenter] postNotificationName:SVProgressHUDWillDisappearNotification
                                                    object:nil
                                                  userInfo:userInfo];

self.activityCount = 0;
[UIView animateWithDuration:0.15
                      delay:0
                    options:UIViewAnimationCurveEaseIn | UIViewAnimationOptionAllowUserInteraction
                 animations:^{
                     self.hudView.transform = CGAffineTransformScale(self.hudView.transform, 0.8, 0.8);
                     if(self.isClear) // handle iOS 7 UIToolbar not answer well to hierarchy opacity change
                         self.hudView.alpha = 0;
                     else
                         self.alpha = 0;
                 }
                 completion:^(BOOL finished){
                     if(self.alpha == 0 || self.hudView.alpha == 0) {
                         self.alpha = 0;
                         self.hudView.alpha = 0;

                         [[NSNotificationCenter defaultCenter] removeObserver:self];
                         [self cancelRingLayerAnimation];
                         [self addTapGestureToDismiss];
                         [_hudView removeFromSuperview];
                         _hudView = nil;

                         [_overlayView removeFromSuperview];
                         _overlayView = nil;

                         [_indefiniteAnimatedView removeFromSuperview];
                         _indefiniteAnimatedView = nil;


                         UIAccessibilityPostNotification(UIAccessibilityScreenChangedNotification, nil);

                         [[NSNotificationCenter defaultCenter] postNotificationName:SVProgressHUDDidDisappearNotification
                                                                             object:nil
                                                                           userInfo:userInfo];

                         // Tell the rootViewController to update the StatusBar appearance
                         UIViewController *rootController = [[UIApplication sharedApplication] keyWindow].rootViewController;
                         if ([rootController respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]) {
                             [rootController setNeedsStatusBarAppearanceUpdate];
                         }
                         // uncomment to make sure UIWindow is gone from app.windows
                         //NSLog(@"%@", [UIApplication sharedApplication].windows);
                         //NSLog(@"keyWindow = %@", [UIApplication sharedApplication].keyWindow);
                     }
                 }];
</code></pre>

<p>My thought process is to add the tapGesture code to the dismiss method. This is what I have written so far. </p>

<pre><code>- (void)addTapGestureToDismiss {

// Creation and initializer of the tap gesture
UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc]
                                         initWithTarget:self action:@selector(dismiss)];

// Specify that the gesture must be a single tap
tapRecognizer.numberOfTapsRequired = 1;

// Add the tap gesture recognizer to the view
[[[self class] sharedView] addGestureRecognizer:tapRecognizer];
</code></pre>

<p>}</p>

<p>As you can see I'm just initializing the tapGesture. I've run into the issue of placing it in a few places and causing the app to only have one single tap. I've pretty much confused myself in the process. Should I</p>

<ul>
<li>add this gesture to the view?</li>
<li>add this gesture to dismiss?</li>
</ul>
