self.zoomScale == self.maximumDoubleTapZoomScale, this case never happens

[Kieu Quang Loc]

Hi @thiagoperes , when I use IDMPhotoBrowser a high quality image, I get a problem with double tap to zoom out and zoom in, please help!

- (void)handleDoubleTap:(CGPoint)touchPoint {
	
	// Cancel any single tap handling
	[NSObject cancelPreviousPerformRequestsWithTarget:_photoBrowser];
	
	// Zoom
	if (self.zoomScale == self.maximumDoubleTapZoomScale) {
		
		// Zoom out
		[self setZoomScale:self.minimumZoomScale animated:YES];
		
	} else {
		
		// Zoom in
		CGSize targetSize = CGSizeMake(self.frame.size.width / self.maximumDoubleTapZoomScale, self.frame.size.height / self.maximumDoubleTapZoomScale);
		CGPoint targetPoint = CGPointMake(touchPoint.x - targetSize.width / 2, touchPoint.y - targetSize.height / 2);
		
		[self zoomToRect:CGRectMake(targetPoint.x, targetPoint.y, targetSize.width, targetSize.height) animated:YES];
		
	}
	
	// Delay controls
	[_photoBrowser hideControlsAfterDelay];
}
