Options appear when tap on UIImageView

Question

In Apple iOs photos app, Each picture take the full screen, but when You tap on it, navigation bar and tab bar with some menu options (like share picture) just appear and remain for a couple of secconds. How can I do that in my UIImageView ?

Answer 1

Add a UITapGestureRecognizer to your view and UiView for your topbar and bottom bar or what else you like and follow below code. I think This may help you.

//Write below code in ViewDidLoad

UITapGestureRecognizer *singleTapOne = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
    singleTapOne.numberOfTouchesRequired = 1; singleTapOne.numberOfTapsRequired = 1; singleTapOne.delegate = self;


    [self.view addGestureRecognizer:singleTapOne]; [singleTapOne release];
    for (UIGestureRecognizer *gR in self.view.gestureRecognizers) {
        gR.delegate = self;

// handleSingleTap Method

- (void)handleSingleTap:(UITapGestureRecognizer *)recognizer
{




    if (recognizer.state == UIGestureRecognizerStateRecognized)
    {
        CGRect viewRect = recognizer.view.bounds; // View bounds

        CGPoint point = [recognizer locationInView:recognizer.view];

        CGRect areaRect = CGRectInset(viewRect, TAP_AREA_SIZE, 0.0f); // Area

        if (CGRectContainsPoint(areaRect, point)) // Single tap is inside the area
        {


            if ((m_CtrlViewTopBar.hidden == YES) || (m_CtrlViewBottomBar.hidden == YES))
            {
                [self showToolbar:m_CtrlViewTopBar];
                [self showToolbar:m_CtrlViewBottomBar]; // Show
            }
            else
            {
                [self hideToolbar:m_CtrlViewTopBar];
                [self hideToolbar:m_CtrlViewBottomBar];
            }


            return;
        }

        CGRect nextPageRect = viewRect;
        nextPageRect.size.width = TAP_AREA_SIZE;
        nextPageRect.origin.x = (viewRect.size.width - TAP_AREA_SIZE);

        if (CGRectContainsPoint(nextPageRect, point)) // page++ area
        {
            //[self incrementPageNumber]; return;
        }

        CGRect prevPageRect = viewRect;
        prevPageRect.size.width = TAP_AREA_SIZE;

        if (CGRectContainsPoint(prevPageRect, point)) // page-- area
        {
            //[self decrementPageNumber]; return;
        }
    }

}
