Retrieving an object tag from a UITapGestureRecognizer

Question

I have a UIScrollViewone used inside a custom class that has subclasses UIView. Inside this scrollview, I added several other custom objects (all subclasses UIView):) /

UITapGestureRecognizer *tap;

    for (int count = 0; count < ColorSchemeCount; count++) {
        //Check for next page first
        [self managePageAdditions];

        //Set up the scheme
        ColorScheme *scheme = [[ColorScheme alloc]
                               initWithFrame:[self determineSchemeCircleFrameFromCount:pageCheck]
                               title:[self getColorSchemeTitleFromIndex:pageCheck]
                               colors:[self getColorSchemeFromIndex:pageCheck]];
        scheme.tag = pageCheck;
        tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(schemeTouchedAtIndex:)];
        tap.cancelsTouchesInView = NO;
        [scheme addGestureRecognizer:tap];
        [self.scrollView addSubview:scheme];

        //See if next pass requires a new page or not
        if(pageCheck > 0) needsNextPage = (pageCheck % kSchemesPerPage == 0);
        needsNextPage ? pageCheck = 0 : pageCheck++;
    }

And then I try to see the tag ColorSchemeto respond accordingly:

- (void)schemeTouchedAtIndex:(UITapGestureRecognizer *)gesture{
    CGPoint touchPointInSuperview = [gesture locationInView:self.scrollView];
    ColorScheme *touchedView = (ColorScheme *)[self.scrollView hitTest:touchPointInSuperview withEvent:nil];

    NSLog(@"%li", (long)touchedView.tag);
}

And no matter what I do, it always registers the tag as zero .

A few observations:

• I can confirm that the tags are set correctly and everything is ColorSchemeadded just fine.
• I also have it tap.cancelsTouchesInView = NO, so it UIScrollViewwon’t swallow all the touches.
• locationInView self self.scrollView, . , , , UIView.

Answer 1

-(void)schemeTouchedAtIndex:(UITapGestureRecognizer *)gesture{
NSLog(@"%ld", gesture.view.tag);
}

ColorScheme, , .
