I’m trying to create a menu (using UIScrollView) where the user can select images

  • 0

I’m trying to create a menu (using UIScrollView) where the user can select images (using UIImageViews).

I intend to have at least 3 images visible at anytime. When I scroll, the images will be able to snap into position.

However, if I am to use a UIScrollView which is large enough to display 3 images at anyone time, and I enable paging, the paging will move all 3 images together and snap only at the next 3 images.

And if I am to use UIScrollView that fits just 1 image, and I enable clipsToBounds (which helps me draw the images beyond the boundary of the UIScrollView). My figure gestures can only be detected within UIScrollView itself, I want my figure gestures to be detected as long as any of the images are touched.

Thanks.

    You can use following method of UIScrollView to scroll it from code as much as you want.


    - (void)scrollRectToVisible:(CGRect)rect animated:(BOOL)animated

    you can call this from following method of UIScrowViewDelegate.

    - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView

    Thus, you can manage how much you scroll view will call.

    And for getting touches, implement a separate class that display images(inherit it from UIImageView or UIView) and implement touchesBegin or touchesEnded in that. Here when you get the touch in your custom view call some method of parent view and notify it with proper arguments(you can assign tag property and pass it to scroll view to find exactly which image was tapped).

    …..I am not sure weather I am solving your problem or not…..so post here if you need any further assistance.
