UIScrollView does not work with EXC_BAD_ACCESS

I have a scrollview that is subview of view, and has the subviews. The problem is this: the scrollView came with the black background (as I have set transparent) and also does not work. The scrollView is connected with an IBOutlet. I redid the XIB 2 times, what needs fixing? When I add the scrollView as subview of view:

 [self.view addSubview:self.scrollView];

I get this error during runtime:

   0x132b61:  calll  0x132b66;   CA::Layer::ensure_transaction_recursively(CA::Transaction*) + 14
   EXC_BAD_ACCESS(code=2 address=0xbf7ffffc)

If I do not add it as a subview in the code, the view controller opens and the scrollview is black and does not scroll.

Solution

  • Check if you init with your scrollView with frame:

    self.scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 280, 360)];

    Remember also to set contentSize bigger than frame, for example:

    self.scrollView.contentSize = CGSizeMake(2*280, 360);

    Also add delegate in your interface:

    <UIScrollViewDelegate>

    And delegate it:

    self.scrollView.delegate = self;
