UIScrollView is unresponsive

问题

I have a UIViewController with a UIScrollView inside, all the content is displayed in the scrollview correctly, but for some reason I can't scroll thru it and all buttons are unresponsive.

UIScrollView *_scrollView;

_scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 768, 1024)];
_scrollView.pagingEnabled = YES;
_scrollView.showsHorizontalScrollIndicator = NO;
_scrollView.showsVerticalScrollIndicator = NO;
_scrollView.delegate = self;
_scrollView.backgroundColor = [UIColor redColor];
[self.view addSubview:_scrollView];


NSInteger yPos = 175;

for(Issue *issue in _dataModel.issues)
{
    // Create some items and add them to the scrollview
    [_scrollView addSubview:tmpItem.view];

    yPos += 140;
}

_scrollView.contentSize = CGSizeMake(768, yPos + 50);

I set the contentSize correctly, I use the same technique in a different view and there it just works fine. Not sure if I'm missing something here.

Do like this hope it will solve your issue.

scrollView=[[UIScrollView alloc] initWithFrame:CGRectMake(0, 0,320, 460)];
[scrollView setScrollEnabled:YES];
[scrollView setContentSize:CGSizeMake(320,600)];
[self.view addSubView:scrollView];
