Remove the content in a UIScrollView Programmatically?

Question

How do you remove the content in a UIScrollView Programmatically? As I have to update the content in it frequently.

just use the `scrollView = nil` and `scrollView = [UIScrollView alloc] init];` — The iOSDev, Apr 11 '12 at 11:59

@Gray I believe you are correct. I believe I could have found my answer in there. But I spent quite a long time looking for the answer to this an never came across it. But I was searching for removing content from the UIScrollView not the subviews so that is probably why I didn't find it. Thanks +1. — Popeye, Apr 11 '12 at 14:58

I don't think that there is a difference between typical UIView:

for (UIView *v in [scrollView subviews])
    [v removeFromSuperView];

for(UIView *vw in [scrView subViews])
  [vw removeFromSuperView];

You can use this to remove contents in your scrollview

You can loop through your scroll view's subviews like:

for(UIView *subview in scrollView.subviews)
    [subview removeFromSuperview];

or you can use - [NSArray makeObjectsPerformSelector:] method like:

[scrollView.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)];
