Question

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

Answer 1

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)];
