Removing subviews from UIScrollView

I need to remove image subviews from a ScrollView and I tried removing from the array of subviews but that is an NSArray which is immutable.

How 开发者_如何学Ccan a subview be removed from the scrollviews array of subviews?

    NSArray *viewsToRemove = [scrollView subviews];
    for (UIView *v in viewsToRemove) [v removeFromSuperview];

You can do this,

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

This will remove all subviews of a UIScrollView but its scroll indicators: _scrollView.showsHorizontalScrollIndicator = _scrollView.showsVerticalScrollIndicator = NO; [_scrollView.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)]; _scrollView.showsHorizontalScrollIndicator = _scrollView.showsVerticalScrollIndicator = YES;

for (UIView *v in [scrollView subviews]) {
    [v removeFromSuperview];       
}

Call -removeFromSuperview on the subview.

Swift

for subview in scrollView.subviews {
    subview.removeFromSuperview()
}
