How can a subview be removed from the scrollviews array of subviews?
NSArray *viewsToRemove = [scrollView subviews];
for (UIView *v in viewsToRemove) [v removeFromSuperview];
你可以这样做,
[[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.
