When I run SDSegmentedControl Demo, I try click Disable Segement Button, At last, The app will crash. I found this code don't check selectedSegmentIndex.
(void)setEnabled:(BOOL)enabled forSegmentAtIndex:(NSUInteger)index { [self segmentAtIndex:index].enabled = enabled;
if (index == self.selectedSegmentIndex) { self.selectedSegmentIndex = [self firstEnabledSegmentIndexNearIndex:index]; } }
The Demo App Crash Log is:
