I'm using HMSegmentedControl in my application. I created a HMSegmentedControl instance in view controller A, then jumped to view controller B to collect data, like this:
[self presentViewController:vc animated:YES completion:nil];
Then I went back to view controller A and changed the titles of HMSegmentedControl according to the values from view controller B. I used setSectionTitles: to do the job. The titles did not refresh until I clicked one of them, but I want it refresh immediately. How to do it?
I've tried self.view setNeedsDisplay but did not work.
setNeedsDisplay should do what you need. You just need to call it on the segmented control, not the view controller's view.
[segmentedControl setNeedsDisplay];
