I can understand that it might behave that way. It's not in and of itself unreasonable, although in my opinion if the selected segment changes visually, it's kind of weird not to send the message since the key isn't UIControlEventValueChangedButReallyIOnlyCareAboutWhenTheChangeCameFromATouch.
The irksome thing is that it used to work and now doesn't and there's no API diff around selectedSegment and the wording in the documentation didn't change between iOS 7 and 8. So I don't know if it's an intentional decision or an oversight. -- Daniel Blakemore Pixio Software On Tue, Oct 14, 2014 at 9:20 PM, Richard Charles <[email protected]> wrote: > Not sure about iOS but on OS X programmatically calling > > [NSSegmentedControl setSelectedSegment:] > > does not trigger the target / action message. > > You need to programmatically respond after setting the selected segment. > > Richard Charles > > On Oct 14, 2014, at 6:55 PM, Daniel Blakemore <[email protected]> > wrote: > > > I have a simple problem.
