Reply To: multiple OpenEars delegates are getting mixed up with ARC on

[gsboris]

well, i implemented all methods as you have them in tutorial.
Since nil-ing delegate I does not mix controllers anymore, but it still crashes when I go back to VC1 after i used TTS on VC2 and try to make it say:
[self.fliteController say:[txtArr objectAtIndex:hlIndx] withVoice:self.slt];

However it does not crash if I make it say on VC1, go to VC2 and return to VC1 and make it say.
It seems to crash if I make it say on VC2 and return to VC1 and try make it say again.

here is my methods:

-(void)viewWillAppear:(BOOL)animated{
[self.openEarsEventsObserver setDelegate:self];
}
-(void)viewWillDisappear:(BOOL)animated{
self.openEarsEventsObserver.delegate=nil;
}
– (OpenEarsEventsObserver *)openEarsEventsObserver {
if (openEarsEventsObserver == nil) {
openEarsEventsObserver = [[OpenEarsEventsObserver alloc] init];
}
return openEarsEventsObserver;
}
– (FliteController *)fliteController {
if (fliteController == nil) {fliteController = [[FliteController alloc] init];}
return fliteController;
}
– (Slt *)slt {
if (slt == nil) {slt = [[Slt alloc] init];}
return slt;
}

here is bt:
