Hi Halle,
Unfortunately, the same problem persists on the device too. I checked it on iPad2 iOS7.1.1 app crashes if it tries to RE-USE the voice on the 1st VC that has been used on 2nd VC. Nil-ing voice obj, when leaving to 2nd VC, seems to solve this issue, cause it forces it to reinit the voice, when you return to work on the 1st VC.

TY for guiding me through this. Will check this same issue on real device, will see if it is the same and let you know. Best regards.

OK, I nil-ed voices before leaving the view and it cured it. does not crash anymore.

And, yes it is called with self.slt as you have in tutorial.

[gsboris]

i turned off observer – same issue.
i played with different voices: if I use slt on VC1 and rms on VC2 – it does not crash, i can go back and forth and it is fine!
Using same voice on both causes that. As soon as I use the same voice on VC2 and go back to VC1 it crashes while trying to say.

[gsboris]

well, my app is heavily relied on the observer though. It is TTS with word/sentence/paragraph highlights, I really need that observer to discern when and what to highlight. I will try something, perhaps w/o highlights for now. will get back to you. Thank you very much for your patience and expertise.

Could it be simulator issues? I am going to test it on real device first.

[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;
}

OK, thanks, will do that

[gsboris]

so now when I go back to VC1 it is crashing, that is

[gsboris]

IT IS WORKING NOW, sort of, but crashing
it does not call VC1 now from VC2 when I just .delegate=nil on view disappear

it is crashing while trying:
[fliteController say:[txtArr objectAtIndex:hlIndx] withVoice:self.slt];

[gsboris]

kk, will try and get back to u asap

[gsboris]

you are right, they both are called back, 1st on VC2 then on VC1.
1st I tried nil-ing everything i.e. fliteController,slt,openEarsEventsObserver.delegate,openEarsEventsObserver then just openEarsEventsObserver.delegate in both cases app crashes.
