I have a very terrible crash problem in my App when I use AVSpeechSynthesizer and I can't repetition it.
Here is my code, It's a singleton
- (void)stopSpeech {
if ([self.synthesizer isPaused]) {
return;
}
if ([self.synthesizer isSpeaking]) {
BOOL isSpeech = [self.synthesizer stopSpeakingAtBoundary:AVSpeechBoundaryImmediate];
if (!isSpeech) {
[self.synthesizer stopSpeakingAtBoundary:AVSpeechBoundaryWord];
}
}
self.stopBlock ? self.stopBlock() : nil;
}
-(AVSpeechSynthesizer *)synthesizer {
if (!_synthesizer) {
_synthesizer = [[AVSpeechSynthesizer alloc] init];
_synthesizer.delegate = self;
}
return _synthesizer;
}When the user leaves the page, I call the stopSpeech method。
Then I got a lot of crash messages
Here is a crash log:
