Add audio to Map on iOS

问题

I have a map right now with several points on it that are quite close to each other. Right now when a user taps the annotation a little pop up occurs with the location name on it. How could I have it so that a piece of audio about that location plays?

I'm not too fussed about pause buttons etc yet, right now I want to know how I'd implement audio into this!

回答1:

Use AVSpeechSynthesizer

AVSpeechSynthesizer *synthesizer = [[AVSpeechSynthesizer alloc]init];
AVSpeechUtterance *utterance = [AVSpeechUtterance speechUtteranceWithString:@"Some random text that you want to be spoken"];
[utterance setRate:0.7];
[synthesizer speakUtterance:utterance];

Text to speech conversion

UPDATE:

Add delegate to your MKMapView. For example it could be self

self.mapView.delegate = self;

(self should confirm to MKMapViewDelegate). And implement delegate's method

- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)anView
{
    AVSpeechSynthesizer *synthesizer = [[AVSpeechSynthesizer alloc]init];
    AVSpeechUtterance *utterance = [AVSpeechUtterance speechUtteranceWithString:anView.annotation.title];
    [utterance setRate:0.7];
    [synthesizer speakUtterance:utterance];
}
