在iOS上向地图添加音频 [英] Add audio to Map on iOS

问题描述

我现在有一张地图，上面有几个非常接近的点.现在，当用户点击注释时，会弹出一个带有位置名称的弹出窗口.我如何才能播放有关该位置的音频?

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?

我对暂停按钮等还不是很着迷，现在我想知道如何在其中实现音频！

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

文本到语音的转换

更新:

将委托添加到您的MKMapView.例如，它可能是self

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

self.mapView.delegate = self;

(自身应向MKMapViewDelegate确认).并实现委托的方法

(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];
}
