【问题描述】:
在 Android 模拟器中,以下代码可以正常工作,但在 iOS 中,它甚至不会进入 navigator.geolocation.getCurrentPosition。
我已经通过调试菜单更新了我的模拟器的自定义位置,但如果它甚至没有进入 navigator.geolocation.getCurrentPosition 我有点迷茫。
constructor(props) {
super(props);
this.state = {
focusedLocation: {
latitude: 37.4219999,
longitude: -122.0862462,
latitudeDelta: 0.0022,
longitudeDelta: Dimensions.get("window").width / Dimensions.get("window").height * 0.0122,
},
};
}
componentDidMount() {
console.log("did mount: ", this.state.grumblersLocation.latitude); //triggers iOS and Android
navigator.geolocation.getCurrentPosition(pos => {
console.log("raw pos lat: ", pos.coords.latitude); //triggers in Android only
this.setState({
focusedLocation: {
...this.state.grumblersLocation,
latitude: pos.coords.latitude,
longitude: pos.coords.longitude
}
}, () => {
console.log("state after pos lat: ", this.state.grumblersLocation.latitude); //triggers in Android only
});
},
err => {
console.log("Fetching the Position failed: ", err); //Not triggering on either
});
}
