Linking.removeEventListener('url', onReceiveURL);
removeEventListener 已弃用。
这就是我的 IDE 的建议:
EventEmitter.removeListener('url', ...):该方法已被弃用。 请在返回的订阅上使用
remove()
。EventEmitter.addListener
// Custom function to subscribe to incoming links
subscribe(listener: (deeplink: string) => void) {
// First, you may want to do the default deep link handling
const onReceiveURL = ({url}: {url: string}) => listener(url);
// Listen to incoming links from deep linking
Linking.addEventListener('url', onReceiveURL);
const handleDynamicLink = (
dynamicLink: FirebaseDynamicLinksTypes.DynamicLink,
) => {
listener(dynamicLink.url);
};
const unsubscribeToDynamicLinks = dynamicLinks().onLink(handleDynamicLink);
return () => {
unsubscribeToDynamicLinks();
Linking.removeEventListener('url', onReceiveURL);
};
我尝试了很多方法,但似乎没有任何效果。
没有找到任何具体信息。
有什么帮助可以解决吗?
编辑 -> 我将进一步调查,但到目前为止它正在工作:
const unsubscribeToDynamicLinks : any = ...
then in return :
return () => {
unsubscribeToDynamicLinks().remove('url', onReceiveURL);};
对于新 API,它是这样工作的:
useEffect (() => {
const subscription = Linking.addEventListener('url', onReceiveURL);
return () => subscription.remove();
}, [])
对于类组件,您可以使用如下所示的内容:
class MyClass extends Component {
constructor(props){
super(props)
this.changeEventListener = null
}
componentDidMount(){
// or you can use constructor for this
this.changeEventListener = AppState.addEventListener('change', () => {
// your listener function
})
}
componentWillUnmount() {
this.changeEventListener.remove()
}
}
AppState.addEventListener('change', handleAppStateChange);
return () => {
AppState.removeEventListener('change', handleAppStateChange);
};
由于removeEventListener已被弃用,所以我将上面的代码行替换为:
const 订阅 = AppState.addEventListener( '改变', 处理AppStateChange ); 返回()=> { 订阅.删除(); };
