React Native如何每次唤醒APP都执行一段代码

1 async componentDidMount () {
2    AppState.addEventListener(‘change‘, this.handleAppStateChange);
3 }
4 
5 componentWillUnmount () {
6    AppState.removeEventListener(‘change‘, this.handleAppStateChange)
7 }

1 handleAppStateChange = (appState) => {
2     if (appState === ‘active‘) {
3             // 获取剪贴板内容
4             getClipboardShare()
5     }
6 };

1 export const getClipboardShare = () => {
2     Clipboard.getString().then(res => {
3         console.log(‘剪贴板复制‘, res);
4         if(res.indexOf(‘¢‘)) {
5             const shareCode = res.split(‘¢‘)[1].split(‘¢‘)[0];
6             console.log(‘截取的code‘, shareCode);
7         }
8     });
9 };
