RN開發中的報錯以及告警

 報錯一:

Attempted to transition from state `RESPONDER_INACTIVE_PRESS_IN` to `RESPONDER_ACTIVE_LONG_PRESS_IN`, which is not supported. This is most likely due to `Touchable.longPressDelayTimeout` not being cancelled.

產生原因:

可能是在Touchablexxx在這組組件中調用onPress方法使產生

解決方法:

關閉debug報錯就不會產生,不會影響的項目的開發

告警一:

Warning: Can only update a mounted or mounting component. This usually means you called setState, replaceState, or forceUpdate on an unmounted component. This is a no-op.

Please check the code for the WindProfile component.

產生的原因:

在組件進行切換是調用的this.setState未能釋放/已經銷毀,而造成的告警

解決方法:

componentWillUnmount() {
    this.setState = (state, callback) => {
        return;
    };
}

告警二:

Warning: In next release empty section headers will be rendered. In this release you can use 'enableEmptySections' flag to render empty section headers.

產生原因:

頁面中存在空的數據

解決方法:

在listView中添加

enableEmptySections={true}
