react native 碰到的幾個坑。記錄如下。

1.com.facebook.react.common.JavascriptException: undefined is not an object (evaluating 'n.internals.offset[e]'), stack:

[email protected]:3247

[email protected]:2792

<unknown>@728:4023

<unknown>@23:1787

解決辦法：

更改檔案   node_modules/react-native-swiper/src/index.js 398 line add
if(offset === undefined || this.internals.offset === undefined){ return; }

———————————————————

2. react-native 除錯的時候會有報錯：日誌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.

reactConsoleErrorHandler @ ExceptionsManager.js:71

console.error @ YellowBox.js:61

_handleLongDelay @ Touchable.js:596

解決辦法：

My practical solution was to edit react-native source code at:

node-modules/react-native/Libraries/Components/Touchable/Touchable.js

Here I've changed "console.error" to "console.log" at line 628, this way I receive the message, however my app is not interrupted and the error is "dissmissed"

3.react native 類似安卓的viewpage 輪播圖片的時候，應用的控制元件有報錯，cannot read property x of undefined react native  。android 某些機型輪播無限滾動情況。

解決辦法：

node_modules/react-native-swiper/src/index.js 171 line add

更改為：autoplayTimeout: 3,

可以避免cannot read property x of undefined react native 這個報錯，但實際上並沒有完全解決有些機型比如魅族，速度超快無限輪播的情況。
