我正在使用react-native-piechart來呈現單個圖表。我已將ART.xcodeproj添加到我的圖書館。我還將libART.a添加到我的Build Phases > Link Binary With Libraries。React Native - NSInvalidArgumentException
當我渲染圖表時，我的應用程序崩潰。當運行react-native log-ios我得到以下堆棧跟蹤

我已經試過
- 經紗取出包，並從Xcode中移除
ART.xcodeproj和libART.a，然後重新安裝。 - 我試過了多個圖表庫 - 這個問題依然存在。
- 我創建了一個全新的項目來測試庫不會引起問題，他們工作得很好。
你應該該報告爲圖書館的發展。 'NSArray'類沒有'length'方法，但只有[count]（https://developer.apple.com/reference/foundation/nsarray/1409982-count?language=objc）方法。這是一個bug或者在本地ObjC的'NSArray'類之上實現的一些奇怪的擴展。 –
我不相信這是圖書館@StanislavPankevich的問題，它已經工作了3-4周，並且在單獨的React Native項目中工作。我想也許這是我不小心點擊Xcode的東西。 – Dan
我唯一指出的是數組而不是字符串被傳遞給'RNSVGPathParser'的初始值設定項。它試圖計算一個字符串的長度，但是碰到了數組，因此崩潰了。我是Objective-C開發人員，不熟悉ReactNative，所以我不能說爲什麼圖書館走錯了路。 –
