我正在使用React Native構建應用程序，並且想要使用MapBox GL Component來渲染地圖並添加註釋。我正試圖從github回購中實施this example。看不到MapBox React Native GL註釋
我按照安裝說明操作，盡我所能，但在地圖加載，註釋不存在。我得到這個：
此錯誤在Xcode（3次）：

而這一次（僅一次）：
2015-10-14 20:45:09.328 [warn][tid:com.facebook.React.JavaScript] 'Warning: Failed propType: typeChecker is not a function. (In \'typeChecker(\npropValue,\ni,\ncomponentName,\nlocation,\npropFullName + \'[\' + i + \']\')\', \'typeChecker\' is undefined) Check the render method of `MapBoxDemo`.'
我已經設置了地圖中心與第一個註釋的位置相同，因此它肯定應該在視圖中。
所有其他功能似乎工作（重新映射地圖，縮放等）。我也看到了example used here，它起作用（至少在iOS 8上）。
任何想法？它可以與iOS9相關嗎？我的代碼如下：

我遇到了同樣的問題。似乎與「座標」鍵有關的問題。 – Jaec
