Question

我正在使用React Native构建应用程序，并希望使用MapBox GL Component来渲染地图并添加注释。我正在尝试从github repo中实现this example。

我尽可能地遵循安装说明，但是当地图加载时，注释不存在。我明白了：

Xcode中的此错误（3次）：

和这一个（只有一次）：

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`.'

我已将地图中心设置为与第一个注释相同的位置，因此它肯定应该在视图中。

所有其他功能似乎都有效（重新定位地图，缩放等）。我也见过example used here并且它有效（至少在iOS 8上）。

有什么想法吗？它可能与iOS9相关吗？我的代码如下：

Xcode中是否有任何错误？此外，从中删除不必要的代码并尝试向地图添加注释可能是个好主意。

如果你也可以尝试在反应游乐场上运行代码，我可以帮助更好地调试这个，这是一个例子：reddit

无法看到MapBox React Native GL注释
