网上找了一大堆，没有解决的办法 ，主要是iOS10的适配问题，info.plist里没有加对。

访问相册，我只加了

<!-- 相册 --> 
<key>NSPhotoLibraryUsageDescription</key> 
<string>App需要您的同意,才能访问相册</string> 

然后运行程序就报错了

Class PLBuildVersion is implemented in both /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/AssetsLibr 
解决办法 ，还得补上一个东西

<!-- 媒体资料库 --> 
<key>NSAppleMusicUsageDescription</key> 
<string>App需要您的同意,才能访问媒体资料库</string>
