照片框架崩溃：'This application is not allowed to access Photo data.'
Photos Framework crash: 'This application is not allowed to access Photo data.'
如果未授予照片访问权限并且请求权限的对象即将解除分配，应用程序会崩溃。
Apple 的示例代码（用于照片框架）也崩溃了。
我的应用崩溃并显示以下堆栈跟踪：

任何指点将不胜感激。
这是预期的行为。
在您使用照片框架的任何方法（如获取、更改）之前，请检查照片库的权限状态。这是通过调用 PHPhotoLibrary 的 authorizationStatus 方法来完成的。如果此方法 PHAuthorizationStatusNotDetermined，请使用 requestAuthorization 方法请求许可。如果 authorizationStatus 的值 PHAuthorizationStatusDenied 优雅地下降。
要点是让 requestAuthorization 提示访问照片库而不是直接获取方法。
我也有过同样的经历。但是，要重现退出视图控制器并释放它是不够的，还需要在模拟器中模拟内存警告。这迫使崩溃。
所以，我的解决方案是不使用 PHImageManager 作为全局变量，而是在需要时访问它。而不是这个：
private let imageManager = PHImageManager.defaultManager()
...
imageManager.requestImageForAsset(....)
我在需要的时候喜欢这个：
PHImageManager.defaultManager().requestImageForAsset(....)
我的崩溃情况是使用 PHCachingImageManager 作为 属性。
fileprivate let imageManager = PHCachingImageManager()
我通过将其更改为惰性变量来修复它：
fileprivate lazy var imageManager = PHCachingImageManager()
PHImageManager 在初始化时添加调度源事件 DISPATCH_SOURCE_TYPE_MEMORYPRESSURE。
当收到内存警告时，Photos 框架将尝试删除此事件处理程序中的缓存数据。届时，如果你有调用但没有获得授权，会导致崩溃
导致崩溃
对我来说，如果用户未授予照片权限，它会在 11 和 12 版本上崩溃，但在 iOS13 上工作正常。下面的行导致了问题。
fileprivate var imageManager = PHImageManager() // Crash
fileprivate lazy var imageManager = PHImageManager() // fixed the crash.
