如果未授予照片访问权限，并且要释放权限的对象即将被释放，则应用程序崩溃。
苹果的示例代码(用于“照片”框架)也崩溃了。
我的应用因以下堆栈跟踪而崩溃:
***由于未捕获的异常“NSObjectInaccessibleException”而终止应用程序，原因:“不允许该应用程序访问照片数据。”
***首先抛出调用堆栈:

libc++ abi.dylib:以类型为NSException的未捕获异常终止
任何指针将不胜感激。
最佳答案
这是预期的行为。
在使用Photos Framework的任何方法(例如，获取，更改)之前，请检查对Photo-Library的权限状态。这是通过调用authorizationStatus的PHPhotoLibrary方法来完成的。如果此方法为PHAuthorizationStatusNotDetermined，请使用requestAuthorization方法询问权限。如果authorizationStatus的值是PHAuthorizationStatusDenied，请适当降低。
要点是让requestAuthorization提示您访问Photo-Library，而不是直接获取方法。
关于ios - 照片框架崩溃: 'This application is not allowed to access Photo data.' ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/33266346/
