AVCaptureDevice类型在iPad上崩溃Objective-C

Question

我有与Apple文档相同的代码：https://developer.apple.com/library/archive/samplecode/AVCam/Listings/Objective_C_AVCam_AVCamCameraViewController_m.html#//apple_ref/doc/uid/DTS40010112-Objective_C_AVCam_AVCamCameraViewController_m-DontLinkElementID_7

NSArray<AVCaptureDeviceType> *deviceTypes = @[AVCaptureDeviceTypeBuiltInWideAngleCamera, AVCaptureDeviceTypeBuiltInDualCamera];

此行代码中断。

请参考下面的链接。这解决了我在iOS版本较低的iPad上崩溃相机的问题。

还要确保您的应用崩溃的位置。如果由于iOS版本较低版本的核心数据（NSPersistentContainer）而崩溃，请尝试使用：NSPersistentContainer。
