iOS10 模拟器上边运行【AVCaptureSession startRunning】崩溃。

Question

我在Xcode7.2上边运行，下边的代码

只是黑屏，但不会崩溃。
在Xcode8上运行，

崩溃了，
难道iOS10之后，只能在真机上边运行了吗。
小白求解~~~~

Answer 1

The simulator does not originally support this. It is recommended to use a real machine for debugging. If you have to run it on the simulator, just use code to block it:

#if !(TARGET_IPHONE_SIMULATOR)
[self.captureSession startRunning];
#endif

Answer 2

The operation involving calling the camera must require a real machine

Answer 3

There is no way to call the camera simulator, only the real machine can. Xcode 8 simulator getting the camera will cause a crash, you can use

UIImagePickerController *picker = [[UIImagePickerController alloc]init];
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;

Try it, in picker.sourceType = UIImagePickerControllerSourceTypeCamera; there is a problem here, it can be called using a real device.
