ipad 2 camera support detection

Question

I have an app that uses the following Macro:

#define IS_IPAD ([[UIDevice currentDevice] respondsToSelector:@selector(userInterfaceIdiom)] && [[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)

which works very well for me.

However, I was using it to turn off the option of taking a photo in the app.

How can I detect if the camera option is available regardless of device?

Answer 1

[UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera];

That should work

Answer 2

See How to Detect Camera Existence with AVFoundation.

NSArray *videoDevices = [AVCaptureDevice devicesWithMediaType:AVMediaTypeVideo];
AVCaptureDevice *captureDevice = nil;

if ( [videoDevices count] > 0 ) // This device has one or more cameras
....
