How do I test a camera in the iPhone simulator?
Is there any way to test the iPhone camera in the simulator without having to deploy on a device? This seems awfully tedious.
Solution 1:
There are a number of device specific features that you have to test on the device, but it's no harder than using the simulator. Just build a debug target for the device and leave it attached to the computer.
List of actions that require an actual device:
- the actual phone
- the camera
- the accelerometer
- real GPS data
- the compass
- vibration
- push notifications...
Solution 2:
I needed to test some custom overlays for photos. The overlays needed to be adjusted based on the size/resolution of the image.
I approached this in a way that was similar to the suggestion from Stefan, I decided to code up a "dummy" camera response.
When the simulator is running I execute this dummy code instead of the standard "captureStillImageAsynchronouslyFromConnection".
In this dummy code, I build up a "black photo" of the necessary resolution and then send it through the pipelined to be treated like a normal photo. Essentially providing the feel of a very fast camera.
CGSize sz = UIDeviceOrientationIsPortrait([[UIDevice currentDevice] orientation]) ? CGSizeMake(2448, 3264) : CGSizeMake(3264, 2448);
UIGraphicsBeginImageContextWithOptions(sz, YES, 1);
[[UIColor blackColor] setFill];
UIRectFill(CGRectMake(0, 0, sz.width, sz.height));
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
NSData *imageData = UIImageJPEGRepresentation(image, 1.0);
The image above is equivalent to a 8MP photos that most of the current day devices send out. Obviously to test other resolutions you would change the size.

I never tried it, but you can give it a try! iCimulator
