1. How it works
2. Usage and example

1. The camera is enabled by modifying the simulator plists.
2. A call is made to:

-(void)mockCameraWithImageURL:(NSString*)url delay:(NSInteger)delay;

This sets up an NSTimer that will fire after delay seconds. The timer handler will pull the image from the given URL, and present it to this delegate method:

- (void)imagePickerController:(UIImagePickerController *)thePicker didFinishPickingMediaWithInfo:(NSDictionary *)info

Locate the plist files for the simulator(s) that you want to change, for me these are:

/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.0.sdk/System/Library/CoreServices/SpringBoard.app/simulator.plist
/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.2.sdk/System/Library/CoreServices/SpringBoard.app/simulator.plist

As the iPad doesn’t have a camera it makes no sense to enable it – but if you want to, also change:

/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.2.sdk/System/Library/CoreServices/SpringBoard.app/iPadSimulator.plist
/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.0.sdk/System/Library/CoreServices/SpringBoard.app/iPadSimulator.plist

Open each of the plist files in the Property List Editor:

1. Expand Root
2. Add a new child to the capabilities dictionary, Key: “still-camera”, Type “Boolean”, Value: Ticked
3. Save the plist file

You’ll probably need to copy the plist files somewhere else to be able to change them, then copy them back.

#ifdef DEBUG
#import "UIImagePickerController+SimulatedCamera.h"
#endif

  UIImagePickerController *picker = [[UIImagePickerController alloc] init];
  picker.delegate = self;
  picker.sourceType = UIImagePickerControllerSourceTypeCamera;
  picker.showsCameraControls = YES;

#ifdef DEBUG
  [picker mockCameraWithImageURL:@"http://localhost/test.jpg" delay:2.0];
#endif

  [self presentModalViewController:picker animated:YES];

  [picker release];

The default delay is 2 seconds, if not specified.
