development of camera, GPS, and accelerometer

[hogeo]

I wonder how I can develop an app using camera, GPS, or accelerometer.
Because iPhone simulator does not have actual camera, GPS and accelerometer, how did you guys usually see if your program works or not??

In the case of camera, can we use built-in camera when using simulator??

Thanks,

camera pretty much acts just like your photo library if you load up a UIImagePickerController. The only difference is you hit the button to take the picture and then resize/crop it if needed.

It gets passed back to the same delegates to handle the image.

As hijinks said with the simulator use the photo library in the camera picker. Then some code like the following to automatically use the camera when the app is on the iphone (code could be made shorter - tidy up as need be):

if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {

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

	picker.delegate = self;
	picker.allowsImageEditing = NO;
}
else if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {

	picker = [[UIImagePickerController alloc] init];
	picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

	picker.delegate = self;
	picker.allowsImageEditing = NO;
}
else {
	picker = nil;

	UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"No Camera Found"
	message:@"You need an iPhone with a camera to use this application."
	delegate:self
	cancelButtonTitle:@"Cancel"
	otherButtonTitles:@"Ok", nil];

	[alertView show];
	[alertView release];
}
