please help me out im using version 3.1.2 on iphone 2g.

	pick.showsCameraControls = NO;
	pick.navigationBarHidden = YES;
	pick.toolbarHidden = YES;
	pick.wantsFullScreenLayout = NO;

	NSLog(@"1:%f,%f",pick.cameraViewTransform.ty,pick.cameraViewTransform.tx); //<-- first i get 0.00, 0.00 here.

	pick.cameraViewTransform = CGAffineTransformScale(pick.cameraViewTransform, 0.5, 0.5);
	pick.cameraViewTransform = CGAffineTransformTranslate(pick.cameraViewTransform, 50.0, 100.0);

	NSLog(@"2:%f,%f",pick.cameraViewTransform.ty,pick.cameraViewTransform.tx); //<-- second i get 50.0, 25.0 here.
	
	UIButton *btnCapture = [UIButton buttonWithType:UIButtonTypeRoundedRect];
	btnCapture.frame = CGRectMake(0, 430, 320, 40);
	[btnCapture addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
	[pick.view addSubview:btnCapture];
	
	
	
	[self presentModalViewController:pick animated:NO];
	pick.cameraViewTransform = CGAffineTransformTranslate(pick.cameraViewTransform, 50.0, 100.0);
	[pick release];
	NSLog(@"3:%f,%f",pick.cameraViewTransform.ty,pick.cameraViewTransform.tx); //third i get 100.00, 50.00
}

-(IBAction) buttonPressed:(id) sender{
	NSLog(@"buttonPressed1:%f,%f",pick.cameraViewTransform.ty,pick.cameraViewTransform.tx); //after camera loaded i push this button
//i get buttonPressed1:50.00,25.00
	pick.cameraViewTransform = CGAffineTransformTranslate(pick.cameraViewTransform, 50.0, 100.0);
	NSLog(@"buttonPressed2:%f,%f",pick.cameraViewTransform.ty,pick.cameraViewTransform.tx); //<- and here i get 100.00, 50.00
}

Apparently displaying the controller with the modal view changes the transform somewhere later in the run loop.
Perhaps, instead you can wait for it to appear and then create an animation to move the view to where you want it.
