Rotating wheel

[C_2]

Hi,

I am having a few problems with a rotating wheel where the user drags a wheel and this rotates in this direction. My wheel rotates when the user drags it but I have two problems with it.

1. when you click and drag slightly the wheel automatically rotates everything to reach this position

2. The coordinates of the buttons, etc are not changing even though they are being rotated.

-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {   
    }

    -(void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
        NSSet *allTouches = [event allTouches];

        int len = [allTouches count]-1;

        UITouch *touch =[[allTouches allObjects] objectAtIndex:len];
        CGPoint location = [touch locationInView:[self superview]];
        float theAngle = atan2( location.y-self.center.y, location.x-self.center.x );

        totalRadians = theAngle;

        [self rotateImage:theAngle];

    }

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
}

-(void) rotateImage:(float)angleRadians{

    self.transform = CGAffineTransformMakeRotation(angleRadians);
    CATransform3D rotatedTransform = self.layer.transform;
    self.layer.transform = rotatedTransform;    
}
