A UIView which allows a manual and automatic scratching behavior.

I love CocoaPods and you will. Add a new line on your Podfile with 'STScratchView'.

You need only 2 files:

• STScratchView.h
• STScratchView.m

You need to create an UIView (or child UIView: UIImageView for example) and give this view to the STScratchView object via the -[STScratchView setHideView:(UIView *)hideView] method.

You can also define a UIBezierPath to create an automatic scratch with -[STScratchView setAutomaticScratchCurve:(UIBezierPath *)curvePath duration:(float)duration].

Build and run the project STScratchViewExample in Xcode to see STScratchView in action.

    STScratchView *scratchView = [[STScratchView alloc] initWithFrame:CGRectMake(20.0, 60.0, 280.0, 200.0)];
    [self.view addSubview:scratchView];

    UIView *hideView = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 280.0, 200.0)];
    [hideView setBackgroundColor:[UIColor redColor]];

    [scratchView setHideView:hideView];

It's easy!
