Calling a user's attention to a certain point on a screen should be simple, so we've created this MLPSpotlight class to make it quick and easy to insert and remove a spotlight within a view.
MLPSpotlight is a UIView subclass created to display a spotlight effect over a specific point on the screen in a convenient manner.
First, add the MLPSpotlight header and implementation file to your project. (.h & .m)
The easiest way to add a spotlight to a view is with the class method:
+ (id)addSpotlightInView:(UIView *)view atPoint:(CGPoint)centerPoint;
You can remove the spotlight later by calling:
+ (id)removeSpotlightsInView:(UIView *)view;
For more advanced options, see the header file of MLPSpotlight.
If you want a custom gradient for the spotlight you can pass your own CGGradientRef to the "spotlightGradientRef" property of a spotlight.
You can access a spotlight in a view through this method which returns an array with the existing spotlights in a view.
+ (NSArray *)spotlightsInView:(UIView *)view;
- Movable Spotlight: Some people have requested the ability to move a spotlight after it has been rendered.
