SYNScrollViewObserverEffects is a set of classes that observe the content offset of one scrollview and generate different effects. The primary goal was to be unobtrussive and able to react to changes in a scroll view without having to be the delegate. Effects included:

1. Parallax scrolling to show depth of UI.
2. Enlarge a view when the scrollview is pulled down too far.
3. An image blur of a UIImageView image.
4. An effect to show and hide the a Navigation bar based on scrolling.

Note: The blur effect in this library is requires iOS 7+. All else should work with at least iOS 6.

Usage

To run the example project; clone the repo, and run pod install from the Project directory first.

Using in a project can be done with the following code.

self.parallaxObserver = [[SYNParallaxScrollObserver alloc] initWithObservedScrollView:self.observed parallaxedScrollView:self.parallaxed];
[self.parallaxObserver startObserving];

Requirements

To use all of the effects iOS 7 is required.
