M13AsynchronousImageView is a category extension of UIImageView that loads images asynchronously. Just pass the URL of the image, local or external, and the UIImageView will take care of loading the image in the background. This is perfect for UITableViews and UICollectionViews, as it doesn't block the main thread with image loading, so the main interface is still responsive.

M13InfiniteTabBar is an elegant replacement for UITabBar. UITabBar becomes a problem when you have more than five view controllers that have the need to be accessed an equal amount of times. It maskes no sense to hide any of the tabs away under the "More" tab. Plus it takes two extra clicks to reach the view controllers behind the "More" button. M13InfiniteTabBar solves this problem by having all the view controllers on a single level. The "extra" view controllers can be reached by scrolling the tab bar left or right. The scrolling does pose a problem though, in which direction is my offscreen tab? M13InfiniteTabBar solves this by putting the tabs in an infinite scrolling loop. Any tab can be reached by scrolling in any direction. M13InfiniteTabBar also has a few other features that UITabBar doesn't offer on top of that.
A cross between NSArray and NSDictionary. It holds an ordered list of objects and keys. All of which can be accessed by index, or key.

It has methods comparable to all of NSArray's methods and all of NSDictionary's methods. It also supports NSCoding, NSCopying, KVO, and supports NSFastEnumeration over the objects or keys. It is the only fully implemented ordered dictionary class.
