A collection of well-documented iOS classes for making life easierSSToolkit可以说是iOS开发者最常使用的工具类之一，该开源项目提供了一个完整的iOS类库集合，用于解决iOS开发者在开发过程中常碰到的一些问题，比如追踪一款设备是否具有视网膜显示屏或是否能剪裁图片，包含SSCollectionView、SSGradientView、SSSwitch等诸多非常方便的类。

SSToolkit

SSToolkit is a grab bag of iOS goodness. It used to be a giant collection of classes that I started in 2008. This was getting out of hand. That version is completely deprecated. (Read more on that.)

Now SSToolkit is made up of several libraries you can use independently. SSToolkit is now just a header file and a podspec with dependencies for each library.

Here’s what’s included:

• SAMAddressBar — Clone of Safari's address bar from iOS 6.
• SAMBadgeView — Simple badge view.
• SAMGradientView — Easy gradients in UIKit.
• SAMHUDView — Kinda okay HUD.
• SAMLabel — UILabel with vertical alignment and text insets.
• SAMLoadingView — Simple loading view.
• SAMCircleProgressView — Determinate, circular progress view.
• SAMRateLimit — Simple utility for only executing code every so often.
• SAMTextField — Handy UITextField additions like insetting text.
• SAMTextView — Add a placeholder to UITextView.
• SAMWebView — Push UIWebView to its limits.
• SAMCategories — A collection of useful Foundation and UIKit categories.

Several of these libraries have had big improvements since their abstraction from SSToolkit.
