FlexLib

FlexLib is an Objective-C layout framework for iOS. It's based on flexbox model which is standard for web layout. So the layout capability is powerful and easy to use. With FlexLib, you can write iOS UI much faster than before, and there are better adaptability. Flexbox is more general than autolayout. Flexbox is standard for web and it's also used in ReactNative, Weex, AsyncDisplayKit, Android. FlexLib has better readability. View the autolayout written by others is really boring. For page like the following image, you don't need UITableView any more. Just write everything in one xml. It's much simpler and maintainable. The calculation for height of complex UITableViewCell is really boring. With FlexLib, all the calculation is automatically. FlexScrollView (the subclass of UIScrollView) can manage its contentSize automatically. I'm sure it will save you a lot of time.
