中文介绍

ESTabBarController is a highly customizable TabBarController component, which is inherited from UITabBarController.

Why?

In real-world development, we may encounter the situation of customizing the UITabBar. For instance: change font style, add animation, and use bigger items. However it's hard to do with UITabBarItem.

With ESTabBarController, You can easily achieve these！

-	Feature	Description
1	Default style	You can get a system-like style by initializing the TabBar with ESTabBarController directly. </p> UITabBarController style: </p> </p> ESTabBarController default style: </p>
2	Default style with "More" item	If the items are more than the maximum number of displays, there will be a "More" item. </p> UITabBarController with "More": </p> </p> ESTabBarController with "More": </p>
3	Mix UITabBarItem and ESTabBarItem	You can set any item as you want, including UITabBarItem and ESTabBarItem. </p> ESTabBar and UITabBar mixed style: </p> </p> ESTabBar and UITabBar mixed style with "More": </p>
4	UIKit attributes	ESTabBarController is compatible with UITabBarController, UITabBar and UITabBarItem's most API attributes. You can migrate to ESTabBarController without any modification of the origin code. </p> Compatible with UITabBarController's selectedIndex: </p>
5	Any nesting with UINavigationController	Developing withUITabBarController, there are two common ways to handle layers: </p> First : </p> ├── UITabBarController </p> └──── UINavigationController </p> └────── UIViewController </p> └──────── SubviewControllers </p> Second : </p> ├── UINavigationController </p> └──── UITabBarController </p> └────── UIViewController </p> └──────── SubviewControllers </p> In the first case, need to set hidesBottomBarWhenPushed = true when pushing subViews. The second is not. </p> In ESTabBarController, add Container views to UITabBar to be compatible with these two ways。

TODO

1. The Containers' layout is purely based on code，using Autolayout will be better.
2. When there is "More," if edited, problems occur.
3. Partial UITabBarItem attributes are not bridge to ESTabBarItem.
4. The picture of 'More' item in ESTabBarItemMoreContentView is not set into framework, plan to convert it to CGBitmap.
