Only ARC. 11 | 12 | ## Adding KKNavigationController to your project 13 | 14 | Include KKNavigationController wherever you need it with `#import "KKNavigationController.h"`. 15 | 16 | ### Source files 17 | 18 | Alternatively you can directly add the `KKNavigationController.h`& `KKNavigationController.m` source files to your project. 19 | 20 | 1. Download the [latest code version](https://github.com/Coneboy-k/KKNavigationController/archive/master.zip) or add the repository as a git submodule to your git-tracked project. 21 | 2. Open your project in Xcode, then drag and drop `KKNavigationController.h`& `KKNavigationController.m` onto your project (use the "Product Navigator view"). Make sure to select Copy items when asked if you extracted the code archive outside of your project. 22 | 3. Include KKNavigationController wherever you need it with `#import "KKNavigationController.h"`. 23 | 24 | ## Usage 25 | 26 | self.viewController = [[KKNavigationController alloc] 27 | initWithRootViewController: 28 | [[TSViewController alloc]init]]; 29 | 30 | 31 | ## Who use 32 | 33 | >图说 http://www.tushuoapp.com/ 34 | 35 | 36 | ## License 37 | 38 | This code is distributed under the terms and conditions of the [MIT license](LICENSE). 39 | 40 | ## Change-log 41 | 42 | A brief summary of each KKNavigationController release can be found on the [wiki](https://github.com/Coneboy-k/KKNavigationController/wiki). 43 | -------------------------------------------------------------------------------- /SHOW_GIF/18.gif: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/Coneboy-k/KKNavigationController/11356916b26ca1e50882f1f3a215b0fe60f41471/SHOW_GIF/18.gif --------------------------------------------------------------------------------
