Support device rotation. 11 | 12 | Installation 13 | ========================== 14 | 15 | #### Cocoapod Method:- 16 | 17 | `pod 'TCTitleLoading'` 18 | 19 | #### Source Code Method:- 20 | Add files in folder TCTitleLoading to your project. 21 | 22 | ##How To Get Started 23 | 24 | 1. In your Appdelegate.m, import TCTitleLoadingManager and set custom color, you can skip this step if you want to use the default black color: 25 | 26 | ``` 27 | - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 28 | // Override point for customization after application launch. 29 | 30 | //Set custom color for dots 31 | [TCTitleLoadingManager setDotColor:[UIColor orangeColor]]; 32 | return YES; 33 | } 34 | ``` 35 | 36 | 2.Start the loading by calling method startAnimationTitle in your view controller: 37 | 38 | ``` 39 | [self startAnimationTitle]; 40 | ``` 41 | 42 | 3.Start the loading by calling method startAnimationTitle in your view controller: 43 | 44 | ``` 45 | [self stopAnimationTitle]; 46 | ``` 47 | 4.If you want to skip the title loading for some pages, just tell the manager: 48 | 49 | ``` 50 | [TCTitleLoadingManager SkipTitleLoadingForClass:[self class]]; 51 | ``` 52 | 53 | Thanks 54 | --- 55 | This project is inspired by [XHLoadingNavigationItemTitleView](https://github.com/JackTeam/XHLoadingNavigationItemTitleView). 56 | The dot loading view is [TYDotIndicatorView](https://github.com/itouch2/TYDotIndicatorView) 57 | 58 | LICENSE 59 | --- 60 | Distributed under the MIT License. 61 | 62 | Author 63 | --- 64 | If you wish to contact me, email at: chuchuanming@gmail.com 65 | 66 | Blog 67 | --- 68 | [http://travelchu.com](http://travelchu.com) -------------------------------------------------------------------------------- /TCTitleLoading.podspec: -------------------------------------------------------------------------------- 1 | Pod::Spec.new do |s| 2 | 3 | s.name = "TCTitleLoading" 4 | s.version = "0.0.3" 5 | s.summary = "This is a loading in the bottom of navigation bar title area." 6 | 7 | s.description = <<-DESC 8 | Make you navigationbar has a loading view under title.
