View controller can watch for show/hide keyboard actions and scroll to first responder view without any manipulation. 5 | - [LGTableViewController](https://github.com/Friend-LGA/LGViewControllers/blob/master/LGViewControllers/LGTableViewController/LGTableViewController.h) can do everything like LGScrollViewController, more than that it can reload table view asynchronously, without freezing UI. 6 | - [LGCollectionViewController](https://github.com/Friend-LGA/LGViewControllers/blob/master/LGViewControllers/LGCollectionViewController/LGCollectionViewController.h) can do everything like LGScrollViewController, more than that it has easy initialization methods, to faster setup layout. 7 | - [LGWebViewController](https://github.com/Friend-LGA/LGViewControllers/blob/master/LGViewControllers/LGWebViewController/LGWebViewController.h) is view controller with LGWebView as root view, that has LGPlaceholderView by default. View controller has easy initialization methods, to use it without subclassing. 8 | - [LGViewControllerAnimator](https://github.com/Friend-LGA/LGViewControllers/blob/master/LGViewControllers/LGViewControllerAnimator/LGViewControllerAnimator.h) is class that implement slide animation between view controllers. 9 | 10 | ## Installation 11 | 12 | ### With source code 13 | 14 | - [Download repository](https://github.com/Friend-LGA/LGViewControllers/archive/master.zip), then add [LGViewControllers directory](https://github.com/Friend-LGA/LGViewControllers/blob/master/LGViewControllers/) to your project. 15 | - Also you need to install libraries: 16 | - [LGPlaceholderView](https://github.com/Friend-LGA/LGPlaceholderView) 17 | - [LGRefreshView](https://github.com/Friend-LGA/LGRefreshView) 18 | 19 | ### With CocoaPods 20 | 21 | [CocoaPods](http://cocoapods.org/) is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries in your projects. See the "Get Started" section for more details. 22 | 23 | #### Podfile 24 | ``` 25 | platform :ios, '6.0' 26 | pod 'LGViewControllers', '~> 1.0.0' 27 | ``` 28 | 29 | ## Usage 30 | 31 | In the source files where you need to use the library, import the header file: 32 | 33 | ```objective-c 34 | #import "LGViewControllers.h" 35 | ``` 36 | 37 | Or you can use sublibraries separately, depend of your needs: 38 | 39 | ```objective-c 40 | #import "LGScrollViewController.h" 41 | #import "LGTableViewController.h" 42 | #import "LGCollectionViewController.h" 43 | #import "LGWebViewController.h" 44 | 45 | #import "LGScrollView.h" 46 | #import "LGTableView.h" 47 | #import "LGCollectionView.h" 48 | #import "LGWebView.h" 49 | 50 | #import "LGViewControllerAnimator.h" 51 | ``` 52 | 53 | ### More 54 | 55 | For more details try Xcode [Demo project](https://github.com/Friend-LGA/LGViewControllers/blob/master/Demo) and see files: 56 | - [LGScrollViewController.h](https://github.com/Friend-LGA/LGViewControllers/blob/master/LGViewControllers/LGScrollViewController/LGScrollViewController.h) and [LGScrollView.h](https://github.com/Friend-LGA/LGViewControllers/blob/master/LGViewControllers/LGScrollViewController/LGScrollView.h) 57 | - [LGTableViewController.h](https://github.com/Friend-LGA/LGViewControllers/blob/master/LGViewControllers/LGTableViewController/LGTableViewController.h) and [LGTableView.h](https://github.com/Friend-LGA/LGViewControllers/blob/master/LGViewControllers/LGTableViewController/LGTableView.h) 58 | - [LGCollectionViewController.h](https://github.com/Friend-LGA/LGViewControllers/blob/master/LGViewControllers/LGCollectionViewController/LGCollectionViewController.h) and [LGCollectionView.h](https://github.com/Friend-LGA/LGViewControllers/blob/master/LGViewControllers/LGCollectionViewController/LGCollectionView.h) 59 | - [LGWebViewController.h](https://github.com/Friend-LGA/LGViewControllers/blob/master/LGViewControllers/LGWebViewController/LGWebViewController.h) and [LGWebView.h](https://github.com/Friend-LGA/LGViewControllers/blob/master/LGViewControllers/LGWebViewController/LGWebView.h) 60 | - [LGViewControllerAnimator.h](https://github.com/Friend-LGA/LGViewControllers/blob/master/LGViewControllers/LGViewControllerAnimator/LGViewControllerAnimator.h) 61 | 62 | ## License 63 | 64 | LGViewControllers is released under the MIT license.
