It works as a wrapper for the UITableView, defining its own delegate and data source methods which make working with tree data structures really easy. RATreeView is highly customizable and has a lot of features. Installation ----------------- ### CocoaPods [CocoaPods](http://www.cocoapods.org) is the recommended way to add RATreeView to your project. 1. Add additional entry to your Podfile. ```ruby pod "RATreeView", "~> 2.1.2" ``` 2. Install Pod(s) running `pod install` command. 3. Include RATreeView using `#import `. ###Source files 1. Downloaded the latest version of the library using [link](https://github.com/Augustyniak/RATreeView/archive/master.zip). 2. Copy content of the downloaded (and unzipped) zip file into your project by dragging it into Project's navigator files structure. Requirements ----------------- * Xcode 5 * iOS 7 or newer/tvOS 9 or newer Usage ----------------- Check out the demo for example usage of library. Make sure you read the [RATreeView documentation on Cocoa Docs](http://cocoadocs.org/docsets/RATreeView/2.1.2). ### Basics 1. Add following import in file of your project when you want to use RATreeView: ```objc // In case you are using RATreeView with CocoaPods #import ``` ```objc // In case you are using RATreeView by simply copying // source files of the RATreeView into your project #import "RATreeView.h" ``` 2. Simplest way to initialize and configure RATreeView: ```objc RATreeView *treeView = [[RATreeView alloc] initWithFrame:self.view.bounds]; treeView.delegate = self; treeView.dataSource = self; [self.view addSubview:treeView]; [treeView reloadData]; ``` 3. Implement required methods of the RATreeView's data source: ```objc - (NSInteger)treeView:(RATreeView *)treeView numberOfChildrenOfItem:(id)item { return item ? 3 : 0; } ``` ```objc - (UITableViewCell *)treeView:(RATreeView *)treeView cellForItem:(id)item treeNodeInfo:(RATreeNodeInfo *)treeNodeInfo { // create and configure cell for *item* return cell } ``` ```objc - (id)treeView:(RATreeView *)treeView child:(NSInteger)index ofItem:(id)item { return @(index); } ``` ###Adding Pull to Refresh control Adding pull to refresh gesture is really easy using `RATreeView` and standard `UIRefreshControl` control. [![](https://raw.github.com/Augustyniak/RATreeView/master/Screens/PullToRefresh.png)](https://raw.github.com/Augustyniak/RATreeView/master/Screens/PullToRefresh.png) ```objc UIRefreshControl *refreshControl = [UIRefreshControl new]; [refreshControl addTarget:self action:@selector(refreshControlChanged:) forControlEvents:UIControlEventValueChanged]; [treeView.scrollView addSubview:refreshControl]; ``` Documentation ----------------- Documentation is available on [CocoaPods](http://cocoadocs.org/docsets/RATreeView/2.1.2). TODO ----------------- - Better delegate callbacks in case of recursive collapse and expand operations. - Improved documentation. - Unit tests. - Re-order rows feature. Author ----------------- RATreeView was created by Rafał Augustyniak. You can find me on twitter ([@RaAugustyniak](https://twitter.com/RaAugustyniak)). Release Notes ----------------- Information about newer versions of the library can be found in the [releases section](https://github.com/Augustyniak/RATreeView/releases) of the repository. Version 1.0.2 - Fixed bug in select and deselect operations. - Fixed bug in recursive expand operation (via @Arrnas). Version 1.0.1 - Fixed bug in recursive expand operation. Version 1.0.0 - Improved performance. - Added recursive expand operation. It can be performed by using `expandRowForItem: expandChildren:withRowAnimation:` method. Default behavior is non recursive expand. - Added recursive collapse operation. It can be performed by using `collapseRowForItem: expandChildren:withRowAnimation:` method. Default behavior is non recursive collapse. - Fixed bug in `itemForRowAtPoint:` method when passed point isn't inside any cell. Version 0.9.2 - Fixed bug in `endUpdates` method. Version 0.9.1 - Fixed behaviour of treeView:willSelectRowForItem: delegate method. Version 0.9.0 - Added possiblity to change content of the RATreeView dynamically. Possible row operations: - additions - deletions - repositions - Added additional 'cell accessing' methods. - Removed `RATreeNodeInfo` class. - Added additional instance methods in RATreeView which substitute functionality provided by `RATreeNodeInfo` class. - Bug fixes.
