RATreeView is a class designed to provide easy and pleasant way to work with tree views on iOS and tvOS. 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)
```objc
UIRefreshControl *refreshControl = [UIRefreshControl new];
[refreshControl addTarget:self action:@selector(refreshControlChanged:) forControlEvents:UIControlEventValueChanged];
[treeView.scrollView addSubview:refreshControl];
```
