Usage 使用方法

Check out the demo for example usage of library. Make sure you read the RATreeView documentation on Cocoa Docs.

Basics

1. Add following import in file of your project when you want to use RATreeView:

   // In case you are using RATreeView with CocoaPods
   #import <RATreeView.h>

   // 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:

   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:

   - (NSInteger)treeView:(RATreeView *)treeView numberOfChildrenOfItem:(id)item
   {
       return item ? 3 : 0;
   }

- (UITableViewCell *)treeView:(RATreeView *)treeView cellForItem:(id)item treeNodeInfo:(RATreeNodeInfo *)treeNodeInfo
{
   // create and configure cell for *item*
   return cell
}

- (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.

UIRefreshControl *refreshControl = [UIRefreshControl new];
[refreshControl addTarget:self action:@selector(refreshControlChanged:) forControlEvents:UIControlEventValueChanged];
[treeView.scrollView addSubview:refreshControl];
