树形结构视图，数据源无顺序要求，自动构建树结构。

支持多选单选，支持改各种颜色。

使用示例：

- (void)viewDidLoad {

[super viewDidLoad];

self.view.backgroundColor=[UIColor lightGrayColor];

// Do any additional setup after loading the view, typically from a nib.

self.treeView=[[YPTreeView alloc]initWithFrame:CGRectMake(0, 40,self.view.frame.size.width, self.view.frame.size.height-80)];

//支持多选

self.treeView.isCanMultipleChoice=YES;

self.treeView.delegate=self;

self.treeView.lineColor=[UIColor blackColor];

self.treeView.textColor=[UIColor blackColor];

self.treeView.backgroundColor=[UIColor colorWithRed:242/255.0 green:249/255.0 blue:255/255.0 alpha:1];

[self.view addSubview:self.treeView];

//可以异步 接口返回数据后赋值

self.treeView.dataArray=[self getDataArray];

}

其使用的数据源需要为NSArray<YPTreeNode>

数据例子：

-(NSArray *)getDataArray{

NSMutableArray * threeDataSoure=[NSMutableArray array];

YPTreeNode *treedata=[[YPTreeNode alloc]init];

treedata.name=@"根节点";

treedata.treeId=@"1";

treedata.parentId=@"0";

treedata.value=@"root";

treedata.isOpen=YES;

[threeDataSoure addObject:treedata];

YPTreeNode *treedata2=[[YPTreeNode alloc]init];

treedata2.name=@"第一章";

treedata2.treeId=@"3";

treedata2.parentId=@"1";

treedata2.value=@"first";

treedata2.isOpen=YES;

[threeDataSoure addObject:treedata2];

YPTreeNode *treedata3=[[YPTreeNode alloc]init];

treedata3.name=@"第二章";

treedata3.treeId=@"2";

treedata3.parentId=@"1";

treedata3.value=@"second";

treedata3.isOpen=YES;

[threeDataSoure addObject:treedata3];

YPTreeNode *treedata4=[[YPTreeNode alloc]init];

treedata4.name=@"第一节 iOS简介";

treedata4.treeId=@"5";

treedata4.parentId=@"3";

treedata4.value=@"second";

treedata4.isOpen=YES;

[threeDataSoure addObject:treedata4];

YPTreeNode *treedata5=[[YPTreeNode alloc]init];

treedata5.name=@"第一节 TableView的使用";

treedata5.treeId=@"4";

treedata5.parentId=@"2";

treedata5.value=@"TableView";

treedata5.isOpen=YES;

[threeDataSoure addObject:treedata5];

return threeDataSoure;

}
