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;
}
