49 | 50 | ``` 51 | #### 2、设置代理 52 | ``` 53 | @protocol NodeTreeViewDelegate 54 | @required 55 | /** 56 | 返回对应节点下的视图：视图可以遵循NodeViewProtocol协议，让view具有一些统一的行为> 57 | 一种node对应一种nodeView 58 | 59 | @param node node节点 60 | @return node视图 61 | */ 62 | - (id_Nonnull)nodeTreeView:(NodeTreeView *_Nonnull)treeView viewForNode:(id_Nonnull)node; 63 | 64 | @optional 65 | 66 | /** 67 | 返回对应级别下的缩进 68 | 69 | @param treeView treeView 70 | @param nodeLevel 对应的nodeLevel 71 | @return 该level下对应的缩进 72 | */ 73 | - (CGFloat)nodeTreeView:(NodeTreeView *_Nonnull)treeView indentAtNodeLevel:(NSInteger)nodeLevel; 74 | /** 75 | 点击事件回调 76 | 77 | @param treeView 树 78 | @param node 节点模型 79 | */ 80 | - (void)nodeTreeView:(NodeTreeView *_Nonnull)treeView didSelectNode:(id_Nonnull)node; 81 | 82 | @end 83 | 84 | ``` 85 | #### 3、设置是否需要自动刷新，不建议使用自动刷新 86 | ``` 87 | /** 88 | 树的刷新策略 89 | 默认是手动刷新：NodeTreeRefreshPolicyManaul 90 | */ 91 | @property (nonatomic, assign) NodeTreeRefreshPolicy refreshPolicy; 92 | 93 | ``` 94 | #### 4、如果数据是实时获得的，那么需要手动调用刷新方法 95 | ``` 96 | /** 97 | 刷新node节点对应的树 98 | */ 99 | - (void)reloadTreeViewWithNode:(id_Nonnull)node; 100 | 101 | /** 102 | 刷新node节点对应的树，可以指定动画展开的方式 103 | @param node node节点 104 | */ 105 | - (void)reloadTreeViewWithNode:(id_Nonnull)node 106 | RowAnimation:(UITableViewRowAnimation)animation; 107 | 108 | ``` 109 | #### 5、使用时建议将treeView作为一个cell,放在一个tableview中使用。 110 | 111 | #### 6、关于`NodeModelProtocol`节点模型协议 112 | * 声明了一些遵守该协议的模型需要手动实现的属性和方法。 113 | * 属性声明：节点高度、子节点数组、父节点、节点所在的层级、节点展开后的所有儿子节点的高度之和、该节点所在树的当前整体高度、节点是否展开。 114 | * 方法声明：增加节点、从数组中增加节点、删除节点。 115 | 116 | #### 7、关于`NodeViewProtocol`节点模型协议 117 | * 定义了所有节点视图必须实现的方法,如下所示： 118 | ``` 119 | 120 | @protocol NodeViewProtocol 121 | @required 122 | /** 123 | 更新单个Node行 124 | 125 | @param node node模型 126 | */ 127 | - (void)updateNodeViewWithNodeModel:(id)node; 128 | /** 129 | 需要在该方法中，对cell进行重新布局，为了处理在缩进的时候宽度变化造成的影响 130 | */ 131 | - (void)layoutSubviews; 132 | 133 | @end 134 | ``` 135 | 136 | ## 三、对递归的使用 137 | 138 | 在处理树的时候，用到的一些递归操作： 139 | 140 | ``` 141 | ==================== NodeTreeView.m中对递归的使用 ==================== 142 | 1、#pragma mark NodeTreeViewStyleExpansion模式下，初始化数据源，递归的将所有需要展开的节点，加入到初始数据源中 143 | 144 | static inline void RecursiveInitializeAllNodesWithRootNode(NSMutableArray *allNodes,idrootNode){ 145 | if (rootNode.expand == NO || rootNode.subNodes.count == 0) { 146 | return;
