String 149 | id = item["id"] as? String 150 | pId = item["pid"] as? String 151 | label = item["name"] as? String 152 | 153 | node = TreeNode(desc: desc, id: id, pId: pId, name: label) 154 | nodes.append(node) 155 | } 156 | 157 | /** 158 | * 设置Node间，父子关系;让每两个节点都比较一次，即可设置其中的关系 159 | */ 160 | var n: TreeNode 161 | var m: TreeNode 162 | for (var i=0; i [TreeNode] { 189 | var root: [TreeNode] = [] 190 | for item in nodes { 191 | if item.isRoot() { 192 | root.append(item) 193 | } 194 | } 195 | return root 196 | } 197 | 198 | //把一个节点的所有子节点都挂上去 199 | func addNode(inout nodes: [TreeNode], node: TreeNode, defaultExpandLeval: Int, currentLevel: Int) { 200 | nodes.append(node) 201 | if defaultExpandLeval >= currentLevel { 202 | node.setExpand(true) 203 | } 204 | if node.isLeaf() { 205 | return 206 | } 207 | for (var i=0; i 0 { 215 | node.type = TreeNode.NODE_TYPE_G 216 | if node.isExpand { 217 | // 设置icon为向下的箭头 218 | node.icon = "tree_ex.png" 219 | } else if !node.isExpand { 220 | // 设置icon为向右的箭头 221 | node.icon = "tree_ec.png" 222 | } 223 | } else { 224 | node.type = TreeNode.NODE_TYPE_N 225 | } 226 | } 227 | } 228 | ``` 229 | 剩下的代码难度不大，很容易理解。需要多说一句的TreeNode.NODE\_TYPE\_G和TreeNode.NODE\_TYPE\_N是用来告诉TreeNode当前的节点的类型。正如上面提到的企业通讯录，这个两个type就可以用来区分node数据。 230 | 231 | TreeTableView我的重头戏来了。它继承了UITableView， UITableViewDataSource，UITableViewDelegate。 232 | 233 | ``` Swift 234 | func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 235 | // 通过nib自定义tableviewcell 236 | let nib = UINib(nibName: "TreeNodeTableViewCell", bundle: nil) 237 | tableView.registerNib(nib, forCellReuseIdentifier: NODE_CELL_ID) 238 | 239 | var cell = tableView.dequeueReusableCellWithIdentifier(NODE_CELL_ID) as! TreeNodeTableViewCell 240 | 241 | var node: TreeNode = mNodes![indexPath.row] 242 | 243 | //cell缩进 244 | cell.background.bounds.origin.x = -20.0 * CGFloat(node.getLevel()) 245 | 246 | //代码修改nodeIMG---UIImageView的显示模式. 247 | if node.type == TreeNode.NODE_TYPE_G { 248 | cell.nodeIMG.contentMode = UIViewContentMode.Center 249 | cell.nodeIMG.image = UIImage(named: node.icon!) 250 | } else { 251 | cell.nodeIMG.image = nil 252 | } 253 | 254 | cell.nodeName.text = node.name 255 | cell.nodeDesc.text = node.desc 256 | return cell 257 | } 258 | ``` 259 | tableView:cellForRowAtIndexPath方法中,我们使用了UINib，因为我通过自定义TableViewCell,来填充tableview。这里也使用了cell的复用机制。 260 | 261 | 下面我们来看控制树形结构展开的关键代码 262 | 263 | ``` 264 | func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 265 | var parentNode = mNodes![indexPath.row] 266 | 267 | var startPosition = indexPath.row+1 268 | var endPosition = startPosition 269 | 270 | if parentNode.isLeaf() {// 点击的节点为叶子节点 271 | // do something 272 | } else { 273 | expandOrCollapse(&endPosition, node: parentNode) 274 | mNodes = TreeNodeHelper.sharedInstance.filterVisibleNode(mAllNodes!) //更新可见节点 275 | 276 | //修正indexpath 277 | var indexPathArray :[NSIndexPath] = [] 278 | var tempIndexPath: NSIndexPath? 279 | for (var i = startPosition; i < endPosition ; i++) { 280 | tempIndexPath = NSIndexPath(forRow: i, inSection: 0) 281 | indexPathArray.append(tempIndexPath!) 282 | } 283 | 284 | // 插入和删除节点的动画 285 | if parentNode.isExpand { 286 | self.insertRowsAtIndexPaths(indexPathArray, withRowAnimation: UITableViewRowAnimation.None) 287 | } else { 288 | self.deleteRowsAtIndexPaths(indexPathArray, withRowAnimation: UITableViewRowAnimation.None) 289 | } 290 | //更新被选组节点 291 | self.reloadRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.None) 292 | 293 | } 294 | 295 | } 296 | 297 | //展开或者关闭某个节点 298 | func expandOrCollapse(inout count: Int, node: TreeNode) { 299 | if node.isExpand { //如果当前节点是开着的，需要关闭节点下的所有子节点 300 | closedChildNode(&count,node: node) 301 | } else { //如果节点是关着的，打开当前节点即可 302 | count += node.children.count 303 | node.setExpand(true) 304 | } 305 | 306 | } 307 | 308 | //关闭某个节点和该节点的所有子节点 309 | func closedChildNode(inout count:Int, node: TreeNode) { 310 | if node.isLeaf() { 311 | return 312 | } 313 | if node.isExpand { 314 | node.isExpand = false 315 | for item in node.children { //关闭子节点 316 | count++ // 计算子节点数加一 317 | closedChildNode(&count, node: item) 318 | } 319 | } 320 | } 321 | 322 | ``` 323 | 我们点击某一个非叶子节点的时候，将该节点的子节点添加到我们的tableView中，并给它们加上动画。这就是我们需要的树形展开视图。首先我们要计算出该节点的子节点数（在关闭节点的时候，还需要计算对应的子节点的子节点的展开节点数），然后获取这些子节点的集合，通过tableview的insertRowsAtIndexPaths和deleteRowsAtIndexPaths方法进行插入节点和删除节点。 324 | 325 | tableview:didSelectRowAtIndexPath还算好理解，关键是expandOrCollapse和closedChildNode方法。 326 | 327 | expandOrCollapse的作用是打开或者关闭点击节点。当操作为打开一个节点的时候，只需要设置该节点为展开，并且计算其子节点数就可以。而关闭一个节点就相对麻烦。因为我们要计算子节点是否是打开的，如果子节点是打开的，那么子节点的子节点的数也要计算进去。可能这里听起来有点绕口，建议运行程序后看着实例进行理解。 328 | 329 | ### 3、鸣谢 330 | 借鉴的资料有： 331 | 332 | * [swift 可展开可收缩的表视图](http://www.jianshu.com/p/706dcc4ccb2f) 333 | 334 | * [Android 打造任意层级树形控件 考验你的数据结构和设计](http://blog.csdn.net/lmj623565791/article/details/40212367) 335 | 336 | 有兴趣的朋友也可以参考以上两篇blog。 337 | 338 | ## License 339 | All source code is licensed under the MIT License. 340 | 341 | 342 | 343 | 344 | -------------------------------------------------------------------------------- /TreeTableVIewWithSwift.xcodeproj/project.pbxproj: -------------------------------------------------------------------------------- 1 | // !$*UTF8*$! 2 | { 3 | archiveVersion = 1;
