從indexPathsForSelectedRows（）中提取數據 - SWIFT

Question

我試圖從表中選定的行提取所有數據。我使用下面的代碼來打印indexPaths。但是，我需要做些什麼才能打印出選定行中的文本？

 let indexPaths:NSArray = tableView.indexPathsForSelectedRows()! 


      `for var i = 0; i < indexPaths.count; ++i { 

      var thisPath:NSIndexPath = indexPaths.objectAtIndex(i) as NSIndexPath 

      println("row = \(thisPath.row) and section = \(thisPath.section)") 
     } 

打印到控制檯所選行

row = 1 and section = 0 
row = 3 and section = 0 

row = 6 and section = 0

Answer 1

可以使用的UITableView的cellForRowAtIndexPath方法通過索引路徑以獲得細胞：

if let indexPaths = tableView.indexPathsForSelectedRows() { 
    for var i = 0; i < indexPaths.count; ++i { 

     var thisPath = indexPaths[i] as NSIndexPath 
     var cell = tableView.cellForRowAtIndexPath(thisPath) 
     if let cell = cell { 
      // Do something with the cell 
      // If it's a custom cell, downcast to the proper type 
     } 
    } 
} 

注意indexPathsForSelectedRows返回一個可選項（無沒有行被選中），所以最好用可選的綁定來保護它以防止運行時異常。
