DatePicker在Swift中調用didSelectRowATIndexPath

Question

DatePicker如何在TableView中單擊某個特定單元格時出現。此外，我需要一個完成按鈕在你TableViewController使用

Answer 1

後diasapper的DatePicker：

 var chosenNumber = 0 

     override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 
      //set your chosenNumber here based on your the cell that was clicked 
      chosenNumber = 1 
     } 

     override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject!) { 

      let controller = segue.destinationViewController as! ViewController 
      //the startRow variable in the ViewController with the picker is set to the same value as the chosenNumber 
      controller.startRow = chosenNumber 

     } 

與拾取您的ViewController

：

 var startRow = 0 
     override func viewDidLoad() { 
      //the selected item in the spinner will the value of startRow 
      spinner.selectRow(startRow, inComponent: 0, animated: false) 

     } 

隱藏微調一個按鈕被點擊時：

 @IBAction func buttonClicked(sender: UIButton) { 
      spinner.hidden = true 
     }
