当用户在UITextview

Question

当用户在UITextview中输入一些文本并且我将左，右，底部和上部间距5px约束到UItextView时，我应该完全混淆我应该在运行时增加tableview单元格高度。我在屏幕上显示但我不使用任何自定义tableviewcell课程。我想在单个控制器中执行此任务。我只使用XCode 7.3和我的swift版本2.0

 @IBOutlet var tedxtviewtableview: UITableView!
  var record : NSArray = NSArray()
  var  hight: CGFloat = 0.0
  var newtextstring : NSString = NSString()

我的静态数组。

 record = ["I have a UITextView in a custom UITableViewCell. The textview delegate is assigned in the tableviewcell custom class." ,"Textview scrolling is disabled. Text loads into each textview and is multiline. But the text is always clipped because the cell height doesn't change.","I have the following in viewDidLoad of the tableview controller:"," have a UITextView in a custom UITableViewCell. The textview delegate is assigned in the tableviewcell custom class.","Textview scrolling is disabled. Text loads into each textview and is multiline. But the text is always clipped because the cell height doesn't change.","I have the following in viewDidLoad of the tableview controller:","i just give you one link at put place i use label and you can now use your textview and give same constrain that i give in that link and try it so your problem will be solve","I have the following in viewDidLoad of the tableview controller:"];

// tableview delegates method

 func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return record.count
 }

 func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
       let cell = tableView.dequeueReusableCellWithIdentifier("Textviewcell", forIndexPath: indexPath)
       let textview: UITextView = (cell.viewWithTag(5) as! UITextView)
       textview.scrollEnabled = false
       textview.text = record.objectAtIndex(indexPath.row) as? String
       Textchange = false
       return cell

}
func textViewDidChange(textView: UITextView , Nsindex : NSIndexPath) {
        newtextstring = textView.text
        self.tedxtviewtableview.beginUpdates()

        Textchange = true

}

        // 7.1>
        if Textchange == true {

            return 44 + hight
        }
   }

 func findHeightForText(text: String, havingWidth widthValue: CGFloat, andFont font: UIFont) -> CGSize {

    var size = CGSizeZero
    if text.isEmpty == false {
    let frame = text.boundingRectWithSize(CGSizeMake(widthValue, CGFloat.max), options: .UsesLineFragmentOrigin, attributes: [NSFontAttributeName: font], context: nil)
        size = CGSizeMake(frame.size.width, ceil(frame.size.height))
     }
     return size
    }

Answer 1

取一个变量

 var indexPath1 : NSIndexPath = NSIndexPath()

只需在代码中更改此内容

即可

func textViewDidChange(textView: UITextView){

        let textFieldRowCell = (textView.superview!.superview! as! UITableViewCell)
         indexPath1 = self.tedxtviewtableview.indexPathForCell(textFieldRowCell)! //self.tedxtviewtableview.indexPath(forCell: textFieldRowCell)!

        newtextstring = textView.text
       self.tedxtviewtableview.beginUpdates()

        // This will cause an animated update of
        //Textchange = true
        self.tableView(self.tedxtviewtableview, heightForRowAtIndexPath: indexPath1)
       self.tedxtviewtableview.endUpdates()

    }

func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
        // 7.1>
        if indexPath == indexPath1 {
              hight = self.findHeightForText(newtextstring as String, havingWidth: self.view.frame.size.width - 10, andFont: UIFont.systemFontOfSize(14.0)).height
            return 44 + hight
        }else{
            hight = self.findHeightForText(self.record.objectAtIndex(indexPath.row) as! String, havingWidth: self.view.frame.size.width - 10, andFont: UIFont.systemFontOfSize(14.0)).height
            return 44 + hight
        }
   }

希望它能运作
