I have a view and table view design using Autolayout and Constraints. I have successfully design view using Autolayout.
But I have one more requirement in table view cell content. ** I want to increase LABEL height accordingly text (Depend on content of label text- Label 1). Please review attached screen shot. I have set CELL into the table view using Storyboard. Table view cell into I have taken 3 Labels.**
Label -2 : I have set constraint label-2, Leading edge constraint-5, Trailing edge constraint-5, Top edge constraint-10, Bottom constraint-0. Here I set height of Label-2 20. It fixed and I do not want to increase them.
Label -3 : I have set constraint label-3, Leading edge constraint-5, Trailing edge constraint-5, Top edge constraint-0, Bottom constraint-5. Here I set height of Label-3 20. It fixed and I do not want to increase them.
I want to increase height of Label 1 according to text.
**_Label -1 :_** I want to increase size of Label 1. I have set constraint label-1, Leading edge constraint-5, Trailing edge constraint-5, Top edge constraint-5, Bottom constraint-10. Here I set height of Label-1 35.
Right now, I have not set constraint of Label-1 height constraint. I have also tried set height constraint but it’s cannot take effect on height increases issues. I have created method for Label-1. It was count label-1 size and increases it accordingly. But it was not return current height.
Here, I set table view cell size 95. And it will be increase dynamically using table view height delegate method.

Source Code :-_
UITableViewSource Method:
//Count Height of table view cell
public override nfloat GetHeightForRow (UITableView tableView, NSIndexPath indexPath){
TableViewCellClass cell = null;
cell = (TableViewCellClass)tableView.DequeueReusableCell(cellIdentifier);
return cell.RequiredTableViewCellHeight(tableView.Bounds.Size.Width);
}
public override UITableViewCell GetCell (UITableView tableView, NSIndexPath indexPath){
TableViewCellClass cell = (TableViewCellClass)tableView.DequeueReusableCell(cellIdentifier,indexPath);
//Add Data In Cell
cell.Updatecell (tableItems [indexPath.Row].Label1Data, tableItems [indexPath.Row].Label2Data, tableItems [indexPath.Row].Label3Data);
return cell;
}
TableView Cell Method:-
partial class TableViewCellClass : UITableViewCell{
public TableViewCellClass (IntPtr handle) : base (handle)
{
}
public void Updatecell (string lbl1Data, string lbl2Data, DateTime lbl3Data){
Label1.Text = lbl1Data; //I want to increases height of label1
Label2.Text = lbl2Data;
Label3.Text = lbl3Data.ToString();
//Here Below, fixed text and size for Label-2 and Label-3. It was fixed and never increase it's height
Label2.SizeToFit();
Label2.AdjustsFontSizeToFitWidth = true;
Label3.SizeToFit();
Label3.AdjustsFontSizeToFitWidth = true;
}
//RequiredTableViewCellHeight Method For Count Label Hight and Increase Cell According to it.
public float RequiredTableViewCellHeight(nfloat screenWidth){
Console.WriteLine("screenWidth : {0}",screenWidth); //Here we get the screen size of table view WIDTh
//Here make dynamic lable
Label1.Lines = 0;
Label1.AdjustsFontSizeToFitWidth = false;
UIFont cellFont = Label1.Font;
nfloat lbl1widthVal = screenWidth - 10; //Here we Minus 10 due to leading and trailing constraint. So Width not effected.
//Below Count the size of label height accordingly text and font size. Size not return actuall size. It's some time return always same.
CGSize lbl1Size = ((NSString) Label1.Text).StringSize(cellFont,constrainedToSize:new CGSize(lbl1widthVal,400.0f),lineBreakMode:UILineBreakMode.WordWrap);
Console.WriteLine("lbl1Size Total Size: {0}",lbl1Size);
int rowHeight = (int)lbl1Size.Height; //Get the Height of table cell
Console.WriteLine("rowHeight: {0}",rowHeight);
rowHeight += 60; //Add extra 60 due to label-2, label-3 size and spacing value in cell
Console.WriteLine("After Final Edit rowHeight value: {0}",rowHeight);
return (float)rowHeight;
}
}
Can i fetch issues due to autolayout or I do make mistake somewhere in code?
Please note that, I do not want to remove autolayout in project.
Please review that and let us know your suggestions. Thank in advance!
