Hey,
Do you know how we could change the line height (not the frame height, like you have done here) of a UILabel? I’m looking at a UILabel with multiple lines.

Hi Smolinski, Rob Mathews

I worked for for “heightForRowAtIndexPath” of tableview.
You can take idea from here

Has someone worked through enabling functionality for “heightForRowAtIndexPath” using the current source code. If yes, please post the changes/updates that need to be made.

You don’t have to answer or show this or my latest reply. I’ve solved it myself, thanks for help!

My second week with this, sry.

But i guess that “value” is your label that you use later in your tableView?

But when i’m going to use my label in my switch as I describe earlier like this:

switch (indexPath.row) {
case 0: {
cell.value.text = myData;
} break;

I get the message: request for meber “value” in something not a structure or a union.?

I have added the method to a utils class but you can add it to your table view class or whatever. This is how I call the method in my TableCell class:

- (void)setValueAndCalculateHeight:(NSString *)text
{
self.value.text = text;

CGRect frame = value.frame;
frame.size.height = [MLUtils calculateHeightOfTextFromWidth:self.value.text :self.value.font :frame.size.width :self.value.lineBreakMode];

//If the new height is larger then min height we add the frame to description label
if(frame.size.height>VALUE_MIN_HEIGHT)
{
self.value.frame = frame;
}
}

So to set the text in the cell i pass it to my function which will call the static calculateHeightOfTextFromWidth method in my MLUtils class. The height is used to adjust the frame of the cell. Hope this helps. Good luck!
