how to get the correct size of NSString or check Whether it would fit in UILabel or Not?

I have an UILabel that can display only three lines of Text and its height and width are (312,44) inside an UITableViewCell what do I want to do that if UILabel text is more or getting ... (dot, dot) Then display the text on Alert view when user long press on that particular cell inside UITableView.

enter image description here

But the problem I am facing if text is doted inside the label it calculates NSString size less than UILabel size in the below code. I am frustrating whats going wrong with it.

Here is UILabel inside UITableView

enter image description here

When I set "Breakpoint" in the code I am getting the size for the below string is (309.46,42.97) that is less than lblSize

        UILabel* lbl=(UILabel*)longPressGesture.view;
        CGSize size = [lbl.text sizeWithFont:lbl.font constrainedToSize:lbl.bounds.size lineBreakMode:lbl.lineBreakMode];
        CGSize lblSize=lbl.bounds.size;
        if (size.height> lblSize.height && size.width>lblSize.width)
        {
            UIAlertView* alertView=[[UIAlertView alloc]initWithTitle:@"Detail View" message:lbl.text delegate:nil cancelButtonTitle:@"Close" otherButtonTitles:nil, nil];

            [alertView show];
        }
    }

The problem is that you are asking for a size that fits the CURRENT label. You should ask for a size that fits a much taller label. So instead of

CGSize size = [lbl.text sizeWithFont:lbl.font constrainedToSize:lbl.bounds.size lineBreakMode:lbl.lineBreakMode];

you should use:

CGSize size = [lbl.text sizeWithFont:lbl.font constrainedToSize:CGSizeMake(lbl.bounds.size.width, 1000) lineBreakMode:lbl.lineBreakMode];
