I have created a couple of different UITableViewCell s for my tableViewController , this

  • 0

I have created a couple of different UITableViewCells for my tableViewController, this is because I have different bits of data I want to display depending what comes back. Because of this each UITableViewCell is of a different height.

This is all fine, However one of my UILabels has to display a large NSString, so large that I have had to word wrap it onto a second line, The only issue here is that it messes up my UITableViewCell formatting.

My question is, is it possible to flag or capture some type of action when a UILabel receiving a NSString has to use wordrap because the size of the NSString is too long?

Or is there a way to calculate the physical length (not how many chars are in the string) of the NSString so I can decide hey I need to reformat my UITableViewCell..

Any help would be greatly appreciated.

    The usual way is to use sizeWithFont:constrainedToSize:lineBreakMode: to get the size of a string. You use it like this:

    CGSize stringSize = [theString sizeWithFont:[UIFont fontWithName:@"Helvetica Neue" size:12] constrainedToSize:CGSizeMake(320, 3000) lineBreakMode:NSLineBreakByWordWrapping ];

    This is set for the full width of a table cell, but you would want to use the width of your label instead.
