How do I create a multiline table cell in iOS?

Question

How can I get the second cell to expand to fit the text rather than scaling the text? Is there a built in way of doing this in iOS or will I have to come up with some home-cook

Answer 1

Unfortunately, you are going to have to implement this feature yourself. There are a variety of methods and callbacks you need to make use of to calculate the height of the rows and labels. If you need some help getting started, I can amend this answer to include some sample code. Otherwise, I'm sure there are some related questions here on SO or Google that can get you started. In summary, however:

• Determine the height of the row in the UITableViewDelegate method -tableView:heightForRowAtIndexPath:. You'll probably need to use the NSString UIKit Addition methods to calculate how tall your string will be with a given font size, etc. Return the proper height from this delegate method.
• Make sure your label (either in IB or configured programmatically) is set to use multiple lines. If you set numberOfLines to 0, the label will use as many lines as necessary.
• In your UITableViewDataSource implementation of -tableView:cellForRowAtIndexPath:, you'll need to use the same logic as before to determine the frame of your labels. Set the text you want, then change the frame so that the label is tall enough to just barely fit all the text.
