How does the iOS Reminders App allow word wrapping to the next line in the TableView?

Question

I am using the iOS Reminders App on my iPhone, and I was noticing that inside the tableview it allows you to enter text that can wrap around to a new line and continue entering text for a reminder. I notice that the height of the cell changes to accommodate the size of the reminder text supplied. My question is I know this could be done with a UILabel, but you can't edit and enter text in a UILabel can you? So it must be a UITextField, but I thought a UITextField didn't allow the words to wrap to a new line? I thought it just continued to shrink itself down on one line? So what am I missing here?

Answer 1

It most likely uses a UITextView which does allow multiple text lines. You can then change the height of the UITableViewCell when the text wraps to the next line by looking at the delegate methods of UITextView.

Answer 2

Have you tried UITextView, it does the auto wrapping for you, but to auto resize the table cell height, might have to use the textViewDelegate didReplaceString method.

// goes inside the UITextView didReplaceString method
// assumes expectedTextSize is a CGSize struct (like this CGSize expectedTextSize)
expectedTextSize = [myTextView.text sizeWithFont:[UIFont fontWithName:"Arial" size:12] constrainedToSize:CGSizeMake(200, 999999) lineBreakMode:UILineBreakModeWordWrap];

// then in your tableView:heightForRow: table view delegate method
return expectedTextSize.height;
