如何为UITableViewRowAction设置多行标题

Question

How can I split the title string of a UITableViewRowAction in two lines? ...like Apple has done it in their mail app (iPhone); swipe right in the email list and you'll see the action "Mark as Unread", written on two lines.

Thanks a lot!

Answer 1

I never received a response on the comment so I'll assume you tried it and it worked. Regardless, the answer is to simply add a newline character to your title string. The title of a UITableViewRowAction is multiline compat.

var buttonTest = UITableViewRowAction(style: UITableViewRowActionStyle.Default, 
    title: "Line1\nLine2", handler: { (action, indexPath) -> Void in

If you want to customize the edit actions beyond the scope of what Apple allows you could always write your own functions that do the same thing or even use a library such as THIS to accomplish the same thing. This is what we were doing before Apple released the action to the public.

Answer 2

you can use \\n to break the string into multiple lines.

   NSString *info = [NSString stringWithFormat:@"\n line 1  \n"
                  "line 2 \n"
                  "line 3\n"];

If you want to display the text in a label in multiple lines,you can use

    textLabel.numberOfLines = //your number;
