Print arrays to label?

Hi, I'm trying to learn about arrays, and put them to use in a simple app I'm playing around with. I have a array, and want to display all the content of that array in a UILabel. But I can't get it to work. Is there a video here on Treehouse that includes this part in an actual app? Or can someone help me out with this?

-Thanks

Hi Stian,

This very much depends on the type of objects in the array. If it is the standard types e.g. String, Int etc. You can use String interpolation to get the string representation of the array and assign that to the labels text property.

textLabel.text = "\(array)"

However, if its array of custom objects its a bit more tricky to get a proper String representation as it involves protocols which is a bit further down the track.

Hope that helps

Ian
