Swift 'text' is unavailable: APIs deprecated as of iOS7. textLabel does not work

问题

I keep having this error

I've seen other questions been answered by using textLabel.text, but it doesn't work in my case

I'm new to swift so could someone please explain me why and how to solve this.

回答1:

You need to unwrap textLabel by using an ! after textLabel.

This is because textLabel is an Optional (hence the textLabel? type instead of just textLabel). Read more about optionals here.

Hope that helps!
