Sometimes you need to put a number value in a text field. To do that, you'll need to convert the number to a string. See how the process works in this video.
- [Instructor] So we've looked at putting a string value…inside of a label.…So we can take a string value and put it right in there,…but what if you're making a game,…an in the game the user has a score,…and you want the label to display the player's score.…The thing is, the score is not a string, it's an integer.…It's a number.…So how do we get a number value and convert it…into a string value?…We can do that by going into viewDidLoad.…
And what I'm going to do is create a variable inside of here.…So instead of creating it up here outside of viewDidLoad…and making an instance variable, I'm going to create…what is called a local variable inside viewDidLoad.…A variable declared inside of a method…inside of these curly braces right here is only known…to that method.…So for example, if I wanted to access this label…that I've created here on line 12, I can reference it…inside of a method.…
I can reference it in viewDidLoad like we've done here.…I can also reference it inside didReceiveMemoryWarning.…As I start to type it, you can see the code hinting…
