How to change text of a SKLabelNode?

Question

How do I update a label's text that was created in initWithSize? Here is the code for the label within the initWithSize:

SKLabelNode *scoreLabel = [SKLabelNode labelNodeWithFontNamed:@"TimesNewRoman"];
    scoreLabel.text = [NSString stringWithFormat:@"%i", score];
    scoreLabel.fontSize = 30;
    scoreLabel.position = CGPointMake(290, CGRectGetMidY(self.frame) - 30);
    scoreLabel.zRotation = -M_PI/2;
    [self addChild:scoreLabel];

As the game is running I update the variable score and I was just wondering how I can get the label to display the new score.

Answer 1

You will have to declare scoreLabel in the header file and then just so scoreLabel.text = //Your text anywhere you want.

EDIT:

In your .h file, declare @property (nonatomic,strong) SKLabelNode *scoreLabel;

In your .m file, add @synthesize scoreLabel;

When you are initializing the label do

self.scoreLabel = [SKLabelNode labelNodeWithFontNamed:@"TimesNewRoman"];

and not

SKLabelNode *scoreLabel = [SKLabelNode labelNodeWithFontNamed:@"TimesNewRoman"];

Answer 2

Set retain/strong property for your SKLabelNode. then call any where from your app just

@Property(nonatomic,retain)SKLabelNode *scoreLabel;

if your score value has string

self.scoreLabel.Text=yourscore

if it is integer

self.scoreLabel.Text=[NSString stringWithFormat:@"%d", [yourscore intValue]]];
