Making text = an int (cocos2d iPhone)

I have an int named percentComplete (for a SplashScene). I need to make that into text (CCLabelBMFont) that will have the same number as the int, and be updated when the int is. Think of a loading screen that has a number represent how far it is until the game can start (77%). I've started with this so far. I end up with a warning. percentComplete is the int, percentCompleteText is a CCLabelBMFont

    -(void)displayPercentCompleteText:(id)sender {
    percentCompleteText = (CCLabelBMFont *) [self getChildByTag:kTagPercentComplete];
    [percentCompleteText setString:[percentComplete getPercentComplet开发者_高级运维eAsString]]; //Invalid receiver type 'int'
    percentCompleteText.position = ccp(111, 111); //CHANGE POSITION
    //SCHEDULE UPDATE EVERY .01s
}   

    -(NSString *)getPercentCompleteAsString {
        return [NSString stringWithFormat:@"%d", percentComplete];
    }

I'm assuming -(NSString *)getPercentCompleteAsString is in the same class as -(void)displayPercentCompleteText:(id)sender and percentComplete is a member variable (ivar) of that class ..

Change the line:

[percentCompleteText setString:[percentComplete getPercentCompleteAsString]]

to:

[percentCompleteText setString:[self getPercentCompleteAsString]]

 return [NSString stringWithFormat:@"%d", percentComplete];

what if you change the line to

return [NSString stringWithFormat:@"%i", percentComplete];

instead of double..
