NSString stringWithFormat "implicit conversion loses integer precision"

Im trying to save a high score using 

 HighScore = [[NSUserDefaults standardUserDefaults]integerForKey:@"ScoreSaved"];
 Intro3.text = [NSString stringWithFormat:@"HighScore: %i", HighScore];

it says :

"implicit conversion loses integer precision, NSInterger(aka long) to int

-(void)EndGame
{

if (ScoreNumber > HighScore){
    HighScore = ScoreNumber;
    [[NSUserDefaults standardUserDefaults]setInteger:HighScore forKey:@"ScoreSaved"];
}

this is my first game and i am stuck how would i save a high score? thank you for taking the time to read this.

You are using the wrong specifier with stringWithFormat, however getting the right one is difficult if you want to support both 32- and 64-bit targets. It's often easier to use %ld and cast the value to long:

Intro3.text = [NSString stringWithFormat:@"HighScore: %ld", (long)HighScore];

You use a wrong format specifier in your string formatting which causes an imporper conversion for the HighScore variable (NSInteger).

Use the %ld specifier which is intended for NSInteger types :

Intro3.text = [NSString stringWithFormat:@"HighScore: %ld", HighScore];
