iOS Help with highscore

[drf1229]

For my next app update I want to add a highscore. The code bit I have for saving the score is as follows:

NSArray *paths = NSSearchPathForDirectoriesInDomains
		(NSDocumentDirectory, NSUserDomainMask, YES);
		NSString *documentsDirectory = [paths objectAtIndex:0];
		NSString *fullFileName = [NSString stringWithFormat:@"%@/highscore", documentsDirectory];
		NSMutableArray *array = [[NSMutableArray alloc] initWithContentsOfFile:fullFileName];
		NSString *score=[array objectAtIndex:0];
		[time2 setText:score];
		int score2=[[time2 text] intValue];
		if (points>score2){
//Points is the 
//amount of points 
//just scored			
NSMutableArray *array2=array;
			[array2 removeObjectAtIndex:0];
			[array2 insertObject:[NSString stringWithFormat:@"%i",points] atIndex:0];
			printf("High score beat! New score is:%i Old score was:%i",points,score2);
			
			[array2 writeToFile:fullFileName atomically:NO];
			
		}

For some odd reason score2 always returns 0, yet [time2 text] is the correct score. I am completely baffled. Am I misusing "intvalue"? Any help or advice would be greatly appreciated! Edit: I recently looked at the NSString class reference provided by apple, and it said intvalue "Returns 0 if the receiver doesn’t begin with a valid decimal text representation of a number". I think this means that if the string doesn't start with a number it won't work, but that doesn't make sense because the value I wrote to the file does start with a number.

I don't have an iPhone but that looks like an awesome start! Get this done and make a Paid app and make some money! : )

I can't remember if i had an issue with this or not. Is it possible there is extra whitespace in the stored string. I cant remember if it automatically trims it or if this could cause an issue.

You might want to look into extra white space causing an issue.

Oh I see I fixed it thanks!

I really would like to see more folks post their final solutions rather than this type of end response.

Ok... I put an if statement to make sure that the file I was reading wasn't blank:

NSArray *paths = NSSearchPathForDirectoriesInDomains
	(NSDocumentDirectory, NSUserDomainMask, YES);
	NSString *documentsDirectory = [paths objectAtIndex:0];
	NSString *fullFileName = [NSString stringWithFormat:@"%@/practice", documentsDirectory];
	NSMutableArray *array = [[NSMutableArray alloc] initWithContentsOfFile:fullFileName];
if([array objectAtIndex:0]!=0){

//Read from the file

}
else{

//Write default data to the file

}
