Question

I’m trying to store numbers in a NSMutableArray, but when I check it, all I get is garbage.

-(void)storeIntoArray:(int)indexInt
{
    NSNumber *indexNum = [[NSNumber alloc] initWithInt:indexInt];
    [last100 insertObject:indexNum atIndex:prevCount];
    prevCount++;

    if(prevCount > 100)
    {
        prevCount = 0;
        cycledOnce = YES;
    }

}

-(BOOL)checkArray:(int)indexInt
{
for(int i = 0;i < [last100 count];i++)
    {
        NSLog(@"Stored: %d",[last100 objectAtIndex:i]);
        if (indexInt == (int)[last100 objectAtIndex:i]) {
            NSLog(@"Same entry, trying again");
            return YES;
        }
    }
    return NO;
}

When I check, I’ll get values back like Stored: 110577680 and just various garbage values.

You’re printing the NSNumber object address, not its value. Try using intValue. Or, if you want to print the object directly, use %@ rather than %d.
