That special case does start adding it, but it shows me that the code
doesn't do what I inteded to do.
With this code below I expected this output:
("The Arcade Fire", "Neon Bible", None, Indie, 2007, 254, 1,
"The Arcade Fire", Funeral, None, Indie, 2004, 2840, 10)
but instead it is listing every track and adding as it goes.
("The Arcade Fire", "Neon Bible", None, Indie, 2007, 254, 1,
"The Arcade Fire", Funeral, None, Indie, 2004, 240, 1)
"The Arcade Fire", Funeral, None, Indie, 2004, 480, 2)
"The Arcade Fire", Funeral, None, Indie, 2004, 840, 3)
...
"The Arcade Fire", Funeral, None, Indie, 2004, 2840, 10)
The Code:
NSString *cur_artist = [[allTapes objectAtIndex:0]
objectAtIndex:0];
NSString *cur_venue = [[allTapes objectAtIndex:0]
objectAtIndex:1];
NSString *cur_location = [[allTapes objectAtIndex:0]
objectAtIndex:2];
NSString *cur_genre = [[allTapes objectAtIndex:0]
objectAtIndex:3];
NSString *cur_year = [[allTapes objectAtIndex:0]
objectAtIndex:4];
// NSString *cur_length = [[allTapes objectAtIndex:0]
objectAtIndex:5];
int cur_length = 0;
int cur_count = 0;
NSMutableArray * tapeBunch = [[NSMutableArray alloc] init];
tapeBunch = [[tapeBunch retain] autorelease];
int allofthem = [allTapes count];
for(i = 0; i < allofthem; i++){
NSComparisonResult artistResult, venueResult;
artistResult = [[[allTapes objectAtIndex:i] objectAtIndex:0]
compare:cur_artist];
venueResult = [[[allTapes objectAtIndex:i] objectAtIndex:1]
compare:cur_venue];
if(artistResult != NSOrderedSame || venueResult !=
NSOrderedSame ||
i == 0){
cur_artist = [[allTapes objectAtIndex:i]
objectAtIndex:0];
cur_venue = [[allTapes objectAtIndex:i]
objectAtIndex:1];
cur_location = [[allTapes objectAtIndex:i]
objectAtIndex:2];
cur_genre = [[allTapes objectAtIndex:i]
objectAtIndex:3];
cur_year = [[allTapes objectAtIndex:i]
objectAtIndex:4];
cur_length = [[[allTapes objectAtIndex:i]
objectAtIndex:5] intValue];
cur_count = 1;
}
else{
cur_count++;
cur_length += [[[allTapes objectAtIndex:i]
objectAtIndex:5] intValue];
}
[tapeBunch addObject:cur_artist];
[tapeBunch addObject:cur_venue];
[tapeBunch addObject:cur_location];
[tapeBunch addObject:cur_genre];
[tapeBunch addObject:cur_year];
[tapeBunch addObject:[NSString stringWithFormat:@"%i",
cur_length]];
[tapeBunch addObject:[NSString stringWithFormat:@"%i",
cur_count]];
}
NSLog(@"tapeBunch:\n %@", tapeBunch);
