addObject to NSMutableArray not working

Question

In short, I want my tableView to show events (eg. football matches) that are happening Today. Therefore, I want to add those dictionaries that match to a NSMutableArray by use of addObject. I've tried it with this code, but the NSMutableArray does not show anything:

self.Array = [NSMutableArray arrayWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"matches" ofType:@"plist"]];

matchesToday = [[NSMutableArray alloc] init];
match = [[NSMutableDictionary alloc] init];

for  (int i=0; i<[Array count]; i++) {
        NSDate *datum = [[Array objectAtIndex:i] objectForKey:@"date"];
        NSCalendar *cal = [NSCalendar currentCalendar];
        NSDateComponents *components = [cal components:(NSEraCalendarUnit|NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit) fromDate:[NSDate date]];
        NSDate *today = [cal dateFromComponents:components];
        components = [cal components:(NSEraCalendarUnit|NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit) fromDate:datum];
        NSDate *otherDate = [cal dateFromComponents:components];

        if([today isEqualToDate:otherDate]) {

            //do stuff
            [matchesToday addObject:match];

        NSLog(@"%i, %@", i, otherDate);
        NSLog(@"Match is today");

    }
    else {
        NSLog(@"Match is not today");
    }
    }
NSLog(@"%@", matchesToday);
}

The plist is an array of dictionaries that looks like this:

<array>
    <dict>
    <key>date</key>
    <date>2011-12-13T00:00:00Z</date>
    <key>titel</key>
    <string>Tilburg - Oss</string>
    </dict>
    <dict>
    <key>date</key>
    <date>2011-12-13T00:00:00Z</date>
    <key>titel</key>
    <string>Amsterdam - Roosendaal</string>
    </dict> 
</array>

What am I doing wrong?

In your code, match is nothing but an empty dictionary. You don't do anything with your match dictionary at any point after you alloc and init it. If it's in the // do something comment block, please add that. — Tim

No, I haven't done anything with 'match' indeed. I want 'match' to correspond to the dictionaries from the plist. This must be the problem. I guess I should do something like NSMutableArray *match = [Array..... Any thoughts? — user1048042

You need to be adding the individual item from Array inside the date test if statement with the following line:

[matchesToday addObject:[Array objectAtIndex:i]];

At the point that this code executes, match is just an empty mutable array.
