Check NSMutableDictionary for values

I'm making an API Calls which contain live information. This can 2 types of information. If there is information it will return something like this:

goaltype = "Regular goal";
id = 2787821;
minute = 45;
player = Nono;
"player_id" = 317569;
playershort = Nono;
team = "Real Betis";
"team_id" = 8603;

If there is no information it will return:

error = "no live games found"

If it returns error my tableview will at the moment count the error message as 1 object and return 1 cell. So if the results return error, then it should not run the loop. How can i obtain this or is there another way?

my code:

NSDictionary* headers = @{@"X-Mashape-Authorization": @"MASHAPEKEY"};
NSDictionary* parameters = @{};

UNIHTTPJsonResponse* response = [[UNIRest get:^(UNISimpleRequest* request) {
    [request setUrl:@"https://willjw-statsfc-competitions.p.mashape.com/live.json?key=APIKEY&competition=premier-league&timezone=Europe%2FLondon"];

    [request setHeaders:headers];
    [request setParameters:parameters];
}] asJson];


NSData* rawBody = [response rawBody];
results = [NSJSONSerialization JSONObjectWithData:rawBody options:NSJSONReadingMutableContainers error:nil];




for (int i = 0; i <= results.count-1; i++)
{


    NSString *homeTeam = [[results valueForKey:@"homeshort"] objectAtIndex:i ];
    NSString *awayTeam = [[results valueForKey:@"awayshort"] objectAtIndex:i ];
    NSString *time = [[results valueForKey:@"statusshort"] objectAtIndex:i ];
    NSString *homeScore = [NSString stringWithFormat:@"%@", [[[results valueForKey:@"runningscore"] objectAtIndex:i ] objectAtIndex:0]];
    NSString *awayScore = [NSString stringWithFormat:@"%@", [[[results valueForKey:@"runningscore"] objectAtIndex:i ] objectAtIndex:1]];


    [arrayBarclay addObject:[[NSMutableDictionary alloc] initWithObjectsAndKeys:homeTeam,@"hometeam", awayTeam,@"awayteam", time, @"time", homeScore, @"homescore", awayScore, @"awayscore", nil]];

}

What NeverHopeless said… plus… (much simpler syntax)

if (![result valueForKey:@"error"]) {
    for (int i = 0; i < results.count; i++) {
        NSString *homeTeam = results[@"home short"][i];
        NSString *awayTeam = results[@"awayshort"][i];
        NSString *time = results[@"statusshort"][i];
        NSString *homeScore = [NSString stringWithFormat:@"%@", results[@"runningscore"][i][0];
        NSString *awayScore = [NSString stringWithFormat:@"%@", results[@"runningscore"][i][1];
        [arrayBarclay addObject:[NSMutableDictionary dictionaryWithDictionary:@[
            @"hometeam":homeTeam, 
            @"awayteam":awayTeam,
            @"time":time,
            @"homescore":homeScore,
            @"awayscore":awayScore]
        ];
    }
}

(I would have posted this as a comment on NeverHopeless's answer except that comments lose formatting.)

If no sight of error key that means you are getting expected data, so iterating on resultset is expected to be safe.

if(![result valueForKey:@"error"])
{
for (int i = 0; i <= results.count-1; i++)
{


    NSString *homeTeam = [[results valueForKey:@"homeshort"] objectAtIndex:i ];
    NSString *awayTeam = [[results valueForKey:@"awayshort"] objectAtIndex:i ];
    NSString *time = [[results valueForKey:@"statusshort"] objectAtIndex:i ];
    NSString *homeScore = [NSString stringWithFormat:@"%@", [[[results valueForKey:@"runningscore"] objectAtIndex:i ] objectAtIndex:0]];
    NSString *awayScore = [NSString stringWithFormat:@"%@", [[[results valueForKey:@"runningscore"] objectAtIndex:i ] objectAtIndex:1]];


    [arrayBarclay addObject:[[NSMutableDictionary alloc] initWithObjectsAndKeys:homeTeam,@"hometeam", awayTeam,@"awayteam", time, @"time", homeScore, @"homescore", awayScore, @"awayscore", nil]];

}
}
