For me this is worked

NSArray* merStore = [tmpDictn objectForKey:@"merchantStore"];

if ([merStore isKindOfClass:[NSArray class]] && merStore.count !=0)
{
    for(int n = 0; n < merStore.count; n++)
    {
        NSMutableDictionary *storeDic = [merStore objectAtIndex:n];


        [latitudeArray addObject:[storeDic objectForKey:@"latitude"]];

    }
}

I hope it helps some one. If you need any help let me know.
