Question

我有一个Parse类，它包含我在地图视图上每个注释所需的所有信息。我正在运行Parse查询来检索数据。我正在将数据添加到数组中，因为我正在使用数组来实现其他功能。我遇到的问题是，即使注释数组中包含我期望的注释数量，但我的地图上只显示了五个注释（98）。我做错了什么？

getMarkets方法（在viewDidLoad中调用）

- (void)getMarkets {
    self.lat = [[NSMutableArray alloc]init];
    self.lon = [[NSMutableArray alloc]init];
    self.title1 = [[NSMutableArray alloc]init];
    self.subtitle1 = [[NSMutableArray alloc]init];
    self.phoneNumbers = [[NSMutableArray alloc]init];
    self.websites = [[NSMutableArray alloc]init];
    marketLocations = [[NSMutableArray alloc]init];

    PFQuery *query = [PFQuery queryWithClassName:@"Markets"];
    [query setLimit:1000];
    [query orderByAscending:@"Name"];
    [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
        if (!error) {
            for (NSDictionary *objectDictionary in objects) {
                [self.title1 addObject:[objectDictionary objectForKey:@"CompanyName"]];
                [self.subtitle1 addObject:[objectDictionary objectForKey:@"MarketAddress"]];
                [self.phoneNumbers addObject:[objectDictionary objectForKey:@"MarketPhone"]];
                [self.websites addObject:[objectDictionary objectForKey:@"Website"]];
                [self.lat addObject:[objectDictionary objectForKey:@"Latitude"]];
                [self.lon addObject:[objectDictionary objectForKey:@"Longitude"]];

                marketAnnotation = [[FarmMarketAnnotation alloc]init];
                location.latitude = [[objectDictionary objectForKey:@"Latitude"]floatValue];
                location.longitude = [[objectDictionary objectForKey:@"Longitude"]floatValue];
                marketAnnotation.coordinate = location;
                marketAnnotation.title = [objectDictionary objectForKey:@"CompanyName"];
                marketAnnotation.subtitle = [objectDictionary objectForKey:@"MarketAddress"];
                marketAnnotation.phoneNumber = [objectDictionary objectForKey:@"MarketPhone"];
                marketAnnotation.website = [objectDictionary objectForKey:@"Website"];
                [marketLocations addObject:marketAnnotation];
            }

            dispatch_async(dispatch_get_main_queue(), ^ {
                NSLog(@"Annotations Count: %lu", (unsigned long)marketLocations.count);
                [worldView addAnnotations:marketLocations];
            });
        }
        else {
            NSLog(@"Error: %@ %@", error, [error userInfo]);
        }
    }];
}

我发现了问题。对于除了这5个注释之外的所有注释，我的数据库中的经度前面都有一个新的线条字符。
