我缺少什么使我的自定义UITableView单元工作？

Question

我按以下方式创建了一个自定义单元格

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    FacilityResult* currentResult = [_facilityResults objectAtIndex:indexPath.row];
    UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:@"facilityResultDesign" forIndexPath:indexPath];
    }
    return cell;
}

创建FacilityResult对象时，它是自定义单元格的类，我按如下方式更新标签：

@implementation FacilityResult


- (id)initWithModel:(NSString *)name city:(NSString*)city zipcode:(NSString*)zipcode facility_id:(NSString*)facility_id{
    _name = name;
    _zipcode = zipcode;
    _city = city;
    _facility_id = facility_id;
    return self;
}

- (id)initwithModel:(NSMutableDictionary*)propertyDictionary{
    if (![[propertyDictionary allKeys] containsObject:@"name"])
        NSLog(@"Error: Cell Object does not have a name");
    else{
        _name = propertyDictionary[@"name"];
        [propertyDictionary removeObjectForKey:@"name"];
        [_nameField setText:_name];
    }
    if (![[propertyDictionary allKeys] containsObject:@"city"])
        NSLog(@"Error: Cell Object does not have a city");
    else{
        _city= propertyDictionary[@"city"];
        [propertyDictionary removeObjectForKey:@"city"];
        [_cityField setText:_city];
    }
return self;
}


@end

- 更新了ViewDidLoad

- (void)viewDidLoad{
   [super viewDidLoad];
   [[login getSearchFacility] setDelegate:self];
   [_resultTable registerNib:[UINib nibWithNibName:@"FacilityRow" bundle:nil] forCellReuseIdentifier:@"facilityResultDesign"];
   if(_facilityResults==nil)
       _facilityResults = [[NSMutableArray alloc] init];
}

然而，细胞标签不会更新＆＃34;某些公司＆＃34;是我在xcode上为标签输入的默认名称。它应该更新为name1。

当您在xib文件中创建一个单元格时，您应该注册nib，而不是类（如果您完全使用代码，则只注册该类）。您应该在viewDidLoad中进行注册。方法dequeueReusableCellWithIdentifier：forIndexPath：保证返回一个单元格，因此永远不会输入if（cell == nil）子句，这就是为什么在那里注册没有效果。
