我錯過了什麼使我的自定義UITableView單元格工作？

Question

我創建按以下方式定製的細胞

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

當創建FacilityResult對象，它是自定義小區我更新標籤如下類：

@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viewDidLoad中

- (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，標籤不更新「有些公司的」細胞是我對Xcode的標籤輸入的默認名稱。它應該更新爲name1。

當你在一個xib文件中創建一個單元格時，你應該註冊nib而不是類（如果你完全用代碼完成單元的話，只註冊這個類）。你應該在viewDidLoad中註冊。方法dequeueReusableCellWithIdentifier：forIndexPath：保證返回一個單元格，所以你的if（cell == nil）子句永遠不會被輸入，這就是爲什麼註冊沒有效果。
