Kal datasource代表

Question

我使用Kal https://github.com/klazuka/Kal來實現日曆。我使用的是故事板，所以我將KalViewController作爲子視圖添加到容器視圖控制器。

kal.delegate = self; 

kal.dataSource = dataSource; 

dataSource = [[CalendarDataSourceDelegate alloc] init]; 

kal = [[KalViewController alloc] init]; 

[self addChildViewController:kal]; 
[kal didMoveToParentViewController:self]; 
[self.calendarioView addSubview:kal.view]; 



[clickEvent insertPrintAdd:zona_competicion]; 

我使用一個外部對象作爲數據源的代表，而是由Web服務從我的後端讀取數據後，我不知道該怎麼稱呼代表們獲取的數據加載日曆：

@implementation CalendarDataSourceDelegate 


    - (id)init 
    { 
     if ((self = [super init])) { 
      items = [[NSMutableArray alloc] init]; 
      matches = [[NSMutableArray alloc] init]; 
      buffer = [[NSMutableData alloc] init]; 

     } 
     [self fetchHolidays]; 

     return self; 
    } 

    - (eventMatch *)eventAtIndexPath:(NSIndexPath *)indexPath 
    { 
     return [items objectAtIndex:indexPath.row]; 
    } 

    #pragma mark UITableViewDataSource protocol conformance 

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
    { 
     static NSString *identifier = @"MyCell"; 
     eventNoAddedCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier]; 
     if (!cell) { 
      cell = [[eventNoAddedCell alloc] initWithStyle:UITableViewCellSelectionStyleNone reuseIdentifier:identifier]; 
      cell.selectionStyle = UITableViewCellSelectionStyleNone; 
      cell.imageView.contentMode = UIViewContentModeScaleAspectFill; 
     } 

     eventMatch *event = [self eventAtIndexPath:indexPath]; 

     cell.escudoLocal.image = [UIImage imageNamed:[NSString stringWithFormat:@"%@.png",event.equipoLocal ]]; 
     cell.escudoVis.image = [UIImage imageNamed:[NSString stringWithFormat:@"%@.png",event.equipoVisitante ]]; 
     cell.equipoLocal.text = event.equipoLocal; 
     cell.equipoVisitante.text = event.equipoVisitante; 
     cell.competicion.text = event.competicion; 
     cell.jornada.text = event.jornada; 
     cell.hora.text = event.hora; 
     cell.canalesTV.text = event.canalesTV; 

     [self fetchHolidays]; 

     return cell; 
    }

     NSArray *array = [tempDic valueForKey:@"nodes"]; 

     NSDateFormatter *fmt = [[NSDateFormatter alloc] init] ;

第一，我覺得奇怪的是，你使用它後你的頁頭KalViewController，我這樣做只是以相反的順序：

kal = [[KalViewController alloc] init]; 
kal.delegate = self; 
kal.dataSource = dataSource; 

然後你爲什麼不只是調用？：

[kal reloadData];
