在uitableview單元格中的自定義複選框出錯

即時獲取錯誤：*終止應用程序，由於未捕獲的異常'NSInternalInconsistencyException'，原因：'嘗試將0行插入0節，但0節後只有0行更新'*在uitableview單元格中的自定義複選框出錯

我有2個部分，我試圖做到這一點，當你點擊其中一個部分的單元格的複選框時，它會轉到另一部分（例如：第1部分 - >第2部分）

這裏是我的一些相關的代碼：

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ 
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"UITableViewCell"]; 
    if (!cell) 
     cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"UITableViewCell"]; 
    if([indexPath section] == 0){ 
    cell.textLabel.text = [[[taskArray objectAtIndex:[indexPath row]] taskName] uppercaseString]; 
    cell.imageView.image = [UIImage imageNamed:@"checkboxtry2.png"]; 
    } else if ([indexPath section] == 1) { 
    cell.textLabel.text = [[[completedArray objectAtIndex:[indexPath row]] taskName] uppercaseString]; 
    cell.imageView.image = [UIImage imageNamed:@"checkboxtry2selected.png"]; 
    } 

    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(handlechecking:)]; 
    [cell.imageView addGestureRecognizer:tap]; 
    cell.imageView.userInteractionEnabled = YES; 
    return cell; 
} 
-(void)handlechecking:(UITapGestureRecognizer *)t{ 
     CGPoint tapLocation = [t locationInView:self.tableView]; 
     NSIndexPath *tappedIndexPath = [self.tableView indexPathForRowAtPoint:tapLocation]; 

     if (tappedIndexPath.section == 0) { 
      [completedArray addObject:[taskArray objectAtIndex:tappedIndexPath.row]]; 
      [taskArray removeObject:[taskArray objectAtIndex:tappedIndexPath.row]]; 
     } 
     else { 
      [taskArray addObject:[completedArray objectAtIndex:tappedIndexPath.row]]; 
      [completedArray removeObject:[completedArray objectAtIndex:tappedIndexPath.row]]; 
     } 
     [self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:tappedIndexPath] withRowAnimation: UITableViewRowAnimationFade]; 
}

我有兩個數組：taskArray它處理在第0對象和completedArray負責處理在部分對象1.

---編輯--- 這是我現在有： TableViewController.h

@interface ToDoTableViewController : UITableViewController <Properties2ViewControllerDelegate, UITableViewDelegate, SettingsViewControllerDelegate>

    [cell setBackgroundColor:[UIColor colorWithRed:236.0/255 green:240.0/255 blue:241.0/255 alpha:1.0f]];

} 
-(void)properties2ViewControllerDidEnterPropertiesSuccesfully:(Tasks *)t{ 
    if (![[t taskName] isEqual: @""]) { 
    [taskArray addObject:t]; 
    } 
    [self.tableView reloadData]; 
}

Properties2ViewController.m

-(IBAction)dismiss:(id)sender{ 
    testTask = [[Tasks alloc]init]; 
    testTask.taskName = taskName.text; 
    testTask.timeInterval = datePicker.countDownDuration; 
    testTask.dateCreated = [NSDate date]; 
    if ([self.delegate respondsToSelector:@selector (properties2ViewControllerDidEnterPropertiesSuccesfully:)]){ 
     [self.delegate properties2ViewControllerDidEnterPropertiesSuccesfully:testTask]; 
    } 
    [self dismissViewControllerAnimated:YES completion:NULL]; 
}

Properties2viewcontroller是一個模式控制器，它將Task對象添加到taskArray。

嘗試重新加載整個表視圖，你改變一排以上時你將它從一個部分移動到另一個部分。 – Wain

您可以爲此場景提供屏幕截圖。所以我可以幫你以你想要的方式 - –

首先使用你的數組的屬性（例如self.taskArray，而不是taskArray）。通過這種方式，你的屬性的setter和getters將被自動調用，你可以避免一些可能的內存錯誤。爲數組添加惰性實例（例如 - （NSMutableArray *）taskArray {if（！_taskArray）{_taskArray = [NSMutableArray array];} return _taskArray;}）並將其從viewDidLoad中移除。設置特殊的斷點來查看應用程序崩潰的方法。 Post方法將數據添加到所有空陣列。 – Numeral

您正在嘗試重新加載行，但你真正想要做的是從0段刪除的行並將其添加到第1節或反之亦然。因此，在handlechecking方法，你必須寫這樣的事：

-(void)handlechecking:(UITapGestureRecognizer *)t{ 

CGPoint tapLocation = [t locationInView:self.tableView]; 
NSIndexPath *tappedIndexPath = [self.tableView indexPathForRowAtPoint:tapLocation]; 
NSIndexPath *newIndexPath = nil; 

if (tappedIndexPath.section == 0) { 

    NSUInteger newRowIndex = self.sectionTwoArr.count; 
    [self.sectionTwoArr addObject:[self.sectionOneArr objectAtIndex:tappedIndexPath.row]]; 
    [self.sectionOneArr removeObject:[self.sectionOneArr objectAtIndex:tappedIndexPath.row]]; 
    newIndexPath = [NSIndexPath indexPathForRow:newRowindex inSection:1]; 
} else { 

    NSUInteger newRowIndex = self.sectionOneArr.count; 
    [self.sectionOneArr addObject:[self.sectionTwoArr objectAtIndex:tappedIndexPath.row]]; 
    [self.sectionTwoArr removeObject:[self.sectionTwoArr objectAtIndex:tappedIndexPath.row]]; 
    newIndexPath = [NSIndexPath indexPathForRow:newRowindex inSection:0]; 
} 
[self.tableView beginUpdates]; 
[self.tableView insertRowsAtIndexPaths:@[newIndexPath] withRowAnimation:UITableViewRowAnimationNone]; 
[self.tableView deleteRowsAtIndexPaths:@[tappedIndexPath] withRowAnimation:UITableViewRowAnimationNone]; 
[self.tableView endUpdates]; 
}

，不幸的是沒有工作。我得到一個錯誤：我收到終止應用程序錯誤*由於未捕獲的異常「NSRangeException」，原因是：「* - [__ NSArrayM objectAtIndex：]：索引0超越界限空陣」 – EvilAegis

user2533646，我編輯我的答案，並測試它在測試項目上。它應該工作 – Numeral

嗯它半工作。有時它的工作，但是當我邀請了幾位行我得到：終止應用程序由於未捕獲的異常「NSInternalInconsistencyException」，理由是：「無效的更新：在第0包含在後的現有部分的行數行數無效更新（0）必須更新（2）之前等於包含在該部分中的行的數目，加上或減去插入或從該部分（0插入時，1刪除）和加上或刪除的行的數量減去的數行移入或移出該部分（0移入，0移出）。' – EvilAegis

你的代碼看起來正確，但我會冒險猜測問題出在你的tableView：numberOfRowsInSection：方法中。你是否爲每個部分返回適當的行數？應該是這樣的：

if([indexPath section] == 0){ 
    return [taskArray count]; 
} else { 
    return [completeArray count]; 
}
