我怎麼能刪除我的表的單元格陣列

Question

我有從表中刪除行的問題。我有一個單元格的表和sql數據庫的類。然後我從數據庫中加載表格，並做到與它無關。現在，當我嘗試通過索引路徑刪除行時，我有一個異常。

- (void)viewDidLoad 
    { 
     [super viewDidLoad]; 

     databasecontroller=((SexyGirlsWeatherAppDelegate *)[[UIApplication sharedApplication] delegate]).databasecontroller; 
     self.favorites=[databasecontroller select:@"SELECT Name, id FROM Favorites"]; 
    } 

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
    { 
     static NSString *CellIdentifier = @"Cell"; 
     cell = (CustomCell *)[favoritesTableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
     if (cell == nil) { 
      NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil]; 
      cell = [nib objectAtIndex:0]; 
     } 
     [favoritesTableView setBackgroundColor:[UIColor clearColor]]; 
     cell.name.text = [[favorites objectAtIndex:indexPath.row] objectForKey:@"Name"]; 
     cell.currenttemp.text=@"+45 C"; 
     cell.currentweather.image=[UIImage imageNamed:@"sunny"]; 
     //[cell.selectcell setBackgroundImage:[UIImage imageNamed:@"selectfalse"] forState:UIControlStateNormal]; 
     cell.razdelitel.image=[UIImage imageNamed:@"delenie"]; 
     if(editModeOn==YES) [cell EditModeON]; 
     return cell; 
    } 


- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
if(editModeOn==YES) 
{ 
    int existcount=0; 
    for(int z=0; z<[selectrowsarray count];z++) 
    { 
     if([selectrowsarray objectAtIndex:z]==indexPath) // check for exist of item 
     { 
      [selectrowsarray removeObjectAtIndex:z]; 
      existcount++; 
     } 

    } 
    if(existcount==0) 
    { 
     [selectrowsarray addObject:indexPath]; 
    } 
} 
} 
-(IBAction) deleteSelectedTownsFromFavorites:(id)sender // here i try to delete cells 
{ 
    // [favoritesTableView beginUpdates]; 
    // [databasecontroller exec:[NSString stringWithFormat:@" DELETE FROM Favorites WHERE Id=%d", 3]]; 
// [favoritesTableView reloadData]; 
    // [databasecontroller exec:@"UPDATE Favorites"]; 
// for(int t=0; t<[selectrowsarray count];t++) 
// { 
// 
    [favorites removeLastObject]; 
     [favoritesTableView deleteRowsAtIndexPaths:selectrowsarray withRowAnimation:UITableViewRowAnimationMiddle]; 
// } 
    optionsview.hidden=true; 
    // [favoritesTableView endUpdates]; 

} 


- (NSInteger)tableView:(UITableView *)favoritesTableView numberOfRowsInSection:(NSInteger)section 
{ 
    //return [favorites count]; 
    return [favorites count]; 
} 

我怎樣才能合併2個數組（從數據庫和selectcelladdresses）糾正刪除行？

您還必須從數據源中刪除單元格。
