禁用UITableViewController的第二行

Question

目前，我有一个UITableView并且有两行。如图所示。它由ViewDidLoad中的数组设置。

viewDidLoad中

- (void)viewDidLoad {

 [super viewDidLoad];
self.title = NSLocalizedString(@"Analysis", @"Badminton Analysis Tool");
NSMutableArray *array = [[NSMutableArray alloc] initWithObjects:@"Statistical Analysis", @"Graphical Analysis", nil];
self.booksArray = array;
}

didSelectRowAtIndexPath方法

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {    
NSInteger row = [indexPath row];

if (self.statViewController == nil) {
    StatViewController *statDetail = [[StatViewController alloc] initWithNibName:@"StatViewController" bundle:nil];
    self.statViewController = statDetail;
}
statViewController.title = [NSString stringWithFormat:@"%@", [booksArray objectAtIndex:row]];

[self.navigationController pushViewController:statViewController animated:YES];
}

目前，当我点击任意一行时，它会推送到我打算仅用于“统计分析”的相同视图。我想禁用点击图形分析。如何禁用“图形分析”的选择？

感谢。

Answer 1

从表格视图委托的nil方法返回-tableView:willSelectRowAtIndexPath。

- (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (indexPath.row == 1)
        return nil;
    else
        return indexPath;
}

Answer 2

实现tableView：willSelectRowAtIndexPath :(参见文档），如果路径与您想要禁用的内容相匹配，则返回nil。

Answer 3

您可以使用以下方法取消选择索引处的行： - [self.tableView deselectRowAtIndexPath：indexPath animated：YES];

Answer 4

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {  
      if(indexPath.row == 1) {
         [tableView deselectRowAtIndexPath:indexPath animated:YES];
         return;
       }
}

Answer 5

要禁用蓝色闪光，请执行以下操作：

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

  if (cell == nil)     {
     //usually this is the place where we decide the selection style blue/none  

}
 if（indexPath.row == 1）{
                   cell.setUserInteractionEnabled = NO; //这样就不会调用didSelectrow委托方法。
   否则{
 cell.setUserInteractionEnabled = YES;
}
返回单元;
}
希望它会对你有所帮助。

pragma mark -

pragma mark表视图委托

• （void）tableView：（UITableView *）tableView didSelectRowAtIndexPath：（NSIndexPath *）indexPath {

  if（indexPath.row == 0） {

  iHadAppDelegate *delegate =  [[UIApplication sharedApplication] delegate];
  delegate.flag = 0;
  delegate.mytag = 0;
  
  TableSelectMealViewController *detail = 
  [[TableSelectMealViewController alloc] initWithStyle:UITableViewStyleGrouped];
  detail.rows = 6;   
  [self.navigationController pushViewController:detail animated:YES];
  SelectMealViewController.contentSizeForViewInPopover = CGSizeMake(285, 400);
  
  [detail release];
  [self.tableView deselectRowAtIndexPath:indexPath animated:YES];
  

  }

  if（indexPath.row == 1） {     iHadAppDelegate * delegate = [[UIApplication sharedApplication] delegate];     delegate.flag = 1;

  DatePickerViewController *controller = [[DatePickerViewController alloc]init];
  [self.navigationController pushViewController:controller animated:YES];
  controller.contentSizeForViewInPopover = CGSizeMake(285, 400);
  
  [controller release];
  

  }

  if（indexPath.row == 2） {     iHadAppDelegate * delegate = [[UIApplication sharedApplication] delegate];     delegate.flag = 2;

  }

  if（indexPath.row == 3） {     iHadAppDelegate * delegate = [[UIApplication sharedApplication] delegate];     delegate.flag = 3;

  TableSelectMealViewController *detail = 
  [[TableSelectMealViewController alloc] initWithStyle:UITableViewStyleGrouped];
  //detail.rows = 10;
  [self.navigationController pushViewController:detail animated:YES];
  
  SelectMealViewController.contentSizeForViewInPopover = CGSizeMake(285, 400);
  
  [detail release];
  [self.tableView deselectRowAtIndexPath:indexPath animated:YES];
  

  }

}

@ k.Honda从我的代码中获取观察结果。

    [self.tableView deselectRowAtIndexPath:indexPath animated:YES];

用于 - 我想取消选择行[不是每一行 - 只有我要取消选择的行]。
