iphone - 禁用 UITableViewController 的第二行

Question

目前，我有一个UITableView和 2 行。如图所示。它由 中的数组设置ViewDidLoad。

ViewDidLoad

- (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

- (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，当我单击任一行时，它会推送到我只打算用于“统计分析”的同一视图。我想禁用点击图形分析。如何禁用“图形分析”的选择？

谢谢。

Answer 1

nil从您的表视图委托的-tableView:willSelectRowAtIndexPath方法返回。

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

Answer 2

实现 tableView:willSelectRowAtIndexPath: （请参阅文档）并在路径与您想要禁用的路径匹配时返回 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];

- (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;//这样不会调用didSelectrow委托方法。
否则 {
cell.setUserInteractionEnabled = YES;
}
返回单元格；
}
希望它会帮助你。

语用标记 -

杂注标记表视图委托

• (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]; 委托标志 = 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]; 委托标志 = 2;

  }

  if (indexPath.row == 3) { iHadAppDelegate *delegate = [[UIApplication sharedApplication] delegate]; 委托标志 = 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 从我的代码中观察。

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

用于——我想取消选择行的地方[不是每一行——只有我想取消选择的那一行]。
