iphone - 如何在 ios uitableview(组表)中执行验证？

Question

在我的应用程序中，我使用了 UItableview 组表。其中有两个部分，我想对其进行验证。

例如:在第 1 部分中有两行，如果用户选择第 1 行，则用户必须从第 2 部分中选择一些值，如果用户在第 1 部分中选择了第二行，则无需在第 2 部分中选择。

以下是我的代码:

- (void)viewDidLoad
{
    NSArray *arr_data1 =[[NSArray alloc]initWithObjects:@"Yes",@"No",nil];
    NSArray *arr_data2 =[[NSArray alloc] initWithObjects:@"Monotherapy",@"Adjunctive",nil];

    NSDictionary *temp =[[NSDictionary alloc]
                         initWithObjectsAndKeys:arr_data1,@"",arr_data2,
                         @"Was it monotherapy or adjunctive",nil];
    self.tableContents =temp;
    self.arr_data =[[self.tableContents allKeys]
                      sortedArrayUsingSelector:@selector(compare:)];

    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return [self.arr_data count];
}

-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
    return [self.arr_data objectAtIndex:section];
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    NSArray *listData =[self.tableContents objectForKey:
                        [self.arr_data objectAtIndex:section]];
    return [listData count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView
         cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier";

    NSArray *listData =[self.tableContents objectForKey:
                        [self.arr_data objectAtIndex:[indexPath section]]];

    UITableViewCell * cell = [tableView
                              dequeueReusableCellWithIdentifier: SimpleTableIdentifier];

    if(cell == nil) {



cell = [[UITableViewCell alloc]
             initWithStyle:UITableViewCellStyleDefault
             reuseIdentifier:SimpleTableIdentifier];


    }

NSUInteger row = [indexPath row];

cell.textLabel.text = [listData objectAtIndex:row];

return cell;

}



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

    NSArray *listData =[self.tableContents objectForKey:
                        [self.arr_data objectAtIndex:[indexPath section]]];
    NSUInteger row = [indexPath row];
    NSLog(@"fdfdfdf=%d",[indexPath row]);
    NSString *rowValue = [listData objectAtIndex:row];

    if ([rowValue isEqualToString:@"Yes"])
    {
        NSString *message = [[NSString alloc] initWithFormat:@"%@",rowValue];
        UIAlertView *alert = [[UIAlertView alloc]
                              initWithTitle:@"You selected"
                              message:message delegate:nil
                              cancelButtonTitle:@"OK"
                              otherButtonTitles:nil];
        [alert show];
    }



    [tableView deselectRowAtIndexPath:indexPath animated:YES];
}

In - (void)tableView:(UITableView *)tableView 
didSelectRowAtIndexPath:(NSIndexPath *)indexPath ,
you can check the section you need by using the following code:

- (void)tableView:(UITableView *)tableView 
  didSelectRowAtIndexPath:(NSIndexPath *)indexPath
 {
  if(indexPath.section == 0)
  {
   //do as per you requirement

  }
  else if(indexPath.section == 1)
  {
   //do as per you requirement

  }

}
