Question

我的表格认为,牢房很多。每个牢房都有自己的UIText油田。我在方案上增加了案文领域。我想每个案文。 ed子被击中时,现场出现。 (现在的表格采用编辑方式),当再次施加压力时,我想所有文本领域都会消失(打破编辑模式)。我知道,我可以使用<条码>隐藏的财产实现这一点,但我尝试采用这种方法:

    - (IBAction)editButton:(id)sender 
{
    if (self.editing) 
    {
        [self setEditing:NO animated:YES];
        [self.myTableView setEditing:NO animated:YES];
        EditButton.title = @"Edit";
        cellText.hidden = YES;  //<-- THIS IS THE CODE
    } 
    else 
    {
        [self setEditing:YES animated:YES];
        [self.myTableView setEditing:YES animated:YES];
        EditButton.title = @"Done";
        cellText.hidden = NO;  //<-- THIS IS THE CODE
    }
}

但它只显示并隐藏了VERY LAST小组的文字。怎样才能将其带到哪里,然后又会展示EVERY手机的正文。 thanks!

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

    cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil)
     {
         cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];


         cellText = [[UITextField alloc]init];
         [cellText setFrame:CGRectMake(190, 15, 55, 30)];
         cellText.text = @"1";
         cellText.borderStyle = UITextBorderStyleRoundedRect;
         cellText.hidden = YES;
         cellText.userInteractionEnabled = NO;
         [cell addSubview:cellText];
    }    

return cell;
}

提前感谢!

You can get rid of this issue, using this trick, I am not sure as if it would create the memory leak within your code.Since, it create new cell each time.But surely you can use it,if you don t get some proper way of doing it. ;)

- (IBAction)editButton:(id)sender 
{
 if (self.editing) 
        {
            [self setEditing:NO animated:YES];
            [self.myTableView setEditing:NO animated:YES];
            EditButton.title = @"Edit";

        } 
        else 
        {
            [self setEditing:YES animated:YES];
            [self.myTableView setEditing:YES animated:YES];
            EditButton.title = @"Done";

        }
        [self.myTableView reloadData];
}

在重载了表格后,检查了ForRowAtIndexPath的病情,或者将自我编辑的价值传递给文本现场,使之隐藏/how。

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

    UITableViewCell *cell  = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];


    cellText = [[UITextField alloc]init];
    [cellText setFrame:CGRectMake(190, 15, 55, 30)];
    cellText.text = @"1";
    cellText.borderStyle = UITextBorderStyleRoundedRect;
    cellText.hidden = YES;
    cellText.backgroundColor = [UIColor redColor];
    cellText.userInteractionEnabled = NO;
    [cell addSubview:cellText];

    cellText.hidden=!self.editing;

    return cell;
}

虽然你为每个牢房设立了一个文本领域,但仅提及点名的Ivar编码cellText。因此,你只展示/宣传文本。

I suggest you reload the table when toggling the editing mode, and set the text fields visibility in tableView:cellForRowAtIndexPath:.

Oh, and you should release cellText after adding it as a subview. Otherwise you are leaking memory. And it is highly recommended that you add subviews to UITableViewCell content view, rather than directly to the cell.

D. 守则

- (void)viewDidLoad {
    [super viewDidLoad];
    self.navigationItem.rightBarButtonItem = self.editButtonItem;
}



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

static NSString *CellIdentifier = @"Cell";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
UITextField * cellText = [[UITextField alloc] initWithFrame:CGRectMake(1, 1, 100, 30)];
cellText.tag = 1;
cellText.textColor = [UIColor darkTextColor];
//cellText.numberOfLines = 0;
cellText.font = [ UIFont fontWithName: @"Helvetica-Bold" size: 12.0 ] ; 
cellText.backgroundColor = [ UIColor clearColor ] ;
cellText.text = @"123";
    cellText.hidden = YES;
[cell.contentView addSubview:cellText];
[cellText release];
cellText =nil;

// Set up the cell...


return cell;
}
- (UITableViewCellEditingStyle)tableView:(UITableView *)aTableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath {
// Detemine if it s in editing mode
  UITextField *cellText = (UITextField *)[[aTableView cellForRowAtIndexPath:indexPath] viewWithTag:1];
if (!self.editing) 
{
    [self setEditing:NO animated:YES];
    [self.tableView setEditing:NO animated:YES];
   // EditButton.title = @"Edit";

    cellText.hidden = YES;  //<-- THIS IS THE CODE
} 
else 
{
    [self setEditing:YES animated:YES];
    [self.tableView setEditing:YES animated:YES];
  //  EditButton.title = @"Done";
    cellText.hidden = NO;  //<-- THIS IS THE CODE
}

return UITableViewCellEditingStyleNone;
}

朋友们,这一法典正在对我进行罚款,相信你也有一天的 gr。

这实际上是正常的。补充材料下的 Apple果文件:

Views can have only one superview. If view already has a superview and that view is not the receiver, this method removes the previous superview before making the receiver its new superview.

因此,它将在囚室到达最后牢房之前,继续拆除牢房。
