Hide UIButton of UITableviewcell - iphone

Question

I have one Simple critical Problem in my code .
On my Tableview when I pressed on my Edit button (which is on navigationbar) It takes me to edit method of UITableview . I want to hide button and label which is on My Cell .
Code :
I am adding my Button like this ..
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *currentCell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
currentCell = nil;
if (currentCell==nil)
{
currentCell=[[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
BtnEmail=[UIButton buttonWithType:UIButtonTypeCustom];
//BtnEmail = (UIButton *)[currentCell viewWithTag: 3];
BtnEmail.frame=CGRectMake(265, 17, 25, 25);
BtnEmail.tag=indexPath.row;
//[BtnEmail setTitle:#"E-mail" forState:UIControlStateNormal];
[BtnEmail setBackgroundImage:[UIImage imageNamed:#"email.png"] forState:UIControlStateNormal];
[BtnEmail addTarget:self action:#selector(BtnEmail:) forControlEvents:UIControlEventTouchUpInside];
[currentCell.contentView addSubview:BtnEmail];
[currentCell.contentView bringSubviewToFront:BtnEmail];
return currentCell;
}
My Edit button is Declare like this
Edit Button :
self.navigationItem.rightBarButtonItem = self.editButtonItem;
And On edit click My this method will call .
- (void)setEditing:(BOOL)editing animated:(BOOL)animated
{
[super setEditing:editing animated:animated];
[listTableView setEditing:editing animated:animated];
if(editing)
{
self.navigationItem.leftBarButtonItem.enabled = NO;
//BtnEmail.frame=CGRectMake(355, 17, 25, 25);
BtnEmail.hidden = TRUE;
}
else
{
self.navigationItem.leftBarButtonItem.enabled = YES;
//BtnEmail.frame=CGRectMake(265, 17, 25, 25);
BtnEmail.hidden = FALSE;
}
[super setEditing:editing animated:animated];
}
In this case my Last cell Button and Lable gonna hide not all . I need to hide all the UIButton of my Cell .
Like if I have 3 cell on table then it will hide only last button only ..
Thanks .

You can do it simply making a conditional check in cellForRow and reload the table view when the editing changed.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
// Do your other stuff
// Add this conditional check
if (tableView.editing)
{
BtnEmail.hidden = YES;
}
else
{
BtnEmail.hidden = NO;
}
[currentCell.contentView addSubview:BtnEmail];
[currentCell.contentView bringSubviewToFront:BtnEmail];
return currentCell;
}
- (void)setEditing:(BOOL)editing animated:(BOOL)animated
{
[super setEditing:editing animated:animated];
[listTableView setEditing:editing animated:animated];
// Reload the table view
[listTableView reloadData];
// Do your other stuff
}
But it easy to create that button by using a custom cell. Here you are adding the button again and again. Otherwise move the button creating code to the if(cell == nil) block

That is because you are declaring
BtnEmail.hidden = FALSE;
which in this case is your last allocated button in cellForRowAtIndexPath method. Try something like this:
if(editing)
{
self.navigationItem.leftBarButtonItem.enabled = NO;
//BtnEmail.frame=CGRectMake(355, 17, 25, 25);
For(int i=0; i< [tableArray count]; i++)
{
UITableViewCell *cell = (UITableViewCell *)[tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:i inSection:0]] ;
UIButton *btn=(UIButton *)[cell viewWithTag:i];
btn.hidden = TRUE;
}
}
else
{
self.navigationItem.leftBarButtonItem.enabled = YES;
//BtnEmail.frame=CGRectMake(265, 17, 25, 25);
For(int i=0; i< [tableArray count]; i++)
{
UITableViewCell *cell = (UITableViewCell *)[tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:i inSection:0]] ;
UIButton *btn=(UIButton *)[cell viewWithTag:i];
btn.hidden = FALSE;
}
}
