More UITableViewCell Issues.

[lifeCoder45]

Hey guys. I'm having more issues with my UITableViewCells. First question is, is there a way to hide a subview of a cell while it is about to be deleted? As in when you click on the red circle and the delete button pops up? Can I detect that the delete button is there and hide it when it shows up?

And I have my subview (a label) set to use an autoresizing mask, so when I make the table editable the text slides to the left like it should, but once I delete a row, all of the other row's text just kinda slides to the right a bit, off the screen.

It is very strange.

Please see pics.



This is the table pre edit. Just fine.



This is editable, resizing fine.



This is why I want to just hide the right label.



This happens if I delete a cell, to all of the other ones.

Thanks so much!

Yes, there is a delegate method in the TableView delegate protocol. The one that returns BOOL if you support a particular edit type. Then you check for Delete, make sure you return YES, saying you support DELETE, but also put code in there that can change that view to hidden.

I think that is the approach to use.

Great! I'll look for it! Also I'm thinking that the label text is too far to the right after delete because when I reload the data, the x axis is too far to the right for the new cell, since that delete circle is on the right. Does this sound feasible? And how would I fix that? Would I need a different frame draw for the label?

Thanks!

Can I do something like this?

If self.table == is-editing

x=30

else

x=40

?

Sorry for the formatting, I'm on the iPhone ATM.

Well, if you put all your cell contents into the UITableViewCell's contentView property, it will automatically change the size.

Are you coding this view or using IB?

In IB, you should see the content view being an oval like button with a gray background.

If you are coding then just get add your subviews the cell's contentView property

[cell.contentView addSubView:mySubview];

Here is my whole function for cellAt. I am adding the subview as you suggested, but like I said I think that since I'm calling this method while the table is in delete mode, the x part of the frame is too far to the right.

// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    
	NSUInteger row = [indexPath row];
	
    static NSString *CellIdentifier = @"Cell";
    
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
	}//end if
	
	NSArray *subviews = [[NSArray alloc] initWithArray:cell.contentView.subviews];
	for (UIView *subview in subviews) {
		[subview removeFromSuperview];
	}//end for
	[subviews release];	
	
	CGRect frame = CGRectMake (140, 12, 155, 22);
	
	UILabel *tempLabel = [[UILabel alloc] initWithFrame:frame];
	
	tempLabel.textAlignment = UITextAlignmentRight;
	
	NSString *tempString = [[NSString alloc] initWithFormat:@"%@",[[self.assets objectAtIndex:row] objectForKey:@"value"]];
	
	NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
	[formatter setNumberStyle: NSNumberFormatterCurrencyStyle];
	NSString *numberAsString = [formatter stringFromNumber:[NSNumber numberWithDouble:[tempString doubleValue]]];
	
	tempLabel.text = numberAsString; 
	
	tempLabel.backgroundColor = [UIColor clearColor];
	
	tempLabel.autoresizingMask = UIViewAutoresizingFlexibleWidth;
	
	[cell.contentView addSubview:tempLabel];
	
	[tempLabel release];
	[tempString release];
	[formatter release];
	
	cell.textLabel.text = [[self.assets objectAtIndex:row] objectForKey:@"name"];
	cell.detailTextLabel.text = [[self.assets objectAtIndex:row] objectForKey:@"notes"];
	
    return cell;
	
}

I am not sure the properties, but you have to set a couple more on your UILabel as to if it is bound to the right side of the view, left side etc. Like in Interface Builder how you can go to the ruler tab and they have that box where you click on it and it turns on a line outside the box or inside the box. Not sure what that is called. But in IB when you click on those lines it sets properties as to whether on resize it should stay you x setting from the left etc.

I'd check out the properties for that.
