I need to display separator line in iOS 7 same like iOS 6 (as my image 2). I am using below code in CellForRowAtIndexPath:
UIView* separatorLineView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 1)];
separatorLineView.backgroundColor = [UIColor colorWithRed:229/255.0 green:229/255.0 blue:229/255.0 alpha:1.0];
[cell.contentView addSubview:separatorLineView];
UIView *customColorView = [[UIView alloc] init];
customColorView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"cell_highlighted.png"]];
cell.selectedBackgroundView = customColorView;
cell.backgroundColor=[UIColor clearColor];
//Separation style for iOS7
if ([tableView respondsToSelector:#selector(setSeparatorInset:)]) {
[tableView setSeparatorInset:UIEdgeInsetsZero];
}
return cell;
I am getting output as below image:
But my output should like below image for both IOS 6 and 7:
Can anyone please help me how to achieve this? Thanks..
contentView doesn't always have the same size as the cell itself, add separator view on top of the cell view above the content view:
separatorLineView.autoresizingMask = UIViewAutoresizingFlexibleWidth;
[cell insertSubview:separatorLineView aboveSubview:cell.contentView];
UITableView has a property separatorInset. Use that to set the insets of the table view separators to zero to let them span the full width of the screen.
[tableView setSeparatorInset:UIEdgeInsetsZero];
OR
You can set separator inset property in xib also. Change it to custom. And make both left and right values to zero.

I am developing an app in which I need " a separator line " after each row of UICollectionViewCell...(like in UITableView after each row).
Anyone having idea how to get this?
Create a UIView with a black background that is 1 pixel high and 320 pixels wide?
For Example
For Horizontal Line
UIView *horizontalLine = [[UIView alloc]initWithFrame:CGRectMake(x cordinate,y cordinate,1,linelenth)];
horizontalLine.backgroundColor = [UIColor blackColor];
[self.view addSubview:horizontalLine];
[horizontalLine release];
For Vertical Line
UIView *verticalLine = [[UIView alloc]initWithFrame:CGRectMake(x cordinate,y cordinate,linelenth,1)];
verticalLine.backgroundColor = [UIColor blackColor];
[self.view addSubview:verticalLine];
[verticalLine release];
I have the following code which draws a separator line and text for a UITableViewCell. It looks fine but when I scroll off screen then back, the separator line is gone but the text is still fine. Any ideas?
static NSString *aProgressIdentifier = #"CustomerCell";
UITableViewCell *aCustomerCell = [iTableView dequeueReusableCellWithIdentifier:aProgressIdentifier];
if (!aCustomerCell) {
aCustomerCell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:aProgressIdentifier] autorelease];
aCustomerCell.contentView.backgroundColor = [UIColor whiteColor];
UIImageView *aLine = [[UIImageView alloc] initWithFrame:CGRectMake(0, 72, 800, 1)];
aLine.backgroundColor = [UIColor colorWithWhite:0.9 alpha:1.0];
[aCustomerCell addSubview:aLine];
[aLine release];
}
CMACustomer *aCustomerObject = aCellObject;
aCustomerCell.textLabel.text = aCustomerObject.customerFullName;
aCustomerCell.detailTextLabel.text = nil;
aCell = aCustomerCell;
Try to add the "aLine" image view as subview of the contentView and not the whole table itself. Probably when the cell is reused and then layoutSubviews is called again, the contentView overlaps (white background) your aLine. Infact consider that iOS default cells have their subviews dynamically redrawn and resized each time they are displayed on screen.
So I would try this:
[aCustomerCell.contentView addSubview:aLine];
If this doesn't work, what can you do is to remove the contentView completely and add your own custom subviews (do this inside the if(!aCustomerCell) and not outside unless you will not get the benefits of the cell re-use):
if (!aCustomerCell) {
aCustomerCell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:aProgressIdentifier] autorelease];
[cell.subviews makeObjectsPerformSelector:#selector(removeFromSuperview)];
UIImageView *aLine = [[UIImageView alloc] initWithFrame:CGRectMake(0, 72, 800, 1)];
aLine.backgroundColor = [UIColor colorWithWhite:0.9 alpha:1.0];
[aCustomerCell.contentView addSubview:aLine];
[aLine release];
}
Finally another check is verify that the cell height is > 72 (it seems a trivial check but its often source of headaches!).
The table view is using a pool of cells, so you can't be sure which one you're getting for any given index path. You can use the cell or the content view, but be sure to add only one of your custom lines per cell.
UIImageView *aLine = (UIImageView *)[cell viewWithTag:64];
if (!aLine) {
// etc.
UIImageView *aLine = [[UIImageView alloc] initWithFrame:CGRectMake(0, 72, 800, 1)];
aLine.tag = 64;
[cell addSubview:aLine];
//
}
// other formatting logic here, you can also hide/show aLine based on biz logic
try adding it to the contentView
[aCustomerCell.contentView addSubview:aLine]
I am using a UITableView with grouping. My first group I have built a custom cell with no background color, and I would also like to remove the border around the cell. How can I do this just for one section?
For my first cell, I would like to set the border/seperator style to [UIColor clearColor].
EDIT: Apple does this in their contacts app, and I wanted to design something similar.
-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
if(indexPath.section == 0){
cell.backgroundView = [[[UIView alloc] initWithFrame:CGRectZero] autorelease];
}
}
I believe what Apple uses for its contact heading is tableView:viewForHeaderInSection: for section 0, instead of a cell in the first section. You can still specify a transparent background and the pinstripe will show behind it. The border will not be there as grouped table view section headers do not have borders.
Whether you built your custom cell in Interface Builder or using code, it should be a fairly trivial task to migrate those views from a UITableViewCell to a UIView for use with tableView:viewForHeaderInSection:.
I don't know if you'll be able to keep the Details title for, say, section 1, unless you make a label containing that word and add it to the section 0 header view manually.
If i understood your question, in the cellForRawIndexPath you should add-
if(indexPath.section==0){
//set the style you wish to add only to the first section
}
good luck
EDIT
I use this function for that -
+(void)setTransparentBgToCell:(UITableViewCell*)cell{
UIView *backgroundView = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 44.0f)];
backgroundView.backgroundColor = [UIColor clearColor];
cell.backgroundView = backgroundView;
[backgroundView release];
cell.selectionStyle=UITableViewCellSelectionStyleNone;
cell.textLabel.backgroundColor = [UIColor clearColor];
cell.detailTextLabel.backgroundColor = [UIColor clearColor];
}

I have a UITableViewController initialized with the grouped style and having multiple sections. For one of these sections, I'd like its constituent cells to be completely transparent and have no border. I plan to assign a custom view for every row in this section, but having that custom view surrounded by the grouped table cell looks bad :(
The following makes the background color of a cell black instead of transparent... And I still don't know how to get rid of the border.
cell.backgroundColor = [UIColor clearColor];
Any pointers? Thanks!
NOTE: This doesn't appear to be working in iOS7 and above. For iOS7 try this answer.
For iOS6 and below, to remove the grouped background from a cell in a grouped table view cell:
This didn't work
cell.backgroundView = nil; // Did Not Work
This did
cell.backgroundView = [[[UIView alloc] initWithFrame:CGRectZero] autorelease];
If you have moved to ARC (I've heard this works, but haven't tested it)
cell.backgroundView = [UIView new];
You have to actually set
tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
to remove the border of cells.
The following hack works in iOS 7 – for now. :)
Subclass UITableViewCell, and use this cell for the section that shouldn't have separators.
Override the addSubview method in your cell subclass:
-(void)addSubview:(UIView *)view
{
// The separator has a height of 0.5pt on a retina display and 1pt on non-retina.
// Prevent subviews with this height from being added.
if (CGRectGetHeight(view.frame)*[UIScreen mainScreen].scale == 1)
{
return;
}
[super addSubview:view];
}
This is what worked for with having a Grouped style table
[tableView setSeparatorColor:[UIColor clearColor]];
This code worked for me :)
[self.tableView setSeparatorColor:[UIColor clearColor]];
[self.tableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];
Set the backgroundView of the cell to nil. For a grouped table, the cell image is part of that view.
cell.backgroundColor = [UIColor clearColor];
cell.backgroundView = [[[UIView alloc] initWithFrame:CGRectZero] autorelease];
Try using tableView.separatorColor = [UIColor clearColor];
And, don't use tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
I tested with both, if style is none, making the section borders invisible is not working, but instead just change its color, and section border will appear to be none.
iOS seems to be differentiating making an object none and making an object transparent
cell.backgroundView = [UIView new];
Works like a charm! Tested! iOS6
As of iOS 8, setting the separator attribute to none works as well.
Setting a content view also gets rid of the border. Set your custom view to cell.contentView.
The easiest way to remove cell borders from a section of grouped-style UITableView:
[tableViewOutlet setBackgroundView:nil];
in the viewDidLoad method.
UIView *backView = [[UIView alloc] initWithFrame:CGRectZero];
backView.backgroundColor = [UIColor clearColor];
cell.backgroundView = backView;
cell.backgroundColor = [UIColor clearColor];
[cell.contentView addSubview:imageView];
If you have a custom UITableCellView then you can add the following method to your view to remove the background view.
- (void)setBackgroundView:(UIView *)backgroundView
{
// We don't want background views for this cell.
[super setBackgroundView:nil];
}
I just thought I would convert my comment to #Intentss into an answer, because it maybe useful for those, using his solution.
Using iOS6.1 with a grouped UITabelView, using ARC:
[tableView setSeparatorColor:[UIColor clearColor]];
Does not work
cell.backgroundView = [[UIView alloc] initWithFrame:CGRectZero];
Does work
I need to set an image to my UITableViewController; if i have just one section on the tableview it works fine with:
self.tableView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"someImage.jpeg"]];
but if there are 2 section the image comes duplicate for each section.
Don't use a pattern image. Use the tableView's backgroundView property:
UIImageView * background = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"someImage.jpeg"]];
[[self tableView] setBackgroundView:background];
[background release];
