I am using a image view as tableview cell background view. When I am compiling my source in xcode 4.x, it works fine i.e, In both iOS 6.x and 7.0 it is working fine. But when I compile my source in xcode 5.0, the background image view is not appearing iOS 7.
Any idea, why it is not working? is there any restrictions on uitableview cell background view in iOS 7?
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:accountProfileTypeCell];
UIImageView *cellBgView =[[UIImageView alloc]init];
[cellBgView setImage:[UIImage imageNamed:#"cellBgView.png"]];
[cell setBackgroundView:cellBgView];
}
try adding : cell.backgroundColor = [UIColor clearColor];
You must set the background in willDisplayCell. The below code is same as yours only thing is that move it in willDisplay method
-(void) tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{
if(cell.backgroundView==nil){
UIImageView *cellBgView =[[UIImageView alloc]init];
[cellBgView setImage:[UIImage imageNamed:#"cellBgView.png"]];
[cell setBackgroundView:cellBgView];
}
}
Try this. It's work for me
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:accountProfileTypeCell];
UIView *cellBgView =[[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, [cell frame].size.width, [cell frame].size.height)];
[cellBgView setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:#"cellBgView.png"]]];
[cell setBackgroundView:cellBgView];
The only thing missing is setting frame to cellBgView. Setting image to it will not resize imageView. However if you initialize imageView with initWithImage: , it will resize imageView to fit the image.
You just need to apply autosizing in your imageview.
If your imageview is applied to an entire screen. Assign all margins to it.
Checkout the image

I am loading custom separator image in uitableview cell.
Here is my code :
- (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath: (NSIndexPath *)indexPath
{
static NSString *CellID=#"Cell"
MyTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellID];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:SwitchCellIdentifier];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
UIImageview *aSwitch = [[UIImageview alloc] initWithImage:[UIImage imageNamed:#"divider.png"]];
separator.frame = CGRectMake(0,50,320,1);
[cell.contentView addSubview:seperator];
}
if(cell.height == 22)
{
/// here i am setting frame for uiimageview
}
but i am getting seperator image disappears for only one row out of 20 while scrolling.
Can you please help why it is loading like this.
If you've put your separator UIImage out of the bounds of the cell, and set cell.clipsToBounds = NO; to have the separator image displayed, the separator image might get hidden by drawing the next cell.
You can't control the z-index of the cells as they're being drawn on screen, it depends from where you're scrolling (bottom to top, or top to bottom).
If that's indeed you're issue, you can either put the divider inside the cell's frame, or if your separator is thin enough use:
[TableView setSeparatorColor:[UIColor colorWithPatternImage:[UIImage imageNamed:...]]];
self.tblView=[[UITableView alloc] initWithFrame:CGRectMake(0,0,320,370) //set as u need
style:UITableViewStylePlain];
self.tblView.delegate=self;
self.tblView.dataSource=self;
[self.view addSubview:self.tblView];
UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 10)];//set as u ne
v.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"divider.png"]];
[self.tblView setTableHeaderView:v];
[self.tblView setTableFooterView:v];
[v release];
I've got a table view, how can I select a cell with different colour? Or how can I set the image of selection? thanks
You can easily change the cells selection style to gray:
[myTableView setSelectionStyle: UITableViewCellSelectionStyleGray];
Or you can change the contentView's backgroundColor in the willDisplayCell delegate:
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
cell.backgroundColor = [UIColor redColor];
}
Another way would be to create a custom cell and change the color of the Background.
UIView *bgColorView = [[UIView alloc] init];
[bgColorView setBackgroundColor:[UIColor redColor]];
[cell setSelectedBackgroundView:bgColorView];
[bgColorView release];
Presumably you could do the same with a UIImageView as well
UIImageView *bgImageView = [[UIImageView imageNamed:#"Your Image"];
[cell setSelectedBackgroundView:bgImageView];
[bgImageView release];
In my application ,I am using Grouped style for TableView. In that I want to customize the cell selection Style.I want that selection Style to be red.
I am using the below code for that:
UIView *bgColorView = [[UIView alloc] init];
[bgColorView setBackgroundColor:[UIColor redColor];
[cell setSelectedBackgroundView:bgColorView];
[bgColorView release];
By using the above code. I have a problem.Since I have taken grouped Style table , in the
selection of first and last rows, the selection is appear with sharp edged rectangle instead of
appeaing round Corners.
Can Anyone Help me in this.
Thanks in Advance.
Try this ,
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"CellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
cell.selectedBackgroundView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"SelectedCellBackground.png"]] autorelease];
}
// Cell configuration takes place here
}
add QuartzCore framework. and import QuartzCore/QuartzCore.h framework in .m file. and after that add following code in cellForRowAtIndexPath Method.
UIImageView *imv = [[UIImageView alloc]init];
imv.backgroundColor=[UIColor redColor];
[cell setSelectedBackgroundView:imv];
CALayer *layer = imv.layer;
[layer setMasksToBounds:YES];
[layer setCornerRadius:10.0];
[imv release];
Override -(void)setSelected:animated: in your subclass.
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
if (selected)
[self setBackgroundColor:[UIColor redColor]];
else
[self setBackgroundColor:[UIColor whiteColor]];
}
You can add fancy animation here to blend in and fade out the background upon selection and deselection if animated is YES.
In general UITableViewCell can be a bit awkward to subclass, be patient here.
UIImageView *imageVieww=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, cell2.bounds.size.width, cell2.bounds.size.height)];
imageVieww.image=[UIImage imageNamed:#"mavilik.png"];
[cell2 setSelectedBackgroundView:imageVieww];
[imageVieww release];
i have a UItableview and i want to change the cell background when it is seleceted and keep it like that so i tried to use
[cell setBackgroundColor:[UIColor purpleColor]];
but that made other cells get colored at same time and i dont know why
i also tried to use
[cell.textLabel setBackgroundColor:[UIColor purpleColor]];
but when i select another cell the background go back to white color
so any ideas for solving that problem??
UIView *backgroundView = [[UIView alloc] initWithFrame:cell.selectedBackgroundView.frame];
[backgroundView setBackgroundColor:[UIColor purpleColor]];
[cell setSelectedBackgroundView:backgroundView];
[backgroundView release];
since 3.0, set it in the willDisplayCell method:
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
cell.backgroundColor = [UIColor redColor];
}
Subclass UITableViewCell by yourself class, i.e. MyTableViewCell and reimplement the selected function.
-(void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
UIView *backgroundView = [[UIView alloc] initWithFrame:self.selectedBackgroundView.frame];
[backgroundView setBackgroundColor:[UIColor purpleColor]];
[self setSelectedBackgroundView:backgroundView];
}
I've tried numerous ways of setting the background image of an unselected table cell, but without success:
1- In IB setting the image field
2- cell.contentView.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:#"list.png"]];
3- cell.imageView.image = [UIImage imageNamed:#"list_selected.png"];
All seem to fail. The image setting for selected cell works, but not for an unselected cell. Anyone having any idea what might be wrong here?
Thanks
Try setting the backgroundView to an imageView of the image.
Code example from Jason Moore (with TomH's correction):
cell.backgroundView = [[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"foo.png"]] autorelease];
cell.backgroundImage no longer exists. Instead use:
cell.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"foo.png"]];

I've been doing this using the following UITableViewDelegate method, and setting the cell.backgroundColor property. It gets called last, right before the cell is actually drawn on the screen:
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.row%2)
cell.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"TableCell-BG-Dark.png"]];
else
cell.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"TableCell-BG-Light.png"]];
}
And yes, I'm using a custom subclass of UITableViewCell.
try doing this :
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:DateCellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:DateCellIdentifier] autorelease]
UIImageView* img = [[UIImageView alloc]initWithImage:[UIImage imageNamed:#"gradient.png"]];
[cell setBackgroundView:img];
[img release];
}
cell.textLabel.text = #"Text";
}
I've also had problems with trying to change the background colour of cells, i ended up subclassing the cell for different reasons, this is my cell background alternation code:
if (indexPath.row % 2 == 0) {
cell.contentView.backgroundColor = [UIColor colorWithWhite:230.0/255 alpha:1];
} else {
cell.contentView.backgroundColor = [UIColor colorWithWhite:242.0/255 alpha:1];
}
