Can't set custom BackgroundColor on UITableViewCell - iphone

Question

I'm using this code to customize the colour of my cell's background view:
UIColor *cellBackgroundColor = [UIColor colorWithRed:255.0 green:255.0 blue:255.0 alpha:1.0];
cell.contentView.backgroundColor = cellBackgroundColor;
The thing is, it doesn't work. This code though, works perfectly fine:
cell.contentView.backgroundColor = [UIColor redColor];
What's the problem here? Can't I customize the colour of a cell to my liking? Or am I doing something wrong?

Answer 1

you have to set Cell Background with this Delegate:-
- (void)tableView: (UITableView*)tableView
willDisplayCell: (UITableViewCell*)cell
forRowAtIndexPath: (NSIndexPath*)indexPath
{
// UIImage *img = [UIImage imageNamed:#"button.png"]; // get your background image
UIColor *cellBackgroundColor = [UIColor colorWithRed:255/255.0 green:108/255.0 blue:61/255.0 alpha:1.0]; //if you want to set color then use this line
// UIColor *backgroundColor = [[UIColor alloc] initWithPatternImage: img];
cell.backgroundColor = cellBackgroundColor;
cell.textLabel.backgroundColor = [UIColor clearColor];
cell.detailTextLabel.backgroundColor = [UIColor clearColor];
}
Your table look like:-
Taking an RGB color and normalizing it with UIColor on the iPhone
Your values are between 0 and 255. Use them to create a UIColor:
float r; float g; float b; float a;
[UIColor colorWithRed:r/255.f
green:g/255.f
blue:b/255.f
alpha:a/255.f];

Answer 2

Just change :
UIColor *cellBackgroundColor = [UIColor colorWithRed:255.0/255.0 green:255.0/255.0 blue:255.0/255.0 alpha:1.0];
cell.contentView.backgroundColor = cellBackgroundColor;

Answer 3

cell.backgroundView.backgroundColor
you can make a custom view and can change the complete backgroundview
UIView *backgroundViewForCell = [[[UIView alloc] init] autorelease];
backgroundViewForCell.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"row-bg.png"]];
UIView *selectedBackgroundViewForCell = [[[UIView alloc] init] autorelease];
selectedBackgroundViewForCell.backgroundColor = [[UIColor blueColor] colorWithAlphaComponent:.2];
cell.backgroundView = backgroundViewForCell;
cell.selectedBackgroundView = selectedBackgroundViewForCell;

Answer 4

Maybe you can add cell.contentView.backgroundColor = [UIColor clearColor] before you set your color.
The reason is that the backgroundview is at the bottom. The contentview is at the top.
Other LOgic IS
UIView *myBackView = [[UIView alloc] initWithFrame:cell.frame];
myBackView.backgroundColor = [UIColor colorWithRed:1 green:1 blue:0.75 alpha:1];
[cell.contentView addSubview:myBackView];
[myBackView release];

Answer 5

you are on the right track. You just need to replace your color code with this
UIColor *cellBackgroundColor = [UIColor colorWithRed:255.0/255.0 green:255.0/255.0 blue:255.0/255.0 alpha:1.0];
