Change UITable section backgroundColor without loo

问题:

i have changed the backgroundColor/backgroundImage of my tableviews sections.
I am using plain tableView. No worries, get worked without problems with this code:

-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
UIView *sectionView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 728, 40)] autorelease];
sectionView.backgroundColor = [UIColor greenColor];

//For using an image use this:
//sectionView.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"whiteBackground.png"]];

return sectionView;
}  

Problem now is, the section title is gone.

I am setting the title of the section with this code:

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {

if ([tableView isEqual:self.searchDisplayController.searchResultsTableView]){
    return @"";
} else {    
    id <NSFetchedResultsSectionInfo> sectionInfo = [[self.fetchedResultsController sections] objectAtIndex:section];
    return [sectionInfo name];
}


}

i am getting the section titles if i do not use

-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section  

Need your help.
Thanks a lot.

EDIT 1:

Thanks to Mutix:

in my case, the answer would be:

-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {




UIView *sectionView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 728, 20)] autorelease];
sectionView.backgroundColor = [UIColor greenColor];

//sectionView.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"whiteBackground.png"]];

//Add label to view
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 728, 20)];
titleLabel.backgroundColor = [UIColor clearColor];

//section Title
if ([tableView isEqual:self.searchDisplayController.searchResultsTableView]){
    titleLabel.text = @"";
} else {    
    id <NSFetchedResultsSectionInfo> sectionInfo = [[self.fetchedResultsController sections] objectAtIndex:section];
    titleLabel.text = [sectionInfo name];
}



[sectionView addSubview:titleLabel];
[titleLabel release];

return sectionView;

}

回答1:

The viewForHeaderInSection overrides the titleForHeaderInSection method.

To add a title to your header when using viewForHeaderInSection you will need to add a label to the section header view like so:

-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {

    UIView *sectionView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 728, 40)] autorelease];

    sectionView.backgroundColor = [UIColor greenColor];

    //Add label to view
    UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 728, 40)];
    titleLabel.text = @"title";
    [sectionView addSubview:titleLabel];
    [titleLabel release];

    return sectionView;
}

We have a better solution for this from iOS6 onwards:

There is a delegate method

- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section

You can use this method like this

-(void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section {

     //Set the background color of the View
     view.tintColor = [UIColor blueColor];

     // Text Color
     UITableViewHeaderFooterView *header = (UITableViewHeaderFooterView *)view;
     [header.textLabel setTextColor:[UIColor whiteColor]];

}

Implement method below from UITableViewDelegate, and needed ui view.

func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    let view = UITableViewHeaderFooterView()
    view.contentView.backgroundColor = UIColor(white: 0.97, alpha: 1)
    return view
}

If you need change footer use similar code in ...viewForFooterInSection.. method

Want to draw you own font, use similar customization:

...    
let label = UILabel(frame: CGRectMake(0, 0, CGRectGetWidth(tableView.bounds), tableView.sectionHeaderHeight))
label.font = UIFont(name: "HelveticaNeue", size: 14)!
label.text = self.tableView(tableView, titleForHeaderInSection: section)
view.contentView.addSubview(label)

view.textLabel.hidden = true
...

回答4:

Just add [titleLabel setBackgroundColor:[UIColor clearColor]];
because in my case the label overlapped the green color.

Set the back color or background image from this code. Here you don't have to calculate for section height, just set in xib.

-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {

    UIView *sectionView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width,tableView.sectionHeaderHeight)];
    sectionView.backgroundColor = [UIColor greenColor];

    return sectionView;
}
