Reducing the space between sections of the UITable

Question

Is there a way to reduce the space between two sections of a UITableView? There are about 15 pixels between every single section I have. I did already try to return 0 for -tableView:heightForFooterInSection: and -tableView:heightForHeaderInSection: but that doesn't change anything.

Any suggestions?

Answer 1

You can actually set the footer/header/cell heights in Interface Builder under the size tab. By default the header/footer are set at 10.0.

Answer 2

UPDATE FOR iOS7: Due to ARC autorelease update, here's @Martin Stolz code edited.

-(CGFloat)tableView:(UITableView*)tableView heightForHeaderInSection:(NSInteger)section
{
    if(section == 0)
        return 6;
    return 1.0;
}

-(CGFloat)tableView:(UITableView*)tableView heightForFooterInSection:(NSInteger)section
{
    return 5.0;
}

-(UIView*)tableView:(UITableView*)tableView viewForHeaderInSection:(NSInteger)section
{
    return [[UIView alloc] initWithFrame:CGRectMake(0, 0, 0, 0)];
}

-(UIView*)tableView:(UITableView*)tableView viewForFooterInSection:(NSInteger)section
{
    return [[UIView alloc] initWithFrame:CGRectMake(0, 0, 0, 0)];
}

(Using iOS7, Xcode v5.0)

You can also reduce the height of section footer and header from the storyboard. In the tableview -> size inspector. Go to Section Height.

By default it is set to 22 for Plain style table and 10 for grouped style table. You can configure values by increasing / decreasing the values for header and footer separately.

Answer 4

For me the issue was because I was using a grouped table view style (UITableViewStyleGrouped). When I changed it to a plain style (UITableViewStylePlain) my tableView:heightForHeaderInSection: method was the only thing determining the size of each section header.

Answer 5

For me just this issue got resolved just by using the following code,

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    return section == 0 ? 1 : 20 // 20 is my other sections height
}

Returning 1 for the first section has solved the issue.

Answer 6

Use this perhaps, 0 will not work as expected

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
     return .leastNormalMagnitude
}

func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
    return .leastNormalMagnitude
}
