如何从 iOS Xcode 6.1 中的表格视图中删除页眉和页脚

Question

I am unable to remove the header and footer from the grouped table view. I am using Xcode 6.1 and my code is as follows.

- (void)viewDidLoad {
    [super viewDidLoad];

    arr=[[NSArray alloc]initWithObjects:@"Facebook",@"Twitter",@"Linkedin", @"Google+",@"App.net", nil];
    imgView=[[NSArray alloc]initWithObjects:@"fb.png",@"tw.png",@"ln.png",@"em.png", @"em.png", nil];

    self.tableView.layer.borderWidth=1.0;

    self.tableView.tableFooterView=[[UIView alloc]initWithFrame:CGRectZero];
    self.tableView.tableHeaderView=[[UIView alloc]initWithFrame:CGRectZero];

}

Answer 1

Just set them to nil

self.tableView.tableHeaderView = nil;
self.tableView.tableFooterView = nil;

Answer 2

For future visitors returning zero height with heightForHeaderInSection will also get the same results.

func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
    return 0
}

Answer 3

For swift, use this

self.tableView.tableHeaderView = UIView()
