Best Solution for iOS 9 and above

iOS 9及以上版本的最佳解决方案

This is because of a new feature called readable content guides. It provides margins that are suitable for reading. So, in iPhone and portrait iPad they are very small margins, but in landscape iPad they are bigger. In iOS 9, UITableView's cell margins default to following the readable content guide.

这是因为一种叫做可读内容指南的新特性。它提供适合阅读的边距。因此，在iPhone和竖屏iPad中，它们的利润率很小，但在横向iPad中，它们更大。在ios9中，UITableView的单元格页边值默认遵循可读内容指南。

If you want to stop that, just set the tableView's cellLayoutMarginsFollowReadableWidth to NO/false.

如果您想停止该操作，只需将tableView的celllayout边缘性页面宽度设置为NO/false。

Perfect Solution upto iOS 9

iOS 9的完美解决方案

In viewDidLoad

在viewDidLoad

Objective-C

objective - c

- (void)viewDidLoad {
    [super viewDidLoad];
    //Required for iOS 9
    if ([[[UIDevice currentDevice]systemVersion]floatValue] >= 9.0) {
        self.testTableView.cellLayoutMarginsFollowReadableWidth = NO;
    }
}

Swift

斯威夫特

 override func viewDidLoad() {
    super.viewDidLoad()
    if #available(iOS 9.0, *) {
      tableViewDiet.cellLayoutMarginsFollowReadableWidth = false
    }
  }

In TableViewDelegate methods add following code:

在TableViewDelegate方法中添加以下代码:

Objective-C

objective - c

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {

    // Remove seperator inset
    if ([cell respondsToSelector:@selector(setSeparatorInset:)]) {
        [cell setSeparatorInset:UIEdgeInsetsZero];
    }

    // Prevent the cell from inheriting the Table View's margin settings
    if ([cell respondsToSelector:@selector(setPreservesSuperviewLayoutMargins:)]) {
        [cell setPreservesSuperviewLayoutMargins:NO];
    }

    // Explictly set your cell's layout margins
    if ([cell respondsToSelector:@selector(setLayoutMargins:)]) {
        [cell setLayoutMargins:UIEdgeInsetsZero];
    }
}

Swift

斯威夫特

func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {

    // Remove seperator inset
    if cell.respondsToSelector(Selector("setSeparatorInset:")) {
      cell.separatorInset = UIEdgeInsetsZero
    }

    // Prevent the cell from inheriting the Table View's margin settings
    if cell.respondsToSelector(Selector("setPreservesSuperviewLayoutMargins:")) {
      cell.preservesSuperviewLayoutMargins = false
    }

    // Explictly set your cell's layout margins
    if cell.respondsToSelector(Selector("setLayoutMargins:")) {
      cell.layoutMargins = UIEdgeInsetsZero
    }
  }

A little bit late. I hope is helpful for someone else...

有点晚了。我希望对其他人有所帮助……

if #available(iOS 9.0, *) {
      myTableView.cellLayoutMarginsFollowReadableWidth = false
}

readableContentGuide is a layout guide that is already added to every UIView

readableContentGuide是一个布局指南，已经添加到每个UIView

This is to ensure the user doesn't have to turn his head to read the content.

这是为了确保用户不必转过头来阅读内容。

If you want to follow the readable content guide, then do following:

如果您想要遵循可读的内容指南，那么请执行以下操作:

let baseSection = UIView()

contentView.addSubview(baseSection)

baseSection.translatesAutoresizingMaskIntoCOnstraints= false

let insets = UIEdgeInsets(top: 4, left: 0, bottom: 4, right: 0)

baseSection.leadingAnchor.constraint(equalTo: readableContentGuide.leadingAnchor, constant: insets.left).isActive = true
baseSection.trailingAnchor.constraint(equalTo: readableContentGuide.trailingAnchor, constant: -insets.right).isActive = true
baseSection.topAnchor.constraint(equalTo: contentView.topAnchor, constant: insets.top).isActive = true
baseSection.bottomAnchor.constraint(equalTo: contentView.bottomAnchor, constant: -insets.bottom).isActive = true

Note: In the code above the bottom and top anchors use the contentView instead of the readableContentGuide so that the content vertical margins changes based on the tableView.rowHeight.

注意:在底部和顶部的代码中，使用contentView而不是readableContentGuide，以使内容垂直的边距根据tableview而变化。
