我正在使用 Eureka 框架和最近添加的代码以允许边到边的单元格分隔符。这样一来，所有表单元素都需要定义边距，否则它们会从屏幕的最左侧开始。

有没有办法像调整单元格一样调整节页眉/页脚的左/右页边距？我试图避免为每个部分/标题标题使用自定义类。

我试着查看源代码以查看 View 是如何创建的，但我没有看到它定义 x 坐标或左/右边距等的任何地方。我也没有看到任何属性可以设置来实现这一点。

如有任何帮助，我们将不胜感激!

            +++ Section(){section in
                var footer = HeaderFooterView<UITableViewHeaderFooterView>(.Class)
                footer.onSetupView = {view, _, _ in
                    view.preservesSuperviewLayoutMargins = false
                    view.layoutMargins.left = 50
                    view.layoutMargins.right = 50
                    view.contentView.preservesSuperviewLayoutMargins = false
                    view.contentView.layoutMargins.top = 10
                    view.contentView.layoutMargins.left = 50
                    view.textLabel?.text = "This is a test footer message."
                    view.textLabel?.layoutMargins.top = 10
                    view.textLabel?.font = UIFont.preferredFontForTextStyle("Footnote")
                }
                section.header = HeaderFooterView<ALogoView>(HeaderFooterProvider.Class)
                section.footer = footer
                }

编辑:我已经尝试了上面的方法，但它不起作用。如果您输入一个长字符串，它会向上移动到父部分的行中。

Edit2:我想出了以下内容

class GenericHeader: UIView {

override init(frame: CGRect) {
    super.init(frame: frame)
    self.preservesSuperviewLayoutMargins = false
    let textView = UILabel()
    textView.frame = CGRect(x: 0, y: 0, width: UIScreen.mainScreen().bounds.width - 30, height: 20 )
    textView.text = "This is  a very very very long title, This is  a very very very long title, This is  a very very very long title, This is  a very very very long title, This is  a very very very long title, This is  a very very very long title Let's add some more stuff here to see how it handles."
    textView.numberOfLines = 0
    textView.textAlignment = .Justified
    textView.font = UIFont.preferredFontForTextStyle(UIFontTextStyleBody)
    textView.textColor = UIColor(red:0.47, green:0.47, blue:0.49, alpha:1.0)
    textView.frame = textView.bounds
    textView.sizeToFit()
    self.addSubview(textView)
    //self.frame = CGRect(x: -15, y: -3, width: textView.bounds.width - 16, height: textView.bounds.height)
    self.bounds = CGRect(x: -15, y: -3, width: textView.bounds.width - 16, height: textView.bounds.height)
}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}
}

我在我的表单中使用这个:

+++ Section() {
    $0.header = HeaderFooterView<GenericHeader>(HeaderFooterProvider.Class)
    $0.footer = HeaderFooterView<GenericFooter>(HeaderFooterProvider.Class)
}

当 Header/Footer 类被实例化时，我如何传递一个字符串，这样我就不必用不同的文本编写一百万个不同的类/ View ？

最佳答案

我通过在每一行中执行此操作添加了表格 View 单元格边距....

TextRow.defaultCellSetup = { cell, row in
    cell.preservesSuperviewLayoutMargins = false
    cell.layoutMargins.left = 0
    cell.contentView.preservesSuperviewLayoutMargins = false
    cell.contentView.layoutMargins.left = 50
}

ButtonRow.defaultCellSetup = { cell, row in
    cell.preservesSuperviewLayoutMargins = false
    cell.layoutMargins.left = 0
    cell.indentationLevel = 5
}
