出于某种原因，我的页脚与表格重叠，而不是充当页脚，直至底部。这很可能是一个自动布局

var coreView = UIView() //This is the footer
var postBody = UILabel() //This is the label, which will determine the height of the footer.

let nib = UINib(nibName: "MessagesTableViewCell", bundle: nil)
    let 

nibSimple = UINib(nibName: "SimpleMessagesTableViewCell", bundle: nil)
self.tableView.registerNib(nib, forCellReuseIdentifier: "MessagesTableViewCell")
self.tableView.registerNib(nibSimple, forCellReuseIdentifier: "SimpleMessagesTableViewCell")
self.tableView.dataSource = self
self.tableView.delegate = self
self.tableView.rowHeight = UITableViewAutomaticDimension
self.tableView.estimatedRowHeight = 100.0
self.tableView.separatorStyle = UITableViewCellSeparatorStyle.None
self.tableView.separatorColor = UIColor(hex: 0xf5f5f5)
self.tableView.separatorInset = UIEdgeInsetsMake(0, 0, 0, 0)
self.tableView.clipsToBounds = true
self.tableView.allowsMultipleSelection = false
self.tableView.keyboardDismissMode = .OnDrag


    coreView.backgroundColor = UIColor.yellowColor()

    //Create Label and add it to the footer
    postBody.text = "The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy dog."
    postBody.font = UIFont(name: "Roboto-Regular", size: 16.0)
    postBody.lineBreakMode = .ByWordWrapping
    postBody.numberOfLines = 0
    postBody.backgroundColor = FlatLime()
    coreView.addSubview(postBody)

    //Enable constraints for footer and label
    postBody.translatesAutoresizingMaskIntoConstraints = false
    coreView.translatesAutoresizingMaskIntoConstraints = false

    //Add constraints to the footer and post body
    let postBodyLeadingConstraint = NSLayoutConstraint(item: postBody, attribute: NSLayoutAttribute.Leading, relatedBy: NSLayoutRelation.Equal, toItem: coreView, attribute: NSLayoutAttribute.Leading, multiplier: 1, constant: 0)
    postBodyLeadingConstraint.active = true

    let postBodyTrailingConstraint = NSLayoutConstraint(item: postBody, attribute: NSLayoutAttribute.Trailing, relatedBy: NSLayoutRelation.Equal, toItem: coreView, attribute: NSLayoutAttribute.Trailing, multiplier: 1, constant: 0)
    postBodyTrailingConstraint.active = true

    let postBodyTopConstraint = NSLayoutConstraint(item: postBody, attribute: NSLayoutAttribute.Top, relatedBy: NSLayoutRelation.Equal, toItem: coreView, attribute: NSLayoutAttribute.Top, multiplier: 1, constant: 0)
    postBodyTopConstraint.active = true

    let postBodyBottomConstraint = NSLayoutConstraint(item: postBody, attribute: NSLayoutAttribute.Bottom, relatedBy: NSLayoutRelation.Equal, toItem: coreView, attribute: NSLayoutAttribute.Bottom, multiplier: 1, constant: 0)
    postBodyBottomConstraint.active = true

    postBody.preferredMaxLayoutWidth = screenWidth
    self.tableView.tableHeaderView = UIView(frame: CGRectZero)
    self.tableView.tableFooterView = coreView

如您所见，自动布局用于确定页脚 View 的高度(基于标签的高度)。 然而，这是结果。页脚与表格“重叠”，即使我将它设置为最后一行的页脚 View 。

另外:有谁知道为什么coreView右边有一个空白区域？

最佳答案

为什么不尝试将 UITableViewStyle 更改为 Group，我认为它会起作用。

关于ios - 页脚 View 不会粘在 UITableView 的底部，而是与表格重叠(自动布局问题)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/37062669/
