在静态 UITableViewCell 中显示 UIButton 的弹出框

Question

当我点击 UIButton 时出现弹出框。此按钮位于静态 UITableViewCell 中。但是，当我点击按钮时，弹出框不在我认为应该在 UIButton 下的位置。

因为它是一个静态单元格，所以我没有使用 didSelectRowAtIndexPath，也不需要使用 cellForRowAtIndexPath。我基本上使用 UITableView 作为在我的视图控制器中嵌入滚动视图的廉价替代方案。它本质上是用于数据输入的。我有 4 个部分，每个部分有 1 行。我相信我需要弄清楚如何从每个部分的行中获取 NSIndexPath 以传递给 .sourceView 类似于 Objective-C 中的内容

UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
[self.profileItemsDetailPopover presentPopoverFromRect:cell.bounds inView:cell.contentView permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];


@IBAction func dateOfBirthAction(sender: AnyObject){

    var popoverViewController = self.storyboard?.instantiateViewControllerWithIdentifier("DateOfBirthViewController") as UIViewController
    popoverViewController.modalPresentationStyle = .Popover
    popoverViewController.preferredContentSize   = CGSizeMake(300, 300)

    let popoverPresentationViewController = popoverViewController.popoverPresentationController

    popoverPresentationViewController?.permittedArrowDirections = .Any
    popoverPresentationViewController?.delegate = self
    popoverPresentationViewController?.sourceView = tableView
    popoverPresentationViewController?.sourceRect = playerInformationBirthDateButton.frame

    presentViewController(popoverViewController, animated: true, completion: nil)
}

解决方案：

@IBAction func dateOfBirthAction(sender: UIButton){

    var cell = sender.superview!.superview! as UITableViewCell

    var popoverViewController = self.storyboard?.instantiateViewControllerWithIdentifier("DateOfBirthViewController") as UIViewController
    popoverViewController.modalPresentationStyle = .Popover
    popoverViewController.preferredContentSize   = CGSizeMake(300, 300)

    let popoverPresentationViewController = popoverViewController.popoverPresentationController

    popoverPresentationViewController?.permittedArrowDirections = .Any
    popoverPresentationViewController?.delegate = self
    popoverPresentationViewController?.sourceView = cell.contentView
    popoverPresentationViewController?.sourceRect = playerInformationBirthDateButton.frame

    presentViewController(popoverViewController, animated: true, completion: nil)
}

您还可以在单​​击按钮时找到“单元格”。

var cell = sender.superview!.superview! as UITableViewCell
// or the table
var table: UITableView = cell.superview as UITableView
// or the Indexpath
let indexPath = table.indexPathForCell(cell)
