[英]Dismiss UIPopoverPresentationController with any gesture, not just tap
[英]How to dismiss UIPopoverPresentationController on tap inside it. (iOS, Swift)
我已經成功實現了一個popviewcontroller,其中包含4個單元的表格視圖。 我想在選擇單元格時關閉popViewController,但是我似乎無法做到這一點。 在我的tableViewController中,我在didSelectRowAtIndexPath內部有一個方法,該方法將該MasterViewController的方法稱為“ updateToSelectedTab”。 我可以在此處打印出所選單元格的索引路徑,但是當選中該單元格時,我無法刪除popViewController。 我該怎么做呢?
//這是我們的MasterViewController類
@IBAction func pop(sender: AnyObject) {
let contentView = UIStoryboard(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("popViewController") as! PopViewController
contentView.modalPresentationStyle = UIModalPresentationStyle.Popover
contentView.preferredContentSize = CGSizeMake(aButton.frame.width, 240.0)
let popoverMenuViewController = contentView.popoverPresentationController!
popoverMenuViewController.delegate = self
popoverMenuViewController.permittedArrowDirections = UIPopoverArrowDirection.Any
popoverMenuViewController.sourceView = view
popoverMenuViewController.permittedArrowDirections = UIPopoverArrowDirection(rawValue:0)
popoverMenuViewController.sourceRect = CGRectMake(aButton.frame.origin.x, aButton.frame.origin.y - 60, aButton.frame.width, aButton.frame.height)
presentViewController(contentView, animated: true, completion: nil)
}
func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle {
return UIModalPresentationStyle.None
}
//This method is called from didSelectRowAtIndexPath of the View Controller that handles the UIPopoverPresentationController
func updateToSelectedTab(tab: Int){
print("Current tab \(tab)")
//Need to dismiss controller here
}
我要做的就是在索引路徑委托方法的選擇行中添加以下代碼:
dismissViewControllerAnimated(true, completion: nil)
