I have a toolbar button
#IBOutlet weak var testButton: NSToolbarItem!
The button call a popover and works fine.
But if i try and call the popover from a top menu item i get a crash.
I have amended the location of the popover to appear below the testButton just as it normally would. (commented below)
#IBAction func menuPreviewAndTestAction(sender: AnyObject) {
var returnedHtmlString = checkEverythingAndCreateTheEncodedHtml(testButton)
setEncodedHtmlToPreview(returnedHtmlString)
var thebounds = self.testButton.view?.bounds // so i am givving bounds of button that narmally calls poover
testingPopover.showRelativeToRect(thebounds!, ofView: sender as NSView, preferredEdge: NSMaxYEdge) // crashes
}
Oh dear... I missed changing the ofView, all sorted with :
var thebounds = self.testButton.view?.bounds
var theview = self.testButton.view
testingPopover.showRelativeToRect(thebounds!, ofView: theview! as NSView, preferredEdge: NSMaxYEdge)

I have a UITextView
#IBOutlet weak var note: UITextView!
note.delegate = self
The text view is inside of a UIScrolLView
#IBOutlet weak var scrollView: UIScrollView!
That I am trying to get to respond to this:
// move the scrollView when the keyboard is presented
NotificationCenter.default.addObserver(self, selector: #selector(Keyboard), name: Notification.Name.UIKeyboardWillHide, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(Keyboard), name: Notification.Name.UIKeyboardWillChangeFrame, object: nil)
that when pressed called this function:
#objc func adjustForKeyboard(_ notification: Notification) {
let userInfo = notification.userInfo!
let keyboardScreenEndFrame = (userInfo[UIKeyboardFrameEndUserInfoKey] as! NSValue).cgRectValue
let keyboardViewEndFrame = view.convert(keyboardScreenEndFrame, from: view.window)
if notification.name == NSNotification.Name.UIKeyboardWillHide {
scrollView.contentInset = UIEdgeInsets.zero
} else {
scrollView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: keyboardViewEndFrame.height, right: 0)
}
scrollView.scrollIndicatorInsets = scrollView.contentInset
}
What I want to happen is when you tap on the UITextView, if the keyboard is going to hide the text view, the content is scrolled up, so that the TextView is always visible. This method works just fine for my UITextFields, but it's not working for the UITextView.
Followed this tutorial, and still not working for me. I'm not sure if he is using UITextView or UITextFields in the video, I think Fields.

How to adjust a UIScrollView to fit the keyboard
I have a UIWebView in my ViewController and a navigation controller embedded in my ViewController. In my navigation controller, I selected "Show Toolbar" and "Hide Bars on Swipe" but the Toolbar doesn't hide. It only works when "Show Navigation Bar" is selected with the Toolbar.
Is there anyway to have the Toolbar hide on swipe when scrolling down the UIWebView?
Thank you in advanced.
You can use UIScrollViewDelegate for that.
Here is example code for hide navigation bar and tool bar with scroll:
import UIKit
class ViewController: UIViewController, UIScrollViewDelegate {
#IBOutlet weak var toolBar: UIToolbar!
#IBOutlet weak var webV: UIWebView!
var lastOffsetY :CGFloat = 0
override func viewDidLoad() {
super.viewDidLoad()
webV.scrollView.delegate = self
let url = "http://apple.com"
let requestURL = NSURL(string:url)
let request = NSURLRequest(URL: requestURL!)
webV.loadRequest(request)
}
//Delegate Methods
func scrollViewWillBeginDragging(scrollView: UIScrollView){
lastOffsetY = scrollView.contentOffset.y
}
func scrollViewWillBeginDecelerating(scrollView: UIScrollView){
let hide = scrollView.contentOffset.y > self.lastOffsetY
self.navigationController?.setNavigationBarHidden(hide, animated: true)
toolBar.hidden = hide
}
}
I am trying to open a new window in my Swift application but I cannot get it to open.
class AppDelegate: NSObject, NSApplicationDelegate
{
func applicationDidFinishLaunching(aNotification: NSNotification)
{
openMyWindow()
}
func openMyWindow()
{
if let storyboard = NSStoryboard(name: "Main",bundle: nil)
{
if let vc = storyboard.instantiateControllerWithIdentifier("MyList") as? MyListViewController
{
var myWindow = NSWindow(contentViewController: vc)
myWindow.makeKeyAndOrderFront(self)
let controller = NSWindowController(window: myWindow)
controller.showWindow(self)
}
}
}
}
I have set the Storyboard ID in IB.
I have traced the code and it does get into the window opening code but it doesn't do anything.
BTW I do have a default storyboard entry point set and that default window opens OK but I need to have a second window open and that is what is not working.
After the openMyWindow() method is executed, the windowController will be released and consequently the window is nil. That's why it is not there.
You have to hold the window in you class to keep it alive, then the window will be visible.
var windowController : NSWindowController?
I have an NSPopover connected to the NSView of a window. Currently I have a NSStatusItem that displays a NSStatusMenu. When you click a certain option in that menu I set the menu to nil and then display the NSPopover. The problem is I want the status bar button to remain highlighted when the NSPopover is displayed, but it only flashes highlight when I click the button to open the NSPopover. I have tried statusItem.button?.highlight(true) to no avail, and it seems changing the button type does not do anything either. Any ideas? Thanks. Also, any way to make the NSView inside the popover or more specifically the text field in the NSView selected once the NSPopover is opened? I have the popover behavior set to transient but it will only close if you click on the popover first, then outside the popover.
#IBOutlet weak var mainMenu: NSMenu!
#IBOutlet weak var popover: NSPopover!
#IBOutlet weak var popoverView: NSView!
#IBOutlet weak var textField: NSTextField!
// init new menu bar item
let statusItem = NSStatusBar.systemStatusBar().statusItemWithLength(-1)
func applicationDidFinishLaunching(aNotification: NSNotification) {
// init menu bar item icon
let icon = NSImage(named: "menuIcon")
icon?.setTemplate(true) // now compatible with "dark mode"
statusItem.image = icon
statusItem.menu = mainMenu
popover.behavior = NSPopoverBehavior.Transient
//statusItem.button?.setButtonType(NSButtonType.OnOffButton)
}
#IBAction func StatusItemClicked(sender: NSButton) {
if !(popover.shown) {
popover.showRelativeToRect(sender.bounds, ofView: statusItem.button!, preferredEdge: NSMinYEdge)
}
else {
popover.close()
}
}
#IBAction func movieRegular(sender: NSMenuItem) {
statusItem.menu = nil // get rid of statusItem menu
statusItem.action = Selector("StatusItemClicked:") // func StatusItemClicked called when button clicked
StatusItemClicked(statusItem.button!) // call it so popover immediately displays first time
}
I have this code that opens up a popover element at the "sender" location, i.e. the button that was pressed. How can I make this function call when a statusItem is clicked, so that the popover comes down from the status/menu bar?
#IBAction func togglePopover(sender: AnyObject) {
if !(popoverIsOpen) {
myPopover.showRelativeToRect(sender.bounds, ofView: popoverButton, preferredEdge: NSRectEdge(3))
popoverIsOpen = true
}
else {
myPopover.close()
popoverIsOpen = false
}
}
I am currently using NSPopover and NSStatusItem.
edit: The changelog for Xcode 6 beta 4 added NSStatusItem.button and softly deprecated the previous form of calls like NSStatusItem.action, NSStatusItem.title, NSStatusItem.target, etc.
The documentation now reads
NSStatusItem.button
The button that is displayed in the status bar. This is created automatically on the creation of the StatusItem. Behavior customization for the button, such as image, target/action, tooltip, can be set with this property.
I was able to reach an implementation shown below, using the new NSStatusBarButton visual representation of an NSStatusBarItem. In this example, my .xib file has the NSPopover element already connected to a view, which isn't shown here.
#IBOutlet weak var myPopover: NSPopover!
var statusBar: NSStatusItem!
var popoverIsOpen = false
#IBAction func togglePopover(sender: AnyObject) {
if !(popoverIsOpen) {
myPopover.showRelativeToRect(sender.bounds, ofView: statusBar.button, preferredEdge: NSRectEdge(3))
popoverIsOpen = true
}
else {
myPopover.close()
popoverIsOpen = false
}
}
func applicationDidFinishLaunching(aNotification: NSNotification?) {
//initialize menu bar icon
statusBar = NSStatusBar.systemStatusBar().statusItemWithLength(CGFloat(48))
statusBar.button.title = "Your App Title"
statusBar.button.appearsDisabled = false
statusBar.button.action = Selector("togglePopover:")
statusBar.button.target = self
}
