I have a NSViewController named Hardness, and I need not to let user resize it. Of course, I can just resize it back every time the users tries, but is there any way just not to let user open a window to full screen, or to stretch the window?
edit/update: Xcode 10.2 • Swift 5
NSWindow has a property called styleMask that allows you to control what kinds of control will be available to the user. If you don't want to allow the user to resize the window you have to remove the style mask .resizable using the mutating method remove(member: NSWindowStyleMask). To enable it again you need to use the mutating method insert(member: NSWindowStyleMask). Note that it will also disable the full screen mode for that window:
removing to disable:
window.styleMask.remove(.resizable)
inserting to enable
window.styleMask.insert(.resizable)
Sample
import Cocoa
class ViewController: NSViewController {
#IBOutlet weak var closable: NSButton!
#IBOutlet weak var miniaturizable: NSButton!
#IBOutlet weak var resizable: NSButton!
#IBOutlet weak var titled: NSButton!
lazy var window: NSWindow! = self.view.window
func remove(_ member: NSWindow.StyleMask) {
window.styleMask.remove(member)
}
func insert(_ member: NSWindow.StyleMask) {
window.styleMask.insert(member)
}
#IBAction func toggle(_ sender: NSButton) {
switch sender.state {
case .on:
switch sender {
case closable: insert(.closable)
case miniaturizable: insert(.miniaturizable)
case resizable: insert(.resizable)
case closable: insert(.closable)
case titled: insert(.titled)
default: break
}
case .off:
switch sender {
case closable: remove(.closable)
case miniaturizable: remove(.miniaturizable)
case resizable: remove(.resizable)
case closable: remove(.closable)
case titled: remove(.titled)
default: break
}
default: break
}
}
}
Sample Project
I solved the same issue with the non-resizable window by one line of code in
override func viewDidAppear() {
self.view.window?.styleMask.remove(NSWindowStyleMask.Resizable)
}
The correct approach would be to use bitwise operators.
Disable resize:
window?.styleMask &= ~NSResizableWindowMask
Enable resize:
window?.styleMask |= NSResizableWindowMask
This answer may be of some help in addition to the current one. There's also a nice simple way to accomplish this by using setHidden with NSWindowZoomButton
Setup the functionality as a sub-class of NSWindow:
Objective-C
#import "CustomWindow.h"
#implementation CustomWindow
- (void)awakeFromNib {
NSButton *zoomButton = [self standardWindowButton:NSWindowZoomButton];
[zoomButton setHidden:YES];
}
#end
Swift
import CustomWindow
class CustomWindow {
func awakeFromNib() {
var zoomButton: NSButton = self.standardWindowButton(NSWindowZoomButton)
zoomButton.setHidden(true)
}
}
Connect the custom class to your window in IB and the Zoom button should be now hidden!
A little more elegant solution for Swift 3, so that the | operator can be used:
public func | (left: NSWindowStyleMask, right: NSWindowStyleMask) -> NSWindowStyleMask {
return NSWindowStyleMask(rawValue: left.rawValue | right.rawValue)
}

I created a custom keyboard screen on tvOS.
If possible, tap on UITextField as it is, I want to transition to the custom keyboard view.
But tapping the UITextField always displays the system keyboard.
What should I do now?
1) Make the view controller implement this delegate: UITextFieldDelegate
class YourViewController: UIViewController, UITextFieldDelegate {
// ...
yourTextField.delegate = self
// ...
}
2) Return false in textFieldShouldBeginEditing, so the text field doesn't respond and the keyboard doesn't open. Instead, open yours or do whatever you want.
func textFieldShouldBeginEditing(_ textField: UITextField) -> Bool {
// HERE, open your keyboard or do whatever you want
return false
}
textField.inputView = UIView()
class YourViewController: UIViewController,UITextFieldDelegate { }
First set your delegate for textfieldtextField.delegate = self, Then
func textFieldDidBeginEditing(_ textField: UITextField) {
textField.addTarget(self, action: #selector(gettextFieldFunction), for: UIControlEvents.touchDown)
}
I have been experimenting with mouse clicks. I am ok with left mouse clicks getting raw values etc etc. I now want to add right mouse clicks. I have setup a basic example. What i would like to achieve if there is one mouse right click it performs one function, and if there is two mouse right clicks it performs a different function. The problem is if you do two mouse clicks it obviously cannot differentiate between the two and so fire the one mouse click function before performing the second mouse function.
I was thinking of maybe using a timer of some sort to record the number of click. But i end up going round in circles as i just seem to start the timers over and over. I'm hoping some one might help. thanks for reading here is the code.

//Initialize mouse for Right Click numberOfClicksRequired = 1

recogRightClick1.numberOfClicksRequired = 1
MyView.addGestureRecognizer(recogRightClick1)
//Initialize mouse for Right ClicknumberOfClicksRequired = 2
let recogRightClick2 = NSClickGestureRecognizer(target: self, action: #selector(twoMouseClick(myrec:myRightClick:)))
recogRightClick2.buttonMask = 0x2
recogRightClick2.numberOfClicksRequired = 2
MyView.addGestureRecognizer(recogRightClick2)
}//EO Overide
func oneMouseClick(myrec: NSPanGestureRecognizer,myRightClick:NSClickGestureRecognizer){
let rightClick = myRightClick.state.rawValue
print("oneMouseClick",rightClick)

func twoMouseClick(myrec: NSPanGestureRecognizer,myRightClick:NSClickGestureRecognizer){
let rightClick = myRightClick.state.rawValue
print("twoMouseClick",rightClick)
}
}//EnD oF thE wORld
UPDATE
I have re generated the code following the advice given. Now the code reflects more of what i wanted to do. My only problem is that I would like all the mouse operations to be triggered only inside 'myView' rather than within the main window. I thought it might have something to do with first responder but that doesn't seem to work. Again any thought would be appreciated. Please excuse any bad code i'm self taught.

UPDATE 2
I have now updated subClassing the view controller, so the mouse clicks are now only working in myView. I'm still having problems with 'func mouseDragged' What i need to achieve is the bottom left of my view is x = 0 and Y = 0. I had a try with converting but thats not working. hoping someone might guide me. thanks for reading here is the updated code.

Swift.print("mouseDown")
}
override func mouseUp(with theEvent: NSEvent) {

To define mouse inside view you use
let myLocationInWindow = theEvent.locationInWindow
let location = convert(myLocationInWindow, from: nil)
where nil is the window
here is the final code

class MainWindowController: NSWindowController {

I am building an OS X desktop app that allows a user to select an item from a dropdown. I am trying to create an NSPopupButton menu like the response to this question, which is also very similar to this tutorial, but when I build and run in Xcode, I get an EXC_BAD_INSTRUCTION error and the NSPopupButton evaluates to nil in the debugger. Did I miss a step initializing the menu? I also have a text input, but it works just fine. My code:
import Cocoa
class ViewController: NSViewController {
#IBOutlet weak var textInput: NSTextField!
#IBOutlet weak var myMenu: NSPopUpButton!
// other stuff here for processing textInput
#IBAction func selectFromMyMenu(sender: NSPopUpButton) {
let selection = myMenu.titleOfSelectedItem
if selection == "Second Option" {
// do something
} else {
// do something else - first option is default
}
}
func setupMyMenu() {
let menuItems = ["First Option", "Second Option"]
myMenu.removeAllItems()
myMenu.addItemsWithTitles(menuItems)
myMenu.selectItemAtIndex(0)
}
override func viewDidLoad() {
super.viewDidLoad()
setupMyMenu()
}
override var representedObject: AnyObject? {
didSet {
// Update the view, if already loaded.
}
}
}
Try reconnecting your button from the storyboard to your ViewController code.
I am new to Mac OSX and with Apple promoting the fact that the bodies of code are becoming similar decided to tell the folk I am writing code for we should be able to do a Mac OSX version. iPhone and iPad versions are all good and about to release second version so no issues there.
So I am subclassing NSWindowController to get access to the Toolbar and worked out how to remove and add items on the toolbar, but for the life of me I can not get one NSViewController (firstViewController) to dismiss and bring up the second NSViewController (secondViewController) in the same NSWindowController.
So the 2 issues are that
1. I want to be able to performSegueWithIdentifier from the first NSViewController in code and
2. bring up the second NSViewController by replacing the first NSViewController in the same NSWindowController.
If I add a button to the firstViewController and put a segue to the secondViewController then when I select the button the secondViewController comes up just fine but in a seperate window not the same NSWindowController that I want it to and the firstViewController does not get replaced but stays in the NSWindowController.
So I know the segue idea will work but its not working in code and when I do insert the segue from a button it works but into a seperate NSViewController that is not part of the NSWindowController.
I am trying to find some programming guide from Apple on the issue but no luck so far.
Here is an overview from my Storyboard:
Here is my NSWindowController subclassed and the func loginToMe2Team is trigger from the NSToolBar and its working just find as the print statements show up on the console.
import Cocoa
class me2teamWindowsController: NSWindowController {
#IBOutlet var mySignUp : NSToolbarItem!
#IBOutlet var myToolbar : NSToolbar!
let controller = ViewController()
override func windowDidLoad() {
super.windowDidLoad()
print("window loaded")
}
override func windowWillLoad() {
print("window will load")
}
#IBAction func logInToMe2Team(sender: AnyObject){
controller.LogIn() //THIS IS THE FUNC I AM TESTING WITH
}
#IBAction func signUpToMe2Team(sender: AnyObject){
controller.signUp()
}
Here is my NSViewController subclassed with the func LogIn. Its getting selected just fine but the performSegueWithIdentifier is not. And I did cut and past the Identifier to make absolutely sure it was the same.
import Cocoa
import WebKit
class ViewController: NSViewController {
#IBOutlet weak var theWebPage: WebView!
#IBOutlet weak var progressIndicator: NSProgressIndicator!
override func viewDidLoad() {
super.viewDidLoad()
let urlString = "https://thewebpage.com.au"
self.theWebPage.mainFrame.loadRequest(NSURLRequest(URL: NSURL(string: urlString)!))
}
override func viewDidAppear() {
}
func LogIn() {
print("I logged in")
self.performSegueWithIdentifier("goToTeamPage", sender: self)
//THIS IS THE BIT THATS NOT WORKING
}
func signUp() {
print("I have to sign up now")
}
override var representedObject: AnyObject? {
didSet {
}
}
func webView(sender: WebView!, didStartProvisionalLoadForFrame frame: WebFrame!)
{
self.progressIndicator.startAnimation(self)
}
func webView(sender: WebView!, didFinishLoadForFrame frame: WebFrame!)
{
self.progressIndicator.stopAnimation(self)
}
}
You need to use a custom segue class (or possibly NSTabViewController if it’s enough for your needs). Set the segue’s type to Custom, with your class name specified:
…and implement it. With no animation, it’s simple:
class ReplaceSegue: NSStoryboardSegue {
override func perform() {
if let src = self.sourceController as? NSViewController,
let dest = self.destinationController as? NSViewController,
let window = src.view.window {
// this updates the content and adjusts window size
window.contentViewController = dest
}
}
}
In my case, I was using a sheet and wanted to transition to a different sheet with a different size, so I needed to do more:
class ReplaceSheetSegue: NSStoryboardSegue {
override func perform() {
if let src = self.sourceController as? NSViewController,
let dest = self.destinationController as? NSViewController,
let window = src.view.window {
// calculate new frame:
var rect = window.frameRectForContentRect(dest.view.frame)
rect.origin.x += (src.view.frame.width - dest.view.frame.width) / 2
rect.origin.y += src.view.frame.height - dest.view.frame.height
// don’t shrink visible content, prevent minsize from intervening:
window.contentViewController = nil
// animate resizing (TODO: crossover blending):
window.setFrame(window.convertRectToScreen(rect), display: true, animate: true)
// set new controller
window.contentViewController = dest
}
}
}
Im simply trying to make it so when I click on a UIButton (for which it currently shows the image of a shell), the image changes into something else (in this case, a coin).
This is what i tried so far and have not had any success. I cant find anything to do this for Swift.Thanks.
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var lblOutput: UILabel!
#IBOutlet weak var lblWin: UILabel!
#IBOutlet weak var lblLost: UILabel!
#IBOutlet weak var lblWinsAmt: UILabel!
#IBOutlet weak var lblLossesAmt: UILabel!
let coin = UIImage(named: "penny_head") as UIImage;
override func viewDidLoad() {
super.viewDidLoad()
//imgShell1.hidden = true //doesnt work
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
#IBAction func btnStart(sender: UIButton) {
}
#IBAction func btnShell1(sender: UIButton) {
sender.setImage(coin,forState: UIControlState.Highlighted);
}
The way you're setting up the control is incorrect. Assuming you have a button property named btnShell (and it's the button you want to setup) change your viewDidLoad() method to:
override func viewDidLoad()
{
super.viewDidLoad()
btnShell.setImage(imgShell1, forState:.Normal);
btnShell.setImage(coin, forState:.Highlighted);
}
And then remove the setImage(_:forState:) call from the action method:
#IBAction func btnShell1(sender: UIButton) {
sender.setImage(coin,forState: UIControlState.Highlighted);
}
To permanently change the button image on tap, you have to use the .Normal enum case and not .Highlighted for the control state:
sender.setImage(coin,forState: UIControlState.Normal)
Setting the image for the .Highlighted state makes the new image appear only when the button is in that state, i.e. when it is tapped.
If you are looking to change the UIButton's background image permanently you have to use Antonio's method:
sender.setImage(coin,forState: UIControlState.Normal)
This won't change the UIKit's default highlighting when you tap the button. When you don't want the button to be highlighted when you touch it or have different appearances for different states, then you might be better off using an UIImageView.
In viewDidLoad():
imgView?.image = imgOne
imgView?.userInteractionEnabled = true
imgView?.addGestureRecognizer(UITapGestureRecognizer(target: self, action: "changeImage:"))
The function that changes the image:
func changeImage(recognizer: UITapGestureRecognizer){
self.imgView?.image = imgTwo
}
You can also use isSelected.
button.setImage(image2, for: .normal)
button.setImage(image1, for: .selected)
