macOS, Storyboards, Swift.
I have a button to perform a segue to a second page. I can make a control drag from the button to the second page. In Attributes, I have selected a Kind Sheet. Is it possible to open it with a fade in?
To make things easy let's say that:
The first window is ViewController.swift
The second window is SecondViewController
I have button1 in ViewController.swift with segue1 that goes to SecondViewController.swift
OK, here is the complete setup. I tested. May probably be optimized, but that's to show.
0. In the storyboard, I have 2 windowControllers, each with a viewController.
The second window controllr has an Identifier : S1W2
In the first window, I have a button that will call the second window and show with fadeIn.
1. In the VewController file for the FIRST window, define a var for the secondWindowController:
import Cocoa
class ViewController: NSViewController {
var secondWindowController: NSWindowController? // could also be defined outside the class2. Create a button in this VC of First window in the storyboard
No IBOutlet needed
3. Create the fadeIn function in class ViewController:
func fadeInMyWindow() {
print("Starts fade") // Just to check it's called
if self.secondWindowController == nil || self.secondWindowController!.window == nil { return } // Better be cautious
DispatchQueue.main.async { // UI
self.secondWindowController!.window!.alphaValue = 0.0
self.secondWindowController!.window!.makeKeyAndOrderFront(nil)
}
let centiemeSeconde = UInt32(10_000) // Can adjust the fade in speed
for i in 0...99 {
usleep(centiemeSeconde) // I wait 1/100 second to have a visible effect
DispatchQueue.main.async { // UI ;
self.secondWindowController!.window!.alphaValue = CGFloat(i) / 100
}
}
}4. Connect the button to its IBAction from stroyboard to class ViewController ; connection is done by this action, bnot through a segue:
@IBAction func ShowWindowByCode(_ sender: NSButton) {
let storyboard = NSStoryboard(name: "Main", bundle: nil)
if let windowController = storyboard.instantiateController(withIdentifier: "S1W2") as? NSWindowController
{
secondWindowController = windowController
DispatchQueue.global(qos: .userInitiated).async { // Needed for animation to occur
self.fadeInMyWindow()
}
}
}Hope that's clear.
As for fadeOut of your previous post, but competion is different:
completionHandler: {
self.view.window.myWindow.makeKeyAndOrderFront(nil) // Make sure to make it disappear
self.view.window.alphaValue = 1 // For next show of window
}I do it without animator:
var windows (myWindow: NSWindow) // the window to fadeIn
func fadeInMyWindow() {
DispatchQueue.main.async { // UI
self.myWindow.alphaValue = 0.0
self.myWindow.makeKeyAndOrderFront(self.myWindowe)
}
let centiemeSeconde = UInt32(10_000)
for i in 0...99 {
usleep(centiemeSeconde)
DispatchQueue.main.async { // Car c'est une fonction UI ;
self.myWindow.alphaValue = CGFloat(i) / 100
}
}
}I do not understand your code. I am totally lost. Can you explain where do you put each part? What steps do you take?
var myWindow: NSWindow // the window to fadeIn Declared for me as a global
func fadeInMyWindow() {
Is declared as a global func.
When I open ask to display the window :
DispatchQueue.global(qos: .userInitiated).async { // in a thread for animation
self.fadeInMyWindow() // Show it
}Is it clear now ?
I suppose I do not have the necessary level. There are many things I do not understand in your code.
Just to begin: if I put the var it gives me an error: "Class 'ViewController' has no initializers"
Where should that var be? do you do anything before?
class ViewController: NSViewController {
var myWindow: NSWindow
}
OK, I'll show you a more complete set up.
1. I have a NSWindowController subclass
class SomeWindowController: NSWindowController, NSWindowDelegate, NSTextFieldDelegate {2. Defined a window in IB and connected to an IBOutlet in SomeWindowController
@IBOutlet fileprivate weak var myWindow : NSWindow! // Non visible at launch3. In this class, defined a fadeIn func
func fadeInMyWindow() {
DispatchQueue.main.async { // UI
self.myWindow.alphaValue = 0.0
self.myWindow.makeKeyAndOrderFront(self.myWindowe)
}
let centiemeSeconde = UInt32(10_000)
for i in 0...99 {
usleep(centiemeSeconde)
DispatchQueue.main.async { // Car c'est une fonction UI ;
self.myWindow.alphaValue = CGFloat(i) / 100
}
}
}4. On some button tap, I show the window
@IBAction func launch(_ sender: NSButton) {
myWindow.title = NSLocalizedString("MyWindow", comment: "Window") // 18.3.2019
DispatchQueue.global(qos: .userInitiated).async {
self.fadeInMyWindow() // Show window
}
}And that's all.
Sorry, but I still do not understand.
Let's say that I create a new project:
The first window is ViewController.swift
I put a second View Controller from library. I connect that with SecondViewController.swift
I have button1 in ViewController.swift with segue1 that goes to SecondViewController.swift
I suppose the next step is, if I understand what you say, go to Main.storyboard control drag from SecondViewController to ViewController.swift and create an Oulet. Is that right? But if I amb in storyboard SecondViewController and I open the assistant, it will open the SecondViewController.swift not ViewController.swift. How and where do you make that connection of the window?
OK, here is the complete setup. I tested. May probably be optimized, but that's to show.

}
}
}Hope that's clear.
You're not doing yourself any favors trying to learn basics via a never ending forum thread.
Crawl, walk, run. Stop and learn the tool basics first, then jump into baby-stepping a simple app, then come here with questions based on what you learned. Don't run, stumble, fall down, then derp what happened...you'll be falling down for a long time while your goal moves away.
But if you insist, at lease use the Getting Started forum so anyone attempting to help doesn't waste time going over your head.
