I checked the answer button too soon. For some reason this isn't working for me.
I am running on a late 2015 X86_64 iMac with macOS Big Sur 11.5.1 and Xcode 12.5.1. I have my system preferences to use dark mode system wide.
However, when I run this code is does not change the window to .aqua as the documentation states. My assumption is that adding in this .aqua appearance it would override the system. Is that not the case?
import Cocoa
class ViewController: NSViewController {
let greenFilter = CIFilter(name: "CIFalseColor")!
let greenCIColor = CIColor(red: 0.3333, green: 0.8667, blue: 0.0, alpha: 1.0)
let darkGreenCIColor = CIColor(red: 0, green: 0.5373, blue: 0.1137, alpha: 1.0)
let redFilter = CIFilter(name: "CIFalseColor")!
let redCIColor = CIColor(red: 1.0, green: 0.0, blue: 0.0, alpha: 1.0)
let darkRedCIColor = CIColor(red: 0.6275, green: 0.0, blue: 0.0078, alpha: 1.0)
var redFilterColorChange = false
var progressBar: NSProgressIndicator?
var timer = Timer()
override func viewDidLayout() {
NSApp.appearance = NSAppearance(appearanceNamed: .aqua, bundle: nil)
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
self.view.appearance = NSAppearance(named: .aqua)
print("Appearance = \(self.view.appearance!.name)")
let progressFrame = NSRect(x: view.frame.midX-view.frame.width/2+30, y: view.frame.midY-10, width: view.frame.width-60, height: 20)
progressBar = NSProgressIndicator(frame: progressFrame)
self.view.addSubview(progressBar!)
progressBar?.contentFilters = []
if self.view.appearance?.name == .darkAqua {
greenFilter.setValue(darkGreenCIColor, forKey: "inputColor0")
redFilter.setValue(darkRedCIColor, forKey: "inputColor0")
} else {
greenFilter.setValue(greenCIColor, forKey: "inputColor0")
redFilter.setValue(redCIColor, forKey: "inputColor0")
}
// Apply the filter
progressBar?.contentFilters = [greenFilter]
progressBar?.isHidden = false
progressBar?.isIndeterminate = false
progressBar?.doubleValue = 0
progressBar?.maxValue = 1.0
startTimer()
}
override var representedObject: Any? {
didSet {
// Update the view, if already loaded.
}
}
func startTimer() {
print("Starting timer")
timer = Timer.scheduledTimer(timeInterval: 0.1, target: self, selector: #selector(updateProgress), userInfo: nil, repeats: true)
print("Progress bar frame = \(progressBar!.frame)")
}
@objc func updateProgress() {
if progressBar!.doubleValue < 1.0 {
if progressBar!.doubleValue > 0.75 && !redFilterColorChange {
progressBar?.contentFilters = [redFilter]
redFilterColorChange = true
}
progressBar?.doubleValue += 0.01
print("Progress bar value = \(progressBar!.doubleValue)")
} else {
timer.invalidate()
progressBar?.contentFilters = [greenFilter]
progressBar?.doubleValue = 0
progressBar?.isHidden = true
}
}
}
