NSImageView (added programmatically) doesn't show image, but shows color
Swift 4. Very simple project, all I did - just added a NSImageView
programmatically, backgroundColor
and NSImage
from the .jpg file. I see the good pink color, but can't see the image at all! I tried many different approaches and some was successful (Image showed up well in collection view and if NSImageView
was added manually in the story board) but I need in simple programmatically method. Here is all of my code:
class ViewController: NSViewController {
var image: NSImage = NSImage()
var ivTest = NSImageView()
override func viewDidLoad() {
super.viewDidLoad()
self.view.addSubview(self.ivTest)
self.ivTest.wantsLayer = true
self.ivTest.layer?.backgroundColor = NSColor.systemPink.cgColor
self.ivTest.layer?.frame = NSRect(x: 0, y: 0, width: 100, height: 100)
let manager = FileManager.default
var url = manager.urls(for: .documentDirectory, in: .userDomainMask).first
url = url?.appendingPathComponent("night.jpg")
image = NSImage(byReferencing: url!)
if (image.isValid == true){
print("valid")
print("image size (image.size.width):(image.size.height)")
self.ivTest.image = image
} else {
print("not valid")
}
}
override var representedObject: Any? {
didSet {
// Update the view, if already loaded.
}
}
}
output:
result:
thank so much...

As Willeke mentioned, your frame is not configured in your code. set frame for ivTest or use autolayout to give ivTest size.
