无法从具有NSImage(byReferencingFile:)的文件中加载NSImageView图像 [英] Can not load NSImageView image from file with NSImage(byReferencingFile: )

问题描述

当我要将光盘(/Users/me/Desktop/image.png )中的图像设置为具有NSImage(byReferencingFile: )的NSImageView的图像时，它不会显示.

When I want to set a image from my disc (/Users/me/Desktop/image.png) to the image of my NSImageView with NSImage(byReferencingFile: ) it does not show it.

当我尝试NSImage(named: )使用存储在资产文件夹中的图像进行操作时，它会起作用.

When I try NSImage(named: ) with an image stored in the assets-folder, it works.

viewController中的代码

class ViewController: NSViewController {
    @IBOutlet var imageView: NSImageView!
    override func viewDidLoad() {
        super.viewDidLoad()
        imageView.image = NSImage(byReferencingFile: "/Users/me/Desktop/image.png")
    }    
}

imageView 会填满整个窗口.

所以我想加载存储在磁盘上或指定URL上的图像.

So I want to load the image stored on disk or at a specified URL.
