MacOS App笔记

将全屏按钮设置为+，只能铺满屏幕

self.window?.collectionBehavior = NSWindow.CollectionBehavior.fullScreenAuxiliary

设置NSMenuItem字体颜色

menuitem.attributedTitle = NSAttributedString(string: delete_menuitem.title, attributes: [NSAttributedStringKey.foregroundColor: NSColor.red, NSAttributedStringKey.font: NSFont.systemFont(ofSize: 14)])

播放mp3

import AVFoundation
import MediaPlayer

var audioPlayer: AVAudioPlayer?

let path = Bundle.main.path(forResource: "g_002", ofType: "mp3")
let pathURL = NSURL(fileURLWithPath: path!)
  
do {
   audioPlayer = try AVAudioPlayer(contentsOf: pathURL as URL)
} catch {
    audioPlayer = nil
}

audioPlayer?.prepareToPlay()
audioPlayer?.play()

NSTextView 边距

ContentTextView.textContainerInset = NSSize(width: 10, height: 10)

NSTextView行间距

extension DueWindowController: NSTextStorageDelegate {
    override func textStorageDidProcessEditing(_ notification: Notification) {
        let pa = NSMutableParagraphStyle()
        pa.lineSpacing = 5 //间距值
        let attributes = [NSAttributedStringKey.font:NSFont.systemFont(ofSize: 20),NSAttributedStringKey.paragraphStyle: pa]
        let attr = NSMutableAttributedString(string: self.ContentTextView.string, attributes: attributes)
        self.ContentTextView.textStorage?.setAttributedString(attr)
    }
}

去掉NSScrollView的ScrollerBar

class NoBarScrollView: NSScrollView {

    override func tile() {
        super.tile()
        var hf = self.horizontalScroller?.frame
        hf?.size.height = 0
        self.horizontalScroller?.frame = hf!
        
        var vf = self.verticalScroller?.frame
        vf?.size.width = 0
        self.verticalScroller?.frame = frame
    }
    
}
