class ViewController: NSViewController {
@IBOutlet var editView: NSTextView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
let
paragraphStyle = NSParagraphStyle.default().mutableCopy() as! NSMutableParagraphStyle
paragraphStyle.lineHeightMultiple = 1.6
editView.defaultParagraphStyle = paragraphStyle;
//editView.typingAttributes[NSFontAttributeName] = paragraphStyle;
editView.typingAttributes[NSParagraphStyleAttributeName] = paragraphStyle;
}
override var representedObject: Any? {
didSet {
// Update the view, if already loaded.
}
}
}
这是我的所有代码,在main.storyboard中,只有一个NSTextView控件。
但是我的文字被绘制了,而这一切都是从行的底部开始的,这不是我想要的。我希望能够将文本保持在行的垂直位置。我在这方面没有找到案例,请帮我解答。谢谢

您可以使用NSAttributedStringKey.baselineOffset(Swift 3中的NSBaselineOffsetAttributeName)来调整行内文本的垂直位置。您当然需要编写一些代码来计算行高并找到要使用的正确基线,但是这段代码示例应该为您提供基本的想法:
class ViewController: NSViewController {
@IBOutlet var editView: NSTextView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
let paragraphStyle = NSParagraphStyle.default.mutableCopy() as! NSMutableParagraphStyle
paragraphStyle.lineHeightMultiple = 1.6
editView.defaultParagraphStyle = paragraphStyle
editView.typingAttributes[.paragraphStyle] = paragraphStyle
editView.typingAttributes[.baselineOffset] = 15
}
override var representedObject: Any? {
didSet {
// Update the view, if already loaded.
}
}
}
