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.
}
}
}
这是我所有的代码,在main.storyboard中,只有一个NSTextView控件。
但我的文字是画出来的,都是从最下面一行开始的,这不是我想要的。我希望能够保持文本在行的垂直位置。我在这个地区还没有找到病例,请帮我回答。谢谢您
最佳答案
可以使用NSAttributedStringKey.baselineOffset(Swift 3中的NSBaselineOffsetAttributeName)调整文本在行内的垂直位置。当然,您需要编写一些代码来计算行高并找到要使用的正确基线,但此代码示例应为您提供基本思想:
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.
}
}
}
