G'天,
我创建了一个带有NSTextField和按钮的简单Swift应用程序。 NSTextField通过viewDidLoad方法预加载了一些文本。
我想双击并突出显示单行文本,然后在按下按钮时将该行读入变量。这应该是直截了当的,但我甚至无法接近,我找不到像这一样简单的任何其他问题。
有人可以帮忙吗?

class ViewController: NSViewController {
@IBOutlet weak var myTextField: NSTextField!
@IBAction func readTheTextField(sender: AnyObject) {
println("Read button pushed.")
// I need some code in here.
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
myTextField.stringValue += "To be or not to be.\n"
myTextField.stringValue += "That is the question.\n"
myTextField.stringValue += "Whether tis nobler in the mind,\n"
myTextField.stringValue += "to suffer the slings and arrows of outrageous fortune."
}
override var representedObject: AnyObject? {
didSet {
// Update the view, if already loaded.
}
}
}

查看NSScanner类,特别是scanUpToCharactersFromSet方法。你给它一个换行符,并让它一次扫描一行到另一个字符串。
