NSTextField设置富文本-文本添加点击事件：
来源：http://howtodevelop.eu/question/xcode-swift-with-xcode-8-color-attribute-is-ignored-in-nsattributedstring-with-nslinkattributename,34111
代码：import Cocoa
protocol MyTextFieldDelegate {
func changeNodeClicked()
}
class MyTextField: NSTextField {
var mydelegate: MyTextFieldDelegate?
var referenceView: NSTextView {
let theRect = self.cell!.titleRect(forBounds: self.bounds)
let tv = NSTextView(frame: theRect)
tv.textStorage!.setAttributedString(self.attributedStringValue)
return tv
}
override func mouseDown(with event: NSEvent) {
let point = self.convert(event.locationInWindow, from: nil)
let charIndex = referenceView.textContainer!.textView!.characterIndexForInsertion(at: point)
// if charIndex < self.attributedStringValue.length {
let attributes = self.attributedStringValue.attributes(at: charIndex, effectiveRange: nil)
if let link = attributes[NSLinkAttributeName] as? String ,link=="changeNode"{
// ...
self.mydelegate?.changeNodeClicked()
return
}
// }
super.mouseDown(with: event)
}
}
使用自定义的MyTextField类创建textfield：
let str = NSMutableAttributedString(string: "\(mgr.localizedDescription!) 切换节点")
str.addAttribute(NSLinkAttributeName, value: "changeNode", range: NSMakeRange(str.length-4, 4))
str.addAttribute(NSAttachmentAttributeName, value: NSColor.red, range: NSMakeRange(str.length-4, 4))
self.contentLabel.attributedStringValue = str
实现MyTextField的delegate方法：
extension ViewController: MyTextFieldDelegate {
func changeNodeClicked() {
self.changeNodeFunc() //自定义的点击后函数调用
}
}
