NSTextfieldが空でない場合はNSButtonを有効にしてください

Question

私はOSXアプリケーションを作成しており、すべてのテキストフィールドが埋められたときにボタンを有効にしたいと考えています。しかし、iosとの違いがあるように、osxアプリの経験はあまりありません。

これは私が試みたものです。

完全なコード：

override func viewDidLoad() { 
    super.viewDidLoad() 

    btnCalculate.enabled = false 

} 

override func controlTextDidChange(obj: NSNotification) { 

    if panelsWideTextField.stringValue.isEmpty { 
     btnCalculate.enabled = false 
    } else { 
     btnCalculate.enabled = true 
    } 
} 

ホープ誰かが

EDIT :-)私のために良いヒントを持っています。

私は同じ問題を抱えていたが、私は簡単な解決策を見つけた：checkboxはNSButtonを有効または無効にすることができます。

import Cocoa 

class ViewController: NSViewController { 

    @IBOutlet weak var btnCalculate: NSButton! 
    @IBOutlet weak var checkBox: NSButton! 


    override func viewDidLoad() { 
     super.viewDidLoad() 
     btnCalculate.enabled = false 
     checkBox.state = 0 
    } 

    @IBAction func checkAgree(sender: NSButton) { 
     if btnCalculate.stringValue.characters.count > 0 && checkBox.state == 1 { 
      btnCalculate.enabled = true 
     } else { 
      btnCalculate.enabled = false 
     } 
    } 
}
