每當我嘗試使用rangeOfString它說成員沒有在UITextView中找到

Question

import UIKit 

class ViewController: UIViewController { 
    @IBOutlet weak var text: UITextView! 

    override func viewDidLoad() { 
     super.viewDidLoad() 

     let boldRange = text.rangeOfString(NSLocalizedString("bold", comment: "")) 
     // issue is here. 
    } 

    override func didReceiveMemoryWarning() { 
     super.didReceiveMemoryWarning() 
     // Dispose of any resources that can be recreated. 
    } 
} 

每當使用rangeOfString我碰到這個問題，但我不知道如何解決它。

您需要訪問文本視圖的text屬性：

let boldRange = text.text.rangeOfString(NSLocalizedString("bold", comment: ""))
