libC++ abi.dylib：以iOS 7.1上的NSException類型的未捕獲異常終止

Question

我是編程新手。我將用Apple新編程語言Swift學習iOS應用程序開發。 而我按照這個網站（https://developer.apple.com/swift/blog/?id=16）開始。
我將視頻中的代碼複製到我的Xcode項目中。當我在iOS 8.1 iOS模擬器中運行應用程序時，任何事情都很好。
但我在選擇iOS 7.1 iOS模擬器時出現異常。
而我把應用程序放到我的iPhone 5S（iOS 7.1.2）中，它被破壞。

下面是我從視頻複製代碼：

import UIKit 
class ViewController: UIViewController { 
    @IBOutlet weak var photoImageView: UIImageView! 
    let context = CIContext(options: nil) 

    @IBAction func applyFilter(sender: AnyObject) { 
     let inputImage = CIImage(image: photoImageView.image) 

     let randomColor = [kCIInputAngleKey: (Double(arc4random_uniform(314))/100)] 
     let filteredImage = inputImage.imageByApplyingFilter("CIHueAdjust",withInputParameters: randomColor) 
     let renderedImage = context.createCGImage(filteredImage, fromRect: filteredImage.extent()) 

     photoImageView.image = UIImage(CGImage: renderedImage) 
    } 

    override func viewDidLoad() { 
     super.viewDidLoad() 
    } 

    override func didReceiveMemoryWarning() { 
     super.didReceiveMemoryWarning() 
    } 
} 

以下是我從控制檯得到：

我希望有人能幫助我解決這個問題。

通常「無法識別的選擇器發送到實例」（由-doesNotRecognizeSelector產生）表示內存管理問題，通常是仍然引用某處的對象的過度釋放。

我建議你運行帶內存調試的調試版本來分類你的應用程序的內存問題。我建議你通過最新版本的Xcode使用ASan。如果這不是一個選項，你可以使用malloc歷史跟守衛malloc，scribble和NSZombies。
