libC++ abi.dylib：以iOS 7.1上的NSException类型的未捕获异常终止

Question

我是编程新手。我将用Apple新编程语言Swift学习iOS应用程序开发。 而我按照这个网站（https://developer.apple.com/swift/blog/?id=16）开始。
我将视频中的代码复制到我的Xcode项目中。当我在iOS 8.1 iOS模拟器中运行应用程序时，任何事情都很好。
但我在选择iOS 7.1 iOS模拟器时出现异常。
而我把应用程序放到我的iPhone 5S（iOS 7.1.2）中，它被破坏。

下面是我从视频复制代码：

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() 
    } 
} 

以下是我从控制台得到：

我希望有人能帮助我解决这个问题。

通常“无法识别的选择器发送到实例”（由-doesNotRecognizeSelector产生）表示内存管理问题，通常是仍然引用某处的对象的过度释放。

我建议你运行带内存调试的调试版本来分类你的应用程序的内存问题。我建议你通过最新版本的Xcode使用ASan。如果这不是一个选项，你可以使用malloc历史跟守卫malloc，scribble和NSZombies。
