libc++abi.dylib：在 iOS 7.1 上以 NSException 类型的未捕获异常终止

Question

我是编程新手。我将使用 Apple 新的编程语言 Swift 学习 iOS 应用程序开发。 我跟随这个网站（https://developer.apple.com/swift/blog/?id=16）开始。
我将视频中的代码复制到了我的 Xcode 项目中。当我在 iOS 8.1 iOS 模拟器中运行应用程序时，一切都很好。
但是我在选择 iOS 7.1 iOS 模拟器时遇到了异常。
然后我将应用程序放入我的 iPhone 5S(iOS 7.1.2)，它崩溃了。

以下是我从视频中复制的代码：

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()
    }
}

这是我从控制台得到的：

我希望有人能帮我解决这个问题。 （对不起我的英语不好）

Answer 1

通常“发送到实例的无法识别的选择器”（由 -doesNotRecognizeSelector 导致：）表示内存管理问题，通常是过度释放仍在某处引用的对象。

我建议您运行带有内存调试的调试版本，以对应用的内存问题进行分类。我建议您通过最新版本的 Xcode 使用 ASan。如果这不是一个选项，您可以将 malloc 历史记录与 guard malloc、scribble 和 NSZombies 一起使用。
