我有一个简单的Swift类,可以在创建它的XCode 8.1项目中很好地工作(该类中有更多类,但为简洁起见,示例被删减了)。
import UIKit
import AVFoundation
public class ExampleView: UIView {
let captureSession = AVCaptureSession()
var previewLayer : AVCaptureVideoPreviewLayer?
override init (frame : CGRect) {
super.init(frame : frame)
}
convenience init () {
self.init(frame:CGRect.zero)
}
required public init(coder aDecoder: NSCoder) {
fatalError("This class does not support NSCoding")
}
func doSomething(){
print("do something here.....")
}
}
并在viewDidLoad()中使用
let example = ExampleView(frame: self.view.layer.frame);
example.doSomething()
我创建了新的Hyperloop iOS项目(SDK 5.5.1.GA),并将其与关联的appc.js一起添加到src目录中。但是,每次应用程序编译时,我都会达到Hyperloop编译的程度,并且失败,并显示以下内容
[TRACE] : [Hyperloop] metabase took 2243 ms to generate
2016-10-30T15:39:31.675Z | ERROR | An uncaught exception was thrown!
Cannot read property '1' of null
2016-10-30T15:39:31.676Z | ERROR | Cannot read property '1' of null
因此,我然后尝试将此文件添加到hyperloop-examples项目的src目录中,但这也会给我以下错误
[TRACE] : [Hyperloop] metabase took 2425 ms to generate
Swift Generation failed with unknown or unsupported type (AVCaptureSession) found while compiling /Users/accountone/hyperloop-examples/src/MyExample.swift
我在做什么错,以及有关如何解决此问题的建议?
最佳答案
您是否已将AVFoundation
框架添加到appc.js
文件中?
