AVCaptureDevice.requestAccess() crash
提问by RobertJoseph
I created an iOS single view application using Swift 3.0 and Xcode 8 Beta 2. I am linking with the AVFoundation.framework.
我使用 Swift 3.0 和 Xcode 8 Beta 2 创建了一个 iOS 单视图应用程序。我正在与AVFoundation.framework.
This is my view controller code:
这是我的视图控制器代码：
import UIKit
import AVFoundation
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
if AVCaptureDevice.authorizationStatus(forMediaType: AVMediaTypeVideo) == .notDetermined {
AVCaptureDevice.requestAccess(forMediaType: AVMediaTypeVideo, completionHandler: { (granted: Bool) in
if granted {
print("granted")
}
else {
print("not granted")
}
})
}
}
}
When I run this on my device the app crashes after executing the AVCapture.requestAccessline (the completion handler is not executed and no exceptions are thrown).
当我在我的设备上运行它时，应用程序在执行该AVCapture.requestAccess行后崩溃（未执行完成处理程序，也没有抛出异常）。
The only thing in the Console is:
控制台中唯一的东西是：

Am I doing something wrong?
难道我做错了什么？

Make sure you set a value for the Privacy - Camera Usage Descriptionkey in your Info.plistfile when requesting camera access.
确保在请求访问相机时为文件中的Privacy - Camera Usage Description密钥设置一个值Info.plist。
