xcode7 - 无法将 '[CFString]' 类型的值分配给 '[String]' 类型的值

Question

我刚刚下载了新的 Xcode 7 beta 5，但找不到解决此错误的方法。它一直突出显示“pickker.mediaTypes = [kUTTypeImage]”行并说“无法将类型为 '[CFString]' 的值分配给类型为 '[String]' 的值”

if (UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera)){
        let picker = UIImagePickerController()
        picker.delegate = self
        picker.sourceType = UIImagePickerControllerSourceType.Camera
        picker.mediaTypes = [kUTTypeImage]
        picker.allowsEditing = true
        self.presentViewController(picker, animated: true, completion: nil)
    }
    else{
        NSLog("No Camera.")
    }

Answer 1

尝试将 CFString 转换为字符串，如下所示:

picker.mediaTypes = [kUTTypeImage as String]
