ios – CFString在Swift 2.0和XCODE 7中为kUTTypeImage转换为String

我得到一个错误转换CFString.错误信息是：

Cannot assign a value of type ‘[CFString]’ to a value of type ‘[String].

怎么修？

picker.sourceType = UIImagePickerControllerSourceType.Camera
picker.allowsEditing = false
picker.mediaTypes = [kUTTypeImage] //Error Message : Cannot assign a value of type '[CFString]' to a value of type '[String]'
picker.delegate = self
picker.modalPresentationStyle = .Popover
presentViewController(picker,animated: true,completion: nil)//

解决方法

从头文件：

public var mediaTypes: [String]
// default value is an array containing kUTTypeImage.

所以你实际上可以删除那一行.

但是如果你想保留它,你只需要明确表示你想要一个演员：

picker.mediaTypes = [kUTTypeImage as String]
