uiimagepickercontroller - 如何在 swift 中使用 UIImagePickerController 捕获相机？

Question

我正在尝试快速使用 UIImagePickerController 但不起作用...

我的 View Controller :

class ViewController: UIViewController {

@IBOutlet var imag : UIView = nil
@IBAction func capture(sender : UIButton) {
    println("Button capture")
    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera)
    {
        var imag = UIImagePickerController()
        imag.delegate = self
        imag.sourceType = UIImagePickerControllerSourceType.Camera;
       imag.mediaTypes = kUTTypeImage
        imag.allowsEditing = false

        self.presentViewController(imag, animated: true, completion: nil)

    }
   }   
}

我在下面的代码行中有错误

imag.delegate = self 
(Type'ViewControlles does confoorm to protocol 'UIImagePickerControllerDelegate')
imagePicker.mediaTypes = kUTTypeImage   
(use of unresolved identifier kUTTypeImage)

我读过 kUTTypeImage 无法在 swift 中使用。但我不知道，我使用的这个函数很糟糕。有帮助吗？

谢谢!!

您还应该在 Controller 中导入 MobileCoreServices:

import MobileCoreServices 

然后像这样将类型放在方括号内:

image.mediaTypes = [kUTTypeImage]

Swift 2.0 及更高版本

image.mediaTypes = [kUTTypeImage as String]
