如何在swift中使用UIImagePickerController捕获相机？ [英] how to capture camera with UIImagePickerController in swift?

问题描述

我正在尝试在swift中使用 UIImagePickerController 但是不能正常工作...

I'm trying use UIImagePickerController in swift but isn't work...

我的ViewController：

my ViewController:

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)

    }
   }   
}

我在以下代码行中有错误

I have errors in following line of code

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。但是不知道，我使用的是这个函数。有什么帮助？

I have read that kUTTypeImage cant use in swift.but don't know, i am using bad this functions. Any help?

谢谢!!

推荐答案

你还应该导入控制器中的MobileCoreServices：

You should also import MobileCoreServices in the controller:

import MobileCoreServices 

然后将类型放在方括号内，如下所示：

and then put the type inside square brackets like this:

image.mediaTypes = [kUTTypeImage]

Swift 2.0及更高

image.mediaTypes = [kUTTypeImage as String]
