为UIImagePicker添加循环裁剪组件？ [英] Add a circular cropping component for UIImagePicker?

问题描述

我有一个圆形框架 UIImageView ，我需要为 UIImagePickerController 添加一个圆形框架裁剪工具从照片库中选择图像。非常类似于Instagram的 UIImagePicker的裁剪组件。如何添加此类组件？

更新

我是使用圆形裁剪工具

并且我的裁剪视图中的按钮被禁用，这意味着我无法选择它们。调试器中继的是什么消息对我来说？

这是我的代码：

  @IBAction func chooseProfilePicture（sender：AnyObject）{
 
 var myPickerController = UIImagePickerController（）
 myPickerController = UIImagePickerController（）
 myPickerController.delegate = self; 
 myPickerController.sourceType = UIImagePickerControllerSourceType.PhotoLibrary 
 
 self.presentViewController（myPickerController，animated：true，completion：nil）
} 
 
 func imagePickerController（picker） ：UIImagePickerController，didFinishPickingMediaWithInfo info：[NSObject：AnyObject]）{
 
 var image：UIImage =（info [UIImagePickerControllerOriginalImage] as？UIImage）！ 
 
 editProfilePictureImageView.image = image 
 
 self.dismissViewControllerAnimated（false，completion：{（） - > Void in 
 
 var imageCropVC：RSKImageCropViewController！ 
 
 imageCropVC = RSKImageCropViewController（image：image，cropMode：RSKImageCropMode.Circle）
 
 imageCropVC.delegate = self 
 
 self.navigationController？.pushViewController（ imageCropVC，动画：true）
 
}）
 
} 
  

解决方案

I Have a circular framed UIImageView and I need to add a circular framed cropping tool for the UIImagePickerController, after the image is selected from a photo library. Very similar to Instagram's UIImagePicker's crop component. How do I add this type of component?

UPDATE

I've found this repo with a circular cropping tool https://github.com/ruslanskorb/RSKImageCropper

but can someone guide me on to how to implement this cropping tool with the UIImagePickerController after the user selects a photo from the photo library?

UPDATE

I am getting the following message in my debugger :

and the buttons in my crop view are disabled, meaning I cannot select them.. what message is the debugger relaying on to me?

here is my code:

  @IBAction func chooseProfilePicture(sender: AnyObject) {

        var myPickerController = UIImagePickerController()
        myPickerController = UIImagePickerController()
        myPickerController.delegate = self;
        myPickerController.sourceType = UIImagePickerControllerSourceType.PhotoLibrary

        self.presentViewController(myPickerController, animated: true, completion: nil)
    }

    func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {

        var image : UIImage = (info[UIImagePickerControllerOriginalImage] as? UIImage)!

        editProfilePictureImageView.image = image

        self.dismissViewControllerAnimated(false, completion: { () -> Void in

            var imageCropVC : RSKImageCropViewController!

            imageCropVC = RSKImageCropViewController(image: image, cropMode: RSKImageCropMode.Circle)

            imageCropVC.delegate = self

            self.navigationController?.pushViewController(imageCropVC, animated: true)

        })

    }

解决方案

Example Demo

Yes you can add RSKImageCropper in your UIImagePickerController

define imagePicker

var imagePicker : UIImagePickerController!

in ViewDidLoad

    imagePicker = UIImagePickerController()
    imagePicker.delegate = self
    imagePicker.sourceType = UIImagePickerControllerSourceType.PhotoLibrary;
    self.presentViewController(imagePicker, animated: true, completion: nil)

Delegate methode :

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject])
{

    var image : UIImage = (info[UIImagePickerControllerOriginalImage] as? UIImage)!

    picker.dismissViewControllerAnimated(false, completion: { () -> Void in

        var imageCropVC : RSKImageCropViewController!

        imageCropVC = RSKImageCropViewController(image: image, cropMode: RSKImageCropMode.Circle)

        imageCropVC.delegate =self

        self.navigationController?.pushViewController(imageCropVC, animated: true)

    })

}
