我已经搜遍了所有并且我找不到可靠的解决方案。 Thankyo

I have searched all over and I haven't found a solid solution. Thankyo

var imagePickerController: UIImagePickerController = UIImagePickerController();
imagePickerController.allowsEditing = true;
imagePickerController.delegate = self;
imagePickerController.sourceType = sourceType;



func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage!, editingInfo: [NSObject : AnyObject]!) {
    profilePictureSelected = true;

    profilePictureImageView.image = image;

    picker.dismissViewControllerAnimated(true, completion: nil);
}

推荐答案

你正确地做到了直到您收到代理回调，在回调中您需要指定它是您要使用的编辑图像。请注意，我在这里使用不同的委托方法。

You are doing it correctly up until you receive your delegate callback, within the callback you need to specify that it's the edited image that you want to use. Please note that i'm using a different delegate method here.

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
    if let chosenImage = info[UIImagePickerControllerEditedImage] as? UIImage {

        profilePictureSelected = true;

        profilePictureImageView.image = chosenImage;
    }
    picker.dismissViewControllerAnimated(true, completion: nil);
}
