ios7 CameraPickerController来自相机的图像已冻结

制作一个pickerDelegate类对我来说很成功。你只需要在构造函数中传递当前的VC,就可以在VC中处理图像。

选取器委派

private class pickerDelegate : UIImagePickerControllerDelegate
        {
            private yourVC _vc;

            public pickerDelegate (yourVC controller) : base ()
            {
                _vc = controller;
            }

            public override void FinishedPickingImage (UIImagePickerController picker, UIImage image, NSDictionary editingInfo)
            {
               //Do something whit the image
                _vc.someButton.SetBackgroundImage (image, UIControlState.Normal);

                //Dismiss the pickerVC
                picker.DismissViewController (true, null);
            }
        }

查看DidLoad

imagePicker = new UIImagePickerController ();

//Set the Delegate and pass the current VC
imagePicker.Delegate = new pickerDelegate (this);
