TOCropViewController for Xamarin.iOS

Wapps.TOCrop is the Xamarin Binding version of TOCropViewController.

Features

• Crop images by dragging the edges of a grid overlay.
• Optionally, crop circular copies of images.
• Rotate images in 90-degree segments.
• Clamp the crop box to a specific aspect ratio.
• A reset button to completely undo all changes.
• iOS 7/8 translucency to make it easier to view the cropped region.
• The choice of having the controller return the cropped image to a delegate, or immediately pass it to a UIActivityViewController.
• A custom animation and layout when the device is rotated to landscape mode.
• Custom 'opening' and 'dismissal' animations.
• Localized in 18 languages.

Basic Implementation

void Button_TouchUpInside(object sender, EventArgs e)
{
	var cropVC = new TOCropViewController(TOCropViewCroppingStyle.Default, ImageView.Image);
	cropVC.Delegate = new CropVCDelegate ();
	this.PresentViewController(cropVC, true, null);
}

class CropVCDelegate : TOCropViewControllerDelegate
{
	public override void DidCropImageToRect(TOCropViewController cropViewController, CGRect cropRect, nint angle)
	{
		cropViewController.PresentingViewController.DismissViewController(true, null);
		var myImage = cropViewController.FinalImage;
	}
}
