Global Variable


The clipping rectangle for a thumbnail image.


let UNNotificationAttachmentOptionsThumbnailClippingRectKey: String


The value of this key is a dictionary containing a normalized CGRect—that is, a unit rectangle whose values are in the range 0.0 to 1.0 and represent the portion of the original image that you want to display. For example, specifying an origin of (0.25, 0.25) and a size of (0.5, 0.5) defines a clipping rectangle that shows only the center portion of the image. Use the dictionaryRepresentation function to create the dictionary for your rectangle.
