如何将UIImage快速传递给iOS中的Today扩展？

Question

Is there a way to pass UIImage over to Today Extension using NSSharedDefaults in such way? :

if let sharedDefaults = NSUserDefaults(suiteName: "group.example.TodayExtension") {
    // Below line crashes, since .setObject cannot have UIImage as a parameter
    sharedDefaults.setObject(image, forKey: "imageKey") // image = UIImage object
    sharedDefaults.synchronize()
}

Convert the image to a NSData object with UIImageJPEGRepresentation . Store the NSData object in NSUserDefaults . In the extension get back the image with imageWithData(_:) .
