使用facebook SDK分享文字和图片

如何使用facebook SDK

与预定义文本共享图像

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSString:AnyObject]) {
    guard let image = info[UIImagePickerControllerOriginalImage] as?UIImage else {
    return // No image selected.
}

let photo = Photo(image: image, userGenerated: true)
let content = PhotoShareContent(photos: [photo])
try ShareDialog.show(from: myViewController, content: content)
}
