Question

我有以下代码，允许UIButton捕获部分屏幕截图并将其保存到相机胶卷 - 谢谢Lou Franco：）

    // Declare the snapshot boundaries
    let top: CGFloat = 100
    let bottom: CGFloat = 60

    // The size of the cropped image
    let size = CGSize(width: view.frame.size.width, height: view.frame.size.height - top - bottom)

    // Start the context
    UIGraphicsBeginImageContext(size)

    // we are going to use context in a couple of places
    let context = UIGraphicsGetCurrentContext()!

    // Transform the context so that anything drawn into it is displaced "top" pixels up
    // Something drawn at coordinate (0, 0) will now be drawn at (0, -top)
    // This will result in the "top" pixels being cut off
    // The bottom pixels are cut off because the size of the of the context
    CGContextTranslateCTM(context, 0, -top)

    // Draw the view into the context (this is the snapshot)
    view.layer.renderInContext(context)
    let snapshot = UIGraphicsGetImageFromCurrentImageContext()

    // End the context (this is required to not leak resources)
    UIGraphicsEndImageContext()

    // Save to photos
    UIImageWriteToSavedPhotosAlbum(snapshot, nil, nil, nil)

我如何修改上述代码，以便：

另一个UIButton可以捕获相同的部分屏幕截图并将其作为附件EMAIL？和
另一个UIButton可以捕获相同的部分屏幕截图并将其作为附件发送短信吗？

我意识到我的问题可能让我看起来很懒惰，不是这样，我现在只是非常环保：）

我已经尝试过搜索网络并修改各种代码段，但我真的很难过！

非常感谢提前。非常感谢您的时间和精力！

以下代码将为您设置电子邮件图像。

let composer = MFMailComposeViewController()
composer.setToRecipients(["someemail@email.com"])
composer.setMessageBody("Body", isHTML: false)
composer.setSubject("Subject")

let imageData = UIImagePNGRepresentation(snapshot)
composer.addAttachmentData(imageData, mimeType: "image/png", fileName:"myImage")

presentViewController(composer, animated: true, completion: nil)

要将其作为短信发送，它几乎完全相同，除非您使用MFMessageComposeViewController而不是MFMailComposeViewController

电子邮件截图，不保存到相机胶卷
