停止打印NSView [英] Stop NSView from printing

问题描述

我在Xcode中有一个非常基本的Mac应用程序，带有拆分视图，该拆分视图包含PDFThumbnailView和PDFView.(就像预览一样.)

I have a very basic Mac application in Xcode with a Split View that contains a PDFThumbnailView and a PDFView. (Just like Preview.)

除了将PDF加载到视图中所需的代码之外，几乎没有任何Swift代码.

There's hardly any Swift code beyond what is required to load a PDF into the views.

但是，当我从打印"菜单中选择打印"时，除非我先单击PDFView，否则该应用程序要打印ThumbnailView.

However, when I select Print from the Print menu, the app wants to print the ThumbnailView, unless I click on the PDFView first.

有什么办法可以使它始终打印PDFView而不打印ThumbnailView?我认为这是情节提要中某个地方的设置或参数，而不是这样的一些代码.

Is there any way to always make it print the PDFView and never the ThumbnailView? I presume it's a setting or parameter somewhere in the Storyboard, rather than a bit of code as such.

Mojhave 10.14.5上的Xcode 10.2.1.

Xcode 10.2.1 on Mojhave 10.14.5.

推荐答案

一个简单的解决方案是在控制器上以及在XIB文件更改中提供您自己的打印方法(例如 printContent:)打印菜单项的目标方法改为 printContent:而不是 print:

An easy solution would be to provide your own print method (like printContent:) on your controller, and in your XIB file change the target method for the print menu item to printContent: instead of print:

// eg.
@IBOutlet weak var pdfThumbnails: PDFThumbnailView!
@IBOutlet weak var pdfContent: PDFView!

...

@IBAction func printContent(_ sender: Any) {
   self.pdfContent.printView(sender)
}
