PROSAGA码农传奇-swift/objective-C-使用PMPrintSession时使用系统对话框打印

<div class =“post-text”itemprop =“text”>
  <P>
    你可以运行一个
     <code>
      NSPrintPanel
    </code>
     显示系统打印对话框。为此，您还需要设置一个
     <code>
      NSPrintInfo
    </code>
     宾语：
  </p>
   <pre>
    <code>
      NSPrintInfo* printInfo = [NSPrintInfo new];
// set printInfo.printer if you want to override the default

PMPrintSettings printSettings = printInfo.PMPrintSettings;
// configure printSettings
[printInfo updateFromPMPrintSettings];

PMPageFormat pageFormat = printInfo.PMPageFormat;
// configure pageFormat
[printInfo updateFromPMPageFormat];

</code>
  </pre>
  <P>
    创建面板并使用该信息对象运行它：
  </p>
   <pre>
    <code>
      NSPrintPanel* panel = [NSPrintPanel printPanel];
// configure panel; for example, set its options property
NSInteger result = [panel runModalWithPrintInfo:printInfo];

</code>
  </pre>
  <P>
    使用信息作为打印会话的基础：
  </p>
   <pre>
    <code>
      if (result == NSOKButton)
{
    PMPrintSession session = printInfo.PMPrintSession;
    printSettings = printInfo.PMPrintSettings;
    pageFormat = printInfo.PMPageFormat;
    PMSessionBeginCGDocumentNoDialog(session, printSettings, pageFormat);
    PMSessionBeginPageNoDialog(session, pageFormat, NULL);
    CGContextRef lGraphics;
    PMSessionGetCGGraphicsContext(session, &lGraphics);

...

PMSessionEndPageNoDialog(session);
    PMSessionEndDocumentNoDialog(session);
}

</code>
  </pre>
</DIV>
