怎么在iPhone上查看PDF

使用Safari、Chrome或“邮件”应用程序时，iPhone会自动打开PDF文件。你可以将PDF文件保存到“图书”应用程序，以便随时查看。也可以从任何网站下载PDF文件，保存邮件中的PDF副本，或通过iTunes将电脑上的PDF文件同步到手机上。

步骤

使用Safari

1. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/0\/0e\/Read-PDFs-on-an-iPhone-Step-1-Version-6.jpg\/v4-460px-Read-PDFs-on-an-iPhone-Step-1-Version-6.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/0\/0e\/Read-PDFs-on-an-iPhone-Step-1-Version-6.jpg\/v4-728px-Read-PDFs-on-an-iPhone-Step-1-Version-6.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 1 点击链接以打开PDF文件。Safari应用程序原生支持PDF文件。点击链接后就会在浏览器中显示PDF文件。
2. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/8\/8a\/Read-PDFs-on-an-iPhone-Step-2-Version-6.jpg\/v4-460px-Read-PDFs-on-an-iPhone-Step-2-Version-6.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/8\/8a\/Read-PDFs-on-an-iPhone-Step-2-Version-6.jpg\/v4-728px-Read-PDFs-on-an-iPhone-Step-2-Version-6.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 2 用双指缩放页面。在Safari查看PDF时，可以像浏览其他网站一样使用双指缩放页面。双指张开可放大页面，捏合可缩小页面。
3. {"smallUrl":"https:\/\/www.zenmeban.com\/images_en\/thumb\/2\/2a\/Read-PDFs-on-an-iPhone-Step-3-Version-6.jpg\/v4-460px-Read-PDFs-on-an-iPhone-Step-3-Version-6.jpg","bigUrl":"https:\/\/www.zenmeban.com\/images\/thumb\/2\/2a\/Read-PDFs-on-an-iPhone-Step-3-Version-6.jpg\/v4-728px-Read-PDFs-on-an-iPhone-Step-3-Version-6.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"} 3 长按以选择文字。如果要复制PDF中的文字，可以长按屏幕。出现放大镜图标时松开手指，然后拖动标记以选择文字。
   • 有些PDF的生成方式不同，可能无法或很难选择文字。

   • 在Safari中点击正在查看的PDF。
   • 点击出现的“在‘图书’中打开”按钮。如果已安装其他PDF阅读器，点击更多按钮，然后选要使用的阅读器。
   • 在“图书”或PDF阅读器中查看PDF。如果在“图书”中打开，文件将被存储在此应用程序及iCloud云盘中，方便你随时查看。
