blocks|key|4516629|text|你可以通过迭代所有的pdf然后一个接一个地解锁来做到这一点。我不确定你是否确实在寻找这种类型的解决方案，但可能会有所帮助。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4516630|遍历所有的pdf并通过传递pdf的确切路径创建一个CGPDFDocument，CGPDFDocumentRef上有一个方法可以检查文档是否受密码保护，它是"CGPDFDocumentIsUnlocked".。如果文件已锁定，则使用method:"CGPDFDocumentUnlockWithPassword".解锁该文件|offset|length|style|BOLD|4516631|将解锁的文档保存到路径中，从那时起，您不必在每次访问它时都解锁。|4516632|TNQ|4516633|entityMap^0|0|26|N|3F|V|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@$D|P|E|Q|F|G]|$D|R|E|S|F|G]]|9|@]|A|$]]|$1|H|3|I|5|6|7|T|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|U|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|M|$]]

You can do it in a way by iterating through all the pdf's and unlocking one by one.I am not sure if you are exactly looking for this type of solution, but may be helpful.

Iterate through all the PDf's and create a CGPDFDocument by passing the exact path of the pdf,
there is a method on CGPDFDocumentRef to check whether the document is password protected, which is "CGPDFDocumentIsUnlocked". If it is locked then unlock the file using the method:"CGPDFDocumentUnlockWithPassword".

save the unlocked document to a path and from then on you need not unlock each time you access it.

This is what i tried:-
<ol>
<li>Open the PDF file.
</li>
<li>Enter the password for the first time.
</li>
<li>Now to remove password &quot;ctrl+p&quot;, then select this <a href="https://i.stack.imgur.com/ROCIO.png." rel="nofollow noreferrer">&quot;Microsoft Print To PDF&quot;</a>.
</li>
</ol>
<ol start="4">
<li>Then click on print,it will ask for location to save, give the details where you want to save and save it.
</li>
<li>Done.
</li>
</ol>
<h2>Note:-</h2>
<ol>
<li>To be more precise we don't need any browser for this it can be done in your local system.
</li>
<li>Sometime you get some bank documents like form-16 etc, it will be password protected and you will not be having permission to modify due to security reason, due to some reason or might be you are using some organization system, so in that case this is helpful.
</li>
</ol>

I have a bunch of pdf's I want to remove passwords from. Note that I know the password, so no need for brute forcing. I am working on a mac, so I would like to make an app to remove those passwords. 

I have seen apps like wondershare's pdf password remover, so I know it is possible.

Is there a solution/library in the obj-c environment to remove passwords from PDF's?

我有一堆我想删除密码的pdf文件。请注意，我知道密码，所以不需要暴力破解。我在mac上工作，所以我想做一个应用程序来删除这些密码。我见过像wondershare的pdf密码删除程序这样的应用，所以我知道这是可能的。在obj-c环境中是否有一个解决方案/库可以从PDF中删除密码？
