CFBundleURLSchemes Custom URI Scheme [SOLVED]

[xenon54]

Hi all!

In my OX S application, i need to inbound external interraction.
This is open my app when double click for file with .myapp extensions and open it with custom uri scheme.

For the first case, i found extra simple solution - https://www.tweaking4all.com/forum/delphi-lazarus-free-pascal/lazarus-macos-x-how-to-open-with-for-files-that-open-with-your-application/

For the second case, i found nothing... Can anyone help me with this? I know, that i must register ".myapp" in plist.list by adding this.

Code: Pascal  [Select][+][-]

1.         <key>CFBundleURLTypes</key>
2.         <array>
3.                 <dict>
4.                         <key>CFBundleURLName</key>
5.                         <string>MYAPP</string>
6.                         <key>CFBundleURLSchemes</key>
7.                         <array>
8.                                 <string>myapp</string>
9.                         </array>
10.                 </dict>
11.         </array>
12.  

And application opens by this uri.
But how to parse uri inside application? Somthing like "TForm1.ApplicationProperties1DropFiles" event.

Code: XML  [Select][+][-]

1.         <key>CFBundleURLTypes</key>
2.         <array>
3.                 <dict>
4.                         <key>CFBundleURLName</key>
5.                         <string>MYAPP</string>
6.                         <key>CFBundleURLSchemes</key>
7.                         <array>
8.                                 <string>myapp</string>
9.                         </array>
10.                 </dict>
11.         </array>
12.  

Apple "This key contains the abstract name for this URL type. This is the main way to refer to a particular type. To ensure uniqueness, it is recommended that you use a Java-package style identifier." The highlighted line should therefore be more like:

Code: XML  [Select][+][-]

1. <string>com.yourdomain.myapp</string>

Additionally, you might also consider including:

Code: XML  [Select][+][-]

1. <key>CFBundleTypeRole</key>
2. <string>role</string>

where role is one of: Editor, Viewer, Shell, QLGenerator, None.

[EDIT]

As to the second part of your question, this looks apposite.

Code: Pascal  [Select][+][-]

1. myDocument = objcclass(NSDocument)
2.    public
3.      function getName : NSString; message 'getName';
4.      function getfileURL: NSURL; message 'fileURL';
5.    end;

[xenon54]

Thank you very much for the answer. Can you explain me how to use it?

Code: Pascal  [Select][+][-]

1. myDocument = objcclass(NSDocument)
2.    public
3.      function getName : NSString; message 'getName';
4.      function getfileURL: NSURL; message 'fileURL';
5.    end;
6.  

I'm trying do this

Code: Pascal  [Select][+][-]

1.  
2. type
3.  
4.   myDocument = objcclass(NSDocument)
5.      public
6.        function getName : NSString; message 'getName';
7.        function getfileURL: NSURL; message 'fileURL';
8.      end;
9.  
10. .....
11.  
12. implementation
13.  
14. procedure TForm1.FormCreate(Sender: TObject);
15. begin
16.  
17.   ShowMessage(myDocument.getName);
18.   ShowMessage(myDocument.getfileURL);
19.  
20. end;  
21.  

But getting errors:

Code: Pascal  [Select][+][-]

1. unit1.pas(66,33) Error: Only class methods, class properties and class variables can be accessed in class methods

Looks like this is abstract class and this methods need implementation.

And how to convert NSString to string?
UPD: For this question i find answer:

Code: Pascal  [Select][+][-]

1. uses CocoaUtils;
2.  
3. function NSStringToString(ns: NSString): String;

I discovered a simpler non-macOS API method. Easier to demo than explain

Demo project attached. Opens .xyz files.

Info.Plist to replace default created by Lazarus.

Your demo about open files with custom extension. This is i can ddo.
I need open application by custom URI and parse it when app opened.

Am I misunderstanding?

If you double-click on a  file (you'll need to re-assemble the Info.plist file as the publish project doesn't preserve it), then you can get the filename and path from the FormDropFiles() FileNames[0]. Is that not what you wanted?

How to get filename from double click i know
There is link in my first message to easy way for it.

I need other.
If in browser write "myapp://12345", opens my application. In Application i need to know this string.


I have delphi file, that include what i need (TURLEventHandler), but i cant do this for lazarus.

See https://kaihao.dev/posts/Make-your-own-custom-URI-scheme-resolver

Be warned though - it does not appear to work for me and given that it is a security issue (it has been used by malware in the last couple of years), it's possible it has been "deprecated" out of existence.

I Think this is bad way...
Would be better natively in lazarus.

The first part is easy to resolve in Lazarus by extending the Info.plist file:

Code: XML  [Select][+][-]

1.         <key>CFBundleURLTypes</key>
2.         <array>
3.                 <dict>
4.                         <key>CFBundleTypeRole</key>
5.                         <string>Viewer</string>
6.                         <key>CFBundleURLName</key>
7.                         <string>com.company.SimpleEditor.URLScheme</string>
8.                         <key>CFBundleURLSchemes</key>
9.                         <array>
10.                                 <string>xyz</string>
11.                         </array>
12.                 </dict>
13.         </array>
14.  

So, Safari will then ask you if you want SimpleEditor to open if you give it "xyz://blah".

However, you now need to find a way to actually open the file "blah".

Apple documentation for this.
