Add a post build script to launch something?

Look in build phases.

Re: loadNibNamed deprecated, but newer version crashes

[Charles Srstka]

What’s the crash? Is it an exception? If so, what’s the description that gets 
posted to the console?

FWIW I just tried one of those .dmgs here on 10.12 and it behaved as expected.

loadNibNamed deprecated, but newer version crashes

[Gabriel Zachmann]

I would like to replace this line of code:
[NSBundle loadNibNamed: @"ConfigureSheet" owner: self];

by the newer version loadNibNamed: owner:topLevelObjects:.

This runs in a screensaver. The deprecated version (loadNibNamed:owner:) works.
The new version causes a crash.
Here are the variants I have tried:

1.

NSBundle * bundle = [NSBundle bundleForClass:[self class]];
NSArray * nibArray = nil;
[bundle loadNibNamed: @"ConfigureSheet" owner: self topLevelObjects: ];

2.

NSBundle * bundle = [NSBundle bundleForClass:[self class]];
[bundle loadNibNamed: @"ConfigureSheet" owner: self topLevelObjects: nil;

3.

[[NSBundle mainBundle] loadNibNamed: @"ConfigureSheet" owner: self 
topLevelObjects: nil];



I must be missing something.

I have checked the API docs, but I didn't see any hints. I have googled 
extensively, to no avail.

Any hints, pointers, suggestions will be highly appreciated.

Best regards, 
Gabriel.

Hi Jonathan. I don’t know the answer, but I do have a related question :)

Has /Applications moved or changed on 10.12?

I have the classic .dmg approach to installation, where a disk image includes 
an alias for /Applications and the user drags the app icon to it. On 10.12, the 
alias appears to point to nothing, and has a generic file icon. Has this kind 
of installer image been obsoleted by 10.12? If so, what can we do to replace it 
in a way that works across various OS versions?

Package installation on MacOS Sierra

[Jonathan Mitchell]

Hi

I have a MacOS package that installs into /Applications on 10.11.
On 10.12 it appears to install into the user’s Downloads folder.

Is this change related to the new feature in MacOS 12 to encapsulate downloaded 
apps into a read only container?

Thanks

Re: Triggering a segue from code

Most of the problem is that storyboards and segues for the Mac are inadequately 
documented. This is exacerbated by the fact that understanding the behavior “by 
analogy with iOS” breaks down when windows are involved, since there’s no such 
thing (AFAIK) as a segue between windows on iOS.

By trial and error, I discovered that the problem in your sample project is 
that a “show” segue from a view controller does not open a new window. This 
halfway makes sense, although the fact that it does nothing and produces no 
exception or log message is pretty unhelpful. (Bug report!)

To get the button to display the panel, you need to have the window controller 
perform the segue. That means you’ll need a custom window controller subclass 
for the main window, and you can just move the action method into the window 
controller. (Hook the button up to First Responder instead of the view 
controller, too.)

Alternatively, go back to using a segue from the button to open the panel, 
which IIRC was working in an earlier version of this test project. (You posted 
that it wasn’t working, but when I went to look at your project you’d already 
fixed the problem in your project that was preventing it from working. IIRC.)

To do all the combinations of hiding and showing a singleton panel, you’ll 
probably want another custom window controller subclass for the panel itself. 
Not every window/window controller operation seems to be mapped into storyboard 
semantics, so you should expect that there are things that still need to be 
done “the old way”.

Triggering a segue from code

[mail...@ericgorr.net]

For reference, I have a sample project location at 

https://github.com/ericgorr/nspanel_show

It is a Document Based and Storyboard application.

On my main window, I have a toolbar with an Toolbar Item called 'Inspector'. I 
have defined a segue between this item and my Inspector Utility Panel called 
"Show Inspector". When I press the Inspector toolbar item, the utility panel 
does show as expected. I can close the panel by pushing the standard window 
close button.

What I would like to do is trigger my "Show Inspector" segue when I push the 
"Show Panel" button. I have tried the code:

@IBAction func showMyPanel( _ sender: AnyObject )
{
NSLog( "How do I show the panel?" )

self.performSegue( withIdentifier: "Show Inspector", sender: self )

}
   
While I do see the log message 'How do I..', my utility panel is not shown.

How can I get this work?

Here is an image that shows the basic setup in Interface Builder.

Your understanding matches mine. (I don’t work on the team that manages
NSToolbar, so I will let them have the final say in the response to your
bug report.) In the meantime, I would go with option #2.

 Sure! Pick "Edit Scheme..." from the target selection popup in your Xcode 
window's toolbar. There, select the "Run" entry on the left. In the "Info" tab, 
you can set the executable to run to any executable in your project, or another 
arbitrary one.

You could try  adding a run shell script phase at the end of the compilation to 
substitute the executable.

Have you looked at or tried CATextLayer? It already does all of this internally 
- you just have to set up its font, size, string, etc.

Since you’re drawing this into a CALayer anyway, I think you’re going to lose 
the sub-pixel antialiasing that you get using Core Graphics. I think (but maybe 
misremembered) that CATextLayer does something to ensure that works. But even 
if it doesn’t, it’ll still be a better option than replicating its 
functionality.

How to make Xcode launch a different app when "Running" my code?

[Gabriel Zachmann]

When I "Run" my code in Xcode (i.e., hit CMD-R), I would like Xcode to build 
the code, copy the product to its destination,
and then run a *different* application, not the product it has built.
(all on macOS, not iOS)

Does anyone know how that is possible?

I haven't found it in Xcode's documentation, and couldn't find a hint with 
Google.
I am using Xcode 7.3.1.

Thanks a lot in advance.

Best regards, 
Gabriel.

Re: Replacement for CGContextSelectFont ?

[Gabriel Zachmann]

Dear Graham, dear Alex, dear Will,

thanks a lot for your helpful suggestions. 

So far, I have written this code as a replacement for CGContextSelectFont().
I am putting it here for the record (i.e., Google's archives).
But if anyone could suggest modifications to make it better (e.g., remove a 
bug, make it simpler, or more future proof),
I will greatly appreciate it.


Best regards, 
Gabriel.
