So far WKWebView doesn't have a lot of anything if you're looking at it 
thinking like the WebView. 

From what I could intuit from the small API it offers is that it's intended 
that you do EVERYTHING via JavaScript. 

The good but poorly documented WebKit API is still with us and still really 
capable.

From the fact in the original message that the two variables remained at the 
default of zero my assumption was that neither piece of advice from the 
previous thread on this was followed, those being :-

1) Leave the 'prefer coder' checkbox checked, because it's more consistent, 
arguably fixes a longstanding bug, and remembering when you've turned it on and 
off is likely to lead to confusion. 
2) Don't put initialisation code directly in initWithCoder: but factor it out 
to a separate method called from all the init routines, so it doesn't matter 
which one is called, they all funnel through the same setup code.

Re: Human-understandable process name

[Michael Crawford]

Would it help to examine kernel data structures?

Not everything the kernel does is directly accessible by userspace
frameworks, but within certain limits mostly having to do with
security you can read many kernel data structures.

I don't personally know which ones would help you however this kind of
thing is commonly done.

Apologies. Having just reread that forum post rather than working from what I

Human-understandable process name

[Andrew Keller]

Hello all,

I’m not sure if this is the correct list, but I figure I’ll start somewhere.

I’m writing a program that collects activity statistics on other running 
programs (in particular, network usage statistics).  I have already 
successfully harvested the statistics I want, organized by the PID and name of 
the process, however I’d like to do a better job communicating this information 
to the user.  I am intrigued by Mac OS 10.10’s ability to report “Apps using 
significant energy”; it seems to have the ability to get a commonly understood 
human-readable program name, even when the process in question is a helper app 
with a different name.  Is this ability replicable in third party applications?

Thanks,
 - Andrew Keller

WKWebView +

[patrick machielse]

We're using WKWebView in a OS X application to host a web application.

The web application uses a html element like this to let the user select local 
file paths:



This should display a file dialog. However, it doesn't seem to work with 
WKWebView.


Also, the new WKUIDelegate protocol doesn't seem to have an equivalent to the 
the 'old' WebUIDelegate/WebView method:

- (void)webView:(WebView *)sender 
runOpenPanelForFileButtonWithResultListener:(id)resultListener
 allowMultipleFiles:(BOOL)allowMultipleFiles;


Is there a way to configure WKWebView to make it work correctly with file 
s?

There must be a way, this seems quite basic.

Delete empty Core Data entities from to-many relationship

[Steve Mills]

My model:

Folder:
attributes:
url
relationships:
Relationship: files, Destination: Asset, Inverse: folder, To 
Many, Deny
Relationship: keywords, Destination: Keyword, Inverse: assets, 
To Many, Nullify

Asset:
attributes:
stuff
relationships:
Relationship: folder, Destination: Folder, Inverse: files, To 
One, Nullify

Keyword:
attributes:
stuff
relationships:
Relationship: assets, Destination: Asset, Inverse: keywords, To 
Many, Nullify

When the last Asset that is a member of its Folder is deleted, I want to delete 
the now empty Folder. I added a prepareForDeletion override in Asset:

if(self.folder && self.folder.files.count == 1) {
Folder* fold = self.folder;

if([fold.files containsObject:self])
[self.managedObjectContext deleteObject:fold];
}

This works if I select one asset and delete it. But if I select multiple 
assets, it doesn't work. The count is never 1. It also spits out this:

Is there a better strategy for deleting empty container entities? At first I 
tried setting the Asset's folder relationship to Cascade, but that threw up all 
over.

This depends on whether the "prefer coder" checkbox was checked when the
XIB was authored. If that checkbox is checked, instantiation behaves
like iOS, where custom views get -initWithCoder: instead of
-initWithFrame:.

Re: Connecting a button to MyView zeros integers

[David Duncan]

Since you elided your header file, this begs a question – is this iOS or OS X?

If I’m not mistaken, subclasses of NSView do not get -initWithCoder:, but 
rather -initWithFrame:, which begs the question of have you confirmed that your 
-initWithCoder: method is being called?

I didn't read it that way. Further on down he says "Insertion of  - 
(IBAction)act:(id)sender { } occurs only in my AppDelegate" which I took to 
mean the drag-to-insert-method-stub bit doesn't work. I suggested just adding 
the IBAction by hand in the .h file. I'm not sure I ever tried the auto-add 
method stuff so I have no idea if it works, but I do know typing the IBAction 
code in by hand does and takes about 2 seconds.

The way I read it is he wants an act: method on his MyView and is trying to add 
the method by dragging to the interface/implementation file and is failing to 
get the code inserted into the file, but when he drags to the Delegate object 
then it works, and it also connects it. I also asked if the view he's dragging 
to has its class set correctly to MyView because if it's not, that would 
probably indicate both why the method isn't added by drag and why it can't be 
connected.

 You mean to File's Owner? Is the "Custom Class" of File's Owner set to the 
right class? Both right-drag and ctrl-drag still work for me to connect button 
actions in 6.1.1 (which is the latest on the MAS).

 This is for adding a new outlet/action. I was under the impression you had an 
existing one that you just wanted to hook up?

I'm not sure what you're trying to do. Can you give us a better description? 
Your app delegate has an act: method but you're trying to connect to it by 
dragging to a MyView?
