Hi folks. So I just got a “Mailing list removal confirmation notice” which said the list had received a request from a 17.x.x.x address for the removal of my email address from this list. Anyone else getting something like this? Plot twist: The 17.x.x.x netblock belongs to Apple. “The call is coming from INSIDE THE HOUSE!” Any idea why someone inside Apple wants to pull me off the list?

Re: NSTask: how to launch a binary as if I launched it via terminal?
Colas, Bash’s -c option expects commands in a string which follows. Therefore, this will work: I’m using /usr/bin/touch as an example, rather than your example of pico, which is an interactive text editor. NSTask * myTask = [[NSTask alloc]init]; NSArray * arguments = @[@"-c", @"/usr/bin/touch /Users/colas/touchedFile.txt", @"-l"]; [myTask setCurrentDirectoryPath:@"/"]; [myTask setLaunchPath:@"/bin/bash"]; [myTask setArguments:arguments]; [myTask launch]; This will touch a file named “touchedFile.txt” at the root of your home directory. — Bryan On Apr 14, 2014, at 10:08 AM, Colas B wrote: > OK. > > But without the simple quotes, it also fails. > > With the quotes, the error is > /bin/bash: pico /Users/colas/myfile.txt: No such file or directory > Without the quotes, the error is > Error opening terminal: unknown. > > Thanks! > Le Lundi 14 avril 2014 16h19, Jerry Krinock a écrit : > > From documentation of -[NSTask setArguments:] : > > "The strings in arguments do not undergo shell expansion, so you do not need > to do special quoting” > > I don’t know what they mean by “special”, but anyhow, the ‘ ' you put around > your last argument will be passed to your tool and cause it to fail. > ___ > > Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) > > Please do not post admin requests or moderator comments to the list. > Contact the moderators at cocoa-dev-admins(at)lists.apple.com > > Help/Unsubscribe/Update your Subscription: > https://lists.apple.com/mailman/options/cocoa-dev/bkvines%40me.com > > This email sent to bkvi...@me.com ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: NSTask: how to launch a binary as if I launched it via terminal?
Colas, Do you want your app to open a Terminal window, in which Pico has opened the file at /Users/colas/myfile.txt? If that’s so, I don’t think launching it via NSTask is going to get you anything.

MP4 video playback on Mavericks - Where's a good place to start?
Good morning all, I'm toying with a project to play short video, stored in my app's bundle. I had thought to use QTKit and a QTMovieView, but I can't locate the QTMovieView in Interface Builder. Apple has a QTKit tutorial, "Creating a Simple QTKit Media Player Application," but this is built around Xcode 3.2 and makes use of QTMovieView, which again I'm not seeing. Is AVKit and the AVPlayerView the way to do this in Mavericks? Unfortunately I've only had one cup of coffee today and as a result my Google-fu is weak. I appreciate any guidance as to which way I should go, and where to start looking.

Re: Why IBOutlet don't work under NSTableCellView?
Hello, I'm just beginning to explore view-based tableviews myself. When I build and run this project, Xcode shows two warnings of interest: - Outlet 'ref' of 'My Image' is connected to 'My Reference,' an invalid destination (Objects inside view based table views may only be connected to the table view's delegate.) - Outlet 'delegate' of 'Text Field - Table View Cell' is connected to 'My Reference,' an invalid destination (Objects inside view based table views may only be connected to the table view's delegate.) The linked tutorial, below, has helped me a great deal with regard to view-based tableviews. http://gentlebytes.com/blog/2011/08/30/view-based-table-views-in-lion-part-1-of-2/ Hope that helps! -- Bryan Vines On Oct 30, 2013, at 4:49 AM, 周章林 wrote: > Hi, all, > > I am trying to use NSTableView in our project, and I customized class which > inherit NSImageView, that's MyImage.

Re: Dismissing Open dlog before doc actually opens
Steve, Could you use a boolean property such as fileIsBeingRead? Set that to YES when you start the file read on the background thread, then set it back to NO when the file read has completed. I used this technique in a proof-of-concept app. The app has a status label in its window; the label's value and "hidden" properties are bound to an NSString property and a BOOL property in the app delegate. When the user clicks File > Open, I run the open panel modally [myOpenPanel runModal]. When the user selects a file and clicks the panel's Open button, I set the NSString property something like @"Reading File…" and set the fileIsBeingRead property to YES. Then I call a method to open the file on a background thread. When the "open a file" method finishes reading the file, it resets the NSString and fileIsBeingRead properties, then shows an alert to let the user know the file has been read. You are welcome to the Xcode project for the app I referenced. It's 36K, zipped. TL;DR: You can set a property to indicate the file is being read, and by observing that property, you'll know when the read has finished. Hope that helps. -- Bryan Vines On Aug 13, 2013, at 1:02 PM, Steve Mills wrote: > On Aug 12, 2013, at 21:22:07, Bryan Vines wrote: > >> Can you run an NSOpenPanel with a completion handler block, and in that >> block, call a method on a background thread to actually perform the file >> read operation? > > Well, this won't work.

Re: Dismissing Open dlog before doc actually opens
Steve,
Can you run an NSOpenPanel with a completion handler block, and in that block,
call a method on a background thread to actually perform the file read
operation?
As a test, I put this together. I called the selectAFile method and chose a 4GB
text file. The open panel was dismissed after about a second, the file read
completed after four seconds:
-(void)selectAFile
{
// Get and configure an open panel.
NSOpenPanel * myOpenPanel = [NSOpenPanel openPanel];
[myOpenPanel setCanChooseDirectories:NO];
[myOpenPanel setAllowedFileTypes:[NSArray arrayWithObject:@"txt"]];
// Run the panel.
[myOpenPanel beginWithCompletionHandler:^(NSInteger result)
{
if (result==NSFileHandlingPanelOKButton)
{
// User clicked OK, do the actual file read in a background thread.
[self performSelectorInBackground:@selector(openAFileURL:)
withObject:myOpenPanel.URL];
}
}];
}
-(void)openAFileURL:(NSURL *)aFileURL
{
// Read the contents of the file at aFileURL into a string.
NSString * fileString = [NSString stringWithContentsOfURL:aFileURL
encoding:NSUTF8StringEncoding error:nil];
// Log the result.
if (fileString) {
NSLog(@"Successfully read file: %@", [aFileURL lastPathComponent]);
} else {
NSLog(@"Could not load file: %@", [aFileURL lastPathComponent]);
}
}

Re: full screen
Hi, It sounds like you're saying when the screen resolution changes (in this case, because the Mac mini detects the display), your application stays at whatever resolution the Mac mini defaulted to. So would it be correct to say your application isn't responding to changes in screen resolution? -- Bryan Vines ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
