UTI for Mach-O file
Hello. I'm implementing an NSDocument-based utility that loads mach-o files and displays information about them. But no matter what UTI I put in the Info.plist, I can't get the app to recognize the file when dropped on the dock tile. The only way I could get it recognized is by having no UTI and a * for the extensions, but this has the (very) unfortunate side-effect of recognizing ALL files. I've tried com.apple.mach-o.binary and public.unix-executable as well as public.executable. It's curious, because running mdls shown no UTI for an executable... Can anyone tell me the best way to go from here, so that my app recognizes ONLY mach-o files? Is UTI's even the best way to go?

Re: UTI for Mach-O file
I guess that makes sense. But then why is there a com.apple.mach-o.binary and a public.unix-executable UTI in the first place?? Well, technically, UTIs are not just applied to on-disk files. They can be applied to email attachments, where a MIME type might give that sort of information (although perhaps not for those specific UTIs). Also, pasteboard contents. But mostly, I'm guessing they exist as parent UTIs for other more-specific UTIs to declare conformance with. You can use the UTTypeCopyDeclaration and/or UTTypeCopyDeclaringBundleURL on those UTIs to investigate. Maybe the declaration includes some file extensions, for example. So, there might be real files that get assigned com.apple.mach-o.binary or public.unix-executable based on a file extension neither of us is thinking of right now. Of course, that doesn't help solve your problem, just maybe satisfy your curiosity. :) Yes, it does satisfy my curiosity. Thanks for your knowledge and insight. I guess it would've just been oh-too-convenient if that little dock icon highlighted only for valid mach-o files and bundles... But it's just aesthetics; the program will function doing it like Kevin suggested.

Re: Sanity Check
I have taken all advice and the code now looks like below which cleans up the
pointed out controller leak and does not store [self window]:
There still seems to be some problems with your code...
- (IBAction)sewing:(id)sender {
[[[SewingController alloc] initWithWindowNibName:@Sewing and Color
andBFileName:mBFilename] release];
}
You allocate and immediately release the controller here... not quite sure what
you're trying to do here, but that basically means you don't have a controller
object, and your window will not stay onscreen. Have you actually tested this
code?
- (id) initWithWindowNibName:(NSString*)windowNibName
andBFileName:(BFilename*)bfilename
{
self = [super initWithWindowNibName:windowNibName];
if (self != nil)
{
[self retain];
m_design = [[self window] contentView];
[[self window] setDelegate:self];
}
return self;
}
Once again, no point in hanging on to the content view and storing it in an
ivar, because just like the window, it's easily accessible from -window
-contentView. Unless it's a custom view, but I do not see a cast here... Also,
do you have a reason for retaining self?
- (void)windowWillClose:(NSNotification *)notification {
if(m_design-m_dirtyDesign)
NSLog(@dirty message);
else
NSLog(@clean, no message);
[self release];
}
This -release is interesting as
well.___

Re: Custom bundle icon
You should do as Jean-Daniel says, but also, you should set the 'bundle bit' of your .ftplugin files. The system only knows to show .ftplugin folders as flat files if it can find your UTI somewhere. If the user has your app, then that's fine, but if not then he'll still see a folder. Thanks for the info on the bundle bit. So can I set the UTI on the plugin itself, or must I set it on the main app? I mean, I understand that setting it on the main app will work, but will setting it on just the plugin work as well?___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Custom bundle icon
You can't set a UTI on something. You provide a UTI declaration in your Info.plist, consisting of a set of attributes that define what it means for a file to conform to a UTI, and Launch Services uses that to match files against when it tries to determine their UTI. So, no, by definition you can't set it on your plugin bundle. Did you instead mean you wanted to provide your UTI declaration in your plugin bundle's Info.plist? That won't work, unforunately. The Declaring New Uniform Type Identifiers section of the Uniform Type Identifiers Overview enumerates the bundles which Launch Services consults when searching for UTI declarations: app bundles, Spotlight importers, and Automator actions. http://developer.apple.com/mac/library/documentation/FileManagement/Conceptual/understanding_utis/understand_utis_declare/understand_utis_declare.html#//apple_ref/doc/uid/TP40001319-CH204-SW1 Ah well that's OK, this clears it all up for me. And yes, I did mean setting the UTI keys on the plugin rather than the app. Toe may toe, tuh mah toe... :)___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Custom bundle icon
Just an aesthetic question. I've implemented an API for cocoa plugins in my app, and the plugins use a custom extension, ftplugin. These plugins show up as folders in the finder, even though I've set the app icon to an icns file. Is there something particular I have to do to have the plugin treated as a package with my custom icon showing?

If only I'd searched a little longer, but the lack of definitive keywords made it difficult... http://lists.apple.com/archives/cocoa-dev/2006/Mar/msg01533.html Now it shows up and acts as a plugin in the Finder, but it still does not use the custom icon file that I've set.

Re: Problem running CocoaDVDPlayer sample
Didn't there used to be a technote on how to circumvent this behavior? iTunes pulls some of the same trickery. I doubt Apple would build in a way to circumvent this behavior. That would defeat the purpose of having it there in the first place. That said, you can build a kernel extension that circumvents this; it basically just hijacks the ptrace call for PT_DENY_ATTACH and immediately returns. I use something similar myself.___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: NSButton with image
If all I want is an image that acts like a button, do I need to subclass NSButton? I just want my button to show only my image and no Apple style button backgrounds. All this is easily found in the NSButton and NSButtonCell documentation. I believe what you are looking for is setImagePosition:NSImageOnly, setBordered:NO, setButtonType:NSMomentaryChangeButton. In InterfaceBuilder, all these options are available too. Image position will be the button showing just the square, the bordered option is a checkbox, etc.___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Spotlight-Style search menu
So I know how to set a view in an NSMenuItem, but my question is how to get it to look similar to the Spotlight search menu. For example, if I set the first item in a popup menu to a custom view, there is still a thin strip of white across the top. I want the gradient from the view to fill up the entire background. Is this a custom control or is there a way to get an NSMenu to behave like this?

Re: The Unadopted Protocol
This compiles and runs fine, even though MyClass never adopted the protocol Unadopted. It take it that by casting mc to an id, I cause the compiler to grasp at the only signature for testing that it knows about, namely the one in the protocol. So it happily uses that signature without complaint, and at runtime the correct message is sent to the MyClass instance. I noticed this, but I assume that by casting it to an id you are discarding the protocol conformance. I'd always thought protocol conformance was just to have the compiler warn you if you hadn't implemented a particular method. Doesn't it only get checked at runtime if conformsToProtocol: is called on it? By having an id variable, the compiler thinks it can accept any message, and if the object can respond to that message at runtime, it's all fine. So... maybe (d) :) ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Spotlight-Style search menu
Currently there is not. You should file an enhancement request at http://bugreport.apple.com asking for this feature. You're certainly not the only one who would like it. :) --Kyle Sluder Hmm that is slightly disappointing. Another couple of subclasses and dozens of lines of code for this one feature... I filed the enhancement request as per your suggestion, thanks for your quick response. I don't know but if you can set your NSStatusItem as a custom view and determine it's location on the screen, you can then show your custom view in a borderless window at that position This is the solution I've decided on as well. It's actually a button on a window that I want to trigger the search field to pop down, and I still want it to behave like a menu, i.e. clicking anywhere else on the screen dismisses the menu, and the button get's the pushed in look. What's the best way to achieve this behavior? ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Spotlight-Style search menu (SOLVED)
Well, you can have the custom view in the status bar to be a NSButton, it's action will compute the location and make the window key and visible at that location and when the window resigns key, just fade it away Brilliant!
