Enumerating folders/files in dmg without mounting it & selective file extraction
Hi, In my application, I am browsing to an user selected dmg file, mount it (using 'hdiutil attach') , validate it for required custom folder structure (enumerating the folder structure) & file data, unmount it (using 'hdiutil detach') and return the results back. The process takes a bit time to mount/unmount dmg files. I am looking to reduce the time required. Is there a way out to enumerate the dmg folder structure without mounting it & options to selectively extract a single file from dmg (something analogus to zip files)? will it improve the performance? Please suggest. Thanks, Sachin ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

how to redraw a view
Hi all! I have a view whose drawRect method draws a plot according to a few parameters which are global variables. When I change these variables according to the user input, I want to update that plot, so I need the drawRect method of my view to be called. I tried [self setNeedsDisplay] or [MyView setNeedsDisplay] but this doesn't work. So my question is, what is the correct way to ask my view to be redrawn?

Problem with plugin architecture development and subclass into bundles
Hello List, I need to make a plug-in based application. The most common way is to define a protocol that each plugin (bundle) principal class must follow. However for some reasons I need to use subclasses instead of protocol. So I've a PluginLoader class and a BasePluginClass. This class is the superclass of each plugin's principal class. It contains some methods and bla bla. This is my environment: http://i.imgur.com/PLJgm.png The main problem is at runtime when I get this error: Class MKAbstractUITool is implemented in both /Users/malcom/Desktop/MyApp/build/Debug/MyApp.app/Contents/MacOS/MyApp and /Users/malcom/Desktop/MyApp/build/Debug/MyApp.app/Contents/PlugIns/UITools/iOS/MKiOSTabBar.MyApptool/Contents/MacOS/MKiOSTabBar. One of the two will be used. Which one is undefined. This because I've imported my BasePluginClass (named MKAbstractUITool) both in main app and my plugin. That's not only a warning but a problem because when I try to load a (valid) plugin this check fail if ([prinClass isSubclassOfClass:[MKAbstractUITool class]] == NO) and return NO. (and my prinClass is a subclass of that). I've also tried to use @class MKAbstractUITool but it return error linking (cannot found MKAbstractUITool...). It's the same using HEADER_SEARCH_PATH instead of importing .h and .m of MKAbstractUITool into my bundle project. And it's the same importing only the .h. Any idea?

Re: unit test exit's abnormally with code 5
I had something similar the other day: the release configuration
worked but the debug configuration would get that same NSTask error
22.
I did a test app that would load the unit test bundle to get more
details on the failure. I got a "malformed rebase opcodes (331/664)"
error, which seems to come from the Mach-O image loader.
I ran out of time so on a hunch I switched the compiler from LLVM 1.6
to LLVM-GCC 4.2 and now it works fine, so you might want to give this
a try. My unit tests were working fine before I updated to the latest
iOS SDK so I'm guessing this is a new bug in LLVM.

Saving a file in a new folder
Hi, When the user does a "Save As", I want to create a folder with the same name as the file name they chose and put the file in that folder because there are other files associated with the main file being saved. I'm using [NSData writeToFile] to save and I thought about moving it after it is saved with [NSFileManager movePath] in my documents saveToURL method. Or calling [NSDocument setFileURL] in my documents writeToURL method, but I'm not sure it's OK to change the URL there.

I know I could cancel the current animation and start a new one using the current [layer presentationLayer]'s value as the fromValue, but this is not convenient because my animation is repetitive and after such a manipulation it will start from a wrong fromValue on the next loop.

Yep, NSCell certainly seems to introduce a whole bundle of corner cases – this is the second of any significance I've tried to implement, and each has thrown up different bizarre behaviours. Here's hoping that now that drawing efficiency is less of an issue, apple can refactor NSOutlineView and NSTableView into an NSOutlineView2 that uses something more akin to CocoaTouch's cells (that are still views) for drawing.

The best way to do this is to write your code (i.e. the controller and the model, not the view) to keep internal state.

Cells are mostly designed, as far as I can see, to relieve the view of a repetitive drawing task.

You could just pass everything to the cell, but then it wouldn't work the same in a standard control. There is no defined protocol beyond the usual control <--> cell methods which allow you to, e.g. start and stop editing, but do not go further down to individual key events, which are handled by the Field Editor. There are further interactions between the Field Editor and the cell though, maybe your cell could use the FE in a standard way for editing? I've made a few NSCell subclasses in my time, and every time it was a deal of trouble. In your case if you want to use NSOutlineView as a host you'll probably have to accept the hassle, or try to make your cell fit in a more standard way. Sorry the advice is rather vague - every case seems to be different. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Though in that case, you could just make a custom view. Unfortunately, I'm embedding these in an outline view, my current thinking is to subclass NSOutlineView and hack my own responder events to talk to my cell, but it seems a bit of a hack – it embeds part of the semantics of my cell in a class elsewhere, and stops the cell being composible in other scenarios.

A cell is usually a component of a view. The view is the responder, but I presume the -acceptsFirstResponder method in NSCell is really there so that the host view can defer to its cell to answer that question. If you want to use the cell in a standard view, such as a tableview , matrix, or other control, you'll have to figure out how those classes interact with their cells. If it's in a custom view of your own, you can probably be more loose with how you do it, if compatibility with standard controls isn't required. Though in that case, you could just make a custom view. --Graham ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Responding to the keyboard in an NSCell
I'm trying to implement an NSCell which should be able to respond to the user pressing backspace to delete something, but I don't quite see how keyboard handling is meant to work. The - (BOOL)acceptsFirstResponder method seems to suggest that NSCell *should* be an NSResponder subclass. It isn't though, and it doesn't get sent things like -keyDown: if you return YES from acceptsFirstResponder. I get the feeling that I'm missing something obvious here, but I could do with a prod in the right direction.
