How to restrict an app to run from harddisk
Hi,How can I check whether my application is running from Harddisk or from a removable media (CD, USB drive...). I used [[NSWorkspace sharedWorkspace] getFileSystemInfoForPath:path isRemovable:&isRem isWritable:&isWritable isUnmountable:&isUnmountable description:&description type:&type] method and used the "isRemovable" parameter to check whether it is removable media or not. It works fine if i directly copy my app to HDD, CD or USB drive. But if I create a disk image of my application and keep it on har disk and then I run my app from disk image the isRemovable parameter still shows that it is running from removable media and that's not true. My purpose is I dont want my user to run my application from Hard Disk. Please suggest some way to achieve this.Thanks & RegardsAbhijeetGet Yourself a cool, short @in.com Email ID now! ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Thank you, Quincey. Yes, I know about that – arghhh – IB limitation. That's why I -bind in the window controller's -awakeFromNib. > With a code-based approach, it may be easier and clearer just to implement > the two halves of the behavior directly: Yes, I see what you mean. This may be one of those cases where Cocoa Bindings makes life more difficult instead of easier. In this case, I kind of like the binding though, because all of the other fields in this Inspector window use bindings, and I'd rather not break the pattern. I'll read "How Do Bindings Work" and see if I can find any "technical violations". Jerry (For sake of list archives, for anyone else who wants to try this, there's an important detail I left out of my original post. Remember to -unbind: in the window controller's -windowWillClose or -dealloc, or you'll get exceptions and/or crashes. I do it in both methods, calling a method which also removes other observers. I use an instance variable, m_isObserving, to keep track of whether or not my bindings and observers are active.) ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Well, yes it is. The disk image is unmountable. Maybe the system's definition of removable is different than yours, but really how do you define this for virtual media. > My purpose is I dont want my user to run my application from Hard Disk. > Please suggest some way to achieve this. Inherently stupid, user-hostile, unenforceable requirement--give it up? Or accept the limitation that a disk image is always removable. Or go to extreme lengths to use lower-level calls to determine that the volume is a disk image, then find out where it's located, then check the containing disk type. -- Scott Ribe scott_r...@elevated-dev.com http://www.elevated-dev.com/ (303) 722-0567 voice ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

MapKit overlay tip
Just wanted to pass on this little pearl I just discovered in the case that it might help someone else. I've got a bunch of images that I'm using as mapKit mapView overlays for iOS devices and of course was interested in having them be as small as possible and load as fast as possible. So, I took all the PNGs and converted them to JPEGs at varying compression sizes and got them nice and small. Map drawing time went up terribly and the images and maps started slowly chunking in on the devices. Don't use JPEGs. Use PNGs. it's a world of difference in map drawing performance. Hope this tip/warning helps someone. Cheers, - Alex ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Note that as part of the build and bundling process, Xcode runs PNGs through pngcrush, which does a variety of optimizations that reduce file size and, I believe, do some hardware-specific decoding optimizations. The upshot of this is that a comparison of raw PNG and JPG files is totally meaningless; you would have to actually look at the post-pngcrush output, and even this wouldn't tell the whole story. If you are doing performance tuning, you should take a look at the pertinent documentation (e.g. https://developer.apple.com/library/ios/#documentation/iphone/conceptual/iphoneosprogrammingguide/PerformanceTuning/PerformanceTuning.html). There and in other docs Apple explicitly notes that PNG is "the preferred image format for iOS apps." (Something I hadn't really thought about is that this would suggest different performance for PNGs that are downloaded by an app versus those that are included at build-time. Does anyone know whether there is a noticeable difference?) -- Conrad Shultz Synthetiq Solutions www.synthetiqsolutions.com ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

NSTextView row number
Hello, I have a NSTextView and would like to keep track of where the cursor is in terms of a line number. Please, is there a way to figure this out somehow (akin ti lineRangeForRange:) or do I have to calculate it myself, e.g. by caching newlines locations? ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

PDFThumbnailView Problem (kind of)
Dear Cocoa-gurus, I have a typical thumbnailview on a drawer and a pdfview in main window. I have a category that lets me drag and drop a pdf onto the pdfview; it then gets the url and sets a pdfdocument to that url; sets the pdfview and sets the thumbnailview to the pdfview. It "seems" to work; but I can't click on the thumbnails; they're there, but not clickable, until I resize the window, then all is well. Any idea of what's going on and what I need to do to "liberate" my thumbnailview (I've tried sending a setNeedsDisplay:-- Nada).

group row custom drawing nstableview
Hi, I'm having some trouble doing a custom drawing for my group row in a view-based nstableview. First of all I subclassed NSTableRowView is this correct? And if so the problem I'm having is to recreate the floating effect which normally happens automatically if using a standard NSTableCellView. I'm able to get the isFloating property, but I'm not sure what's the correct way to make the row float (setAlpha?) without making the text "float" as well? Any pointers to get me going in the right direction here would be much appreciated.

I've had a similar issue (and there are other issues with PDFThumbnailView that
you may or may not run into). This is how I worked around it:
self.thumbnailView.PDFView = self.previewCanvas;
dispatch_async(dispatch_get_main_queue(), ^{
self.thumbnailView.thumbnailSize =
self.thumbnailView.thumbnailSize;
});
Simply setting the thumbnail size causes the thumbnail view to straighten
itself out.
