RE:Instantly delete a directory without recursion?
Is there a way to delete a directory instantly and completely without first deleting all its subdirectories and files recursively? The hierarchical structure that you see is not real -- directories are not physical containers for the files that they appear to contain. The directory hierarchy is a carefully maintained fiction. Irrelevant aside: The original Mac file system took this a step further -- it made the directory structure totally a visual fiction -- all of the files were at the root of the (3.5) floppy) disk, and only _seemed_ to be arranged in folders. Thankfully this was supplanted by HFS. It is better to think of directories/folders as a special kind of file that contains an index to a set of files that it is going to _pretend_ to contain. Conceptually, this works much like classical Cocoa memory management. Each (directory/object) owns a set of (files/objects) by reference (retains the (file/object)). When you delete a file from a directory, it is released. If no other directory has an ownership claim on that file, it is dealloc'ed. Your (folder/object) doesn't contain the objects that it owns. It doesn't really even own them -- it just has a ownership claim on them. From Wikipedia's article about Hard Links: a hard link is a directory entry that associates a name with a file on a file system. A directory is itself a special kind of file that contains a list of such entries. Note that due to the use of hard links it is possible to have a single physical file that can appear in multiple directories. Each one of those directories owns a reference to the real file. Each reference is as real as any other. All references have to be unlinked for the file to be marked as deleted. The file can even have different names in the different directories! Hard links are the chain saw of filesystem features -- powerful, but potentially quite dangerous. Note that the OSX GUI provides no means of producing hard links, or even symlinks. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Why isn't this delegate protocol being seen?
Why not just include all of CoreLocation and have you added CoreLocation to
your framework list in Xcode.

While #importing CLLocationMangaerDelegate.h will work, you're probably best off replacing your individual header file imports with an import of the umbrella header CoreLocation.h. Also, a style point: when including framework headers, convention is to use angle brackets, as you have done for your UIKit.h import. It visually separates system headers from header files in your own project. --Kyle Sluder ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Instantly delete a directory without recursion?
When removing directories, the OS should remove all the tree created in the filesystem. I think you cannot do anything else? Is it so critical? How many files do you have to delete?

Re: Instantly delete a directory without recursion?
Hi Guillem, You are correct, in many cases the number of files will not be big, so it should not matter too much, but using the opportunity, I decided to illuminate myself regarding the possibilities there are in the file system. I had an idea that because the directory tree is growing from a single root, there *might* be a possibility to axe it off with a single hit. Is it possible? Thanks.

G S wrote: No it's not. CLLocationManagerDelegate is defined in CLLocationManagerDelegate.h. CLLocationManager.h only includes a forward reference to the protocol. Aha, right-O. Thanks. I had just done a quick search and found the string in there, and left it at that. I have a bunch of examples that for some reason import the specific files instead of CoreLocation.h. Replacing them with that single file did the trick. I do prefer the angle brackets, but have encountered unpredictable results when using them in the past. They do work here, however. Kyle was not quite accurate in simply referring to the brackets vs. quotes as a matter of style. An include directive with quotes searches in more locations than one using brackets. The oversimplified delineation is that the brackets will only consider system-provided headers while the quotes will consider those *after* first looking within your project. For a more correct explanation, I'd point you toward any C language reference. But as a practical matter the summary'll do fine until you get a chance.

How to get selected text in a WebView
I have a Webview, and I want to do something with the selected text. I tried: DOMRange *dr = [ webView selectedDOMRange ]; NSString *m = [ dr markupString ]; this contains the selected characters, but buried in lots of markup language. But I just want the characters. NSString *s= [ dr stringRepresentation ]; just returns Undefined. I could do [webView copy:nil ]; and then get the string from the general pasteboard, but I rather do not like to mess up the pasteboard - the user might have put something important there. So I tried: NSPasteboard *pasteboard = [ NSPasteboard pasteboardWithUniqueName ]; NSArray *types = [ NSArray arrayWithObject: NSPasteboardTypeString ]; [ webView writeSelectionWithPasteboardTypes: types toPasteboard: pasteboard ]; NSString *po = [ pasteboard stringForType: NSPasteboardTypeString ]; NSLog(@%s selectedString \%...@\,__FUNCTION__,po); but the result is: selectedString (null) Adding [ pasteboard declareTypes: types owner: nil ] does not make any changes. So what am I doing wrong? How to get the selection as string form a WebView?

Re: Instantly delete a directory without recursion?
No; the OS doesn't support this. From the lowest levels I can think of... One the posix side, you call rmdir() and that only works if the directory is empty (witht the exception of '.' and '..'). On the Carbon FileManager side, you call FSDeleteObject() and again, that only works if the directory is empty.

Re: Instantly delete a directory without recursion?
If you unlinked just the top-level directory node, you would leave all of its descendents with a link count 0, and the corresponding blocks claimed by the descendents would never be freed. (Ever. No one would have a reference to them, and they'd never be found in subsequent traversals.) To regain the space, you have to traverse through the structure and decrement the link count of the children of the tree. So, no. -- m On 04 Oct, 2010, at 01:24, Oleg Krupnov wrote: Hi Guillem, You are correct, in many cases the number of files will not be big, so it should not matter too much, but using the opportunity, I decided to illuminate myself regarding the possibilities there are in the file system.

It has to be strings because that's the definition of a property list and that method writes a property list representation.

Images / ImageRep
Hi,
I'm trying to add a feature to my application, where it collects all
of the images related to an entity, and puts them into an image in a
grid, so I'm planning on looping through the images, scaling them down
then placing them onto a new(blank) image, changing the placement
point each time.
I'm struggling with the whole image section, I think I can just use
NSImage, but I think I need NSImageRep for some things, one of which
being getting the original size to calulate the rescaled size. From
what I can tell I can't just tell it to resize to 100 pixels high, I
have to calculate what the width would be and set that at the same
time (I know I've also got to bear in mind it's points not pixels).
Is there a good tutorial anywhere for this? It doesn't seem too
complicated to me, if I can just get stated. So far I can't get the
size from an NSImage, and I can't get it to set the NSImageRep. My
images are stored as filepaths in the data, so the array I'll be
looping though will contain strings for the filepath for each image.
Code I'm working with:
- (IBAction)generateKitImages:(id)sender;
{
NSObject *kit;
kit = [[kits selectedObjects] objectAtIndex:0];
NSString* fileName = [kit valueForKey:@kitName];
//create new image 300px square
NSImage *image;
NSSize size = NSMakeSize (300, 300);
image = [[NSImage alloc] initWithSize:size];
//select all images for kit
NSArray* kitImages = [kit
valueForKeyPath:@kitItems.kitItemProduct.productImage];
//set coordinates to x,y - 0,100
//for each image
NSEnumerator *imageLoop = [kitImages objectEnumerator];
NSString *imgPath;
while ((imgPath = [imageLoop nextObject])) {
NSImage *img = [[NSImage alloc]initWithContentsOfFile:imgPath];
//resize to 100px high
//get original size
//calculate scale factor
//[img setScalesWhenResized: YES];
//[img setSize: NSMakeSize (100., 100.)];
//get new coordinates
//if coordinates are too wide, start new row - if x300, reset x to
0 and add 100 to y
//apply image to view
//get image width and add to coordinates
//set new coordinates
}
//apply kit logo to view
//apply kit date (text) to view
//save files out

[iPhone] Changing iPhone Application Language Programatically.
Hi, I would like to know whether its possible to change to a language other than provided list of languages in iPhone Settings. By default using localized .lproj folders .strings files we could make applicaton localized into selected language. For example, Languages like Sinhala are not in those set of languages in Settings. And there also does not have Sinhala Keyboard on iPhone. But Sinhala unicode font is available from iOS 4 onwards which is nice even it has some rendering issues. If I want to build a localized app for that language, is it legal and whether its possible that I will create si.lproj directory and programatically forcing the app to use strings in that folder ??

Interacting Sizes of NSScrollView and its NSClipView and a Custom NSView
I have a question based on my confusion over the interacting behaviors of an NSScrollView, its NSClipView and a custom NSView being displayed and clipped. I have an NSScrollView which resizes as its window resizes. Therefore the NSClipView resizes within the NSScrollView as the the window resizes. The custom NSView being displayed is small enough in size so that by enlarging the window far enough the NSClipView can become larger than the custom NSView. At this point the custom NSView becomes locked to the lower left corner of the NSScrollView and extra space is added to the top and right margins outside the bounds of the custom NSView. I would like the custom NSView to float in the middle of the NSScrollView under these conditions. Other applications seem to implement this behavior. I've been experimenting with settings but haven't been able to figure out how to get what I want. For the time being I have added the window delegate method windowWillResize:toSize: to force the window to stop growing at the point where the NSClipView reaches the same size as the custom NSView, so at least things look nice and neat, with the scroll bars going inactive at the exact point where the window stops growing, but I'd rather have the floating behavior. Can anyone offer any advice? Tom Wetmore, Massachusetts___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Hitting Layers
I solved the problem by examining checking to see if the game was in
fullscreen mode, and then changing how the NSPoint was calculated. It turns
out that everything was slightly offset in fullscreen mode when using
convertScreetToBase:. Not exactly a solution with an explanation; but at
least it is a solution (code below).
CGPoint point;
if (GameData sharedGameData] gameController] contentView]
isInFullScreenMode])
{
point = NSPointToCGPoint(mouseloc);
}
else {
NSPoint translated = [[gameController window] convertScreenToBase:mouseloc];
point = NSPointToCGPoint(translated);
}
CALayer *rootLayer = [[[gameController window] contentView] layer];
id hitLayer = [rootLayer hitTest:point];
if (![hitLayer isKindOfClass:[GameObjectLayer class]])
return nil;
else
return hitLayer;

I'm wondering that too. CALayer's hitTest requires a point in *superlayer*

you're obtaining mouseloc (your original point) that masks the issue when
you're not in fullscreen mode. m.

This means that all the standard rules for loading objects (ie don't touch relationships in awakeFromFetch) apply, and any business logic your classes implement on save will be triggered (unlike migration, which modifies the model to use NSManagedObject instead of custom classes). +Melissa ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: allKeys and allValues
Or do something like: NSArray * allKeys = [dictionary allKeys]; NSArray * allValues = [dictionary objectsForKeys:allKeys notFoundMarker:[NSNull null]]; This also guarantees a 1-to-1 correspondance.

Re: allKeys and allValues
Ok, I will not rely on that.
Anyway, I have seen that iTunes uses the same dictionary structure.
The file iTunes Music Library.xml contains a dictionary called Tracks.
This dict contains a series of dictionaries with an ID as key. So it's very
easy to get a track's dict asking for e.g.
[tracks objectForKey:@2604];
Instead using an array of dicts, in case I have to search for an item by its
ID, I must iterate through the whole array looking for that ID, e.g.
for(id item in items){
NSString *ID = [item objectForKey:@ID];
if([ID isEqualToString:@inID])
return item;
}

Re: How to get selected text in a WebView

Re: How to get selected text in a WebView
Was there a problem with what dr.text or [dr toString] returned after your first line? On 10/04/2010 12:15 AM, Gerriet M.

So what am I doing wrong? How to get the selection as string form a WebView?
