The sandboxing engineers have been fairly responsive on devforums.apple.com, but those responses have lately devolved to "file a Radar describing how sandboxing is interfering with your app." Of course they can't comment on the November 1st MAS sandboxing deadline; that's still a giant question mark. I'm under the inpression that the security folks developed app sandboxing in a relative vacuum and presented it to the App Store team who loved the benefits it brought. But then they announced it to the world and DTS informed them of how much of the Mac ecosystem it actually breaks. We really need Apple to either reiterate the deadline or announce its delay. That announcement won't happen on this list, and the best way to influence that decision is to give solid reasons to the sandboxing engineers via Radar (with bug numbers posted to the dev forums) and possibly a followup email to your friendly DTS representative. --Kyle Sluder ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Not sure why you're saying they are orthogonal. In order to sandbox an App you need to sign it. One thing's for sure, whenever security people get involved with something, stasis sets in.

Re: NSOutlineView drag and drop: how to prevent parent being dropped on one of its children
Thanks Kyle, I'll try to apply that. In the meantime, I also found the
AbstractView sample code which does something similar. I'll see which one fits
my code better.

If your outline view is set up such that children are descendant items
of their parents, you don't even need to round-trip to the model
layer. You could implement something like the following:
// Warning: typed in Mail, not guaranteed to work
- (NSDragOperation)outlineView:(NSOutlineView *)outlineView
validateDrop:(id < NSDraggingInfo >)info proposedItem:(id)item
proposedChildIndex:(NSInteger)index
{
NSArray *draggingItems = ItemsFromDragInfo(info);
NSMutableSet *parentTree = [[NSMutableSet alloc] init];
id parentItem = item;
while (parentItem) {
[parentTree addObject:item];
parentItem = [outlineView parentForItem:item];
}
NSDragOperation op = NSDragOperationMove;
for (id item in draggingItems) {
if ([parentTree containsobject:item]) {
op = NSDragOperationNone;
break;
}
}
[parentTree release];
return op;
}

NSMetadataQuery - Just a warning.
Hi, I just had a hard time with NSMetadataQuery and would like to share the results. NSMetadataQuery leaks one MDQuery for each change of the predicate. Even deallocation of a NSMetadataQuery does not free the MDQuery objects that have been created internally to run the query. Beyond the possibility of nasty crashes, this goes along with quite a strange side effect: You can place 128 searches within your app before NSMedataQuery class will end up in no longer search for anything. Even newly created instances of NSMedataQuery will not start searching for the first time after this weird barrier has been reached. You can simply reproduce this with Apple's spotlighter example. For time saving reason, I replaced spotlighter's editable text field by NSSearchField and toggled its cell to search immediately (-setSendsSearchStringImmediately: set to YES). Start to type in some search strings. After typing in 128 chars spotlighter will ignore further requests. System: 10.7.2 (Lion), have not tried with 10.6.x yet. A workaround is to call -stopQuery on NSMetadataQuery, before a new MDQuery will be created internally (change predicate, start searching) and in -dealloc of NSMetadataQuery to get rid of a possible running query that have not been explicitly stopped yet. I additionally placed a stop when NSMetadataQueryDidFinishGatheringNotification is received. Doing all this causes the underlying MDQuery to be freed when no longer needed and before a new search will begin. And this also magically removes the limit of 128 searches. I am wondering if calling -stopQuery so often has any negative effect on internal caching (AFAIK result items may be shared among queries). Yes, I will place a bug report asap.

NSOutlineView drag and drop: how to prevent parent being dropped on one of its children
Hi, I'm setting up drag and drop for my NSOutlineView and I want to prevent parents being dropped on one of their children. The parent and children are all of the Group entity. I understand I need to do this in the outlineView:validatedrop method. I think I need to create an NSFetchRequest with the NSPredictate to get all the children of the parent, but I don't know what the predicate should be. It should be recursively, so it should also get the children of children, if any. Any suggestions?

STL algorithms and NSEnumerator/NSFastEnumeration
I have this Objective-C container which I want to use in an algorithm that only takes STL iterators. Is there a generic adapter for NSEnumerator or id that will provide appropriate STL iterators? Also, is there a way to tell the difference between two NSEnumerators (a la STL iterator difference)? Is equality defined for NSEnumerators? Is it possible to clone an NSEnumerator? ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Future for Mac applications
This subject came up about a year ago when Lion was first announced here was the reaction to it: http://9to5mac.com/2010/04/25/jobs-mac-store-negative-ghostrider-593035053/ While Steve is now no longer with us.

Re: IKImageBrowserView spinning animation on the Cell
Create a CALayer with the spinning effects. and use the following IKImageBrowser cell Core Animation layer method. - (CALayer *)layerForType:(NSString *)type where NSString is a “Cell Layer Positions” type IKImageBrowserCellForegroundLayer. For the spinning effects layer have a look at https://github.com/kelan/yrk-spinning-progress-indicator-layer. You should be able to use the YPKSpinningProgressLayer classes for what you need.

IKImageBrowserView spinning animation on the Cell
Dear list, I have an IKImageBrowserView based app which retrieves thumbnails from web service, which is much like iPhoto app. I want to support progress indicator animation in the placeholder layer of the IKImageBrowserCell. Depends on the network speed, there will take a long time to download the thumbnails, so I want to add a spinning progress indicator on each cell to tell customers which thumbnail is being downloaded. After customer double click one cell, the original image file also will be retrieved from web service, there also has a requirement to draw a spinning progress indicator animation on the cell to tell the customer the wanted one is being downloaded. My question is how to add a spinning progress indicator animation on the placeholder layer? I have some basic knowledge using the core animation, but no idea to address this kind of issue. Can anyone give me any guidelines to push me on a right direction?
