Mission Control Hiding Window
I have a window that is the size of the display and has a z-order to put it between the desktop picture and icons. I call: setCollectionBehavior:NSWindowCollectionBehaviorCanJoinAllSpaces | NSWindowCollectionBehaviorTransient | NSWindowCollectionBehaviorIgnoresCycle This lets it move betwen spaces, but when I go to Mission Control, it hides it completely. Using NSWindowCollectionBehaviorManaged doesn't work as the window gets too small and no longer covers the small desktop representations completely. Using NSWindowCollectionBehaviorStationary doesn't work as then you can't see anything in Mission Contral as it is covered up by my window. How can I make this work? This window needs to behave like a desktop picture. Note that I can't use a real desktop picture as there is no way to set them on a per-space basis.

spotlight importer extract file from zip archive
Hi, I am trying to create a spotlight importer, but my files that I want to index are zip files, and NSTask will not run from the mdimporter process, since it is not blocked by the sandbox. How can I get files from my zipped documents without having to run an NSTask?

I was going to recommend something similar. The inability to express mutation of a heavyweight model object is a serious shortcoming in KVC/KVO. Most of the time it works; objects generate the right change notifications and observers pick them up. But then some intermediate observer gets smart and says "aha, the old and new values are pointer-equal! I don't need to forward this change notification for my derived keys!" and the entire thing breaks down. I've filed bugs asking for richer self-description of key types (basically -isOrderedToManyRelationshipKey: and the like). Perhaps we should also have -isMutableObjectKey:. Either that or the framework should stop eliding forwarded change notifications just because the values don't compare pointer-equal. --Kyle Sluder ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

It sort of works for streams reading from a memory buffer, IIRC. By "sort of", I mean it sometimes returns data and sometimes silently discards data. I now avoid NSStream/CFStream unless I'm dealing with an API that requires them--- they seem to be an unmaintained corner of the codebase. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I don't know for sure, but I would bet it's streams reading from files, which have become memory mapped.

When does NSInputStream's -getBuffer:length: actually work?
NSInputStream has a -getBuffer:length: method that lets you get the available data from the stream without copying. This is great for performance, and I've written my client code to take advantage of it if it's supported, but every time I've tested, it isn't supported (i.e. just returns NO) so my code just falls back to calling -read:maxLength: instead.

RE: PDF Rendering on iPad's
Dave, > I have a few questions about rendering PDFs and wondered if > anyone here could help. In my open source iOS PDF viewer (https://github.com/vfr/Reader) I employ two techniques: 1) Show a low resolution image of the page below the CATiledLayer-based zoom-able page view. These low resolution page images are generated on a background thread and are also cached as PNGs for future use. This gives the user something to see while CATiledLayer draws in the details on top of it. 2) Reduce the number (and increase the size) of tiles that CATiledLayer asks to be drawn. I set the CATiledLayer's tile size to either 512 or 1024 pixels depending on the device's screen size and scale (CATiledLayer limits the tile size to 1024 pixels). If the screen scale is greater than 1.0, I set the levelsOfDetailBias to 1 (any higher and CATiledLayer asks for many, smaller tiles). I also return a small value for +fadeDuration (as returning 0.0 exposes a bug in CATiledLayer - sometimes a tile won't draw or flickers in and out until you touch the screen). All of this is done in a CATiledLayer subclass (https://github.com/vfr/Reader/blob/master/Sources/ReaderContentTile.m) which is used to back the PDF page content UIView. You should also be aware that there is a bug in iOS 5.1.x where CATiledLayer will ask for the same tile to be drawn 2 or 3 times. If there is anything else, let me know...jo ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

PDF Rendering on iPad's
Hi All, I have a few questions about rendering PDFs and wondered if anyone here could help. I've inherited some code that tiles the PDF, I think this code was based on one of the Apple Sample Apps from a while back. I'm rendering a PDF on an iPad, it's a magazine with lots of text and obviously we'd like to run as fast possible, one thing that gives an impression of "slowness" is the fact that it renders from bottom up, so my first question, is there anyway I can make to render top down? The idea is that when a user is presented with a page, that naturally start reading from the top down, and since it's just a blur when initially rendered it makes the experience less than pleasing. The next thing is that I remember seeing some an article with some sample code somewhere that altered the rendering parameters depending on the type of iPad being used, e.g. iPad1, 2 or 3 (it probably handling iPhone too, but I don't need to do that), but I can't for the life of me find the exact article I read. I have found some code on StackOverflow but doesn't seem complete. So if anyone could point me to a some sample code that optimizes for the type of device or documentation that explains what needs to be done, I'd be really grateful.

Re: -mouseDragged: sent to view when dragging window
On 7/24/12 11:29 PM, Quincey Morris wrote: My view reacts to -mouseDragged: but doesn't check if there's been a -mouseDown: first because that's implicit. Did that change? The Cocoa Event Handling Guide says "Mouse events are dispatched by an NSWindow object to the NSView object over which the event occurred", so I guess there's a lag/race condition that's putting your view under the mouse pointer at the moment the event is generated. It also states (a few times in different wording): For each dragging sequence, the Application Kit sends a mouseDown: message to a responder object, then sends one or more mouseDragged: messages, and ends the sequence with a mouseUp: message. < While it doesn't spell it out, it's pretty clear they're talking about the same view/responder for all those events. I think it's implicit that a mouseDown has occurred before a mouseDragged, but I don't see anything that guarantees they're sent to the same view. In that case, you should really set a state flag in mouseDown that's checked in mouseDragged. When I click into a view and drag, it gets all dragging events, even if the cursor is dragged outside its frame. Also, views over which the cursor is dragged during this process, don't get a single -mouseDragged: message. I don't believe that getting -mouseDragged: without a prior -mouseDown: or following -mouseUp: is intentional.
