Re: Another app's UTI can break your app
On Jun 10, 2014, at 3:21 PM, Seth Willits sli...@araelium.com wrote: My app and Coda both open plain text .sql files. Coda exports a UTI for the .sql extension. So does my app. If .sql files are a public format that was defined by neither your app nor Coda, you should both be *importing* UTIs for it, instead of *exporting* them. I wonder if this problem would occur if both of your apps only declared the .sql type as imported? Exporting a type means you have defined that type and you control it. Importing a type simply means you would like to use it. Does it fix your app if you change your declaration to an import? Regardless, an incorrect export declaration shouldn’t break other apps that happen to use that UTI. It’s interesting that the documentation says what happens when you have multiple importers and one exporter (the typical case) but not what happens when there are multiple exporters (the error case).

Re: Strange toolbar/view/resize cursor interaction
I have an NSOpenGL view in a window with a nib-based toolbar that behaves correctly, so I don't think the OpenGL machinery is completely ignorant of toolbars. Noah Desch That sounds correct, but IIRC the methods that convert between a window’s content size and its frame size don’t take the toolbar into account, which means that they work with a content size” that isn’t actually the content *view* size, and correcting the calculation requires the assumption of extrinsic information. It strikes me as plausible that an OpenGL view might need to make such a conversion, and that it was never implemented to deal with the presence of a toolbar. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

[ANN] WFBezierCombinatorics
I’ve written a category on NSBezierPath that allows boolean operations on paths (union, intersection, subtraction) which preserves curved elements throughout the operation and does not require flattening paths into line segments prior to processing.

Re: [ANN] WFBezierCombinatorics
Graham, I’d be glad to see how it performs with your additional test cases. Although I spent quite a bit of time handling special cases this is very much a work in progress and I appreciate any help anyone is willing to throw in. I didn’t follow a specific algorithm, although much of the cubic bezier curve handling (bounding box computation, line-curve curve-curve intersections, curve derivatives, etc) is based on the descriptions here: http://pomax.github.io/bezierinfo/ In a nutshell, the algorithm I’m using is: 1) Walk the two input paths and add all their points to a vertex array 2) Compute intersections between the two paths and add them to the vertex array 3) Create two sorted index arrays which allow traversal of the polygons in order, including the intersections 4) filter out redundant intersections due to numeric imprecision and edge cases 5) Walk the sorted index arrays in order, building up the result bezierpath as you go, switching between the two index paths when you hit an intersection 6) Once you complete a polygon, pick the next starting point using some criteria determined by which operation (union,intersection,subtraction) you are doing. Some notes… Finding intersections between the two paths uses the naive n^2 algorithm. I’m aware there are better ones but the descriptions I could find mention only line segments and I am not sure how they generalize to curves. Finding zeros of a cubic curve (used for curve-line intersections among other things) is currently quite inefficient and involves 100’s of iterations of Newton-Raphson. I recently came across a more efficient method that I will implement shortly. Some of the unit tests in the project are not complete. I have verified their operation by examining the results in the debugger but writing assertions for dozens of vertices is quite tedious and I’m not done with that yet. -Noah On Mar 7, 2014, at 10:43 PM, Graham Cox graham@bigpond.com wrote: Hi Noah, Indeed, this is a potentially a very useful body of code.

Re: Core Data with ODBC databases?
I'm not sure why you need access to the NSSaveChangesRequest transactions at the application layer? In your optimistic locking example, your NSIncrementalStore gets a save request at step 5. It tries to commit the changes to the server, but the server comes back and says transaction back out. Your incremental store constructs an NSError describing the problem and returns nil from -executeRequest:withContext:error:. Your controller code that called -save sees the error, recognizes what it means, and starts the user back at step 1 (presumably by calling refreshObject:mergeChanges: on all the edited objects). Maybe I'm being naive but this seems to complete your scenario. Where did I go wrong? -Noah On Oct 18, 2013, at 9:12 AM, Mikael Hakman mhak...@dkab.net wrote: Both of you, Jens and Chris, are right. Core Data uses transactions internally for each NSFetchRequest and NSSaveChanges request. However, the transactions are not available in the user application. Let's consider the above mentioned banking application - a clerk making a withdrawal or deposit on an account. If your database uses optimistic transaction control then it will do the following: 1. Start a transaction. 2. Fetch account balance from the database. 3. Display balance to the clerk. 4. Let the clerk add or subtract an amount. 5. Update balance in database. 6. Commit transaction. 7. Check transaction error code. 8. if error code is Transaction back out or alike then the application should: 9. Inform the clerk. 10.

Re: UIPageViewController page index woes
So apparently the page control is entirely transparent by default. Try adding
this to your app delegate's didFinishLaunching... method:
UIPageControl * pageControl = [UIPageControl appearance];
pageControl.pageIndicatorTintColor = [UIColor lightGrayColor];
pageControl.currentPageIndicatorTintColor = [UIColor darkGrayColor];
pageControl.backgroundColor = [UIColor clearColor];
This will apply a default customization to every page control in your app. The
other way to apply non-transparent colors is to loop through all the sub-views
of your UIPageViewController's view and look for the one who's kindOfClass is
[UIPageControl class] and set whatever colors you want on it. This *might* be a
gray area in terms of using undocumented API though.

NSURLEffectiveIconKey with bookmark data
My application displays a potentially long list of items in an NSTableView. One
of the columns represents files on the user's hard drive. This column is driven
by the new bookmark data from the NSURL class. The bookmark data does not
appear to be able to save effective icon data, however other data does work.
Does anyone know of a way to get this to store the icon data?
Bookmark data for a given item is created as follows:
[[openPanel URL] bookmarkDataWithOptions:0
includingResourceValuesForKeys:
[NSArray
arrayWithObjects:NSURLEffectiveIconKey,NSURLLocalizedNameKey,Nil]
relativeToURL:Nil error:Nil]
According to the docs this should create bookmark data that also includes the
file's effective icon and localized name data so that I can access those two
items without resolving the bookmarks. I would like to avoid resolving every
bookmark in the table when they are displayed for performance reasons and
because I don't want the user to be presented with bookmark resolution dialogs
as they scroll through the list.
In my NSCell subclass I load the bookmark data as follows:
resources = [NSURL resourceValuesForKeys:[NSArray
arrayWithObjects:NSURLEffectiveIconKey, NSURLLocalizedNameKey, Nil]
fromBookmarkData:obj];
if ( resources ) {
[self setFileIcon:[resources
objectForKey:NSURLEffectiveIconKey]];
[self setFileName:[resources
objectForKey:NSURLLocalizedNameKey]];
return;
}
The result is that the name is displayed but the file icon is Nil. Stepping
through the code shows that the resources dictionary only contains one entry
(the localized name) instead of the expected two entries so the icon data is
not being stored or retrieved. As far as I can see this behavior (inability to
store icon data with the bookmark) is not documented anywhere.

as:
@interface MyClass

and you use the above line of code, and subsequently release myFields in your
