Re: getting last accessed date
Sorry about that no I'm on Mac OS I was just sending the email from my iPhone

Ok I double-checked and I think I am getting the same results as you are. But
iconForFile does not modify the Last Opened date that shows in Finder. So the
question is how do I get that besides using the spotlight metadata?

Why won't iOS app using MKMapView compile?
Hi all.
I put an MKMapView in my UI and tried to declare an IBOutlet for it,
but compilation fails with this error, in MKGeometry.h:
"'isinf' was not declared in this scope"
The line it's griping about is
UIKIT_STATIC_INLINE BOOL MKMapRectIsNull(MKMapRect rect) {
return isinf(rect.origin.x) || isinf(rect.origin.y);
}
I've imported where I declare the MKMapView, and
included MapKit.framework in the project.
Anybody know what could be wrong? Thanks!

The man page for "isinf" says you will need to #include and link with
-lm.

Can we get command line arguments in applicationShouldHandleReopen?
I have written an .app which is launched many times until the running instance shuts down finally. The code to start it looks like this: NSTask* task = [[NSTask alloc] init]; [task setLaunchPath: @"/usr/bin/open"]; NSString* app = [NSString stringWithFormat:@"%s", launchApp]; // launchApp is the app name NSArray* arguments = [NSArray arrayWithObjects: app, nil]; NSLog(@"==%@", arguments); [task setArguments: arguments]; [task launch]; ... Like regular GUI applications, a new instance of my application does not come up when above code Is executed. The application delegate has implemented applicationShouldHandleRepoen:hasVisibleWindows: This method returns 'NO' in the end. I want to access the command line arguments passed to the application in this method implementation. Is it possible? If yes, could someone point me to the relevant API please? I tried NSProcessInfo but it (correctly) gives me the arguments passed to the running instance. The idea is to launch the application with different arguments so that it can do different stuff every time. This design is inspired as a result of porting this code from other platforms, so I would be willing to look at other design alternatives if it does not work well in the Mac world. However I would like to give existing solution a try before I do that.

If the application is always running it cannot be relaunched with new command line parameters. Also command line parameters are seldom the right way to do something on Mac OS X with bundled applications (.app). You likely want to look at using AppleEvents and/or URL handlers for this... or maybe more advanced launch agent / launch daemon with IPC. -Shawn ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

To not copy the keys (i.e. work as I, at least, would expect), you must use the CFDictionary functions to add items.

Custom Colors as UITableViewCell background colors
Hello all, We’re creating a custom UIColor pattern (using +[UIColor colorWithPatternImage:]) and setting it as the background color of our table view cell. This works great—and avoids several headaches with rounded corners and grouped table views—except for one thing: when dragging a cell from one row to another, there’s a momentary flash on the selected cell and its neighbors. The flash appears to be whatever color is at the bottom-left of the cell, so probably at point (0,0) in the graphics context. Is there a method we can override to prevent this from occurring, or a better way to set a custom background color/image for a cell and keep its rounded corners in grouped style table views?

Re: Core Data Predicate Question
Well, when I said ANY, I really meant "IN termsArray", but for the
partial matches that you want your approach is fine, you'll just want
to use > & <= with character evaluations to speed this up. Check the
2010 CoreData Performance session from WWDC for more details, but it's
a standard SQL trick to speed up string comparisons.

I have used MKMapView just as you described: add the framework, import the header, go. It works. It seems likely that there is something amiss in your situation. This doesn't mean it's YOUR fault, merely that it's probably NOT the framework's fault. I guess I'd start by trying the following: 1) If you haven't already done so, do a clean build (including dumping any precompiled headers). I don't know why, but I've seen this fix all sorts of strange problems. 2) If that doesn't work, try building a MapKit sample code project. 3) If #2 succeeds, then it must be your code (or, less likely, something in your build settings) and we would need to see more to understand. 4) If #2 fails, your development environment is probably damaged in some way and you might need to do an Xcode reinstall.

Well, CoreFoundation.h includes according to my copy of the 4.2 SDK, and isinf is defined in both the simulator's and the device's math.h. CoreFoundation.h is #imported by Foundation.h.

Re: Why won't iOS app using MKMapView compile?
First of all, thanks a lot for the responses. I have compiled a couple of examples, and they do build. That makes this all the more perplexing. The MapCallouts tutorial is one that I tried. In their file that uses MKMapView, these are the import statements: #import #import Now the import statements in my file that uses MKMapView: #import #import Yep, identical. Now let's take a look at the included frameworks: http://farm7.static.flickr.com/6136/5917058068_14504106f4_z.jpg I link in everything they do. I refer to math.h in one file in my project (which works, and is not included in the problematic file). If I comment out that inclusion, compilation still fails with the same complaint. I've tried removing and re-adding the frameworks to the project (most of us have probably seen this fix things before). I cleaned the project and restarted Xcode. Still no dice.

Look at $SDKROOT/usr/include/c++/4.2.1/cmath and you'll see that it #undefines isinf and declares std::isinf as a wrapper. So if you happen to #include before #importing , the compiler will dutifully complain. I don't know what the recommended solution would be here, since I don't work with C++. Possible solutions that come to mind are splitting your C++ code and Objective-C code into separate files, and only including the bare minimum of glue in an Objective-C++ file; or #importing after whatever it is that #includes , but before #importing ; or inserting a `using namespace std;` before #importing .

NSArrayController - how?
Here's what I have plist file -> NSMutableArray of NSDictionary instances NSDictionary instances all have the same keys, but different values (like a database record) each NSDictionary maps to another class, RBSStore, that has properties that map to the keys of the NSDictionary's, and that has 2 methods: -(id)initWithDictionary:(NSDictionary *)aDic; -(NSDictionary *)storeDictionary; so that I can go from NSDictionary<->RBSStore. I've got the UI laid out, including the NSTableView (for displaying the NSDictionarys in the NSMutableArray, NSTextFields for each individual column (so that when you select a row, that row's info shows up in the NSTextField's, and one NSSearchField (not implemented yet.) Mostly, this is all done via code. How can I transform this into a design that uses bindings and an NSArrayController to eliminate most of the tedious BS, and allow the table view, text fields, and so on to all be linked together so when you update a field, the appropriate row in the table view (and the corresponding NSMutableArray model) all stay in sync? Mostly, what I don't understand is: what part of the work does the NSArrayController perform? Am I going to need an NSObjectController also to manage the individual rows (which are NSDictionary instances) and their corresponding NSTextFields? The big problem is the docs just describe the programmatic interface to the CoreFoundation classes, but not how to use them in real-world situations, or how to use them within IB. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Why won't iOS app using MKMapView compile?
Thanks very much for that analysis, Kyle. This blows. All of our business logic is written in C++, which I'd think is a common scenario (the paucity of "business" logic in the app store notwithstanding). This problem is occurring in a UI controller that needs to show information from a C++ object. It's full of code to exchange information between the screen and object and validate it, so writing some hokey workaround using an intermediary is pretty unpalatable. Weird that explicitly importing right before the MapKit import doesn't work, though. I can't see where cmath is being included. Any suggestions on tracking that down?

Re: Why won't iOS app using MKMapView compile?
Good grief. Anyway, thanks for all the help and time it took. I really appreciate it! For now, my workaround was to paste #define isinf(x)\ (sizeof (x) == sizeof(float )?__inline_isinff((float)(x))\ :sizeof (x) == sizeof(double)?__inline_isinfd((double)(x))\ :__inline_isinf ((long double)(x))) right before the MapKit import. It compiles now. If my app gets rejected, I'll just have to point them to bug 9748279 (which I just filed on this issue).

That is, maybe just use dictionaries on the way in and out of the plist (until the day you decide to move away from a plist as your storage format). > I've got the UI laid out, including the NSTableView (for displaying the > NSDictionarys in the NSMutableArray, NSTextFields for each individual column > (so that when you select a row, that row's info shows up in the > NSTextField's, and one NSSearchField (not implemented yet.)

The cornerstone of bindings is Key-Value Observing which is built on Key-Value Coding. So, the to-many relationship property has to be KVO-compliant for changes to its content. Plus, each item in the relationship has to be KVO-compliant for changes to the properties that you will be binding to. To make a to-many relationship property KVO-compliant, you should implement the mutating indexed accessors and use those accessors when you need to add, remove, or replace elements of the relationship. http://developer.apple.com/library/ios/#documentation/cocoa/conceptual/KeyValueCoding/Articles/AccessorConventions.html You can use the -mutableArrayValueForKey: method to get an object that you can treat just like a mutable array but will go through the KVO-compliant methods for you, but that's just a convenience. Generally, it's plenty convenient to simply call your mutating accessors. After everything is KVO-compliant, you would create an NSArrayController and bind its contentArray binding to the object with the to-many relationship property and to that property. Then, bind each NSTableColumn's value binding to the array controller, with the key path going through "arrangedObjects" and then the property from the dictionary (or RBSStore) that you want that column to show. So, something like @"arrangedObjects.firstName" if the column is to show the firstName property of each element. > Mostly, what I don't understand is: what part of the work does the > NSArrayController perform? You can't do Key-Value Observing _through_ an NSArray or NSMutableArray. NSArrayController and its arrangedObjects property allow for that. It also tracks selection for you. Plus it can do a bunch of other stuff if you want it to, but that should be relatively clear from the API. > Am I going to need an NSObjectController also to manage the individual rows > (which are NSDictionary instances) and their corresponding NSTextFields?

Have you read the Cocoa Bindings Programming Topics? http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/CocoaBindings/CocoaBindings.html Also see mmalc's Cocoa Bindings Examples and Hints page: http://homepage.mac.com/mmalc/CocoaExamples/controllers.html Here's another tutorial: http://cocoadevcentral.com/articles/80.php To the extent that you're setting up bindings in code while these discuss setting things up in Interface Builder, it should be straightforward to just translate from the IB stuff directly to code. IB is just a visual shorthand for the same sort of thing you'd do in code.

Re: getting last accessed date
Ok I have double-checked and the icon isn't actually the issue since I call iconForFile: after using stat. With the original code I posted it just gives me today's date. I can go into Finder and as an example I found a file that has a Last Opened date of 2009 and when I run stat it gives me today's date. So it looks like stat is definitely not working... Is there not an older Carbon method that was used for this before? Is the only way by using spotlight metadata? On a related note...I just updated one of my drives to Lion GM and on that drive I had a hard time to find a file with a different Last Opened date vs. Last Modified. Makes me think the Last Opened date in Finder is coming from spotlight metadata could that be true? If so then it looks like using the spotlight metadata and just falling back on the modification date might be the right way to go anyways???

Re: Nib loading cycle
On July 7, Manfred Schwind wrote:"On OS X all objects of the nib including the file's owner get an awakeFromNib." I don't think I ever found the doc for that, either, but I did learn the hard way. I was instantiating a NIB multiple times with "InstantiateNibWithOwner:topLevelObjects", but I inadvertently used the same object which owned the nib when it was loaded. I ultimately found doc that said each instance had to have a unique owner, but no reason was given. My owning object got multiple "awakeFromNib" calls. Eventually, I pieced the two together.
