The joy of unexpected SIGABRTs
I'm trying to get a rather important demo together and plan on being up all night again, so pleas pardon me if my brain power appears lacking. About 10 mins ago, before I started wiring up my GUI by simply dragging storyboard items into the .h file to make IBOutlets my app ran and displayed fine. I just spent 10 mins wiring up the GUI, did nothing else, and now when one scene appears, Xcode instantly SIGABRTs, without any information in the console or the debugger that comes close to telling why this happened. Nothing. This is what drives me insane about Xcode. So, I commented out all the code I just added and still, BLAM, directly when the scene loads. Even the breakpoint for the Init method isn't getting triggered. So, obviously, this is a storyboard issue, but which, but what? Considering that Xcode displays nothing at all that actually indicates what caused the SIGABRT, if it is thrown from a storyboard, what tips do you have to help track these unpleantries down when they are triggered form the storyboard? Trapping for -[NSObject(NSObject) doesNotRecognizeSelector:] doesn't help.

Sorry about the delayed response. I have been buried in work. I switched to
10.8 Mountain Lion and I am still adjusting to the revised Mail applicaiton.
You could do swizzling like this.
#import "JRSwizzle.h"
@implementation NSManagedObject (MySpecialCategory)
// Do the swizzling
+ (void)load
{
@autoreleasepool // NSAssert requires an autorelease pool
{
NSError *error = nil;
[[NSObject class] jr_swizzleMethod:@selector(method)
withMethod:@selector(my_swizzled_method)
error:&error];
NSAssert(error == nil, @"%@", error);
}
}
// Framework method
// - (void)method
// {
// ...
// }
// Swizzled method
- (void)my_swizzled_method
{
// do your thing
// call original implementation
[self my_swizzled_method];
}
@end
Note that the NSManagedObject documentation indicates "As with any class, you
are strongly discouraged from overriding the key-value observing methods". I
view swizzling like this: You are at your wits end, you have examined all other
options, you want to use Apple's frameworks but you simply can figure out any
other way. So you try swizzling.

You can place your NSFormatters are the top-level of your nib and connect your textfield's 'formatter' outlet to them, and also create outlets in your window/view controller to the same formatters. formatters are mutable, so you can configure them how you want in windowWillLoad or awakeFromNib or whereever.

Shared NSNumberFormatters
Hi Friends, I have an application that is currency using multiple NSNumberFormatters. Now a requirement has come up to support a per-document currency code. I have about 10 NIB files and the most complex NIB files have about 10-15 fields using per-NIB file formatters connected to fields using outlets. I would ideally like to use a binding on the text fields, e.g. bind formatter to File's Owner document.currencyNumberFormatter but unfortunately this binding isn't exposed in Xcode, which is leading to quite a bit of additional code to manually create this binding. Is there some way of achieving this more elegantly and efficiently?

Hmmm, the example output on that page looks all too familiar. I'll try

Sounds suspiciously similar to the NSArrayController bug where it
doesn't honor the NSKeyValueObservingOption{Old|New} KVO options.
There are quite a few references to this around the web, e.g.:

I think you're spot on with that one. I didn't realize that until after I sent
this email last night, however I'm still not sure how to solve the issue
(a.k.a. determine the correct key path). Here's an example of my data structure:
(
{
"name":"Boys",
"child": (
{
"name":Bill",
"child": ()
},
{
"name":"Steve",
"child":()
}
)
},
{
"name":"Girls",
"child": (
{
"name":"Anna",
"child":()
},
{
"name":"Bella",
"child":()
}
)
}
)
In my outline view, "Girls" and "Boys" are group headings and are immutable.
However, I want the names, "Anna", "Belle", "Bill" and "Steve" to be mutable
(which they are), but *those* are the properties I need to observe. Given that
this structure is in an NSTreeController, what is the proper keypath for
something like this? I'm pretty sure I just don't know the syntax, because it
seems like it should be something like
"content.chi...@distinctunionofarrays.name", but when I do that I'm pretty sure
I can hear the notification center giggling at me somewhere off in the distance.

Spotlight and Quick Look plugin behaviour change on OS X 10.8
My app uses a bundled Spotlight importer plugin and a Quick Look plugin. Pre 10.8 when the app is installed the 2 plugins are active immediately after application installation. I rely on Spotlight to index data files that I export from the app bundle into ~/Documents When my app is first installed I kick off @"/usr/bin/mdimport" and Spotlight duly indexes my content. Under OS X 10.8 behaviour seems to have changed. Neither of the plugins seem to be recognised by the OS until after a reboot. This interferes with my initial Spotlight indexing (the plugin isn't active so I get no results back). Has any one else noticed something similar?
