Re: Core Data Fetches + Transient Properties + NSPredicateEditor = Sadness

If it helps, the reason for Apple only supporting searching of persistent properties is for performance. If you're using the SQLite store for example, the predicate is not evaluated against the in- memory objects, but against the individual bits of data in the SQLite table. Of course, why Ap

Advanced Core Data and Inverse Relationships Question

I have two entities Boss and Employee. Boss has the to-many relationship 'employees'. The inverse is, naturally, the to-one relationship 'boss'. My problem is this. I have a custom key that I implement for Boss. And while I am BETWEEN (i.e. the code between) willChangeValue:forKey: and didChan

Keeping IB class instance and xCode instance the same

I'm always anxious when I have to actually deal with IB... Sorry to say it, but it's true. It just makes very little sense to me... Anyway, I have a problem. I've got a class that's instantiated in IB, but I need to load it's state from a file. This file defines the class itself, so when I

Safe Signal Handling from the Run Loop

Hey list, Earlier today I spent awhile trying to re-find some sample code that I discovered awhile ago. I eventually found it, and thought I would mention it here in hopes that it'll help someone in the future. It allows you to handle signals safely within your app's runloop, rather than trying t

Bindings Update with Drag-and-Drop [solved]

I've managed to solve this problem. For those who might be looking at this problem sometime in the future, note that in the code below, there would be no need for -willChangeValueForKey: and - didChangeValueForKey: in any case, since -setValue:forKey: does that work anyway – -willChangeValu

Bindings Update with Drag-and-Drop

I have a number of NSTextFields that are happily bound to NSString objects in the controller, and they work very well: if the textfield is updated, the corresponding NSString object is updated, as vice- versa. Now, in order to implement drag-and-drop, I have had to subclass NSTextField and

Select Object in NSDictionaryController

I have a table with two columns, labeled "Key" and "Value" bound to myDictionaryController.key and myDictionaryController.value. Now I want to select a row programmatically (e.g. [ myDictionaryController selectRowWIthKey: @"someKey" ]; ). But such a method I cannot find. And trying to use t

Using CFStringTransform with Attributed strings or runs, maintaining the styling of the Attributes in transformed results.

Currently, I'm using CFStringTransform to convert Java-based strings files (JBoss .properties files) to something human-readable for verification. Works brilliantly. Luckily, these files are short and this function is super fast. This enables me to naively take all the text of a file provided

NSSavePanel and file formats

I notice that the current HIG recommends the use of a file format popup in the Save dialog, when an application supports multiple formats: http://developer.apple.com/documentation/UserExperience/Conceptual/AppleHIGuidelines/XHIGMenus/XHIGMenus.html#/ /apple_ref/doc/uid/TP3356-TPXREF105

Re: SQLite 3 crash report - debugging help needed

See TN2124: Mac OS X Debugging Magic ( http://developer.apple.com/technotes/tn2004/tn2124.html), specifically, the section titled "Architecture Considerations". You'll know what types to expect for each argument to the function by looking at the sqlite3 source code. —Jeremy On Sat, Apr 18, 2009 a

Re: SQLite 3 crash report - debugging help needed

How did you come by this crash log? From the 0x48, it looks like it's attempting to dereference an int passed into sqlite3VdbeExec where a pointer should go, but that's a wild guess. The crash log came from one of my testers. It's dying in sqlite3 code, so you have access to the source. Take
