AlanQuatermain / AQPerThreadManagedObjectContext.m
Created May 28, 2010 14:17
A set of simple wrapper functions to get per-thread NSManagedObjectContext instances. When creating main context (i.e. in app delegate) pass it to StoreManagedObjectContextForCurrentThread(). Then just call PerThreadManagedObjectContext() anywhere you nee
static NSString * const AQPerThreadManagedObjectContext = @"AQPerThreadManagedObjectContext";
void StoreManagedObjectContextForCurrentThread( NSManagedObjectContext * context )
{
[[[NSThread currentThread] threadDictionary] setObject: context forKey: AQPerThreadManagedObjectContext];
}
NSManagedObjectContext * PerThreadManagedObjectContext( void )
{
NSManagedObjectContext * result = [[[NSThread currentThread] threadDictionary] objectForKey: AQPerThreadManagedObjectContext];

AlanQuatermain / SingletonInitializer.m
Created November 2, 2010 14:45
An implementation of a Singleton accessor routine. Provides a dispatch_once-based version and a plain version for pre-(10.6|4.0) systems, with load-time method swapping to install the dispatch version if libdispatch is available at runtime.
#import <libkern/OSAtomic.h>
#import <dispatch/dispatch.h>
#import <objc/runtime.h>
@implementation MySingleton
+ (void) load
{
// check for weak-linked libdispatch symbols
if ( dispatch_queue_create != 0 )

AlanQuatermain / iOS_42_Simulator_prefix.pch
Created November 2, 2010 15:34
A fix for iOS 4.2 builds against the iOS Simulator: some APIs (look at AVFoundation) are marked as available for 10.7. Sadly the Simulator SDK version of Availability.h doesn't define the 10.7 macros, so it results in horrible compiler errors on all such
#import <Availability.h>
// Fix a bug in the current iOS 4.2 beta SDK where 10.7 version isn't defined
#ifndef __MAC_10_7
#define __MAC_10_7 1070
#if !defined(__MAC_OS_X_VERSION_MAX_ALLOWED) || (__MAC_OS_X_VERSION_MAX_ALLOWED == __MAC_10_6)
#ifdef __MAC_OS_X_VERSION_MAX_ALLOWED
#undef __MAC_OS_X_VERSION_MAX_ALLOWED

A tcpdump log of a print session from an iPad to the Print Simulator running on OS X 10.6.4. Search for UNIRAST to find the start of the image data. Warning— it's a long one.

An Xcode 3 script which will insert a New BSD License comment at the head of a file. Place the caret at the top of your file (or select an existing header comment) and run the script via the Xcode script menu. I have mine in the 'Comments' group, bound
