Dynamic get/set. Watch it, I'm using [[NSThread currentThread] threadDictionary] for thread-safe access.

	@autoreleasepool {

	NSUInteger (^factorial)(NSUInteger n);
	NSUInteger (^__block __weak weakFactorial)(NSUInteger n);

	return n==0 ? 1 : n * weakFactorial(n-1);

janodev / Person.h

Different ways to execute a block property. This runs in CodeRunner. Replace one of the #ifdef X below with #ifdef YES, and comment person = nil;.

	#import <Foundation/Foundation.h>
	#undef X

	typedef void (^salute_t)();

	@interface Person : NSObject

	@property (nonatomic,copy) NSString *name;
	@property (nonatomic,copy) salute_t salute;

Last active July 28, 2016 03:19

Singleton pattern with __atribute__ unavailable to prevent the accidental misuse of a singleton. Note that the user is still able to create more instances using runtime functions.

	#import <Foundation/Foundation.h>

	@interface MySingleton : NSObject

	+(instancetype) sharedInstance;

	// clue for improper use (produces compile time error)
	+(instancetype) alloc __attribute__((unavailable("alloc not available, call sharedInstance instead")));
	-(instancetype) init __attribute__((unavailable("init not available, call sharedInstance instead")));
	+(instancetype) new __attribute__((unavailable("new not available, call sharedInstance instead")));
