janodev / MySingleton.h

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")));
