[Objective-C] Simplify singleton implementation

Singleton

Simplify singleton implementation

How to use

1. Inherit from Singleton

// Foo.h

#import "Singleton.h"

@interface Foo : Singleton
@property (strong, nonatomic) NSString *title;
@property (strong, nonatomic) NSString *anyProperty;
@end

2. Override "sharedInstanceInitializer"

// Foo.m

#import "Foo.h"

@implementation Foo
- (void)sharedInstanceInitializer {
    _title = [self.class description];
    _anyProperty = nil;
}
@end

3. So easy

// main.m

Foo *foo = [Foo sharedInstance];
