Question

I used this simple tutorial to create my singleton class. Everything works fine. One thing it doesn’t say in the tutorial, how to create methods in that class, so I can access them from other classes (e.g. other ViewControllers or the AppDelegate.)

How can I do it?
Thanks a lot in advance!

Answer 1

You will define methods just like you do in any other Objective-C file. Add a definition to the header for public methods and then implement them in the implementation (.m) file.

#import <foundation/Foundation.h>

@interface MyManager : NSObject {
    NSString *someProperty;
}

@property (nonatomic, retain) NSString *someProperty;

+ (id)sharedManager;

//Add instance methods for your singleton here
- (void)someSingletonMethod;

@end

Usage:

[[MyManager sharedManager] someSingletonMethod];
