Simply declare your class in your header file like so:

@interface MyClass : NSObject

+ (RecordingsMgr*)instance;


Then in your .m file, declare the instance function like so:

@implementation MyClass

+ (MyClass*)instance {
    static MyClass* _myClassInstance = nil;
    if (!_myClassInstance) {
        _myClassInstance = [[MyClass alloc] init];
    return _myClassInstance;


Then, whenever you need the instance somewhere, get it like so:

[[MyClass instance] someInstanceMethod]

If you’re concerned about thread safety, you can use this technique:
