Force deletion of singleton in test code that was created with dispatch_once

Question

I\'m writing some unit test code for a model class and want to simulate the behavior of the class during app exit and relaunch. I could achieve this by deleting and re-allocing

Answer 1

sure something like this would be fine for unit testing, you can turn it off for prod:

static MyModel *singleton = nil;

+ (id) sharedInstance
{   
   if(!singleton)
    {
        singleton = [self new];
    }
    return singleton;
}
+ (void)resetSingleton
{
    [singlelton release];
    singleton = nil;
}
