RAExpendable
NSObject subclass with dynamically added implementations for custom selectors.
What’s Inside
There’s RAExpendable, you use it when you’re dealing with an inline object that needs delegation to work, and would not wish to create separate classes for them, or when you’re dealing with multiple inline objects which are all chatty, and require delegation to cover the whole gamut of their behavior.
Here’s a snippet from its test:
RAExpendable *expendable = [RAExpendable new];
STAssertThrows([expendable performSelector:@selector(foo)], @"object should not answer to selector yet");
[expendable addMethodForSelector:@selector(foo) types:"v@:" block:^{
NSLog(@"Foo");
}];
STAssertNoThrow([expendable performSelector:@selector(foo)], @"object should answer to selector");
