NAME |
ObjC.unteach - Remove Objective-C methods implemented in JavaScript |
SYNOPSIS |
ObjC.unteach(object, "selector")
ObjC.unteach(object)
ObjC.unteach()
delete object.selector
delete object["selector:selector:..."]
DESCRIPTION |
Removes the JavaScript implementation of the method selector from the Objective-C object or class object, if it was added by the current interpreter. Any former implementation of a selector that was overridden will then reappear.
ObjC.unteach(object) removes all methods of the specified object or class that were added by the current interpreter. ObjC.unteach() will remove all methods that were added by the current interpreter from all objects and classes (this happens automatically if an interpreter is released). The unteach method returns the number of method implementations that were successfully removed. Alternatively to calling the unteach method, you can use JavaScript's delete operator. If the selector contains colons you have to quote it and use array notation. |
EXAMPLE |
js> @teach NSObject test { return "test0" } @end
js> w = [[NSWindow alloc] init]
(NSWindow *)0x32b2f8
js> @teach w test { return "test1" } @end
js> w.test()
test1
js> @teach w test { return "test2" } @end
js> w.test()
test2
js> delete w.test
true
js> w.test()
test1
js> delete w.test
true
js> w.test()
