objc-forbidden-subclassing
|
||
|
|
==========================
|
||
|
|
|
||
|
|
Finds Objective-C classes which are subclasses of classes which are not designed
|
||
|
|
to be subclassed.
|
||
|
|
|
||
|
|
By default, includes a list of Objective-C classes which are publicly documented
|
||
|
|
as not supporting subclassing.
|
||
|
|
|
||
|
|
.. note::
|
||
|
|
|
||
|
|
Instead of using this check, for code under your control, you should add
|
||
|
|
``__attribute__((objc_subclassing_restricted))`` before your ``@interface``
|
||
|
|
declarations to ensure the compiler prevents others from subclassing your
|
||
|
|
Objective-C classes.
|
||
|
|
