Question

I have a subclass of UIView, that have inherited the - initWithFrame: method. However, I don’t want that method to be called on my subclass.
Is there any way to “delete” that method on my subclass?

Answer 1

Don’t implement it and don’t call [super initWithFrame:aRect]. Just call doesNotRecognizeSelector: with the _cmd argument:

- (id)initWithFrame:(CGRect)aRect
{
    [self doesNotRecognizeSelector:_cmd];
}

If the method does not return void, you will receive a warning from the compiler:

Control reaches end of non-void function.

To “remove” this warning, add return self; (in this case) as the last line to make the compiler happy. It will never be reached at runtime because doesNotRecognizeSelector: raises a NSInvalidArgumentException exception.
