Question

I want to use class method for selector of action of UIBarButtonItem.

The code is:

[[UIBarButtonItem alloc] 
    initWithTitle:@"title"                                            
    style:UIBarButtonItemStylePlain
    target: self
    action:@selector(method)]

When I use instance method for action, it works.

But when I use class method for action, a error happens when I tap the button.
The error message is: unrecognized selector sent to instance.

Can’t I use class method for this?
How can I set use for target, instead of self?

Answer 1

Please change to the following code:
here the target should be self instead of [self class]

[[UIBarButtonItem alloc] initWithTitle:@"title"
                                 style:UIBarButtonItemStylePlain
                                target:self
                                action:@selector(method)];
