How to supress a "Class may not respond to '-method' warning with variable method name?

Question

How can I prevent this warning with a variable selector name?

NSString *methodName;

SEL method = NSSelectorFromString(methodName);

if ([self respondsToSelector:method]) {

    if ([methodName hasSuffix:@":"])
        [self method:dict];
    else
        [self method];

}

Answer 1

Use

[self performSelector:method];

Instead of

[self method];

And

[self performSelector:method withObject:dict];

Instead of

[self method:dict];
