Xcode: How to refactor/rename method and ADD (or REMOVE) its PARAMETERS?

Question

Is Xcode 5 able to change method's signature? As far as I can tell no, but I'd like to be shown wrong.

If I either try to add (or remove) a method's parameter, I am welcomed by the Needs 1 fewer (more) colon to match original error.

Must I really do a manual refactor in this case?

This is not possible with Xcode 6 also. – Bikol

Answer 1

Mark the first method name with the colon ("startRequest:") and then click on Refactor-> Rename

Example:

- (void)startRequest:(NSString *)url with:(NSDictionary *)post

At first, I was taken aback by your suggestion that it matters which part of the method you right-click on (i.e. startRequest: rather than with:), but now I see that you probably misread my question: can you add/remove a parameter? – Shore

No I can't add/remove parameters – Dittmer

Answer 2

As far I have also been unable to find a way to do this. In general Xcode is not very good for refactoring.

Therefore, I want to suggest you to look for other IDEs to use for refactoring. As a matter of fact, this is almost a common approach. I am unable to point you which IDE would be ideal for this though, but there are a few options.
