I have the method:
- (NSInteger)tableView:(UITableView*)tableView numberOfRowsInSection:(NSInteger)section
This seems not very nice, but you can right-click on method name, then
Refactor -> Rename and
Cmd+C to copy method name.
For even better access you can set the shortcut for this in
Xcode -> Preferences -> Key Bindings -> Rename. That will require one click on method name and two shortcuts for getting signature
