Is there a way in xcode 4 to list all delegate functions and automatically add the code snippet to a file?

Question

This seems like an obvious feature that should be there but i can't find it.

For example if my class is a uitableviewdelegate whats the quickest way for me to see all the available delegate methods and add the ones im interested in to my implementation file?

You can use the tip in the first link that Simon posted above to get the method signatures for a delegate. After that, adding the code is up to you.

What I like to do is to choose the delegate methods that I most often use, and add them to a code snippet.

For example, for UITableViewDatasource I have a snippet called "UITableView Datasource Required Methods" containing:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *cellIdentifier = @"myCellName";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:cellIdentifier] autorelease];
    }

    //customize cell before showing it

    return cell;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return <#numRow#> ;
}

Then I drag that snippet into my code whenever I'm creating a table delegate.

Is there a way in xcode 4 to list all delegate functions and automatically add the code snippet to a file?
