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?

Answer 1

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.
