What I miss in Xcode when I write iPhone applications

Posted by – February 24, 2009

One of the missing features in Xcode is the hability to add code sense for protocol methods that can be implemented by a class, for example a class that extends UITableViewController, these classes may have a custom implementation of methods found on both UITableViewDelegate or UITableViewDatasource protocols, the signature of these methods isn’t so easy to memorize and some code completion at this point would help a lot.


A small list of protocol methods signatures that is hard to memorize when working with UITableViews:

1
2
3
4
5
6
//To render table cells
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;
//To return an icon for row selection
- (UITableViewCellAccessoryType)tableView:(UITableView *)tableView accessoryTypeForRowWithIndexPath:(NSIndexPath *)indexPath;
//To return a title for a section in a table
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section;

The example above contains only some methods of UITableViewDelegate protocol, the entire iPhone API has a lot of others protocols, each one with a bunch of methods that can be implemented by developer, if you have a good memory, don’t worry, memorize methods parameters of all protocols that you use will a piece of cake to you, but it isn’t true for me. :D

    In many aspects the Xcode team must learn something from Eclipse team. If you are writing a class in Eclipse that implements a specific interface and you haven’t added any of interface method in this class then Eclipse automatically reports an error and help the user on implement these methods.

    Problem solved with help of this XCode plugin.

    XCode 3.2.1 now can provide code completion for protocol methods.
