Question

I have a question regarding setting up a custom delegate class for use with UITableView. What I have done is as follows:

• Setup a new class (in sperate *.h and *.m files for the class)
• Conformed that new class to the <UITableViewDelegate, UITableViewDataSource> protocols
• Added the required methods.
• Created a pointer to the new object using @property and IBOutlet.
• In InterfaceBuilder created and assigned an object template to my new class
• Assigned the dataSource and delegate connections.

This all works fine. My question is if I don’t want to use interfaceBuilder to setup and instantiate my new delegate class how do I go about doing that in Xcode instead? More specifically how would I:

• Instantiate the delegate class, would that be created / owned by the controller?
• Set the dataSource and delegate connections?
• What is the best way of doing this?

Answer 1

In your view controller, create a new instance of the delegate class and assign it to your property, make sure to remove IBOutlet

MyDelegateClass * delegateClass = [[MyDelegateClass alloc] init];
[self setMyProperty:delegateClass];
[delegateClass release];

You can set set your tableview’s delegate and datasource by doing:

[myTableView setDelegate:self.myProperty];
[myTableView setDatasource:self.myProperty];

You should probably put all this in viewDidLoad
