I am very new to iPhone. I have developed two version of an application in iphone. Here i have used individual class implementations depends upon version features.

For example ' ListViewController' class have .h,.m, xib files. with the same name in two versions, but different in some part (little bit difference) code implementation.

In 1st 'ListViewController' version shows only a table view. In 2nd version 'ListViewController' shows tableview and a button just bello the table view, to set the reminders (alarm).

So just the difference in InterfaceBuilder *button* (AlarmButton) & in Code button action -(IBAction)SetReminder.

Now I need to put all the same classes in a library (Common folder) for the two projects v1&v2,

Now i need to implemente 'ListViewController' as common for both versions using subClassing.

How do I achieve that, any help or examples or link.

• iphone
• objective-c
• xcode
• shared-libraries
• subclassing

To share the same code between classes generally we use inheritance but there is a very cool feature added in objective-c that is category, find the tutorial link below: http://iphone-obsessed.blogspot.in/2010/05/tutorial-creating-class-categories-in.html

Might Help...!!

To create a subclass you just need to create header and implementation files they should look like this

// header file
@interface MySubclassName : ListViewController

@end


// implementation file
#import "MySubclassName.h"
@implementation MySubclassName

// methods you want to subclass

@end
