getters and setters for custom classes

If you synthesize a custom class, do getters and setters get created for it?

This is the custom class I created.

//  MyClass.h
#import <Foundation/Foundation.h>


@interface MyClass : NSObject <NSCoding> {
    NSString *string1;
    NSString *string2;

}
@property (nonatomic, retain) NSString *string1;
@property (nonatomic, retain) NSString *string2;

@end

Here I declare an object of that class as a property

//  DetailViewController.h


#import <UIKit/UIKit.h>
#import "MyClass.h"


@interface DetailViewController : UIViewController {

    MyClass *myObject;
}
@property(nonatomic, retain) MyClass *myObject;

@end

Here I synthesize the object.

#import "DetailViewController.h"
#import "MyClass.h"


@implementation DetailViewController
@synthesize myObject;

So does it have getters and setters?

When I try to run this code inside RootViewController.m

DetailViewController.myObject = [theArray objectAtIndex:indexPath.row];

I get an error saying "Accessing unkown 'setMyObject:' class method. Object cannot be set - either readonly property or no setter found.'

Only if you declare the desired instance variables as properties, then synthesize propname;, will getters and setters be created. Now, what kind of code goes into the getters and setters depends on what property attributes you define (nonatomic/atomic, assign, retain, copy)

EDIT to OP's revised question: Yes a getter/setter will be created for the myObject instance variable of the DetailViewController class

DetailViewController.myObject = [theArray objectAtIndex:indexPath.row];

You are attempting to set a class variable that isn't defined. DetailViewController is of type Class, not DetailViewController. Perform the same operation on an instance of DetailViewController and you should be all set.
