ios - How to assign a new class in existing class?

I'm new to iPhone development,I want to assign one class in existing class

This is what declare in C#

public partial class UserRegisteration : System.Web.UI.Page
{
//some methods

public class Mime
{
//some methods
}
}

like the above format in Objective-C how to assign one more class in existing class?

Any ideas? Thanks in advance.

Yes you can.I am using one class in existing class . One is extending UIView and other is extending NSObject.

MultiLayout.h

    @interface MultiLayout  : UIView
    {
   // methods and properties
    }

    @end

    @interface SingleControl : NSObject
    {
   // methods and properties
    }

    @end

MultiLayout.m

@implementation SingleControl

//methods and variables declaration and property synthesization

@end

@implementation MultiLayout

//methods and variables declaration and property synthesization

@end

For getting the static value of SingleControl in MultiLayout . you have to call class method like:

MultiLayout.h

 @interface  MultiLayout : UIView
    {
   // methods and properties
    }

    @end

    @interface SingleControl : NSObject
    {
   // methods and properties
    }

   // add class method
   +(int)getValue;

    @end

MultiLayout.m

    @implementation SingleControl

    // add static value 
    static int values = 100;


    // implement method

   +(int)getValue{
    return values;
    }

    @end

    @implementation MultiLayout

    // call method to get value

     [SingleChoiceControl getValue];

    @end

If I understand your question correctly, you would do this in your interface file:

@interface Mime 

//properties and method declarations

@end

@interface UserRegistration : System.Web.UI.Page

@property (strong, nonatomic) Mime *mimeInstance;

@end

and then in the implementation file you implement both like so:

@implementation Mime 

//implementation

@end

@implementation UserRegistration

//implementation

@end
