macOS Splitting code into 2 parts in obj-C (newbee)

[dova]

Hello,
I am totally new in Objective-C and trying to learn this language:
I would like to split the following code into 2 parts:

MySaveMenuController.h > contains code to open OpenPanel
MySaveMenuController.m > contains code to open OpenPanel

and
DisplayTextField.h > contains code to open textField with tvarFilename after opening OpenPanel
DisplayTextField.m > contains code to open textField with tvarFilename after opening OpenPanel

How i can do this?
Thank you


MySaveMenuController.h

//  MySaveMenuController.h
//  Example

#import <Cocoa/Cocoa.h>


@interface  MySaveMenuController : NSObject {
	IBOutlet NSTextField *textField;
} 
- (IBAction)doOpen:(id)pId;

@end

MySaveMenuController.m

//  MySaveMenuController.m
//  Example

#import "MySaveMenuController.h"

@implementation MySaveMenuController


- (IBAction)doOpen:(id)pId; {	
		NSLog(@"doOpen");	
		NSOpenPanel *tvarNSOpenPanelObj	= [NSOpenPanel openPanel];
		NSInteger tvarNSInteger	= [tvarNSOpenPanelObj runModalForTypes:nil];
		if(tvarNSInteger == NSOKButton){
			NSLog(@"doOpen we have an OK button");	
		} else if(tvarNSInteger == NSCancelButton) {
			NSLog(@"doOpen we have a Cancel button");
		} else {
			NSLog(@"doOpen tvarInt not equal 1 or zero = %3d",tvarNSInteger);
		} // end if		

		NSString * tvarDirectory = [tvarNSOpenPanelObj directory];
		NSLog(@"doOpen directory = %@",tvarDirectory);
		NSString * tvarFilename = [tvarNSOpenPanelObj filename];
		NSLog(@"doOpen filename = %@",tvarFilename);
	
	


	[textField setStringValue:tvarFilename]; // this should be splitted in to the new file:

	
} // end doOpen

@end

You may want to clarify what you are trying to do. I've read your post twice over two days and still don't understand your goal.
