Hello,
I have an AppController that looks like this:
AppController.h:
#import <Cocoa/Cocoa.h>
@class PostController;
@interface AppController : NSObject
{
PostController *postController;
NSString *theString;
}
- (IBAction)setString:(id)sender;
- (IBAction)viewString:(id)sender;
- (void)processString;
@end
AppController.m:
#import "AppController.h"
#import "PostController.h"
@implementation AppController
- (IBAction)setString:(id)sender
{
// Is postController nil?
if (!postController) {
// NSLog(@"Post Controller was nil.");
postController = [[PostController alloc] init];
}
// NSLog(@"Showing %@", postController);
[postController showWindow:self];
theString = @"The String";
NSLog(@"Current Selected Site: %@", theString);
[self processString];
}
- (IBAction)viewString:(id)sender
{
NSLog(@"viewString Method: %@", theString);
[self processString];
}
- (void)processString
{
NSLog(@"processString Method: %@", theString);
}
@end
I have two XIB files, MainMenu and NewPost. I've dragged an NSObject into each
XIB, and set it's class to AppController. In MainMenu, I have two buttons, one
bound to the setString action, and one set to the processString action. In
MainMenu XIB, I can see theString in the NSLog output. In the NewPost XIB, I
have one button bound to the processString method, but from this XIB, every
time I run the processString method, theString is null.
How can I define a variable (like NSString) in one XIB, and be able to access
it from methods triggered from another XIB?
I've got a simple Xcode project that shows this problem, if it would help with
explaining it.
Thanks,
Jon
PS. Here is the PostController too, just in case:
#import <Cocoa/Cocoa.h>
@interface PostController : NSWindowController
{
}
@end
#import "PostController.h"
#import "AppController.h"
@implementation PostController
- (id)init
{
if (![super initWithWindowNibName:@"NewPost"])
return nil;
return self;
}
- (void)windowDidLoad
{
NSLog(@"Nib file is loaded!");
}
@end
