Thanks for the response, but, still not working.
Here's in more detail what I'm trying to do. My main window is controlled by
MyAppDelegate:
@interface MyAppDelegate : NSObject <NSApplicationDelegate>
In MyAppDelegate I respond to an IBAction to open a second window to generate
some data that needs to be go back to MyAppDelegate to put in my model. The
second window is controlled by MyDataWindowController, a subclass of
NSWindowController.
- (IBAction)showDataWindow:(id)sender
{
MyDataWindowController *searchDataWindow = [[MyDataWindowController alloc]
initWithWindowNibName:
@"searchDataWindow"];
[NSApp beginSheet:[searchDataWindow window]
modalForWindow:[self window]
modalDelegate: self
didEndSelector: nil
contextInfo: NULL];
}
This all goes fine, the sheet opens and I get generate the data, stored in an
NSDictionary in MyDataWindowController. Now I want somehow to get the data
back to MyAppDelegate. So I am trying this in MyDataWindowController:
At the top of MyDataWindowController I add this @protocol:
@protocol MyDataWindowControllerDelegate <NSObject>
- (void)insertData: (NSMutableDictionary *)data;
@end
and then after the data is obtained:
id <MyDataWindowControllerDelegate> del = [self delegate]; //
<-------
if ([del respondsToSelector:@selector(insertData:)])
{
[del insertData: data];
}
}
[NSApp endSheet: [self window] returnCode: 1];
[[self window] orderOut: self];
Which now gives the warning:
Semantic Issue: Instance method '-delegate' not found (return type defaults to
'id') on the line with the arrow.
Any suggestions how to make this work? Maybe not use a delegate?
Thanks,
- Koen.
