Problem using sheets (selector not recognized)

07/01/04 10:06
I'm trying to implement sheets into my app except every time the method is called to begin the sheet i get this warning in the console: 2004-01-07 01:57:08.026 PP[672] *** -[NSApplication beginSheet:modalForWindow:modalForDelegate:didEndSelector:contextInfo:]: selector not recognized 2004-01-07 01:57:08.030 PP[672] *** -[NSApplication beginSheet:modalForWindow:modalForDelegate:didEndSelector:contextInfo:]: selector not recognized

- (IBAction)openSaveSheet:(id)sender
{
SEL selector = @selector(sheetDidEnd:returnCode:contextInfo:);

[NSApp beginSheet:saveSheet
modalForWindow:[self window]
modalForDelegate:self
didEndSelector:selector //@selector(sheetDidEnd:returnCode:contextInfo:)
contextInfo:NULL];
}
- (IBAction)clearProjectile:(id)sender
{
}

- (IBAction)saveProjectile:(id)sender
{
[saveSheet orderOut:sender];
[NSApp endSheet:saveSheet returnCode:1];
}

- (IBAction)cancelSave:(id)sender
{
[saveSheet orderOut:sender];
[NSApp endSheet:saveSheet returnCode:0];
}

- (void)sheetDidEnd:(NSWindow *)sheet returnCode:(int)returnCode contextInfo:(void *)contextInfo
{
if (returnCode == 1) {
NSLog(@"user chose to save");
}
else {
NSLog(@"user chose to cancel");
}
[saveSheet orderOut:nil];
}
Any suggestions would be greatly appreciated :-) -John Przyborski Answer: The correct signature of method is
- (void)beginSheet:(NSWindow *)sheet modalForWindow:(NSWindow *)docWindow modalDelegate:(id)modalDelegate didEndSelector:(SEL)didEndSelector contextInfo:(void *)contextInfo
see
modalDelagate
where you typed
modalForDelegate
.
I've been trying to resolve this problem with no luck. Here is my code:
