NSNotification center may not respond to -object ?
- by blackkettle
Hi,
I'm trying to make simple use of the NSNotification center inside my iPhone application, but I seem to be doing something wrong in this case. I was under the impression that it was possible to retrieve an object associated with a particular message, or at least a reference to the object, but using the following example code I'm getting a warning,
"NSNotification center may not respond to -object"
- (void)addNewBookmark:(NSNotificationCenter *)notification {
Bookmark *newBookMark = (Bookmark *)[notification object];
//Do some stuff with the bookmark object
}
Indeed, when I compile and run the code, basically nothing I try to do with the contents of the object actually gets carried out - it's simply ignored.
The post code is as follows,
- (IBAction)save:(id) sender{
//Sending the message with the related object
[[NSNotificationCenter defaultCenter]
postNotificationName:@"addNewBookmark"
object:bookmark];
}
and the bookmark object itself is just a dictionary. I also tried using the "userInfo" argument and passing the bookmark object through that, but the result was the same.
How should I be doing this? What am I doing wrong?
