I've created some key-value bindings through IB to connect an
NSImageView subclass (myImageView) to an NSArrayController
(myArrayController).
I set up the valueURL of the myImageView as
myArrayController.selection.URLToPDFFile.
Now I'm trying to use drag and drop of a file from the Finder to set
this value. The drag and drop code is in myImageView. Here's a snippet:
if ( [[pboard types] containsObject:NSFilenamesPboardType] ) {
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:[[pboard
propertyListForType:NSFilenamesPboardType] objectAtIndex:0]];
[myArrayController setValue:fileURL forKey:@"selection.URLToPDFFile"];
[fileURL autorelease];
return YES;
}
I always get the following error when I try the drag and drop:
[<myArrayController 0x345310> setValue:forUndefinedKey:]: this class is
not key value coding-compliant for the key selection.URLToPDFFile
Shouldn't it be key-value compliant if I set up the bindings in IB? Do
I have to set them up again programmatically? Or am I just completely
missing the point?
