Steve,
Thanks for your reply.
Seems that does not help.
In my NSPersistentDocument subclass I created a new initializer, which stripped
of error checking, is basically:
- (instancetype)initWithTemplate
{
self = [super init];
[self readFromURL:<hidden file in my .app>
ofType:@"com.rogue-research.foobar"
error:&error];
[self setFileURL:nil]; // seems to change nothing
return self;
}
Indeed I get what looks like a new/untitled document and it has the correct
contents from the template file. When I save I get a save panel and supply a
filename for example on the Desktop but then it tries to save to my template
anyway with an exception:
NSUnderlyingException = "Cannot update objects into a read only store.";
readFromURL: seems to have added my template as a persistent store in the
persistent store coordinator. :(
Cheers,
