Hi Jedis,
Here is my problem: my application now have a main nib file
MovieDocument.nib with its FileOwner MovieDocument.mm(We used
AVCVideoServices which requires to be in a c++ source file). I need to
send messages to the methods in MovieDocument.mm from other classes in
the project(I have many other windows and also corresponding
controllers), so i need a way to access the movieDocument globally.
One example: there is another controller VideoController.m which
contains some measurement methods on the movie loaded in
movieDocument. Once we finish the measurement in VideoController, we
need to update the movie in MovieDocument, where we need to send
message to the methods in MovieDocument.
This is from VideoController.m
- (void)writeMeasureOutput:(MeasureView *)sender
{
// Some measurement code here...
object = [[movieDocument measureView] whatsNext];
NSLog(@"Next measurement: %@",object);
}
Such calls should be used in many other controllers in the projects.
So the instant of MovieDocument should be accessed globally.
I have tried to instantiate MovieDocument in MovieDocument.h, but it
is clearly wrong since when the header file is imported, the instant
will be created once.
So any suggestion on this problem? Thanks in advance!
