Greetings little elves, all busy toiling away on MCCA's,
I have a quick question, :) , about dynamically loading classes using
NXBundle.
The bundle directory from which I would like to load is separate from my
main bundle. This bundle directory consists of an interface file,
PositioningMap.nib (inside the English.lproj dir), executable code,
PositioningMap, and a tiff file. The whole bundle directory is called
PositioningMap.framework. The executable code is made up of a single class
called PositioningMap, a view subclass.
I made PositioningMap.m the nib file's owner. Everything compiles fine
as a bundle in ProjectBuilder.
From my application, I can load the nib file, but for some reason I can't get
it to load in the PositioingMap view. In the console, it says:
Dec 22 22:02:07 localhost ConceptBoard[3348]: objc: class `PositioningMap'
not linked into application
Here's a snippet of code:
// The following seems to work fine
if (myBundle = [[NXBundle alloc] initForDirectory:bundlePath]) {
printf("Seem to have gotten myBundle OK\n");
}
// This does not give me the Celebrate message
classObj = [[[myBundle classNamed:PositioningMap] alloc] initFrame:NULL];
if (classObj) {
printf("Celebrate good times, c'mon...\n");
}
// And the following seems to work
if ([myBundle getPath:buf forResource:"PositioningMap" ofType:"nib"]) {
loadedNib = [NXApp loadNibFile:buf owner:NXApp withNames:NO
fromZone:[NXApp zone]];
}
This is when I get the `PositioningMap' not linked into application message
on the Console.
Any comments back would be appreciated. This is for a Thesis demonstration.
If the the question seems trivial, please forgive, I'm a designer, not
a CS guru...
