What's the best way to get the notification from the iTunesConnection
object within the controller class?
Use bindings. You can either set it up in Interface Builder, or do it
in code:
- (void)awakeFromNib
{
iTunesConnection *connection = [[iTunesConnection alloc] init];
#warning Leaking connection
[currentTrackField bind:@"value"
toObject:connection
withKeyPath:@"currentTrack"
options:0];
}
Also, unless you're writing this for Leopard, your code has
absolutely no memory management. It will not take kindly to that.
There is plenty of good documentation around on that, so I won't make
a sub-par effort here.
@interface iTunesConnection : NSObject
{
NSString *currentTrack;
}
- (id) init;
- (void) updateNow:(NSNotification *)notification;
- (void) updateCurrentTrackName;
- (NSString *) getcurrentTrack;
- (void) setCurrentTrack:(NSString *) curTrack;
@end
Change the name of -getcurrentTrack to -currentTrack. "The 'get'
prefix has a very specific meaning in Cocoa-derived APIs: It means
that you're going to be passing in a location by reference where the
result should be stored." -- Chris Hanson
Have fun,
