Folks;
I use an object in my application called 'appDelegate'; it's a
subclass of NSObject.
I instantiate this object in the main Nib file
This object has IBActions for the main menu and since it is -app
delegate it is a kind on central dispatcher.
My question is this:
The +initialize is run twice when the app loads:
2009-03-16 20:21:42.690 XYZ[6676:813] *[AppDelegate initialize]
2009-03-16 20:21:42.781 XYZ[6676:813] *[NSKVONotifying_AppDelegate
initialize]
Once for the object itself and then again as the instance in the Nib.
That's how I read this. Is that wrong?
So I wonder if this is wasteful. I don't really want to run
initialize twice.
It kind of torques my notion of a class that +initialize is run twice
but I try and just play along....
I don't see how to use this IBActions and IBOutlets without
instantiating.
Is the correct thing to do here break this object into smaller objects?
Thanks for any clarifying comments
Steve
+initialize {
//check minimum system OS - so I can gracefully tell the user what is
deal is and how they should upgrade - if not min then die
//check whether or not the app has access to the ~/Library/Application
Support - if not then die
//test for keyDown - to flip the logging level
}
- init {
//set this object as app delegate
[[NSApplication sharedApplication] setDelegate:self];
//NSFormatters and NSValueTransformers which must be done here so
awakeFromNib binding transformers are set
[self setupApplicationBehavior];
//hang onto the prefPath
prefFile = [[[[NSSearchPathForDirectoriesInDomains(NSLibraryDirectory,
NSUserDomainMask, YES) objectAtIndex:0]
stringByAppendingPathComponent:@"Preferences"]
stringByAppendingPathComponent:[[[[NSBundle mainBundle]
infoDictionary] valueForKey:@"CFBundleIdentifier"]
stringByAppendingString:@".plist"]] retain];
//determine if this is the first time prefs have been used
firstPrefUse = (![[NSFileManager defaultManager]
fileExistsAtPath:prefFile]);
//load userPrefs here so they can be used by -awakeFromNib
userDefaults = [[NSUserDefaults standardUserDefaults] retain];
[self registerFactoryDefaults];
return self;
