I am quite confounded with regard to how/when to allocate outlets which
are classes existing as instances in
another class. Consider
@interface SpriteController : NSWindowController {
IBOutlet SpriteView* spriteView;
IBOutlet NSWindow* spriteWindow;
}
SpriteController* spriteController;
- (id)spriteWindow;
- (id)spriteView;
-(void)setSpriteView:(SpriteView*)view;
}
SpriteView is defined in another subclass as:
@interface SpriteView: NSView
{
NSImage *spriteImage;
}
SpriteController and SpriteView are defined and connected in the NIB
When I open the NIB with
-(void)loadSpriteController{
if (spriteController == NULL) {
spriteController = [[SpriteController alloc] init];
if (![NSBundle loadNibNamed:@"spriteWindow"
owner:spriteController]) {
NSLog(@"Error loading SpriteController");}
else{
NSLog(@"SpriteController NIB Loaded");
}
}
}
spriteController gets a pointer, but spriteView is NIL. All subsequent
messages to spriteView are
messages to NIL
How/where should I be allocating spriteView. I've tried adding:
[self setSpriteView: [[SpriteView alloc] init]];
to loadSpriteController with no consequence. spriteView gets a pointer but
[[spriteController spriteView] drawRect:[[spriteController
spriteWindow] bounds]];
does not get to drawRect
