I tried to post this last week. Got no response from it, nor did I see
it appear in
the list. If you hav gotten this before, I apologize... but I urgently need
answers to this question.
This came from:
http://developer.apple.com/documentation/Cocoa/Conceptual/ObjectiveC/index.html
Note code below....
#import <Cocoa/Cocoa.h>
struct Class0 { void foo(); };
struct Class1 { virtual void foo(); };
struct Class2 { Class2(int i, int j); };
@interface Foo : NSObject {
Class0 class0; // OK <---- Is this OK because there was no constructor?
Class1 class1; // ERROR!
Class1 *ptr; // OK—call 'ptr = new Class1()' from Foo' init,
// 'delete ptr' from Foo's dealloc
Class2 class2; // WARNING - constructor not called!
...
@end
OK, but I don't see why Class2's constructor is not called. Is that
because it
didn't include the arguments... IE:
Class2 class2(i, j); // WOULD this work?
John
