Apple's Cocoa Memory Management Programming guide shows this
pattern for init:
- (id)init {
if ((self = [super init])) {// superclass may return nil
// your initialization code goes here
}
return self;
}
Newb question: In the case of
id myObject = [[MyObject alloc]init];
what happens to the allocated memory if the [super init] fails and
how do I handle it since I dont have a self to release?
If [super init] fails it should have done [self release] before
returning nil.
Okay so somewhere along the chain up to NSObject, some class in the
hierarchy is responsible for issuing [self release] within it's
aborted init. But just theoretically if it does go all the way up to
NSObject which fails its init, is it's alloced memory leaked? Not
that it will ever happen...
