Is `super` local variable?
- by Michael
// A : Parent
@implementation A
-(id) init
{
// change self here then return it
}
@end A
A *a = [[A alloc] init];
a. Just wondering, if self is a local variable or global? If it's local then what is the point of self = [super init] in init? I can successfully define some local variable and use like this, why would I need to assign it to self.
-(id) init
{
id tmp = [super init];
if(tmp != nil) {
//do stuff
}
return tmp;
}
b. If [super init] returns some other object instance and I have to overwrite self then I will not be able to access A's methods any more, since it will be completely new object? Am I right?
c. super and self pointing to the same memory and the major difference between them is method lookup order. Am I right?
sorry, don't have Mac to try, learning theory as for now...
