if I have a property
@property (nonatomic, retain) NSArray* myArray;
Can I do ? And if yes why does this work ?
for (id object in self.myArray)
;
Or do I need to do ?
NSArray* r = self.myArray;
for (id object in r)
;
It works because self.myArray is syntactical sugar for [self myArray], which is generated by the @synthesize keyword. So really you’re doing:
And the return value of [self myArray] implements the fast enumeration protocol so the for..in syntax can work on it.
Does that make things clearer?
