Let's say I have a class called SomeClass with a string property name:
@interface SomeClass : NSObject{
NSString* name;
}
@property (nonatomic, retain) NSString* name;
@end
I understand that name may be assigned a NSMutableString in which
case this
will may to errant behavior.
(1) For strings in general, is it *always* a good idea to use the
"copy"
attribute instead of "retain"?
Yes
(2) Is a "copied" attribute in any way less efficient than such a
"retain-ed" attribute?
No, as the string will be retain if it is immutable (the copy
operation is optimized to return [self retain])
