Trying to convert an older project to Arc, Xcode complains about "Use of undeclared identifier '_privateDate'".
And threatens that nothing will be done unless I fix this first.
Well - for one: without Arc there are no undeclared identifiers. (Builds without error or warnings).
The class with problems looks like:
@interface SomeClass( )
@property (strong) NSDate *privateDate;
@end
@implementation SomeClass
- (id)initAt:(NSDate *)someDate ;
{
self = [ super init ];
if ( self == nil ) return nil;
_privateDate = [ someDate retain ];
return self ;
}
... some other stuff omitted ...
@end
I always thought that using accessors (like self.privateDate) in init methods was NOT a good idea, because at this point the thing might not be completely initialised and functional, so one had better use _privateDate directly.
And the accessor methods like setPrivateDate: might rely on a completely functional object.
Is this correct?
How to placate Xcode?
Gerriet.
