| Lets say I have a simple method...
method.h ...
@interface Method : NSObject { NSDate *date; } -(id)init; -(void)setNewDate:(NSDate *)date;
@end
method.m ... @implementation Method
//Init Methods -(id)init { self = [super init]; date = [[NSDate dateWithTimeIntervalSinceReferenceDate:0] retain]; <<< see below for question return self; } -(void)setNewDate:(NSDate *)newDate { [NewDate retain]; [date release]; date = newDate; } @end
Question: The line .... date = [[NSDate dateWithTimeIntervalSinceReferenceDate:0] retain]; date must be retained, yet, retaining it, sets the retain count to 2.
This does not make sense to me. Why should the retain count have to be 2? As only one object references date.
