Here's a sample snippet of my code:
- (NSDate *)offsetDate:(NSDate *)fromDate
byYears:(int)addYears
byMonths:(int)addMonths
byDays:(int)addDays {
NSDateComponents *offset = [[NSDateComponents alloc] init];
[offset setYear:addYears];
[offset setMonth:addMonths];
[offset setDay:addDays];
NSCalendar *gregorian = [[NSCalendar alloc]
initWithCalendarIdentifier:NSGregorianCalendar];
return [gregorian dateByAddingComponents:offset toDate:fromDate
options:0];
}
Builds and runs just dandy .. but "Build and Analyze" coughs up:
// method returns an object with a +1 retain count (owning reference)
NSDateComponents *offset = [[NSDateComponents alloc] init];
... and at the end of the method:
// object allocated and stored into 'offset' is no longer referenced
after this point
// and has a retain count of +1 (object leaked)
}
It appears that the analysis is saying I should retain offset immediately after
it is set with *offset =:
NSDate *result = [gregorian dateByAddingComponents:offset toDate:fromDate
options:0];
[offset release];
return result;
By the way, identical gotchas are picked up by B & A for gregorian.
