How can I fix this memory leak

Question

If I release the dueDate here I am having BAD_EXCESS in other place of my code. What am I doing wrong here? invoice is a core date object/entity here.

NSDate *deliveryDate = [NSDate dateWithTimeIntervalSinceNow: - oneDayInSeconds * 7];
NSDate *dueDate = [[NSDate date] initWithTimeInterval:(NSTimeInterval) (oneDayInSeconds * 3) sinceDate:deliveryDate]; 
[invoice setDueDate:dueDate];  
//[dueDate release];

Answer 1

Use

[NSDate alloc]

instead of

[NSDate date]

Answer 2

将[NSDate date]更改为[NSDate date]分配[NSDate alloc] 。

Answer 3

As said, change [NSDate date] to [NSDate alloc].

If you are "init"ing you need to "alloc" too.

Alternatively you could do this:

NSDate *dueDate = [NSDate dateWithTimeInterval:sinceDate:]

or even:

NSDate *dueDate = [NSDate date]; dueDate = [NSDate dateWithTimeInterval:sinceDate:]

etc etc... :)
