Question

我在

中的NSMutableArray分配中遇到内存泄漏

NSMutableArray *contactsArray =[[NSMutableArray alloc] init];

CODE：

+(NSMutableArray*)getContacts
{
    addressBook = ABAddressBookCreate();

    NSArray* peopleArray =  (NSArray*) ABAddressBookCopyArrayOfAllPeople(addressBook);

    int noOfPeople = [peopleArray count];

    NSMutableArray *contactsArray =[[NSMutableArray alloc] init]; 

    for ( int i = 0; i < noOfPeople; i++)
    {
        ABRecordRef person =   [peopleArray objectAtIndex:i];
        ABRecordID personId = ABRecordGetRecordID(person);
        NSString* personIdStr = [NSString stringWithFormat:@"%d", personId];

        ContactDTO* contactDTO = [AddressBookUtil getContactDTOForId:personIdStr];


        [contactsArray addObject:contactDTO];

    }
    [peopleArray release];
    return contactsArray;

}

Answer 1

从方法返回的对象（在您的情况下，contactsArray）是返回之前自动释放的标准过程。您可以return [contactsArray autorelease];创建它，也可以使用[NSMutableArray arrayWithCapacity:noOfPeople]

自动释放它

Answer 2

您需要在某处手动释放contactsArray，因为它没有定义自动释放。
