Question

The Instruments tells me that this piece of code has a leak. However, I am pretty sure I have released it later on. Can anyone tell me what’s going on here?

- (void) addReminderEntry{
    DataEntryController* item = [[DataEntryController alloc] initWithEntryType:REMINDER]; // it says that the leak was instantiated here
    item.delegate = self;
    [[self navigationController] pushViewController:item animated:YES];
    [item setEditing:YES animated:YES];
    [item release];// this is the place I release it
}

Thanks

It turns out that this is caused by this constructor:

- (DataEntryController*) initWithEntryType:(DataType) eType{
    DataEntryController* item = [[DataEntryController alloc] init];//<- here
    item.entryType = eType;
    item.allowEdit = YES;
    return item;
}

Apparently iOS adds retain 1 to each constructor with an initial ‘init’.

It works fine after switching to:

DataEntryController* item = [super init];
