Question

My app gives a low memory crash on the device and not on the simulator.I used Instruments and i think that the problem lies in the following part

       UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];

       [button setBackgroundImage:[UIImage imageNamed:@"gembtnblu.png"]  forState:UIControlStateNormal];<br>

        button.frame = CGRectMake(0, 0, TOOLBAR_BUTTON_WIDTH , TOOLBAR_BUTTON_HEIGHT);<br>

        [button setTitle:[NSString stringWithFormat:@"%c",choice] forState:UIControlStateNormal];<br>

        [button setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];

        [button addTarget:self action:@selector(ChoiceButtonTouched:) forControlEvents:UIControlEventTouchUpInside];

        [button setTag:choice];

        UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithCustomView:button];

        //Add button to the array
        [tempItems addObject:customBarItem];

        if (isReviewing == TRUE) {
            customBarItem.customView.userInteractionEnabled=FALSE;
        }
        //release buttons
        [customBarItem release];

        numberOfChoices++;

But im not able to spot the problem.Please help guuys, i have beeen stuck at this for days now

heres some more code


NSArray *items=[[NSArray alloc] initWithArray:(NSArray *)tempItems];
[tempItems release];

//add array of buttons to toolbar
[toolbar setItems:items animated:YES];
[self.view addSubview:toolbar];

the static analyser says that theres a potential leak with ‘items’ array.But if i put in a release statement, the app crashes

Answer 1

Did you release the toolbar after adding it as a subview? If you did not, and are not releasing the toolbar in the dealloc, there’s your leak.
