Question

I am new to iPhone SDK.

I am working with Tabbar based application.it has 5 tabs.named by

• General
• School
• Work
• Favorite
• Contact.

In General tab: I am showing his basic info and about his/her family and friends picture(thumb picture,note that user can upload any number of friends and family photo).

In School tab: List of all that school where he/she studied.he/she can put a single photo(thumb picture) of his/her school.

In Work: It is same as school.

In Favorite: It shows all data (around 20 textfields).

In Contact: It also shows few textfields.

User can edit any tab also.

Now my question is i am playing with tab for 10 mins and after that it is crashing without any warning.It never gives my any kind of acknowledgement.

What should i do now?

Thanks In Advance !

It would be because of memory issue. Release your objects in didReceiveMemoryWarning method instead of dealloc method. Reinitialize the data in viewDidLoad method. Ex:

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
        yesNoLabel = [[UILabel alloc] initWithFrame:CGRectMake(520, 580, 80, 36)];
        [yesNoLabel setFont:[UIFont boldSystemFontOfSize:14.0]];
        [self.view addSubview:yesNoLabel];
    }
    return self;
}

- (void)viewDidLoad
{ 
    [yesNoLabel setText:@"NO"];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    [yesNoLabel release];
}
