number pad keyboard not show return key in iphone

Question

I am new to iPhone technology. I've saved a problem in a iPhone application, but when i use textfield keyboard type number pad the keyboard doesn't show a return/done button.

How can I hide the number pad keyboard after entering the number in the textfield? Do you have any solutions for that. Please provide help.

You can do this in this way:

@property (nonatomic, strong) UITextField *textField;

- (void)viewDidLoad {
    [super viewDidLoad];

    self.textField = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, 100, 40)];
    UIBarButtonItem *doneItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(doneButtonDidPressed:)];
    UIBarButtonItem *flexableItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:NULL];
    UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, [[UIScreen mainScreen] bounds].size.width, [[self class] toobarHeight])];
    [toolbar setItems:[NSArray arrayWithObjects:flexableItem,doneItem, nil]];
    self.textField.inputAccessoryView = toolbar;
}

- (void)doneButtonDidPressed:(id)sender {
    [self.textField resignFirstResponder];
}

+ (CGFloat)toolbarHeight {
    // This method will handle the case that the height of toolbar may change in future iOS.
    return 44.f;
}
