Question

Hello everyone,
I need help on creating a button like in the above picture.
They are multiple buttons that are used to switch to another view and the next button to show a hidden button.

I ‘d like to know which UI Control to use.
Whichever free ready-to-use control or code example is preferred.

Thank you very much.

I did what Mayur Joshi’s suggestion but don’t understand why I can’t scroll buttons in scrollview and there’s no text on buttons.

This is my code

- (void)viewDidLoad
{
    [super viewDidLoad];




    [scrollView setContentSize:CGSizeMake(500.0f, 50.0f)];
    [self.view addSubview: scrollView];

    UIButton *button1 = [UIButton buttonWithType: UIButtonTypeRoundedRect];
    [button1 setTitle:@"Button1" forState:UIControlStateNormal];

    [button1 setFrame:CGRectMake(0.0F, 0.0F, 100.0F, 50.0F)];
    [scrollView addSubview:button1];
    [button1 release];


    UIButton *button2 = [UIButton buttonWithType: UIButtonTypeRoundedRect];
    [button2 setTitle:@"Button2" forState:UIControlStateNormal];

    [button2 setFrame:CGRectMake(100.0F, 0.0F, 100.0F, 50.0F)];
    [scrollView addSubview:button2];

    [button2 release];


    UIButton *button3 = [UIButton buttonWithType: UIButtonTypeRoundedRect];
    [button3 setTitle:@"Button3" forState:UIControlStateNormal];

    [button3 setFrame:CGRectMake(200.0F, 0.0F, 100.0F, 50.0F)];
    [scrollView addSubview:button3];

    [button3 release];

    UIButton *button4 = [UIButton buttonWithType: UIButtonTypeRoundedRect];
    [button4 setTitle:@"Button4" forState:UIControlStateNormal];

    [button4 setFrame:CGRectMake(300.0F, 0.0F, 100.0F, 50.0F)];
    [scrollView addSubview:button4];

    [button4 release];

    UIButton *button5 = [UIButton buttonWithType: UIButtonTypeRoundedRect];
    [button5 setTitle:@"Button5" forState:UIControlStateNormal];

    [button5 setFrame:CGRectMake(400.0F, 0.0F, 100.0F, 50.0F)];
    [scrollView addSubview:button5];

    [button5 release];

Just remove the release methods from the buttons and you are good to go.

Actually, when you declare the buttons with

 UIButton* btn1 = [UIButton buttonWithType: UIButtonTypeRoundedRect];

it is already in auto-release mode as its a class method and not a static method. So you dont need to write

 [btn1 release];
