在iOS中支持交互式样机原型的最简单方法是？

buttonsOnPage

buttonPressed:

- (void)initButtons
{
    NSMutableArray *page;
    UIButton *button;

    buttonsOnPage = [[NSMutableArray alloc] init];

    // Page 0
    page = [NSMutableArray array];

    button = [UIButton buttonWithType:UIButtonTypeCustom];
    [button addTarget:self action:@selector(buttonPressed:) forControlEvent:UIEventTouchUpInside];
    [button setTag:5]; // When pressed, go to page 5.
    [button setFrame:...];
    [page addObject:button];
    ...
    [buttonsOnPage addObject:page];

    ...
}

- (void)setUpPage:(NSUInteger)page
{
    // Remove all previous buttons
    for (UIView *view in [myImageView subviews]) {
        [view removeFromSuperview];
    }

    for (UIButton *button in [buttonsOnPage objectAtIndex:page]) {
       [myImageView addSubview:button];
    }

    // Also set the correct image.
}


- (void)buttonPressed:(id)sender
{
    [self setUpPage:[(UIView *)sender tag]];
}

#define NEW_BUTTON(page, x, y, width, height) \\
    do {
        button = [UIButton buttonWithType:UIButtonTypeCustom]; \\
        [button addTarget:self action:@selector(buttonPressed:) forControlEvent:UIEventTouchUpInside];\\
        [button setTag:page]; \\
        [button setFrame:CGRectMake(x, y, width, height)]; \\
        [page addObject:button];
    } while (0);

// Page 0
page = [NSMutableArray array];
NEW_BUTTON(1, 10, 20, 20, 20);
NEW_BUTTON(2, 10, 60, 20, 20);
