如何在iOS中制作水平滚动菜单 [英] how to make horizontal scrolling menu in iOS

问题描述

我想制作一个水平滚动的菜单。

I would like to make a menu which will have horizontal scrolling.

该菜单共包含16个类别。所以我计划在第一部分拿8分，在另一部分拿8分。

The menu contains total 16 categories. So I am planning to take 8 on first part and rest 8 on another part.

有人可以让我了解需要做什么吗？

Can some-one give me insight of what needs to be done?

我相信我需要在下面使用。

I believe I need to use below.

UIScrollView
Add buttons in this scrollview

这就是它？

我想要的是第一个屏幕8个按钮，其中第一个屏幕将有两行，每行设置4个按钮。

What I want is on first screen 8 buttons where first screen will have two rows with 4 buttons set on each row.

推荐答案

如果您所做的只是向水平滚动视图添加按钮，您将执行以下操作...

If all you're doing is adding buttons to a horizontal scroll view you would do something like follows...

- (void)createScrollMenu
{
    UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 100)];

        int x = 0;
        for (int i = 0; i < 8; i++) {
            UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(x, 0, 100, 100)];
            [button setTitle:[NSString stringWithFormat:@"Button %d", i] forState:UIControlStateNormal];

            [scrollView addSubview:button];

            x += button.frame.size.width;
        }

        scrollView.contentSize = CGSizeMake(x, scrollView.frame.size.height);
            scrollView.backgroundColor = [UIColor redColor];

       [self.view addSubview:scrollView];
    }

这将创建一个高度为100，宽度与其一样大的滚动视图父，并添加8个按钮。

This will create a scrollview with a height of 100, width as big as its parent, and add 8 buttons to it.
