滚动视图内的分段控制

Question

我正在尝试创建一个非常长的分段控制器,让用户在众多选项中进行选择.如何在Scroll View中获取它？

我试过拖放它但它不允许我滚动它.

Answer 1

尝试通过以下代码在滚动视图中添加分段控件:

- (void)viewDidLoad
{
    [super viewDidLoad];

    journals = [[NSMutableArray alloc]init];

    self.tableView.dataSource = self;
    self.tableView.delegate = self;

    UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 49, 320, 29)];
    self.segmentedControl.frame = CGRectMake(0, 0, 640, 29);

    scrollView.contentSize = CGSizeMake(self.segmentedControl.frame.size.width, self.segmentedControl.frame.size.height -1);
    scrollView.showsHorizontalScrollIndicator = NO;

    self.segmentedControl.selectedSegmentIndex = 0;

    [scrollView addSubview:self.segmentedControl];
    [self.view addSubview:scrollView];

    [self fillJournals];

    // Do any additional setup after loading the view, typically from a nib.
}

您必须设置 的内容大小UIScrollView，否则它不会滚动。

myScrollView.contentSize = mySegmentedControl.frame.size;
