ios - 在没有 UIScrollView 的情况下使用 UIPageControl

Question

我目前正在使用滑动手势在 View Controller 之间切换，我想知道我是否可以在不使用 uiscrollview 的情况下在每个 View Controller 上实现一个 uipagecontrol。

下面是我如何从一个 View Controller 转到另一个 View Controller :

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    self.title = @"Home";

    UIBarButtonItem *settingsButton = [[UIBarButtonItem alloc] initWithTitle:@"\u2699" style:UIBarButtonItemStyleBordered target:self action:@selector(settingsButtonPressed:)];
    [settingsButton setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIFont boldSystemFontOfSize:24], UITextAttributeFont,nil] forState:UIControlStateNormal];
    self.navigationItem.leftBarButtonItem = settingsButton;

    UIBarButtonItem *systemAction = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:@selector(showMenu)];
    self.navigationItem.rightBarButtonItem = systemAction;

    UISwipeGestureRecognizer *swipeRecognizer = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swipeLeft:)];
    swipeRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
    [self.view addGestureRecognizer:swipeRecognizer];
}

- (IBAction)swipeLeft:(UIGestureRecognizer *)sender
{
    HomeTwo *homeTwo = [[HomeTwo alloc]initWithNibName:@"HomeTwo" bundle:nil];
    homeTwo.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
    [self.navigationController pushViewController:homeTwo animated:YES];
}

UIPageControl 只是一个 View ，因此您当然可以向每个 View Controller View 添加一个 View ，然后将当前页面设置为适当的值。
