UIPageControl 也仅仅只是一种预定好的UIView

该UIView的基本样式

如下

唯一值得注意的是该View的 userInteractionEnabled 被设置为NO了 UIView 设置为YES

如果需要添加响应滑动翻页这个就要设置为YES

代码附上

- (void)viewDidLoad {
    [super viewDidLoad];


    UIView *view1 = [[UIView alloc] initWithFrame:self.view.bounds];
    view1.backgroundColor = [UIColor redColor];
    UIView *view2 = [[UIView alloc] initWithFrame:self.view.bounds];
    view2.backgroundColor = [UIColor blueColor];
    UIView *view3 = [[UIView alloc] initWithFrame:self.view.bounds];
    view3.backgroundColor = [UIColor greenColor];

    _views = @[view1,view2,view3];

    self.view.backgroundColor = [UIColor whiteColor];
    _pageControl = [[UIPageControl alloc] initWithFrame:CGRectMake(0, self.view.bounds.size.height-50, self.view.bounds.size.width, 50)];
    _pageControl.backgroundColor = [UIColor grayColor];
    _pageControl.numberOfPages = 3;

    _pageControl.pageIndicatorTintColor = [UIColor blackColor];
    _pageControl.currentPage = 0;
    _pageControl.currentPageIndicatorTintColor = [UIColor redColor];
    _pageControl.userInteractionEnabled = YES;
    [_pageControl addTarget:self action:@selector(changeIndex) forControlEvents:UIControlEventValueChanged];
    [self.view addSubview:view3];
    [self.view addSubview:view2];
    [self.view addSubview:view1];

    [self.view addSubview:_pageControl];
    [self changeIndex];


}

- (void)changeIndex{
    UIView *view = [_views objectAtIndex:_pageControl.currentPage];
    [self.view insertSubview:view belowSubview:_pageControl];
}

that's all

thx

Everything you see on Screen is UIView.
