在iOS开发中，我们一定会用的类似欢迎界面的东西。当中须要翻页和以下的提示小圆点。

在iOS的实现中，翻页效果是使用UIScrollView。而UIPageView仅仅是加入以下的提示小圆点而已。

以下我贴出详细实现比較简单：

@property (nonatomic , strong) UIScrollView *adScrollView;
@property (nonatomic , strong) UIPageControl *adPageControl;

@implementation ADView

- (id)initWithFrame:(CGRect)frame andImagePathArr:(NSArray *)pathArr
{
    if (self = [super initWithFrame:frame]) {
 
      
        
        _adScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, frame.size.width, frame.size.height)];
        _adScrollView.pagingEnabled = true;
        _adScrollView.bounces = false;
        _adScrollView.delegate = self;
        _adScrollView.contentSize = CGSizeMake(frame.size.width * pathArr.count, frame.size.height);
       

        [self addSubview:_adScrollView];
        
     
        
        for (int i = 0; i < pathArr.count; i++) {
            UIImageView * adImageView = [[UIImageView alloc] initWithImage:[UIImage imageWithContentsOfFile:pathArr[i]]];
            adImageView.frame = CGRectMake(frame.size.width * i, 0, frame.size.width, frame.size.height);
            [_adScrollView addSubview:adImageView];
        }
        

        
        
        _adPageControl = [[UIPageControl alloc] initWithFrame:CGRectMake(0, CGRectGetMaxY(_adScrollView.frame) - 30, frame.size.width, 30)];
        [_adPageControl addTarget:self action:@selector(pageTurn:) forControlEvents:UIControlEventAllEditingEvents];
        
        _adPageControl.numberOfPages = pathArr.count;
        _adPageControl.currentPage = 0;
        [self addSubview:_adPageControl];
        
        
        
    }
    return self;
}
- (void) pageTurn:(UIPageControl *)sender
{
    CGSize viewSize = _adScrollView.frame.size;
    CGRect rect = CGRectMake(sender.currentPage * viewSize.width, 0, viewSize.width, viewSize.height);
    [_adScrollView scrollRectToVisible:rect animated:YES];
    
}

- (void) scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
    CGPoint offset = scrollView.contentOffset;
    CGRect bounds = scrollView.frame;
    _adPageControl.currentPage = offset.x / bounds.size.width;
    
    
    
}
