    可实现自动循环轮播 slider 效果

    源码和使用 demo 都在这里: https://github.com/liaojinxing/LJAutoScrollView

    欢迎使用,如有问题也请不吝赐教。

    LJAutoScrollView

    LJAutoScrollView class provides an endlessly circulate scroll view. It allows auto scrolling infinitely in the horizontal direction.

    • It offers an encapsulation of UICollectionView to support reuse features.

    • Use NSTimer for auto scrolling.

    • The implement of infinite scroll is inspired by this page:Circular Infinite UIScrollView

    Comparison

    Compared to other implmentation, LJAutoScrollView is more stable and easier to use:
    - Some implementation like GBInfiniteScrollView is subclass from UIScrollView, while LJAutoScrollView uses UICollectionView, it's more stable on reuse feature and gesture recognization.

    • LJAutoScrollView integrates UIPageControl as well. You need not to handle the page change yourself.

    • The infinite circulate scroll feature implementation is more elegant and robust than SDCycleScrollView.

    • It's easier to use. The usage is described below.

    Installation

    Grab the source file into your project.

    Or use cocoapods. Here is an example of your podfile:

    pod 'LJAutoScrollView'
    

    Usage

    • LJAutoScrollView is a subclass of UIView. Just take it as UIView when initialization.
    self.autoScrollView = [[LJAutoScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, kAutoScrollViewHeight)];
    
    self.autoScrollView.delegate = self;
    
    • Configure it as you like.
    self.autoScrollView.itemSize = CGSizeMake(self.view.frame.size.width, kAutoScrollViewHeight);
    
    self.autoScrollView.scrollInterval = 3.0f;
    
    • Don't forget to implement the delegate methods.

    Check the demo project for more details.
