图片无限轮播

YLLoopScrollView

无限轮播(支持纵向和横向轮播), 可以是图片, 可以是任意的自定义view

---

支持pod : pod 'YLLoopScrollView'

使用教程:

---

1.导入头文件

#import "YLLoopScrollView.h"

2.调用类方法构造实例对象

    // 传入轮播的时间(0 代表不启用定时器),需要轮播的自定义view,和需要重新赋值的model
    YLLoopScrollView *scrollView = [YLLoopScrollView loopScrollViewWithTimer:2 customView:^NSDictionary *{
        return @{@"YLCustomView" : @"model"};
    }];

3.设置回调block

    scrollView.clickedBlock = ^(YLLoopScrollView *loopScrollView, NSInteger index) {
        // 点击回调
        NSLog(@"index : %d", index);
    };
        
    scrollView.didScrollBlock = ^(YLLoopScrollView *loopScrollView, UIScrollView *scrollView) {
        // 滚动过程中回调
    };
    
    scrollView.willEndScrollBlock = ^(YLLoopScrollView *loopScrollView, UIScrollView *scrollView) {
        // 滚动结束,将要更新数据时回调
    };

    scrollView.didEndScrollBlock = ^(YLLoopScrollView *loopScrollView, UIScrollView *scrollView) {
        // 滚动结束回调
    };

4.设置数据源

    // arr里存放的是自定义view的model
    scrollView.dataSourceArr = arr;

5.设置frame

    scrollView.frame = CGRectMake(0, 0, self.view.frame.size.width, 150);

6.添加到父视图

    [self.view addSubview:scrollView];

so easy ~~~ (具体使用方法请看demo)

最简单的应用

    NSArray *arr = @[[UIImage imageNamed:@"1.jpg"],
                     [UIImage imageNamed:@"2.jpg"],
                     [UIImage imageNamed:@"3.jpg"],
                     [UIImage imageNamed:@"4.jpg"]];
    YLLoopScrollView *scrollView = [YLLoopScrollView loopScrollViewWithTimer:2 customView:^NSDictionary *{
        return @{@"UIImageView" : @"image"};
    }];
    scrollView.dataSourceArr = arr;
    scrollView.clickedBlock = ^(YLLoopScrollView *loopScrollView, NSInteger index) {
        // todo
    };
    scrollView.frame = CGRectMake(0, 0, self.view.frame.size.width, 100);
    [self.view addSubview:scrollView];
