1.加载本地图片 --- 创建不带标题的图片轮播器

//         --- 轮播时间间隔，默认1.0秒，可自定义

2.网络图片加载 --- 创建带标题的图片轮播器

2.1网络图片加载 --- 创建带标题的图片轮播器

SDCycleScrollView *cycleScrollView2 = [SDCycleScrollView cycleScrollViewWithFrame:CGRectMake(0, 280, self.view.frame.size.width, _demoContainerView.frame.size.height) delegate:self placeholderImage:[UIImage imageNamed:@"placeholder"]];

cycleScrollView2.pageControlAliment = SDCycleScrollViewPageContolAlimentRight;

//cycleScrollView2.titlesGroup = titles;

cycleScrollView2.currentPageDotColor = [UIColor whiteColor]; // 自定义分页控件小圆标颜色

[_demoContainerView addSubview:cycleScrollView2];

//         --- 模拟加载延迟

//dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.3 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

//    cycleScrollView2.imageURLStringsGroup = imagesURLStrings;

//});

//

/*

 block监听点击方式

 cycleScrollView2.clickItemOperationBlock = ^(NSInteger index) {

 NSLog(@">>>>>  %ld", (long)index);

 };

2.2网络加载 --- 创建自定义图片的pageControlDot的图片轮播器

SDCycleScrollView *cycleScrollView3 = [SDCycleScrollView cycleScrollViewWithFrame:CGRectMake(0, 0, self.view.frame.size.width, _demoContainerView.frame.size.height) delegate:self placeholderImage:nil];

cycleScrollView3.imageURLStringsGroup = _imagesURLStrings;

[_demoContainerView addSubview:cycleScrollView3];

2.3网络加载 --- 创建只横向滚动展示文字的轮播器

// 由于模拟器的渲染问题，如果发现轮播时有一条线不必处理，模拟器放大到100%或者真机调试是不会出现那条线的

SDCycleScrollView *cycleScrollView4 = [SDCycleScrollView cycleScrollViewWithFrame:CGRectMake(0, 750, w, 40) delegate:self placeholderImage:nil];

cycleScrollView4.scrollDirection = UICollectionViewScrollDirectionHorizontal;

cycleScrollView4.onlyDisplayText = YES;

NSMutableArray *titlesArray = [NSMutableArray new];

[titlesArray addObject:@"纯文字上下滚动轮播"];

[titlesArray addObject:@"纯文字上下滚动轮播 "];

//[titlesArray addObjectsFromArray:titles];

cycleScrollView4.titlesGroup = [titlesArray copy];

[_demoContainerView addSubview:cycleScrollView4];

#pragma mark - SDCycleScrollViewDelegate

- (void)cycleScrollView:(SDCycleScrollView *)cycleScrollView didSelectItemAtIndex:(NSInteger)index

{

    NSLog(@"---点击了第%ld张图片", (long)index);

    // [self.navigationController pushViewController:[NSClassFromString(@"DemoVCWithXib") new] animated:YES];

}

// 滚动到第几张图回调

- (void)cycleScrollView:(SDCycleScrollView *)cycleScrollView didScrollToIndex:(NSInteger)index

{

    // NSLog(@">>>>>> 滚动到第%ld张图", (long)index);
