SDCycleScrollView 有好几种初始化的样式，在此列举一些平常日用的样式
1.初始化一些基本属性
UIScrollView *demoContainerView = [[UIScrollView alloc] initWithFrame:self.view.frame];
demoContainerView.contentSize = CGSizeMake(self.view.frame.size.width, 1200);
[self.view addSubview:demoContainerView];
self.title = @"轮播Demo";
// 情景一：采用本地图片实现
NSArray *imageNames = @[@"h1.jpg",
@"h2.jpg",
@"h3.jpg",
@"h4.jpg",
@"h7" // 本地图片请填写全名
];
// 情景二：采用网络图片实现
NSArray *imagesURLStrings = @[
@"https://ss2.baidu.com/-vo3dSag_xI4khGko9WTAnF6hhy/super/whfpf%3D425%2C260%2C50/sign=a4b3d7085dee3d6d2293d48b252b5910/0e2442a7d933c89524cd5cd4d51373f0830200ea.jpg",
@"https://ss0.baidu.com/-Po3dSag_xI4khGko9WTAnF6hhy/super/whfpf%3D425%2C260%2C50/sign=a41eb338dd33c895a62bcb3bb72e47c2/5fdf8db1cb134954a2192ccb524e9258d1094a1e.jpg",
@"http://c.hiphotos.baidu.com/image/w%3D400/sign=c2318ff84334970a4773112fa5c8d1c0/b7fd5266d0160924c1fae5ccd60735fae7cd340d.jpg"
];
// 情景三：图片配文字
NSArray *titles = @[@"新建交流QQ群：185534916 ",
@"感谢您的支持，如果下载的",
@"如果代码在使用过程中出现问题",
@"您可以发邮件到gsdios@126.com"
];
CGFloat w = self.view.bounds.size.width;
2.初始化轮播控件的方法
1.本地加载
// 本地加载 --- 创建不带标题的图片轮播器
SDCycleScrollView *cycleScrollView = [SDCycleScrollView cycleScrollViewWithFrame:CGRectMake(0, 64, w, 180) shouldInfiniteLoop:YES imageNamesGroup:imageNames];
cycleScrollView.delegate = self;
cycleScrollView.pageControlStyle = SDCycleScrollViewPageContolStyleAnimated;
[demoContainerView addSubview:cycleScrollView];
cycleScrollView.scrollDirection = UICollectionViewScrollDirectionVertical;
2.网络加载 --- 创建带标题的图片轮播器
SDCycleScrollView *cycleScrollView2 = [SDCycleScrollView cycleScrollViewWithFrame:CGRectMake(0, 280, w, 180) 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;
});
3.网络加载 --- 创建自定义图片的pageControlDot的图片轮播器
// 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, 500, w, 180) delegate:self placeholderImage:[UIImage imageNamed:@"placeholder"]];
cycleScrollView3.currentPageDotImage = [UIImage imageNamed:@"pageControlCurrentDot"];
cycleScrollView3.pageDotImage = [UIImage imageNamed:@"pageControlDot"];
cycleScrollView3.imageURLStringsGroup = imagesURLStrings;
[demoContainerView addSubview:cycleScrollView3];
4.创建只上下滚动展示文字的轮播器
// 网络加载 --- 创建只上下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:[UIImage imageNamed:@"h1.jpg"]];
cycleScrollView4.scrollDirection = UICollectionViewScrollDirectionVertical;
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 -- demo轮播图4"];
[titlesArray addObjectsFromArray:titles];
cycleScrollView4.titlesGroup = [titlesArray copy];
[demoContainerView addSubview:cycleScrollView4];
3.接下来就是点击的delegate方法了
- (void)cycleScrollView:(SDCycleScrollView *)cycleScrollView didSelectItemAtIndex:(NSInteger)index
{
NSLog(@"---点击了第%ld张图片", (long)index);
if (cycleScrollView.tag ==1) {
NSLog(@"cycleScrollView.tag =1");
}else{
NSLog(@"cycleScrollView.tag =2**3");
}
ActionRabiosModel *model = actIDs[index];
ActionDetailViewController *vc = [[ActionDetailViewController alloc]initWithNibName:@"ActionDetailViewController" bundle:MAINBUNDLE];
vc.actionId = [model.act_id intValue];
vc.hidesBottomBarWhenPushed = YES;
[self.navigationController pushViewController:vc animated:YES];
}
