iOS用第三方类库实现轮播图
在github上面有很多的第三方类库,大大节约了大家的开发时间
下载地址:https://github.com/gsdios/SDCycleScrollView
现已支持cocoapods导入:pod 'SDCycleScrollView','~> 1.61'
效果
具体实现代码
#import "ViewController.h" #import "SDCycleScrollView.h" @interface ViewController () <SDCycleScrollViewDelegate> @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor = [UIColor colorWithRed:0.98 green:0.98 blue:0.98 alpha:0.99]; UIImageView *backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"005.jpg"]]; backgroundView.frame = self.view.bounds; [self.view addSubview:backgroundView]; 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; // >>>>>>>>>>>>>>>>>>>>>>>>> demo轮播图1 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> // 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]; // --- 轮播时间间隔,默认1.0秒,可自定义 //cycleScrollView.autoScrollTimeInterval = 4.0; // >>>>>>>>>>>>>>>>>>>>>>>>> demo轮播图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; }); /* block监听点击方式 cycleScrollView2.clickItemOperationBlock = ^(NSInteger index) { NSLog(@">>>>> %ld", (long)index); }; */ // >>>>>>>>>>>>>>>>>>>>>>>>> demo轮播图3 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> // 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]; } #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); } */ @end
