照片浏览器

PhotoBrowser是一款轻量级的图片浏览器，类似于微信、微博的图片浏览器。

现在，名为 SlidingPhoto 的纯 Swift 版本已经可用。

特征

出席和解散动画和手势
GIF 支持
显示长图

看起来怎么样？

用法

与UITableView API 一样，我们有DataSource一个用于加载数据和处理操作Delegate
告诉PhotoBrowser您想要通过符合协议PBViewControllerDataSource呈现多少页并实现numberOfPagesInViewController:选择器
可选通过pb_startPage属性设置初始化页面
用于静态图像 - 符合协议PBViewControllerDataSource并实现viewController:imageForPageAtIndex:选择器
用于网络图像 - 符合协议PBViewControllerDataSource并实现viewController:presentImageView:forPageAtIndex:progressHandler选择器
支持动画 - 符合PBViewControllerDataSource协议并实现thumbViewForPageAtIndex:告诉imageView的开始和结束位置
操作回调 - 符合协议PBViewControllerDelegate并实现viewController:didSingleTapedPageAtIndex:presentedImage:或viewController:didLongPressedPageAtIndex:presentedImage:处理单击或长按操作

演示代码

PBViewController *pbViewController = [PBViewController new ];
// Use your own subclass of UIImageView to display.
pbViewController.imageViewClass = PBImageView.class;
pbViewController.pb_dataSource = self;
pbViewController.pb_delegate = self;
pbViewController.pb_startPage = sender.tag;
[ self presentViewController: pbViewController animated: YES completion: nil ];
...
