HDEmptyView
一个Swift语言封装的EmptyView显示库,可作用于WKWebView、UITableView、UICollectionView
示例
- WKWebView

- UITableView

- UICollectionView

要求
- iOS 9.0+
- Xcode 9.0+
- Swift4 (HDEmptyView 4.x)
使用方法
1、创建 HDEmptyView 界面显示对象
//创建方式一:Block回调
let emptyV:HDEmptyView = HDEmptyView.emptyActionViewWithImageStr(imageStr: "net_error_tip", titleStr: "暂无数据,点击重新加载", detailStr: "", btnTitleStr: "点击刷新") {
print("点击刷新")
weakSelf?.reloadDataWithCount(count: 4)
}
//创建方式二:target/action
let emptyV:HDEmptyView = HDEmptyView.emptyActionViewWithImageStr(imageStr: "net_error_tip", titleStr: "暂无数据,点击重新加载", detailStr: "", btnTitleStr: "点击刷新", target: self, action: #selector(reloadBtnAction)) as! HDEmptyView
2、设置显示参数属性
emptyV.titleLabTextColor = UIColor.red
emptyV.actionBtnFont = UIFont.systemFont(ofSize: 19)
emptyV.contentViewOffset = -50
emptyV.actionBtnBackGroundColor = .white
emptyV.actionBtnBorderWidth = 0.7
emptyV.actionBtnBorderColor = UIColor.gray
emptyV.actionBtnCornerRadius = 10
3、赋值给当前显示对象的ly_emptyView
webView.scrollView.ly_emptyView = emptyV
tableView.ly_emptyView = emptyV
collectionView.ly_emptyView = emptyV
//设置点击空白区域是否有刷新操作
self.webView.scrollView.ly_emptyView?.tapContentViewBlock = {
//weakSelf!.loadingURL(urltring: "http://news.baidu.com/")
}
4、自定义空数据界面显示
//自定义空数据界面显示
func setupMyEmptyView() {
let emptyView: MyEmptyView = Bundle.main.loadNibNamed("MyEmptyView", owner: self, options: nil)?.last as! MyEmptyView
emptyView.reloadBtn.addTarget(self, action: #selector(reloadBtnAction(_:)), for: UIControlEvents.touchUpInside)
emptyView.frame = view.bounds
//空数据界面显示
let emptyV:HDEmptyView = HDEmptyView.emptyViewWithCustomView(customView: emptyView) as! HDEmptyView
tableView.ly_emptyView = emptyV
tableView.ly_emptyView?.tapContentViewBlock = {
print("点击界面空白区域")
}
tableView.ly_showEmptyView()
}
注意事项:是否自动显隐EmptyView的参数 autoShowEmptyView 默认设置是true,列表视图会根据界面cell的count数量自动显隐空界面。当设置成false时只能手动调用 ly_showEmptyView() 和 ly_hideEmptyView() 方法进行显隐操作
