一、DZNEmptyDataSet使用
// 偏移量 - 向上偏移64像素
func verticalOffset(forEmptyDataSet scrollView: UIScrollView) -> CGFloat {
return -64.0
}
// 显示图片
func image(forEmptyDataSet scrollView: UIScrollView) -> UIImage? {
return UIImage(named: "blank")
}
// 允许刷新
func emptyDataSetShouldAllowScroll(_ scrollView: UIScrollView) -> Bool {
return true
}
// 文字显示
func title(forEmptyDataSet scrollView: UIScrollView) -> NSAttributedString? {
let title = "暂时没有数据"
let attributes = [NSFontAttributeName: UIFont.boldSystemFont(ofSize: 15),
NSForegroundColorAttributeName: UIColor(hexColor: "c5c5c5")]
return NSAttributedString(string: title, attributes: attributes)
}
// 点击重试
func buttonTitle(forEmptyDataSet scrollView: UIScrollView, for state: UIControlState) -> NSAttributedString? {
let title = "暂时没有数据，请点击重试哦~"
let font = UIFont.systemFont(ofSize: 15)
let attString = NSMutableAttributedString(string: title)
attString.addAttribute(NSFontAttributeName, value: font, range: NSMakeRange(0, title.characters.count))
attString.addAttribute(NSForegroundColorAttributeName, value: UIColor(hexColor: "c5c5c5"), range: NSMakeRange(0, title.characters.count))
attString.addAttribute(NSForegroundColorAttributeName, value: UIColor(hexColor: "0093fa"), range: NSMakeRange(8, 4))
return attString
}
// 自定义视图
func customView(forEmptyDataSet scrollView: UIScrollView) -> UIView? {
// 当数据还没有加载完成的时候，显示空
return isLoadDataFinish ? PlaceHolderView() : nil
}
