以前写本身项目内部的应用调试工具箱:JXCaptain的时候。须要一个显示数据库的视图,须要有行列表头固定,而且表单内容能够上下左右滑动查看的特性,就像Excel视图同样。整个功能就只有一个ExcelView类,逻辑清晰简单,便于阅读和修改定制需求。git

ExcelView
excel = ExcelView(frame: CGRect.zero) excel.dataSource = self excel.delegate = self view.addSubview(excel) 复制代码
ExcelViewDataSource
代理方法func numberOfRows(in excelView: ExcelView) -> Int { return 50 } func numberOfColumns(in excelView: ExcelView) -> Int { return 10 } func excelView(_ excelView: ExcelView, columnNameAt column: Int) -> String { return "col:\(column)" } func excelView(_ excelView: ExcelView, rowDataAt row: Int) -> [String] { return dataSource[row] } func excelView(_ excelView: ExcelView, rowHeightAt row: Int) -> CGFloat { return 40 } func excelView(_ excelView: ExcelView, columnWidthAt column: Int) -> CGFloat { return 120 } func widthOfLeftHeader(in excelView: ExcelView) -> CGFloat { return 50 } func heightOfTopHeader(in excelView: ExcelView) -> CGFloat { return 40 } 复制代码
ExcelViewDelegate
代理方法func excelView(_ excelView: ExcelView, didTapGridWith content: String) { print("didTapGridWith:\(content)") } func excelView(_ excelView: ExcelView, didTapColumnHeaderWith name: String) { print("didTapColumnHeaderWith:\(name)") } 复制代码
