Swift Struct to dynamically hide and show UITableView Rows by name. This is written in Swift 5.
Includes sample app.
- Cocoapods
- Include TableViewHelper.swift in your project
Instantiate a copy of the class with a reference to the tableView:
helper = TableViewHelper(tableView:tableView)Add all cells that can show to the helper giving each cell a name (multiple cells can have the same name):
helper.addCell(section: 0, cell: tableView.dequeueReusableCellWithIdentifier("S0R0")! as UITableViewCell, name: "S0R0")
helper.addCell(section: 0, cell: tableView.dequeueReusableCellWithIdentifier("S0R1")! as UITableViewCell, name: "S0R1")
helper.addCell(section: 1, cell: tableView.dequeueReusableCellWithIdentifier("S1R0")! as UITableViewCell, name: "S1R0")Reference the helper class for relevant UITableView calls:
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return helper.numberOfSections()
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return helper.numberOfRows(in: section)
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
return helper.cellForRow(at: indexPath)
}Hide or show cells by name (if multiple cells have the same name, then all with that name are shown or hidden):
helper.hideCell("S0R0")
helper.hideCell("S0R1")
helper.showCell("S1R0")init(tableView:UITableView)
func addCell(section:Int, cell:UITableViewCell, name:String, isInitiallyHidden: Bool = false)
func hideInitiallyHiddenCells()
func hideCell(_ name:String)
func showCell(_ name:String)
func cellName(at indexPath:NSIndexPath) -> String?
func indexPathForCell(_ name:String) -> NSIndexPath? // first matching cell
func indexPathsForCell(_ name:String) -> [NSIndexPath]
func visibleCells(_ name:String) -> [UITableViewCell]
func cellIsVisible(_ name:String) -> Bool // // returns true if ALL cells with that name are visible
func numberOfSections() -> Int
func numberOfRows(inSection section: Int) -> Int
func cellForRow(at indexPath: NSIndexPath) -> UITableViewCell
