BlockTableView-Swift

single line UITableView creation in Swift with power of the closures

Usage

Copy & paste BlockTableView.swift into your project.

    let table = BlockTableView (frame: self.view.frame,
        numberOfRowsInSection: { (section) -> Int in
            return dataSource.count
        },
        cellForRowAtIndexPath: { (tableView, indexPath) -> UITableViewCell in
            var cell = UITableViewCell (style: .Default, reuseIdentifier: "Identifer")

            let current = dataSource[indexPath.row]
            cell.textLabel.text = current

            return cell
        },
        didSelectRowAtIndexPath: { (tableView, indexPath) -> () in
            let selected = dataSource[indexPath.row]
            println("\(selected) selected")

            tableView.deselectRowAtIndexPath(indexPath, animated: true)
        }
    )

Initilizers

convenience init(frame: CGRect,
    numberOfRowsInSection   : (section: Int) -> Int,
    cellForRowAtIndexPath   : (tableView: UITableView, indexPath: NSIndexPath) -> UITableViewCell,
    didSelectRowAtIndexPath : (tableView: UITableView, indexPath: NSIndexPath) -> ())

convenience init(frame: CGRect,
    numberOfSections        : Int,
    titleForHeaderInSection : (section: Int) -> String,
    numberOfRowsInSection   : (section: Int) -> Int,
    cellForRowAtIndexPath   : (tableView: UITableView, indexPath: NSIndexPath) -> UITableViewCell,
    didSelectRowAtIndexPath : (tableView: UITableView, indexPath: NSIndexPath) -> ())

convenience init(frame: CGRect,
    registeredCells         : [String: AnyClass],
    numberOfRowsInSection   : (section: Int) -> Int,
    cellForRowAtIndexPath   : (tableView: UITableView, indexPath: NSIndexPath) -> UITableViewCell,
    didSelectRowAtIndexPath : (tableView: UITableView, indexPath: NSIndexPath) -> ())

init(frame: CGRect,
    registeredCells         : [String: AnyClass]?,
    numberOfSections        : Int?,
    titleForHeaderInSection : ((section: Int) -> String)?,
    numberOfRowsInSection   : (section: Int) -> Int,
    cellForRowAtIndexPath   : (tableView: UITableView, indexPath: NSIndexPath) -> UITableViewCell,
    didSelectRowAtIndexPath : (tableView: UITableView, indexPath: NSIndexPath) -> ())

• You can easily add more initilizers with more UITableViewDelegate/UITableViewDataSource methods

Search Bar

Search bar implementation never been easier

func addSearchBar (searchResultTableView tableView: BlockTableView,  didSearch: (String)->())

Just create another BlockTableView for displaying results and implement the filtering or searching function in didSearch, like

    var filtered: [String]! // search result dataSource

    table.addSearchBar(searchResultTableView:
        BlockTableView (frame: self.view.frame,
            numberOfRowsInSection: { (section) -> Int in
                return filtered.count
            },
            cellForRowAtIndexPath: { (tableView, indexPath) -> UITableViewCell in
                var cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell
                cell.textLabel?.text = filtered[indexPath.row]
                return cell
            },
            didSelectRowAtIndexPath: { (tableView, indexPath) -> () in
                return
            }
        ), didSearch: { searchText in
            filtered = filter (dataSource) { $0.rangeOfString(searchText) != nil }
        }
    )
