无法调用非函数类型的值：UITableView

Question

I've a Swift class that extends from UITableViewController . It has this function

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {...}

There's need that, I need to call this function programatically at one place and when I write

self.tableView(tableView, cellForRowAt: 1)

• I get, Cannot call value of non-function type 'UITableView!'

How can I call this function programatically?

Answer 1

You don't need to (you're not supposed to) call that delegate/datasource method directly. UITableView has a func for that:

tableView.cellForRow(at: indexPath)

Just create the index path based on your row, like:

let indexPath = IndexPath(row: 1, section: 0)

Answer 2

cellForRowAt takes an IndexPath , not an Int :

func someFunc(indexPath: IndexPath) {
    let cell = tableView(tableView, cellForRowAt: indexPath)
    print(cell)
}
