example - uitableviewcell expand on click in ios swift




iOS:'MyViewController'가 'UITableViewDataSource'프로토콜을 준수하지 않습니다. (3)

전체 오류 메시지를 살펴 봐야합니다. 이 특정 메시지에는 누락 된 메서드에 대한 추가 정보가 포함되어 있습니다.

Type 'MyViewController' does not conform to protocol 'UITableViewDataSource'
Protocol requires function 'tableView(_:numberOfRowsInSection:)' with type '(UITableView, numberOfRowsInSection: Int) -> Int'
Candidate has non-matching type '(UITableView!, numberOfRowsInSection: Int) -> Int'

그래서 ... numberOfRowsInSection은 선택적 UITableView를 취하고 필요한 UITableView를 가져와야합니다 (이것은 6에서 6.1 사이의 변경이며 모든 UITableView 대리자 및 데이터 소스 메서드는 이제 필요한 tableView 및 indexPath 값을가집니다)

  • 나는 IOS swift 개발에 IOS swift . 이전 Xcode 6 beta 에서 작업하곤했습니다.

  • Xcode 6.0.1 을 다운로드 Xcode 6.0.1 작동하지 않습니다 Xcode Version: 6.0.1

  • 나는 " MyViewController '가 예제를 실행하려고 할 때' UITableViewDataSource '프로토콜을 확인하지 못하고 있습니다.

누군가 나를 도울 수 있습니까? 이 사이트에서 다른 문제를 겪고 " UITableViewDataSource "에 필요한 모든 기능을 추가했습니다.

나를 위해, 상속 된 클래스 목록에서 UITableViewDataSource 제거 문제가 해결되었습니다.


class ROTableView: UITableView, UITableViewDelegate {

    func tableView(tableView:UITableView!, numberOfRowsInSection section:Int) -> Int {
        return 10
    }

    func tableView(tableView:UITableView!, cellForRowAtIndexPath indexPath:NSIndexPath!) -> UITableViewCell! {
        let cell: UITableViewCell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: "MyTestCell")

//        cell.text = "Row #\(indexPath.row)"
//        cell.detailTextLabel.text = "Subtitle #\(indexPath.row)"

        return cell
    }

    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

    }
}

위의 코드를 참조하십시오 UITableView 대한 하위 클래스를 만들 때 오류가 발생하지 않습니다.
