以下是swift2中的代码2.could大家帮帮我

private func getIndexInTheLastSection(indexPath: NSIndexPath) -> Int? {
        let index = indexPath.indexAtPosition(indexPath.length - 1)

            return nil
        }
        return index
    }

Answer 1

对于 isEqual 错误 URL 使用 == 而不是 isEqual 进行比较。

if urlRequest.URL! == strongSelf.request?.urlRequest?.URL {

错误Argument labels '(atPosition:)'

indexPath.index(atPosition: (indexPath as NSIndexPath).length - 1)

swift 3 相当于 indexAtPosition，urlRequest.url!.isEqual

swift 3 equivalent for indexAtPosition, urlRequest.url!.isEqual

xcode
