swift – 类型’Int’不符合协议’BooleanType’

override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    if indexPath.row && currentRow?.row == 5 {
        return  300
    }
    return 70

我得到的错误是：

Type ‘Int’ does not conform to protocol ‘BooleanType’

if indexPath.row == currentRow?.row  && currentRow == 5 {

要么：

if indexPath.row == 5  && currentRow?.row == 5 {

如果要检查indexPath是否为nil,请检查indexPath是否为0

if indexPath.row != 0 && currentRow?.row == 5 {
