在swift中访问cellFoRrowAtIndexpath之外的tableview单元格时发生致命错误
在我的tableview中，我有3个单元格。在我的第一个手机里，有一个pagerview可以显示照片的数量。当我试图访问cellFoRrowAtIndexpath外侧的单元格，并在那里重新加载pagerview时，我遇到了致命错误。当我试图访问时，我得到的单元格为零。 我的代码是：-在swift中访问cellFoRrowAtIndexpath之外的tableview单元格时发生致命错误,swift,tableview,Swift,Tableview,在我的tableview中，我有3个单元格。在我的第一个手机里，有一个pagerview可以显示照片的数量。当我试图访问cellFoRrowAtIndexpath外侧的单元格，并在那里重新加载pagerview时，我遇到了致命错误。当我试图访问时，我得到的单元格为零。 我的代码是：- class UserDetailTableViewController: UIViewController, UITableViewDelegate, UITableViewDataSource{
