以下是我使用断点获得的错误。

if（[[segue identifier] isEqualToString：@“ShowDetails”]）{         DetailViewController * detailviewcontroller = [segue destinationViewController];

    NSIndexPath *myIndexPath = [self.tableView indexPathForSelectedRow];

    int row = [myIndexPath row];
    detailviewcontroller.DetailModal = @[_Title[row], _Description[row]]; <-- its on this line of code right here.

表示无法识别的选择器发送到实例0x17e6a180 有什么帮助吗？

Answer 1

添加异常断点，然后运行该项目。在大多数情况下，异常断点将停在导致问题的代码行。

您也可以从Debug＆gt;执行此操作。断点＆gt;创建异常断点...

Answer 2

使用NSZombieEnabled = YES;

这可能会为您提供准确的错误报告
