Question

我想在自定义单元格中添加一个按钮。我添加它programaticaly和它的工作正常，当我在IB中添加它时，应用程序崩溃。

可能是什么问题？

感谢你的回答。

我的代码： `

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [button addTarget:self 
               action:@selector(goToGeoloc)
     forControlEvents:UIControlEventTouchDown];
    [button setTitle:@"Show View" forState:UIControlStateNormal];
    button.frame = CGRectMake(218.0, 8.0, 45.0, 45.0);
    [cell addSubview:button];

`崩溃日志：
