在swift中以编程方式调用segue的sigabrt错误 [英] sigabrt error calling segue programatically in swift

问题描述

我是iOS开发新手，目前正在尝试在选择 UITableViewController 中的单元格后以编程方式调用segue。虽然我已经在故事板中创建了segue并为其分配了一个标识符，但我仍然在重写的 didSelectRowAtIndexPath <中的 performSegueWithIdentifier 方法调用中收到sigabrt错误/ code>方法。任何帮助将不胜感激。

I am new to iOS development and am currently attempting to call a segue programmatically after a cell in a UITableViewController is selected. Although I already created the segue in my storyboard and assigned it an identifier, I still receive a sigabrt error at the performSegueWithIdentifier method call within an overridden didSelectRowAtIndexPath method. Any help would be greatly appreciated.

override func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) 
{
    self.performSegueWithIdentifier("toExerciseInfo", sender: self)
}

当你从故事板到视图控制器的连接不良时，会出现这个问题。在我的情况下，我将一个按钮连接到插座，然后删除插座，留下悬空连接。通过ctrl +单击故事板中的视图，可视地检查列出的连接，然后删除不再有效的连接，我能够相当容易地修复它。我确定还有其他方法可以解决这个错误，但这对我有用。

This is a problem that can occur when you have a bad connection from your storyboard to the view controller. In my case, I'd connected a button to an outlet, then deleted the outlet, leaving a dangling connection. I was able to fix it fairly easily by ctrl+clicking the view in the storyboard, visually inspecting the connections listed, and then deleting the one that was no longer valid. I'm sure there are other ways to fix the error, but that's what worked for me.
