主线程使用

断言（NSThread.isMainThread（））

。但问题依然存在。我无法解释原因，但将“performSegue”调用推迟到下一次运行循环可以解决此问题。如果这样做，则会使滚动表视图变得更加困难，因为单元格内的滑动可能无法识别。你是对的，我也有同样的问题，我的单元格selectionType为。无，因此发生了延迟，因此，我尝试调用perform seguen“DispatchQueue.main.async”，它成功了，然后我尝试了您的解决方案，现在segue立即出现。selectionType为时出错。无

dispatch_async(dispatch_get_main_queue(),{
    self.performSegue(withIdentifier:mysegueIdentifier,sender: self)
})

DispatchQueue.main.async {
    self.performSegue(withIdentifier: mysegueIdentifier,sender: self)
}

dispatch_async(dispatch_get_main_queue(),{
     self.performSegueWithIdentifier(mysegueIdentifier, sender:self)
})

       let myStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
        let modalViewController = myStoryboard.instantiateViewControllerWithIdentifier("myModalViewController") as! myModalViewController
        modalViewController.modalTransitionStyle = UIModalTransitionStyle.CoverVertical
        let navController = UINavigationController(rootViewController: accountManager)
        dispatch_async(dispatch_get_main_queue(),{
            self.presentViewController(navController, animated: true, completion: nil)
        })

DispatchQueue.main.async {
    self.performSegue(withIdentifier: "theIdentifier", sender: theSender)
}

override func setSelected(_ selected: Bool, animated: Bool) {
    super.setSelected(false, animated: false)
}

import UIKit

class ABCViewController: UIViewController {

  // ... Other useful methods like overriding deinit and didReceiveMemoryWarning

  // Performs a segue on the main thread to ensure it will 
  // transition once a UI-slot is available
  func performSegueOnMainThread(with identifier: String, sender: Any?) {
    DispatchQueue.main.async {
      self.performSegue(with: identifier, sender: sender)
    }
  }
}

myViewController.performSegueOnMainThread(with: "ShowDetailsSegue", sender: self)
