Swift / 菜单(视图)导致随机"Command failed due to signal: Segmentation fault: 11"

Question

我有一个Menu.xib，里面有5个UI按钮。我在ViewController中通过按钮IBAction调用此视图。当我尝试运行代码时，编译器会随机抛出：

分段故障：11

当我对我的代码或其中的随机部分进行注释时，比如：menuView.locationBtn.addTarget(self, action: #selector(HomeVC.goLocation), forControlEvents: .TouchUpInside)，代码可能工作，也可能不工作。随机我有一段时间出现了这个错误，找不到问题所在。

@IBAction func menuBtn(sender: AnyObject) {
    let menuView = (NSBundle.mainBundle().loadNibNamed("Menu", owner: self, options: nil).last) as! Menu
    menuView.frame = CGRectMake(0, self.view.bounds.size.height, self.view.bounds.size.width, 100)
    menuView.homeBtn.addTarget(self, action: #selector(HomeVC.goHome), forControlEvents: .TouchUpInside)
    menuView.bookmarkBtn.addTarget(self, action: #selector(HomeVC.goBookmark), forControlEvents: .TouchUpInside)
    menuView.locationBtn.addTarget(self, action: #selector(HomeVC.goLocation), forControlEvents: .TouchUpInside)
    menuView.photoBtn.addTarget(self, action: #selector(HomeVC.goPhoto), forControlEvents: .TouchUpInside)
    menuView.friendsBtn.addTarget(self, action: #selector(HomeVC.goFriends), forControlEvents: .TouchUpInside)
    menuView.settingsBtn.addTarget(self, action: #selector(HomeVC.goSettings), forControlEvents: .TouchUpInside)
    self.view.addSubview(menuView)
    UIView.animateWithDuration(0.6, delay: 0, usingSpringWithDamping: 0.5, initialSpringVelocity: 0.8, options: .CurveEaseInOut, animations: { () -> Void in
        var newMenuFrame = menuView.frame
        newMenuFrame.origin.y = self.view.bounds.size.height - 63
        menuView.frame = newMenuFrame
        self.view.layoutIfNeeded()
    }) { (success) -> Void in
        let gestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(HomeVC.hideOnTap(_:)))
        gestureRecognizer.numberOfTapsRequired = 1
        gestureRecognizer.delegate = self
        gestureRecognizer.cancelsTouchesInView = false
        self.view.addGestureRecognizer(gestureRecognizer)
    }
}
func goHome() {
    print("home")
}

func goBookmark() {
    print("bookmark")
}
func goLocation() {
    print("location")
}
func goPhoto() {
    print("photo")
}
func goFriends() {
    print("friends")
}
func goSettings() {
    print("settings")
}
func hideOnTap(recognizer: UITapGestureRecognizer) {
    self.view.viewWithTag(5)?.removeFromSuperview()
}

当我取消对整个代码的注释时，一切都很好。我在其他项目中经常做这样的事情，没有任何问题。。。非常感谢您的帮助。。。

Answer 1

我用"pod update"完全解决了这个问题。我会留下来，以防有人遇到同样的问题。

这让我想到了下一个问题。我的桥接头不再工作了。我不得不用CMD+ALT+SHIFT+K清理项目（用ALT清理非常重要，通常的清理没有效果！），然后再次运行pod安装。现在一切都恢复正常了。
