ios - Swift/菜单( View )随机导致 "Command failed due to signal: Segmentation fault: 11"

Question

我有一个带有 5 个 UIButtons 的 Menu.xib。我在 ViewController 中的按钮 IBAction 上调用此 View 。当我尝试运行代码时，编译器随机抛出:

Segmentation fault: 11

当我评论我的代码或其中的随机部分时，例如: menuView.locationBtn.addTarget(self, action: #selector(HomeVC.goLocation), forControlEvents: .TouchUpInside) 代码可能会工作或也许不会。随机地。我已经遇到这个错误有一段时间了，但找不到问题所在。

@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()
}

当我取消整个代码的注释时，一切正常。我在其他项目中经常做过类似的事情，没有任何问题...非常感谢帮助...

Answer 1

我通过“pod update”完全解决了这个问题。我会留下它，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 header 不再工作。我必须使用 CMD + ALT + SHIFT + K 清理项目(使用 ALT 清理它非常重要，通常的清理没有效果!)并再次运行 pod install。现在一切都恢复正常了。
