EXC_SOFTWARE / UNCAUGHT_NS_EXCEPTION

问题描述 投票:3回答:1

我在生活应用程序中发生了崩溃,我无法在我的设备上重现。我无法弄清楚是什么原因造成的。我研究了崩溃报告,但似乎无法理解造成这种情况的原因。

35 XXX main (XXXViewController.swift:14)
36 libdyld.dylib
start + 17844

第35行(仅提及我编写的代码)是XXXViewController类定义行:

class XXXViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
...
}

这个ViewController调用一个观察者,这似乎是个问题。我确保删除在deinit函数中使用它们的ViewControllers中的所有观察者。

deinit {
    NSNotificationCenter.defaultCenter().removeObserver(self)
}

有没有人知道还有什么可能出错?

更新:我像这样注册观察者ini init()(我应该使用viewDidLoad吗?):

NSNotificationCenter.defaultCenter().addObserver(self, selector:#selector(YViewController.dataUpdate(_:)), name: "DataChanged", object: nil)

并发布这样的通知:

NSNotificationCenter.defaultCenter().postNotificationName("DataChanged", object: self, userInfo: nil)

YViewController dataUpdate如下:

func dataUpdate(notification: NSNotification) {
    //Some stuff is done
}

我现在使用swift 2.0,崩溃发生在iOS版本10.0.1-10.1.1上

以防任何人降落在这里。问题是我覆盖了GLKViewController的基本视图,而不是将新视图添加为子视图。当我切换到Crashlytics时,这变得很容易清楚,Crashlytics有关于崩溃的更多信息。
