Question

当我使用XCode运行它时，应用程序运行良好。我尝试了iOS 7，iOS 8设备和模拟器。我将应用程序发布到App Store中，并在更新后在启动屏幕上崩溃。我还尝试将应用程序上传到预发布的TestFlight应用程序中，它也在启动屏幕上崩溃。你能帮忙调试吗？

方法代码：

required init(coder aDecoder: NSCoder)  {
    let path = NSBundle.mainBundle().pathForResource("menu_items", ofType: "plist")
    self.menuItems = NSArray(contentsOfFile: path!) as [NSDictionary]

我发现如果我在文件读取后添加睡眠它可以正常工作。那太奇怪了。

没有睡觉：

override func viewDidLoad() {
    super.viewDidLoad()
    if let path = NSBundle.mainBundle().pathForResource("menu_items", ofType: "plist") {
        self.menuItems = NSArray(contentsOfFile: path) as? [NSDictionary]
        NSLog("Path Exists");
        if let mi = self.menuItems {
            NSLog("Content Exists");
            NSLog("%@",mi)
        }
    }
    self.menuTableView.reloadData()
}

输出

Path Exists

self.menuItems是零

睡觉：

 override func viewDidLoad() {
    super.viewDidLoad()
    if let path = NSBundle.mainBundle().pathForResource("menu_items", ofType: "plist") {
        self.menuItems = NSArray(contentsOfFile: path) as? [NSDictionary]
        NSLog("Path Exists");
        if let mi = self.menuItems {
            NSLog("Content Exists");
            NSLog("%@",mi)
        }
        sleep(10)
        if let mi = self.menuItems {
            NSLog("Content Exists 2");
            NSLog("%@",mi)
        }
    }
    self.menuTableView.reloadData()
}

输出：

Path Exists
Content Exists
%here is data of my array%
Content Exists 2
%here is data of my array%

self.menuItems不是零，睡觉之前和之后！ O_O

Answer 1

我想问题在于构建设置，如果在项目中使用swift，似乎应该将构建设置"Embedded Content Contains Swift Code"中的标志从NO切换到YES。

我曾试图谷歌更多关于这个标志的信息，我在苹果开发者门户网站上找到了一些信息：

构建不包含Swift源文件的应用程序时但嵌入其他内容（如框架，XPC服务，应用程序扩展，等等）确实包含Swift代码，你必须设置构建设置嵌入式内容包含Swift代码（EMBEDDED_CONTENT_CONTAINS_SWIFT）。这样Swift库就会这样被包括在申请中。（17757566）

此外，我发现这篇文章看起来像你的问题：breefield.com/essays/critical-app-review

Answer 2

我是如何解决这个问题的：

NSArray(contentsOfFile: path)向下转型对归档应用中的swift数组很奇怪。有时候它会正常下载，有时会为同一个plist文件返回nill（文件中没有变化）。我将所有使用文件的[NSDictionary]替换为NSArray?，现在效果很好。

此问题仅针对应用商店应用（.ipa）存档。如果我在模拟器或设备上运行它，它也适用于swift数组。

感谢@fluidsonic提供关于施法的建议。
