我有一个快速的应用程序被App Review拒绝，因为它在发布时崩溃了。
我象征着崩溃报告，发现了这个：
...
OS Version: iOS 9.0.2 (13A452)
...
Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Subtype: KERN_INVALID_ADDRESS at 0x0000000000000048
Triggered by Thread: 0
...
Thread 0 name: Dispatch queue: com.apple.main-thread
Thread 0 Crashed:
0 myappname 0x00000001000d88e8 specialized NetworkDiagramViewController.viewDidLoad() -> () (NetworkDiagramViewController.swift:117)

2 UIKit 0x000000018b7af610 -[UIViewController loadViewIfRequired] + 1124
...
以下是NetworkDiagramViewController.swift的相关部分：
...
11: class NetworkDiagramViewController: UIViewController {
12:
13: @IBOutlet weak var serverLabel: UILabel!
...
29: override func viewDidLoad() {
30: super.viewDidLoad()
31: updateCloudViews()
32: }
...
116: private func updateCloudViews() {
117: serverLabel.text = ServerSettings.host ?? " "
118: }
...
我已经仔细检查过serverLabel插座是否正确连接在故事板中。这种崩溃永远不会发生在我的任何测试设备或模拟器中。
