启动崩溃 iOS 应用程序

Question

我正在制作一个应用程序，它使用 GCM、后台任务和钥匙串来保存用户的信息。我通过将我们的设备 UDID 添加到苹果开发者帐户，使用我的开发认证发布了一个版本。但是几天后，我收到用户的反馈，每次启动都会崩溃。我查看代码但找不到这些错误。我得到了这些日志：

请帮我解决这个问题。谢谢你们。我经常撤销并创建新的证书和配置文件，并使用它进行编程。还好吗？

Answer 1

我知道你有一个解决方法，但我更愿意解释为什么会发生这种情况

您的项目需要一个授权文件，并启用 APNS 进行开发或分发。 Apple Doc

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>aps-environment</key>
    <string>development</string>
</dic>

也许你的文件是这样的，但指向分发，所以使用开发会导致它崩溃

希望对你有帮助

虽然堆栈不是很清楚，但它会将您的崩溃范围缩小到几件事。

1. 您的证书似乎无效 - 请转到 Keychain Access 并检查您是否拥有有效的证书以及密钥对是否附加到它。

2. 您的配置文件无效。访问 developer.apple.com 并确保您使用的配置文件有效。

3. Facebook 应用程序权限因某种原因被撤销。请检查您的 Facebook 应用程序并确保一切正常。
