启动崩溃iOS应用程序
问题描述：
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Apple开发者帐户，发布了使用我的开发认证的版本。但几天后，我收到了用户的反馈，每当启动时都会崩溃。我审查代码，但无法找到这些错误。我得到这个日志：启动崩溃iOS应用程序

请帮我这个。谢谢你们。我经常撤销并创建新的证书和配置文件，并用它来编程。它很好吗？
答
我知道你有一个解决方法，但我更愿意解释为什么发生这种情况
您需要在项目的授权文件，并与开发或分销启用APNS。 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，但指向的分布，所以使用的发展将导致崩溃
希望这有助于

虽然堆栈是不是很清楚，它缩小您的碰撞几件事情。
您的证书似乎并不有效 - 请转到钥匙串访问，并检查是否有一个有效的证书和密钥对连接到它。
您的供应配置文件失效。转到developer.apple.com并确保您使用的配置文件是有效的。
由于某种原因，Facebook应用程序权限被吊销。请检查您的Facebook应用程序并确保一切正常。
编译时出现任何错误？像往常一样，尝试清理该项目：'cmd' +'shift' +'clean'，这有时可以帮助。另外'用于签署可执行文件的身份不再有效.'意味着签名身份有些不正确，可能不是崩溃的原因，但是您应该尝试修复此问题。 – LinusGeffarth
编译时我没有得到错误，我曾经想过这个身份是无效的。但目前一些设备仍在运行，但其他设备却崩溃，无法再次启动应用。我不知道如何在这里找到什么错误。 –
