爲什麼我的應用只會在IOS 9設備上崩潰？

我的應用程序僅在IOS 9設備上崩潰。爲什麼？什麼在IOS 9這使它崩潰？這裏是調試控制檯日誌...爲什麼我的應用只會在IOS 9設備上崩潰？

任何想法？

我綁將此代碼添加到Info.plist文件，但它仍然崩潰...

<key>NSAppTransportSecurity</key> 
     <dict> 
       <key>NSAllowsArbitraryLoads</key><true/> 
     </dict>

它不是重複的，它是關於新錯誤的新問題。 –

即使不是重複的，如果沒有完善的問題或SSCCE，這是一個糟糕的問題。 – user2864740

它說的錯誤消息：

Exception 'NSInvalidArgumentException', 
reason: '*** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]:  
     attempt to insert nil object from objects[0]

因此很明顯，要插入無對象作爲第一項。

我知道，但爲什麼這只是發生在IOS 9？ –

要回答**調試**代碼，並找出它究竟爲什麼會崩潰。您可以使用lldb，斷點，單步執行，print（）等工具。 – zaph

爲什麼我的應用只會在IOS 9設備上崩潰？
