[英]Segmentation fault 11 only for xcode 10 swift 3
我將xcode 9.4和swift 3一起使用時,代碼可以正常工作,並且實時運行。 現在,當我在xcode 10.1中運行相同的代碼時,許多文件出現很多segmentation fault 11
錯誤。不確定如何執行此操作。如何將swift 3轉換為swift4。因為許多文件都需要更改語法。
更好的是,我需要在xcode 10.1中使用swift 3並需要解決該segmentation fault 11
。
我進入這里的主要錯誤:
- 在/Users/Documents/Rough/jeder/JEDE_r/AppDelegate.swift:258:5為'application(_:didReceiveRemoteNotification :)'發出SIL時
- 而silgen發出了SIL函數“ @ $ S3WCi11AppDelegateC11application_28didReceiveRemoteNotificationySo13UIApplicationC_SDys11AnyHashableVypGtF”。 /Users/Documents/Rough/jeder/JEDE_r/AppDelegate.swift:258:5中的'application(_:didReceiveRemoteNotification :)'的錯誤:細分錯誤:11
我的代碼:
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any])
{
if application.applicationState == .inactive || application.applicationState == .background {
//opened from a push notification when the app was on background
}
else
{
if application.applicationState == .active
{
let myuserinfo = userInfo as NSDictionary
print(myuserinfo)
let tempDict:NSDictionary = (myuserinfo.value(forKey: "aps") as? NSDictionary)!
let alert = UIAlertView(title: "alertView", message: (tempDict.value(forKey: "alert") as? String)!, delegate: nil, cancelButtonTitle:"Cancel", otherButtonTitles: "Done", "Delete")
alert.show()
let person:NSDictionary = (tempDict.value(forKey: "custom") as? NSDictionary!)!
}
}
}
這里有什么問題。 我如何才能解決所有的segmentation fault 11
錯誤,將近22個文件顯示了該錯誤。
任何幫助,請!
改變這一行:
let person:NSDictionary = (tempDict.value(forKey: "custom") as? NSDictionary!)!
至
let person:NSDictionary = (tempDict.value(forKey: "custom") as? NSDictionary)!
同樣在同一appdelegate一種方法中,您也一樣。 用上面的那一行代替。 可能是這個幫助。 讓我知道或發布任何其他問題(如果有)。
請嘗試下面的代碼
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any])
{
if application.applicationState == .inactive || application.applicationState == .background {
//opened from a push notification when the app was on background
}
else
{
if application.applicationState == .active
{
let myuserinfo = userInfo as NSDictionary
print(myuserinfo)
let tempDict:NSDictionary = ((myuserinfo.value(forKey: "aps") as? NSDictionary))!
let alert = UIAlertController(title: "alertView", message: (tempDict.value(forKey: "alert") as? String)!, preferredStyle: .alert)
let ok = UIAlertAction(title: "OK", style: .default, handler: nil)
alert.addAction(ok)
//alert.show()
self.window?.rootViewController?.present(alert, animated: true, completion: nil)
let _:NSDictionary = (tempDict.value(forKey: "custom") as? NSDictionary)!
}
}
}
