xCode：如何修复线程5：EXC_BREAKPOINT（代码= 1，子代码= 0x10025c76c） [英] xCode: how to fix Thread 5: EXC_BREAKPOINT (code=1, subcode=0x10025c76c)

问题描述

当我点击iPhone中的btnLogin时，xCode显示错误：

线程5：EXC_BREAKPOINT（代码= 1，子代码= 0x10025c76c）

这是我的代码

  @IBOutlet weak var abc：UILabel！ 
 
 ... 
 
 @IBAction func btnLogin（发件人：UIButton）{
 
 var jsonResult = AnyObject？（）
 
 let urlAsString =lifewinner2015.dlinkddns.com/SERVER/user?function=login&username=Shing&password=123456789
 
 let url = NSURL（string：urlAsString）
 
 let urlSession = NSURLSession.sharedSession（）
 
 let jsonQuery = urlSession.dataTaskWithURL（url！，completionHandler：{data，reponse，error  - > Void in 
 if（错误！ = nil）{
 print（error）
} 
 
 do {
 jsonResult =尝试NSJSONSerialization.JSONObjectWithData（data！，options：.AllowFragments）as！ NSDictionary 
让jsonAbc：String！= jsonResult！[return] as！String 
 
 dispatch_async（dispatch_get_main_queue（），{
 self.abc.text = jsonAbc 
}）
} catch错误为NSError！{
 if（err！= nil）{
 print（JSON Error）
} 
} 
}）
 jsonQuery.resume（）
 
} 
  

1. 在iPhone上运行应用程序（9.2版本）


2. 点击登录按钮



3. xCode将显示错误（照片1）

   或删除断点只需将其拖放到show breakpoint navigator

   
   
   
   
   
   

   还有一件事情不要强行打开包装..如果让我们解开，请使用

    如果让jsonAbc = jsonResult！[return]为？字符串{
    dispatch_async（dispatch_get_main_queue（），{
    self.abc.text = jsonAbc 
   }）
   } 
     

   在此回答查看Interface Builder中的窗口并尝试临时删除对View Controller中存在的任何IBOutlet的所有引用

   
   

   when I click the btnLogin in the iPhone the xCode was displayed the error:

   Thread 5: EXC_BREAKPOINT (code=1, subcode=0x10025c76c)

   this is my code

   @IBOutlet weak var abc: UILabel!
   
      ...
   
   @IBAction func btnLogin(sender: UIButton) {
   
       var jsonResult = AnyObject?()
   
       let urlAsString = "lifewinner2015.dlinkddns.com/SERVER/user?function=login&username=Shing&password=123456789"
   
       let url = NSURL(string: urlAsString)
   
       let urlSession = NSURLSession.sharedSession()
   
       let jsonQuery = urlSession.dataTaskWithURL(url!, completionHandler: {data, reponse, error -> Void in
           if (error != nil) {
               print("error")
           }
   
           do {
               jsonResult = try NSJSONSerialization.JSONObjectWithData(data!, options: .AllowFragments) as! NSDictionary
               let jsonAbc: String! = jsonResult!["return"] as! String
   
               dispatch_async(dispatch_get_main_queue(), {
                   self.abc.text = jsonAbc
               })
           } catch let err as NSError! {
               if (err != nil) {
                   print("JSON Error")
               }
           }
       })
       jsonQuery.resume()
   
   }
   

   1. run the app on the iPhone (9.2 Version)
   2. click the Login button

   3. xCode will display the error(Photo 1)

   please help me to fix this error please.

   but I am not to add the breakpoint to the line number

   解决方案

   I think thats not an error ... its breakpoint .. just remove it or continue program execution like below

   or for remove breakpoints just drag and remove it from show breakpoint navigator

   one more thing don't make force unwrap.. use if let to unwrap like

   if let jsonAbc = jsonResult!["return"] as? String{
          dispatch_async(dispatch_get_main_queue(), {
               self.abc.text = jsonAbc
           })
   }  
   

   one more possibility is added in this answer that "Take a look at the Window in Interface Builder and try to temporary remove all reference to any IBOutlet present in the View Controller"
