iOS Question How to read missed calls or check phone state?

[susu]

Hi,

How can I read call log to find missed calls or at least check phone state (RINGING..) ? Phone library doesn't have any event to check it. There's an answer on Stackoverflow mention it:

Using Core Telephony framework, detect for call state changes.

I hate to call your name but please help me @Erel - The Ultimate!

It will only allow you to monitor the phone state when your app is in the foreground. What exactly are you trying to implement?

I need to verify user's phone number by make a call to him. If I can detect phone state and check it's my phone number calling, I can approve him.

You can use this code to listen for incoming calls:

Private Sub Application_Start (Nav As NavigationController)
   NavControl = Nav
   Page1.Initialize("Page1")
   NavControl.ShowPage(Page1)
   Page1.RootPanel.LoadLayout("1")
   Dim no As NativeObject = Me
   no.RunMethod("ListenForCalls", Null)
End Sub

Sub State_Changed(call As Object)
   Log("call: " & call)
End Sub

#if objc
#import <CoreTelephony/CTCallCenter.h>
- (void)ListenForCalls {
   static CTCallCenter* cc;
   cc = [[CTCallCenter alloc] init];
   [cc setCallEventHandler: ^(CTCall* call) {
  [self.bi raiseEvent:nil event:@"state_changed:" params:@[call]];
  }];
}
#end if

However it will not include the phone number. This information is not available:

Thanks Erel.
You mean there's no way to read call log or incoming call?

I think reading call logs is very simple, you only have to read the database call_history.db.

Database information: https://www.theiphonewiki.com/wiki/Call_History_Database
Reading Database: https://www.b4x.com/b4i/help/isql.html

I read about it but you only can read it when you backup that database to computer. I need to read call log inside iOS.
After some search on Google, I think it's unpossible to read call log or even know who is calling. So I need to ask user input the missed call number manually.
Ps: That's why iOS suck!
