This example allows to place outgoing audio call with one button click using account specified in server config file
/usr/local/FlashphonerWebCallServer/conf/apps/click-to-call/accounts.xml
To analyze the code, let's take ClickToCall example version, which can be downloaded with build 2.5.2.
View class for the main view of the application: ViewController (header file ViewController.h; implementation file ViewController.m).
1. Import of API. code
#import <FPWCSApi2/FPWCSApi2.h> |
2. Connection to the server.
FPWCSApi2 createSession, FPWCSApi2Session connect code
FPWCSApi2SessionOptions object with the following parameters is passed to createSession() method
- (FPWCSApi2Session *)connect { FPWCSApi2SessionOptions *options = [[FPWCSApi2SessionOptions alloc] init]; options.urlServer = _connectUrl.text; options.appKey = @"clickToCallApp"; NSError *error; session = [FPWCSApi2 createSession:options error:&error]; ... [session connect]; return session; } |
3. Receiving the event confirming successful connection.
ViewController onConnected, ViewController call code
Onthis event, ViewController call method is called to make outgoing call.
- (void)onConnected:(FPWCSApi2Session *)session { [self onHangup]; [self call]; } |
4. Outgoing call.
FPWCSApi2Session createCall, FPWCSApi2Call call code
The next options are passed to the createCall() method:
- (FPWCSApi2Call *)call { FPWCSApi2CallOptions *options = [[FPWCSApi2CallOptions alloc] init]; options.callee = _callee.input.text; options.localConstraints = [[FPWCSApi2MediaConstraints alloc] initWithAudio:YES video:NO]; NSError *error; call = [session createCall:options error:&error]; ... [call call]; return call; } |
5. Call hangup.
FPWCSApi2Call hangup code
- (void)callButton:(UIButton *)button { [self changeViewState:button enabled:NO]; if ([button.titleLabel.text isEqualToString:@"HANGUP"]) { if (call) { [call hangup]; } ... } } |
