Twilio crash while building the app in device in IOS

Question

I have added Twilio SDK and libJingleConnection through cocoa pods.

Twilio libraries like libssl.a , libcryto.a is getting conflicts with Libjingle_Connection libraries like libwebrtc.a so twilio is crashing.. Without integrating libjingle_connection.

Twilio integration is working fine.!

It is similar to below problem

When using Twilio iOS sdk and building Cordova app openssl crashes

But I need to keep both libjingle_connection and twilio in my project.

When I build the app in device. My app is crashing as below..

My other linker flags are -ObjC and $(inherited)

I am not able to find the cause of crash..

Please suggest any solutions to fix the error..

Thanks in Advance...!

Answer 1

Hiii ,

Please Follow the steps to integrate twilio in app .

step 1 : import required Frameworks

step 2: Copy the Headers and Library Folders into Your Project .

Step 3: Add other Linker flags ( not only -ObjC but -lTwilioClient,-lcrypto,-lssl)

step 4: Add Header and Library search paths

Path of header folder you copied : $(SRCROOT)/Headers

Path of Library folder you copied : $(SRCROOT)/Libraries

step 5: Add prefix header file

#import <Availability.h>
#ifndef __IPHONE_4_0
#warning "This project uses features only available in iOS SDK 4.0 and later."
#endif
#ifdef __OBJC__
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#import <CoreData/CoreData.h>
#endif

Make Precompile Prefix header to yes in build settings , and path of .pch file .

After This steps your project should compile and build , you can run it but , to use twilio you need to generate capabilities token .

step 6 :From Twilio's BasicPhone example copy basicPhone.h and basicPhone.m file in your project .

then in Appdelegate create an global object that we can access through out in project .

in appdelegate.h

@class BasicPhone;
@interface AppDelegate : UIResponder <UIApplicationDelegate>{


BasicPhone *_phone;
}
@property (strong, nonatomic)BasicPhone *phone;

synthesize it in appDelegate.m file

@synthesize phone = _phone;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
if ([UIApplication instancesRespondToSelector:@selector(registerUserNotificationSettings:)]){
    /* iOS 8.0 later */
    [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert|
                                                   UIUserNotificationTypeBadge|
                                                   UIUserNotificationTypeSound
                                                                                    categories:nil]];
}   
self.phone = [[BasicPhone alloc] init];
}

step 7: capabilities Token :

Check this Link for how to generate capabilities token .

step 8 : create a makeCall.php file and in your twiML app (Twilio acc) set it's link for making calls .

step 9 : from xcode register with client .

In your basicPhone.h file

#define BPDefaultClientName @"abc"
#define BPCapabilityTokenKeyIncomingClient @"abc"

and in you basicPhone.m method you must have the function

getCapabilityTokenWithParameters

Change the urlString there with your capabilitiesToken url .

If you want both incoming and out going then your capabilities token url should be like this :

https://abc.herokuapp.com/token?allowOutgoing=true&client=abc

step 10 : in your viewcontroller.h login into twilio

Create an object of basicPhone

@class BasicPhone;
@interface ViewController : UIViewController{

BasicPhone* _phone;
}
@property (nonatomic,retain) BasicPhone* phone;

in ViewController.m

@synthesize phone=_phone;
- (void)viewDidLoad {
[super viewDidLoad];
AppDelegate* delegate = (AppDelegate*)[UIApplication sharedApplication].delegate;
    BasicPhone* basicPhone = delegate.phone;

    [basicPhone login];
}

To make outGoing Calls :

NSDictionary* dictParams = [NSDictionary dictionaryWithObjectsAndKeys:@"xyz", @"To", nil];
NSLog(@"%@",dictParams);
AppDelegate* delegate = (AppDelegate*)[UIApplication sharedApplication].delegate;
BasicPhone* basicPhone = delegate.phone;
[basicPhone connectWithParams:dictParams];

This is how I did and Its working without any issue .

I will feel good If it helps .

Answer 2

remove -objC from other linker flag. It worked for me
