iOS集成使用VialerSIPLib

PJSIP拨打电话库：VialerSIPLib，这个应该是Github上能找到上手门槛比较低并且比较强大的PJSIP库了。

0、运行GitHub上VialerSIPLib的Demo

0.1、clone 或 下载zip，然后pod install

0.2、修改Keys.swift.example文件名为Keys.swift，并为Keys.swift中的属性赋值

可能会出现错误PJSUA_IP_CHANGE_OP_COMPLETED 未定义，将VSLEndpoint.m中这段代码注释了即可

//        case PJSUA_IP_CHANGE_OP_COMPLETED: {
//            VSLLogDebug(@"The ip change process has completed, status: %s", statusmsg);
//            [VSLEndpoint sharedEndpoint].ipChangeInProgress = NO;
//            break;
//        }

1、集成

pod 'VialerSIPLib', "3.7.3"

1.1、同时添加一下代码

post_install do |installer_representation|
    installer_representation.pods_project.targets.each do |target|
        target.build_configurations.each do |config|
            config.build_settings['ONLY_ACTIVE_ARCH'] = 'NO'
          config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= ['$(inherited)']
            config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] << 'PJ_AUTOCONF=1'
            config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '10.0'
        end
    end
end

1.2、如果Podfile文件中使用了use_frameworks!，需添加一下代码。否则会报“The ‘Pods-XXX‘ target has transitive dependencies that include statically linked binaries”

pre_install do |installer|
  # workaround for https://github.com/CocoaPods/CocoaPods/issues/3289
  Pod::Installer::Xcode::TargetValidator.send(:define_method, :verify_no_static_framework_transitive_dependencies) {}
end

2、使用

2.1、配置VialerSIPLib

- (void)configureVialerSIPLib
{
    VSLEndpointConfiguration *endpointConfiguration = [[VSLEndpointConfiguration alloc] init];
    VSLTransportConfiguration *updTransportConfiguration = [VSLTransportConfiguration configurationWithTransportType:VSLTransportTypeUDP];

    endpointConfiguration.transportConfigurations = @[updTransportConfiguration];

    NSError *error;
    BOOL success = [[VialerSIPLib sharedInstance] configureLibraryWithEndPointConfiguration:endpointConfiguration error:&error];
    if (!success || error) {
        NSLog(@"Failed to startup VialerSIPLib: %@", error);
    }
}

2.2、注册SIP账号

- (void)addSipUser
{
    FGSipUserModel *model = [[FGSipUserModel alloc] init];
    model.sipAccount = @"";
    model.sipPassword = @"";
    model.sipDomain = @"";
    model.sipProxy = @"xxx.xxx.xxx:5060";
    
    NSError *error;
    self.account = [[VialerSIPLib sharedInstance] createAccountWithSipUser:model error:&error];
    if (error) {
        NSLog(@"Failed to create Account: %@", error);
    } else {
        NSLog(@"Succeed to create Account");
    }
}

1.上面的FGSipUserModel类需实现SIPEnabledUser协议.
2.这里的self.account这样定义@property (nonatomic, strong) VSLAccount *account;，最好是作为AppDelegate的属性。

// FGSipUserModel.h
#import <Foundation/Foundation.h>
#import <VialerSIPLib/VialerSIPLib.h>

@interface FGSipUserModel : NSObject<SIPEnabledUser>
@property (nonatomic, readwrite) NSString *sipAccount;
@property (nonatomic, readwrite) NSString *sipPassword;
@property (nonatomic, readwrite) NSString *sipDomain;
@property (nonatomic, readwrite) NSString *sipProxy;
@end

// FGSipUserModel.m
#import "FGSipUserModel.h"

@implementation FGSipUserModel
@synthesize sipAccount = _sipAccount;
@synthesize sipPassword = _sipPassword;
@synthesize sipDomain = _sipDomain;
@synthesize sipProxy = _sipProxy;
@end

2.3、拨打电话

[[VialerSIPLib sharedInstance].callManager startCallToNumber:@"8007"
                                                  forAccount:self.account
                                                  completion:^(VSLCall * _Nullable call, NSError * _Nullable error) {
        if (error) {
            NSLog(@"Call error：%@", error);
        }
}];
