Error while registering user in smp 3.0 through https in IOS.

Hi every one,

I am getting below  error for user registration in SMP 3.0  From IOS device.

Server Version: SMP 3.0 sp04.

IOS version: IOS 7 and IOS 8.

CFNetwork SSLHandshake failed (-9807)

"A connection failure occurred: SSL problem (possibly a bad/expired/self-signed certificate).

Below is the code i am using for Registration:

SMPClientConnection *clientConnection  =[SMPClientConnectioninitializeWithAppID:serverSettings.appIDdomain:@"default"secConfiguration:serverSettings.securityConfiguration];

    if ([self.appConnectionIDlength]>0 ) {

        [clientConnection  setApplicationConnectionID:self.appConnectionID];

    }

[clientConnection setConnectionProfileWithHost:serverSettings.smpHostAddressport:serverSettings.mbsPortfarm:nilrelayServerUrlTemplate:nilenableHTTP:NO];

self.userRegistorDelegate =delegate;

    SMPUserManager *userManager =[SMPUserManagerinitializeWithConnection:clientConnection];

    NSError *error;

    if ([self.appConnectionIDlength] ==0 )

    {

        BOOL isUserRegistored = [userManager registerUser:self.gateWayUserNamepassword:self.gateWayUserPassworderror:&error isSyncFlag:NO];

        if (isUserRegistored)

        {

            [self.userRegistorDelegateuserRegistrationSuccessful:userManager];

        }

        else

        {

            [userManager setRegistrationError:error];

            [self.userRegistorDelegateuserRegistrationFailed:userManager];

        }

    }

    else

    {

        [self.userRegistorDelegateuserRegistrationSuccessful:userManager];

    }

can any one suggest me how to solve this issue ?
