Error Undefined symbols for architecture x86_64:

问题

I'm working in a project with a map framework and all it's fine until I starts with the push notifications and write @property bool push; in my the AppDelegate.h. I have this in my AppDelegate.m

(void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken {

NSString *key =[[NSUserDefaults standardUserDefaults] stringForKey:@"token"];

if ( key== nil || [key isEqual:@""])
{
    _push=true;
    NSString* token = [[[[deviceToken description] stringByReplacingOccurrencesOfString: @"<" withString: @""] stringByReplacingOccurrencesOfString: @">" withString: @""] stringByReplacingOccurrencesOfString: @" " withString: @""] ;
    NSLog(@"=== Device token: %@", token);
    NSUserDefaults *userdefault = [NSUserDefaults standardUserDefaults];
    [userdefault setObject:token forKey:@"token"];

    NSString *jsonPostBody = [NSString stringWithFormat:@"{\"token\":"
                              "\"%@\""
                              ",\"type\":"
                              "\"ios\""
                              "}",
                              [token stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

    NSData *postData = [jsonPostBody dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];

    NSURL *url = [NSURL URLWithString:@"http://www.turismolapalmadelcondado.es/es/api/push_notifications"];

    NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:url
                                                           cachePolicy:NSURLRequestReloadIgnoringLocalCacheData
                                                       timeoutInterval:180.0];
    [request setHTTPMethod:@"POST"];
    [request setHTTPBody:postData];
    NSString* postDataLengthString = [[NSString alloc]initWithFormat: @"%d", [postData length]];
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request setValue:postDataLengthString forHTTPHeaderField:@"Content-Length"];

    NSURLResponse *response = nil;
    NSError *error = nil;
    NSData *data=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
    NSHTTPURLResponse *httpResponse = response;
    NSLog(@"response text: %@",[[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding] );
    NSLog(@"response status code: %ld", (long)[httpResponse statusCode]);
}

}

The thing is that if I don't define push I have a error in the AppDelegate.m but If I do it have 93 with the same error in the framework. I didn't have any problem before and I almost tried all the solutions I've found here.

If you need something more information, please tell me.

Thanks.

Finally I was able to fix the error. I had the error in a specific framework but maybe I can help someone. It really was a configuration error project, if you're using as me an opensource framework read the documentation carefully to requirements, in my case was two things that I need to make it work and I couldn't find, I knew not who waslooking until I saw some files that need and don't have. Apart from this, the version of ios of framework or things like enabling or not Bitcode or arc, in my case I had to enable Bitcode in debug but not in release. To know this just looking at settings of framework an patiente. I hope mi experience can hepl someone.
