$ Enter Import Password: 
$ MAC verified OK
$ Enter PEM pass phrase: 
$ Verifying - Enter PEM pass phrase:

Development Pem:

$ cat dev_cert.pem dev_key.pem > appid_development.pem

How to register notification? (Client Side)

In AppDelegate file, add methods below to register device token

#pragma mark - push notification methods

- (void)sendToken:(NSString *)token {
    
    NSString *tokenUrl = [NSString stringWithFormat:@"http://serverIP:4567/v1/apps/app1/%@", token];
    NSLog(@"tokenUrl: %@", tokenUrl);
    //prepare NSURL with newly created string
    NSURL *url = [NSURL URLWithString:tokenUrl];
    
    //AsynchronousRequest to grab the data
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    NSOperationQueue *queue = [[NSOperationQueue alloc] init];
    
    [NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
        if ([data length] > 0 && error == nil) {
