Hi, I added crt file into bundles and used this code

NSString *certPath = [[NSBundle bundleForClass:[self class]] pathForResource:@"PushCrt" ofType:@"crt"];
  NSData *certData = [NSData dataWithContentsOfFile:certPath];
  [XMCenter addSSLPinningCert:certData];
  [XMCenter addSSLPinningURL:@"https://*****.net"];
  
  
  [XMCenter sendRequest:^(XMRequest *request) {
      request.url = [NSString stringWithFormat:@"https://*****:8801/api/v2/tokens"];
      request.parameters = @{@"device": @"ios", @"token" : @"aa", @"channel" : @"default"};
      request.httpMethod = kXMHTTPMethodPOST;
      request.headers = @{@"X-AN-APP-NAME" : @"**", @"X-AN-APP-KEY" : @"**"};
      //request.responseSerializerType = kXMResponseSerializerJSON;
  } onSuccess:^(id responseObject) {

      NSLog(@"%@",responseObject);
      
  } onFailure:^(NSError *error) {
      
      NSLog(@"%@",error);
      NSLog(@"%@",[error localizedFailureReason]);
      
  } onFinished:^(id responseObject, NSError *error) {
      
  }];
