为了发送获取数据的请求，您必须在info.plist中添加密钥，如下所示：

只需更新您的代码，如下所示：

NSError *error;
NSDictionary *dicData = [[NSDictionary alloc] initWithObjectsAndKeys:@"user123", @"username", @"pass1234", @"password", @"pass1234", @"cpassword", @"0123456789", @"mobile", @"User", @"firstname", @"Name", @"lastname", @"register", @"action", nil];
NSLog(@"parameter=%@",dicData);

//    NSURLComponents *components = [NSURLComponents componentsWithString:@"http://followerlikes.com/app_appoint/json/?action=register"];
//    
//    NSMutableArray *queryItems = [NSMutableArray array];
//    for (NSString *key in dicData) {
//        [queryItems addObject:[NSURLQueryItem queryItemWithName:key value:dicData[key]]];
//    }
//    components.queryItems = queryItems;




NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://followerlikes.com/app_appoint/json/?action=register"]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
NSData *postData = [NSJSONSerialization dataWithJSONObject:dicData options:0 error:&error];
[request setHTTPBody:postData];


NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionDataTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {

    NSLog(@"Data : %@",data);
    NSLog(@"RESPONSE : %@",response);
    NSLog(@"ERROR : %@",error);

    NSString *strRes = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
    NSLog(@"%@",strRes);
    NSError *resultError;

    NSDictionary *dicResult = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&resultError];
    NSLog(@"RESPONSE DICT : %@", dicResult);

    dispatch_async(dispatch_get_main_queue(), ^ {

       if (error !=nil) {
           NSLog(@"ERROR : %@",error.description);
           NSLog(@"ERROR : %@",error.localizedDescription);
       }
       else {
//                               completion(dicResult);
       }
   });
}];

[task resume];
