AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:@"http://google.com/"]];
NSMutableURLRequest *request = [httpClient requestWithMethod:@"GET"
path:@"http://google.com/api/pigs/"
parameters:nil];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[httpClient registerHTTPOperationClass:[AFHTTPRequestOperation class]];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
// Print the response body in text
NSLog(@"Response: %@", [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];
[operation start];

You can also use AFHTTPRequestOperation:
您还可以使用 AFHTTPRequestOperation：
NSOperationQueue *networkQueue = [[NSOperationQueue alloc] init];
networkQueue.maxConcurrentOperationCount = 5;
NSURL *url = [NSURL URLWithString:@"https://example.com"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc]
initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *string = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(@"%@", string);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"%s: AFHTTPRequestOperation error: %@", __FUNCTION__, error);
}];
[networkQueue addOperation:operation];

please try below answer.
+(void)callAFWS:(NSDictionary *)dict withURL:(NSString *)strUrl
withToken:(NSString *)strToken withBlock:(dictionary)block
{
AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
[manager.requestSerializer setValue:strToken forHTTPHeaderField:@"Authorization"];
[manager GET:[NSString stringWithFormat:@"%@/%@",WebserviceUrl,strUrl] parameters:dict progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
if (!responseObject)
{
NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
[dict setObject:ServerResponceError forKey:@"error"];
block(responseObject);
return ;
}
block(responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
[dict setObject:ServerResponceError forKey:@"error"];
block(dict);
}];
