No visible #interface for 'AFHTTPSessionManager' declares the selector 'POST:parameters:progress:success:failure:'
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
manager.operationQueue.maxConcurrentOperationCount = 10;
[manager POST:[url absoluteString] parameters:params progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSDictionary *response = (NSDictionary *)responseObject;
NSNumber* remoteAppVersion = [response objectForKey:#"ApplicationVersion"];
[self setLocalAppVersion:remoteAppVersion];
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(#"Error occured while getAppVersion. Error : %#",error);
[self updateAppCompleted];
}];
}
I upgraded afnetworking 4.0 and got this error in my get and post operations. Can you help me how can i fix this problem

I'm using AFHTTPSessionManager in singleton mode, and start multiple request like :
[MyAPI testSlow];
[MyAPI testQuick];
MyAPI definition:
+(void)testSlow {
AFHTTPSessionManager *manager = [BPNetworkManager sharedManager]; // Get Manager Singleton
NSString *urlString = [BPCommonUtils getUrlByPath:#"/api/test/testSlow"];
[manager GET:urlString parameters:nil success: ^(NSURLSessionTask *operation, id responseObject) {
NSLog(#"slowSuccess");
} failure:^(NSURLSessionTask *operation, NSError *error){
NSLog(#"slowFail");
}];
}
+(void)testQuick {
AFHTTPSessionManager *manager = [BPNetworkManager sharedManager];
NSString *urlString = [BPCommonUtils getUrlByPath:#"/api/test/testQuick"];
[manager GET:urlString parameters:nil success: ^(NSURLSessionTask *operation, id responseObject) {
NSLog(#"quickSuccess");
} failure:^(NSURLSessionTask *operation, NSError *error){
NSLog(#"quickFail");
}];
}
When 'quick Task' returned with success, the 'slow Task' failed immediately, fail message info :
#"NSURLErrorDomain" - code: 18446744073709550617
#"NSLocalizedDescription" : #"cancelled"
How can I solve it? Thank you!
I have a few requests that needs to fire one by one while depending on the previous response.
That was pretty straight forward with NSOperation and trying to figure out
what's the best approach here with Sessions & AFNetworking >= 3.0
-(void)startGet
{
NSString *urlStr = [NSString stringWithFormat:#"https://test.com/test?%ld",(long)test];
NSURL *URL = [NSURL URLWithString:urlStr];
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
NSLog(#"NUMBER: %ld",(long)test);
[manager GET:URL.absoluteString parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(#"task: %#",task.currentRequest.URL.absoluteString);
} failure:^(NSURLSessionTask *operation, NSError *error) {
//NSLog(#"Error: %#", error);
}];
}
- (void)viewDidLoad {
[super viewDidLoad];
for (int i=0; i<10; i++)
{
test = i;
[self startGet];
}
}
The log I want to get is:
https://test.com/test?0
https://test.com/test?1
https://test.com/test?2
https://test.com/test?3
https://test.com/test?4
https://test.com/test?5
https://test.com/test?6
...
Things I've tried:
...
dispatch_group_t serviceGroup = dispatch_group_create();
...
-(void)startGet
{
NSString *urlStr = [NSString stringWithFormat:#"https://test.com/test?%ld",(long)test];
NSURL *URL = [NSURL URLWithString:urlStr];
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
NSLog(#"NUMBER: %ld",(long)test);
dispatch_group_enter(serviceGroup);
[manager GET:URL.absoluteString parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(#"task: %#",task.currentRequest.URL.absoluteString);
dispatch_group_leave(serviceGroup);
} failure:^(NSURLSessionTask *operation, NSError *error) {
dispatch_group_leave(serviceGroup);
//NSLog(#"Error: %#", error);
}];
dispatch_group_wait(serviceGroup,DISPATCH_TIME_FOREVER);
}
Although the request came out in the right order I would still get mixed responses like so:
https://test.com/test?4
https://test.com/test?7
https://test.com/test?1
https://test.com/test?3
I'm not sure if something is wrong with the code or I totally misunderstood the purpose of dispatch_group_t in that case.
I've digged around and saw a comment by matt from AFNetworking about integrating a simple solution using Operations & session in AF and it is soon to be public but it was over 2 years ago.
I'm trying to solve this without using nested requests or NSOperations
Thanks
You can try out 2 approaches
Semaphore
dispatch_semaphore_t semaphore = dispatch_semaphore_create(0);
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
NSLog(#"NUMBER: %ld",(long)test);
[manager GET:URL.absoluteString parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
dispatch_semaphore_signal(semaphore);
NSLog(#"task: %#",task.currentRequest.URL.absoluteString);
} failure:^(NSURLSessionTask *operation, NSError *error) {
//NSLog(#"Error: %#", error);
}];
dispatch_semaphore_wait(semaphore, DISPATCH_TIME_FOREVER);
WaitUntillFinished
[operation waitUntilFinished];
You can check for detailed implementation at below link:
https://github.com/AFNetworking/AFNetworking/issues/1804
in my app I'm using the new AFN 3.0 and I have
AFHTTPSessionManager *manager
instead of
AFHTTPRequestOperation *operation
my problem is that before I was able to get some data from RequestOperation as:
NSURL *url = operation.request.URL;
//or
NSNumber statusCode = operation.response.statusCode;
//or
NSData *responseData = operation.responseData;
and how can I get this elements with AFHTTPSessionManager?
thanks
in v2 you were getting AFHTTPRequestOperation for the request
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:#"http://example.com/resources.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
But in the v3 you will get NSURLSessionTask
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
[manager GET:#"http://example.com/resources.json" parameters:nil progress:nil success:^(NSURLSessionTask *task, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(NSURLSessionTask *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
So based on that you can get the details the from the NSURLSessionTask like the currentRequest , response etc
For more changes and details, you can refer to the migration guide of AFNetworking

For NSURLSessionTask Reference : NSURLSessionTask
I'm currently learning blocks, and I want to use them with AFNetworking. I made method in Singletone:
- (void)getAllPlayers:(void (^)(NSArray *playerz, bool succeed))blockPlayers {
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:#"https://api.myjson.com/bins/530re" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
}
I called this method in viewDidLoad:
[[Manager sharedInstance]getAllPlayers:^(NSArray *playerz, bool succeed) {
if (succeed == YES) {
self.allClubs = playerz;
[self.tableView reloadData];
}
}];
But nothing is downloaded.
Yo forgot to call the blockPlayers Completion handler.
- (void)getAllPlayers:(void (^)(NSArray *playerz, bool succeed))blockPlayers {
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:#"https://api.myjson.com/bins/530re" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSarray *returnedPLayerz = [NSArray array];
//Here treat operation and response Object to extract playerz and assing it to returnedPlayerz
blockPLayers(returnedPlayerz, YES);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
blockPlayers(nil, NO);
NSLog(#"Error: %#", error);
}];
}
You got data from server in response object. After that you need to parse it and return in block:
- (void)getAllPlayers:(void (^)(NSArray *playerz, bool succeed))blockPlayers {
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:#"https://api.myjson.com/bins/530re" parameters:nil
success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSArray* players = [self getPlayersFromJson:responseObject];
blockPlayers(players, YES);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
blockPlayers(nil, NO);
}];
}
So you need to create parser method getPlayersFromJson
I'm trying to do a POST with action parameter called "#load".
To my webservice is a key need to show results: action:#load
How I can do this using AFNetworking framework? Here a sample of my wrong code:
First the constant declaration:
const NSString *BASE_URL = #"http://www.mywebservice.com/request.php";
Now the code:
-(void)requisitarEventos{
[smartEventos removeAllObjects];
NSString* url = [BASE_URL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[SVProgressHUD showWithStatus:#"Loading..." maskType:SVProgressHUDMaskTypeGradient];
NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:#"#load",#"action", nil];
[manager POST:url parameters:parameters
success:^(AFHTTPRequestOperation *operation, id responseObject) {
[self carregarEventos:responseObject];
[SVProgressHUD dismiss];
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
[SVProgressHUD dismiss];
}];
}
I found the answer. The real problem of my code that's my Web Service doesn't give results of Content-Type in "application/json", but in "text/html".
I solve the problem using this code below:
NSMutableSet *contentTypes = [[NSMutableSet alloc] initWithSet:manager.responseSerializer.acceptableContentTypes];
[contentTypes addObject:#"text/html"];
manager.responseSerializer.acceptableContentTypes = contentTypes;
And the full code of my class:
-(void)callEvents{
[smartEvents removeAllObjects];
NSString* url = [NSString stringWithFormat:#"%#myService.php?action=load", BASE_URL];
url = [url stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[SVProgressHUD showWithStatus:#"Loading..." maskType:SVProgressHUDMaskTypeGradient];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
NSMutableSet *contentTypes = [[NSMutableSet alloc] initWithSet:manager.responseSerializer.acceptableContentTypes];
[contentTypes addObject:#"text/html"];
manager.responseSerializer.acceptableContentTypes = contentTypes;
[manager GET:url parameters:nil
success:^(AFHTTPRequestOperation *operation, id responseObject) {
[self carregarEventos:responseObject];
[SVProgressHUD dismiss];
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
[SVProgressHUD dismiss];
}];
}
please see this , I make a simple post method with callback ,
POST with URL parameters and JSON body in AFNetworking
