iOS Block issue with AFNetworking - ios

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

How can we pass the parameters along with block methods in objecitve-c

I want to pass the 'NSString' as a parameter for as URLString in below method, how can we do that
-(void)makeServiceCallSuccess:(void (^)(NSDictionary *response))success
failure:(void (^)(NSError *error))failure {
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:URLString parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
response = (NSDictionary *)responseObject;
success(response);
NSLog(#"JSON: %#", response);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
failure(error);
NSLog(#"Error: %#", error);
}];
}

simply add parameter in method, as usually we are doing like
-(void)makeServiceCallSuccessWithURLString:(NSString*)urlString withResponseHandler:(void (^)(NSDictionary *response))success
failure:(void (^)(NSError *error))failure

There is no wat to pass a paramether in that method as it, you can edit it and add a parameter or read a value from aproperty
-(void)makeServiceCallSuccess:(void (^)(NSDictionary *response))success
failure:(void (^)(NSError *error))failure {
NSString* myString = self.myProperty;
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:myString parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
response = (NSDictionary *)responseObject;
success(response);
NSLog(#"JSON: %#", response);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
failure(error);
NSLog(#"Error: %#", error);
}];
}

How to make a rest API Call post with multiple parameter

I am trying to have an API Call post. I can use this post command however my issue is that I have multiple parameters such as, Name, phone number, email, and multiple other private information. I have tried this method in order to get it to work but have not been successful. Thank you in advance for any help!
GET 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);
}];
or
POST URL-Form-Encoded Request
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = #{#"foo": #"bar"};
[manager POST:#"http://example.com/resources.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *parameters = #{#"foo": #"bar", #"key_param2":#"obj_param2", #"key_param3":#"obj_param3",#"key_paramN":#"obj_paramN"};
[manager POST:#"http://example.com/resources.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];

To add more parameters, just include them in your parameters dictionary like so:
NSDictionary *parameters = #{#"foo": #"bar", #"otherFoo":#"otherBar"};
Then pass 'parameters' to your post method exactly as you are currently doing.

How to save a responseObject in a Get request AFNetworking to nsarray?

I've already killed a couple terrible hours to find out how to save a responseObject in a Get request AFNetworking to nsarray. Can't figure out how to save it so I could use it in another part of my code.
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:#"example.com/resources.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];

__block NSArray* responseObjectArray = nil;
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:#"example.com/resources.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
responseObjectArray = (NSArray*)responseObject;
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];

Trying to make a function to handle AFNetworking

I'm trying to make a function that I'll call to handle the AFNetworking JSON parse.
Here is my code:
- (int)startParseWithParameters:(NSDictionary*)incomingParameters andUrlAdress:(NSString*)urlAdress;
{
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
NSDictionary *parameters = incomingParameters;
[manager POST:urlAdress parameters:parameters success:^
(AFHTTPRequestOperation *operation, id responseObject)
{
NSString *recivedErr = responseObject[#"error"];
_errValue = [recivedErr intValue];
NSLog(#"JSON: %d", _errValue);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(#"Error: %#", error);
}];
return _errValue;
}
I want the function to return 0 or 1, then I'll know if there is an error or not.
Right now it always return 0.
When I try to return in the success block I get a compiler error.
What could cause this problem?

The succes block is handled async so you should just call a method in the block:
- (void)startParseWithParameters:(NSDictionary*)incomingParameters andUrlAdress:(NSString*)urlAdress {
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
NSDictionary *parameters = incomingParameters;
__weak typeof(self) weakSelf = self;
[manager POST:urlAdress parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *recivedErr = responseObject[#"error"];
[weakSelf didReceiveResponse:[recivedErr integerValue];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
}
-(void)didReceiveResponse:(NSInteger)status {
}

AFNetworking GET request with query is not working

this is always error with -1004 ( could not connect to server )
but the request in browser is working fine.
what's wrong with my code?
(url : "http://localhost:3000/v1/voice/version?appname=wevoice")
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager GET:#"http://localhost:3000/v1/voice/version"
parameters:#{ #"appname": #"wevoice" }
success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];

You have to set the property baseURL on your request manager. Here is an example:
self.requestManager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:http://localhost:3000];
Later, in your concrete GET message to the manager, you'll only pass the relative URL path:
[self.requestManager GET:#"/v1/voice/version"
parameters:#{ #"appname": #"wevoice" }
success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
And keep in mind, that, if you want to send your paramters as JSON, you'll need a request serializer:
self.requestManager.requestSerializer = [AFJSONRequestSerializer serializer];

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSMutableDictionary *dic = [NSMutableDictionary dictionary];
[dic setObject:#"wevoice" forKey:#"appname"];
[manager GET:#"http://localhost:3000/v1/voice/version"
parameters:dic
success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
You can try this.May be the way you add Parameter is wrong.

Try this method. Hope it helps.
+ (void)getRequestWithURLStringWithSuccess:(void(^)(id object))successBlock andFail:(void(^)(NSString *errorMessage))failBlock {
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc]initWithBaseURL:[NSURL URLWithString:#"http://localhost:3000/v1/voice/version"]];
NSString *urlString = #"/version";
[manager GET:urlString parameters:#{ #"appname": #"wevoice" } success:^(AFHTTPRequestOperation *operation, id responseObject)
{
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
}
