AFNetworking 2.0 - ios

Question

I'm a newbie in iOS development and I'm trying to figure out how to send GET request with AFNetworking.
I used the example provided in Tutorial on Using AFNetworking 2.0 and placed it in main expecting a error:
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:#"http://samwize.com/api/poos/"
parameters:nil
success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
...and I've got nothing, so I tried to point to the webservice that returns a valid JSON and also got nothing. Why none of blocks (success or failure) are executed?

Answer 1

Your code does not execute blocks (success or failure) beacause somthing went wrong.
but if you use try catch block then it will go into catch block try once.
code:
try {
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:#"http://samwize.com/api/poos/"
parameters:nil
success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
}#catch (NSException *exception) {
**// you will get error here**
}

Use following function and just send your URL in Argument
- (void)callWebservice : (NSString *)strURL{
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:[NSURL urlWithEncoding:strURL]];
[httpClient registerHTTPOperationClass:[AFJSONRequestOperation class]];
[httpClient setDefaultHeader:#"Accept" value:#"application/json"];
[httpClient setParameterEncoding:AFJSONParameterEncoding];
NSMutableURLRequest *request = [httpClient requestWithMethod:#"GET" path:#"" parameters:nil];
[request setTimeoutInterval:180];
[AFJSONRequestOperation addAcceptableContentTypes:[NSSet setWithObject:#"text/html"]];
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON)
{
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
NSLog(#"Success");
} failure:^ (NSURLRequest *request, NSURLResponse *response, NSError *error, id json){
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
NSLog(#"Failure");
}];
[GlobalManager setOperationInstance:operation];
[operation start];
}

It was strange, I just created another project (iOS instead of OSX) and called the same code from the IBAction and it worked easily. In Podfile I specified a new version of AFNetworking (2.5 instead of 2.4). I don't know if this is relevant.
Thank you everyone for trying to help me.

Try following code to do that.
#try {
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
[manager GET:stringURL parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject){
NSLog(#"JSON: %#", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];
}
#catch (NSException *exception) {
NSLog(#"Exception - %#", [exception debugDescription]);
}
#finally {
}
And make sure you have a valid JSON.
