I am using AFNetworking for making URL call.I check this url's in Android.This URL content-type is Application/JSON but in IOS i am getting header content-type text/html.From this URL I am getting sucessful response from URL in JSON format.Please help for solve this issue.
This is my ViewController.m file
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
NSURL *URL = [NSURL URLWithString:#"http://wptrafficanalyzer.in/p/demo1/first.php/countries/"];
NSURLRequest *request = [NSURLRequest requestWithURL:URL];
NSURLSessionDataTask *dataTask = [manager dataTaskWithRequest:request completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
if (error) {
NSLog(#"Error: %#", error);
} else {
NSLog(#"%# %#",response);
}
}];
[dataTask resume];
}

Answer 1

Add this code:
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
After this :
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];
It is well explained here : Upload an sqlite file
Your server page is returning text/html, but AFURLSessionManager is expecting JSON.
Edit:
As the above solution didn't work out , i found this link containing all possible solution for this error : Request failed: unacceptable content-type: text/html
