Answer 1

it happens

NSLocalizedDescription=Request failed: unacceptable content-type: text/html

format Content-Type" = "text/html doesn't have your AFNetworking.

Simply go to Serilization->AFURLResponseSerialization.m, line 215, and change it:

self.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html", nil];

it will work you.

More recent versions may have the code on line 223.

I have done this and it worked too but will it affect any other response?? – Braga

Answer 2

Solution for Swift:

It will accept most of the content type.

let manager=AFHTTPRequestOperationManager()
            
            manager.responseSerializer = AFJSONResponseSerializer(readingOptions: NSJSONReadingOptions.AllowFragments) as AFJSONResponseSerializer
            
            manager.requestSerializer = AFJSONRequestSerializer() as AFJSONRequestSerializer
            
            manager.responseSerializer.acceptableContentTypes = NSSet(objects:"application/json", "text/html", "text/plain", "text/json", "text/javascript", "audio/wav") as Set<NSObject>

Answer 3

The url you use (http://www.fr20.wearedesigners.net/WADMac/tourism/fetchGuideListAndroid.php ) returns a not accepted content-type header, instead of text/html it should return application/json.

Answer 4

As Otanaught says, the url you use (http://www.fr20.wearedesigners.net/WADMac/tourism/fetchGuideListAndroid.php ) returns a not accepted content-type header, instead of text/html it should return application/json.

If you have access to the PHP Web Service file, put this before any display code:

header('Content-type: application/json');

Answer 5

If u r using afnetwork 2.6.3 then Simply go to Serilization -> AFURLResponseSerialization.m, line 224, and change it to:

self.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html", nil];

it will work you.
