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.
