I am getting the following exception when adding an xml body to a POST request. I get the same exception when doing the same with GET. Any help would be appreciated.
- (IBAction)buttonTapped:(id)sender {
NSLog(@"buttonTapped");
//Creating the request
NSMutableURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://192.168.0.1:9081/Transport/services/DriverService"] cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval: 30.0];
[ request setHTTPMethod: @"POST"];
//creating connection and sending it
NSURLConnection *connection = [ [NSURLConnection alloc] initWithRequest:request delegate:self];
NSString *xmlString = @"<Driver type=\"GetName\"><DriverID>1</DriverID></Driver>";
[request setHTTPBody:[xmlString
dataUsingEncoding:NSUTF8StringEncoding]];
//checking if connection is good
if (connection){
NSLog (@"Connection successfull!");
self.responseData = [NSMutableData data];
}
else
{
NSLog (@"Connection failed");
}
}
Exception:

NSMutableURLRequest *request = [NSURLRequest requestWithURL:...
should be
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:...
Although you declare request to have NSMutableURLRequest
type, you create an instance of NSURLRequest
class, which does not responds to -setHTTPMethod:
selector.
