Accessing the Arcgis secured url using authentication ios - ios

Question

Here I am trying to access the secured URL using the HTTP authentication. But still the data is coming null.
code:
{
NSURL *url = [NSURL URLWithString:#"http://mysecuredurl.com"];
NSString *userName =#"abc#v.com";
NSString *password =#"12345";
NSError *myError = nil;
NSMutableString *loginString = (NSMutableString*)[#"" stringByAppendingFormat:#"%#:%#", userName, password];
NSLog(#"loginstring=%#",loginString);
NSString *authHeader = [#"Basic " stringByAppendingFormat:#"%#", loginString];
NSLog(#"auth header =%#",authHeader);
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL: url
cachePolicy: NSURLRequestReloadIgnoringCacheData
timeoutInterval: 3];
NSLog(#"request %#",request);
[request addValue:authHeader forHTTPHeaderField:#"Authorization"];
NSURLResponse *response;
NSData *data = [NSURLConnection
sendSynchronousRequest: request
returningResponse: &response
error: &myError];
NSLog(#"data %#",data);
NSLog(#"response %#",response);
NSString *result = [[NSString alloc]initWithData:data
encoding:NSUTF8StringEncoding];
NSLog(#"result = %#",result);
}
Both data and response is null. Please do help me out in this. Is there any changes do I need to do? Thank you.

Your authentication string needs to be base64 encoded. Try -
NSData *userPasswordData = [[NSString stringWithFormat:#"%#:%#", userName, password] dataUsingEncoding:NSUTF8StringEncoding];
NSString *base64EncodedCredential = [userPasswordData base64EncodedStringWithOptions:0];
NSString *authHeader= [NSString stringWithFormat:#"Basic %#", base64EncodedCredential]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL: url
cachePolicy: NSURLRequestReloadIgnoringCacheData
timeoutInterval: 3];
[request addValue:authHeader forHTTPHeaderField:#"Authorization"];
