NSURLConnection parse issue - ios7

Question

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:SPACEREQUESTFINAL_URL] cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60];
NSString *authStr = [NSString stringWithFormat:#"%#:%#", #"mymac", #"qerty!98"];
NSData *authData = [authStr dataUsingEncoding:NSUTF8StringEncoding];
NSString *authValue = [NSString stringWithFormat:#"Basic %#", [authData base64EncodedString]];
[request setValue:authValue forHTTPHeaderField:#"Authorization"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%d",[data length]] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody:data];
[request setHTTPMethod:#"POST"];
[request setTimeoutInterval:120];
[request setAllHTTPHeaderFields:jsonDictionary];
NSHTTPURLResponse* urlResponse=nil;
NSError *error=nil;
NSData *serverResponse = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error];
NSLog(#"ServerResponse %#",serverResponse);
if (error==nil)
{
[NSURLConnection connectionWithRequest:request delegate:self];
NSString *str1=[[NSString alloc]initWithData:serverResponse encoding:NSUTF8StringEncoding];
NSLog(#"SSTR %#",str1);
NSMutableDictionary *JsonDict=[NSJSONSerialization JSONObjectWithData:serverResponse options:NSJSONReadingAllowFragments error:&error];
}
Data is not parsing
ServerResponse is coming null -- request is not responding to NSURLConnection may be
Please suggest how to resolve it.
Thank you

NSMutableDictionary *datadict=[NSMutableDictionary dictionary];
[datadict setObject:[NSString stringWithFormat:#"%#", mymac] forKey:#"yourkeytoidentify"];
[datadict setObject:[NSString stringWithFormat:#"%#",qerty!98] forKey:#"yourkeytoidentify"];
NSData* jsonData = [NSJSONSerialization dataWithJSONObject:datadict options:kNilOptions error:nil];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
NSURL *someURLSetBefore =[NSURL URLWithString:#" url "];
[request setURL:someURLSetBefore];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
// [request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
// [request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setHTTPBody:jsonData];
NSError *error;
NSURLResponse *response;
NSData *responseData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString * string1=[[NSString alloc]initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(#"%#",string1);
}
