Q:

I'm trying to send requests to servers

NSString *url =[NSString stringWithFormat:@"http://cvidyasharam.physicscafe.in/loginmobile.php?email=%@ password=%@",Username.text,Password.text];
equest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:10.0];
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if (conn)
{
    NSURLResponse *response;
    NSError *err;
   responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];

}

if  ([responseData isEqual:@"yes"]){
    [self performSegueWithIdentifier:@"condition" sender:nil];
    login = @1;
}
else{
    UIAlertView *alert= [[UIAlertView alloc]initWithTitle:@"Incorrect combo" message:@"Intruder alert" delegate:self cancelButtonTitle:@"cancel" otherButtonTitles: nil];
    [alert show];

Every time I run the program it ends with the screen highlighting the  responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err]; line in green.
Is anything wrong with the code?

A:

What @HotLicks said is true. 
The application has stopped on a break point.  
My statement based on the images you provided here. Take a closer look.

It clearly shows that the execution has been paused.  See if you have something like this on that particular line.
