USe the below function of NSString.

- (NSRange)rangeOfString:(NSString *)aString

The above function will not check for the equality, it will tell u whether your responseStr contain "nok" string OR not ..

    NSRange myStringRange = [responseStr rangeOfString:@"nok"] ;
    if(myStringRange.location != NSNotFound )
    {
      NSLog(@"Hiii");
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"" message:@"Attenzione: si è v      erificato un errore di richiesta del premio." delegate:self cancelButtonTitle:nil  otherButtonTitles:@"OK", nil];
    [alert show];
    [alert release];
     }
  else {
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"" message:@"Inviato con successo" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
    [alert show];
    [alert release];
    [self startIscrivity2View];

       }

    }

Try:

if([responseStr isEqualToString: @"nok"])
{
   ...
}

---

Try replacing

responseStr == @"nok"

with

[responseStr isEqualToString:@"nok"];

In your code, the variable is not checking if the characters in the string are the same, it is checking if they are pointing to the same location in memory.

---

Try isEqualToString

if([responseStr isEqualToString:@"nok"]){

}

or compare

if([responseStr compare:@"nok"] == NSOrderedSame){

}

Never compare 2 strings using == operator.

---

Try.

if([responseStr isEqualToString: @"{\"nok\"}"] == TRUE)
{
 ....
}
else
{
  .....
}

Or you can remove all exara characters from response string and then compair it.

Like -

NSString *str = [responseStr stringByReplacingOccurrencesOfString:@"{" withString:responseStr];

str = [responseStr stringByReplacingOccurrencesOfString:@"}" withString:responseStr];
str = [responseStr stringByReplacingOccurrencesOfString:@"\"" withString:responseStr];

if([responseStr isEqualToString: @"nok"] == TRUE)
{
     ....
}
else
{
      .....
}

Or you can try.

NSRange myStringRange = [responseStr rangeOfString:@"nok"] ;
if(myStringRange.location != NSNotFound )
{
  ...
}
else
{
  ...
}
