Json Response:

{"error":"Line 1.\\nLine 2."}

Code

[self setLastError:[dictJsonResult jsonObjectForKey:@"error"]];

UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:@"Registration Failed"
    message:[ParseHelper lastError] delegate:nil
    cancelButtonTitle:@"OK"
    otherButtonTitles:nil] autorelease];

Answer 1

So Ismael already explained what’s wrong; I tell you how to fix it:

[self setLastError:[[dictJsonResult jsonObjectForKey:@"error"]
    stringByReplacingOccurrencesOfString:@"\\n" withString:@"\n"]];
