西班牙人的角色不能正常看到ios

Question

NSString *urlString = GET_EVENTLIST_URL_STRING;
    NSURL *url = [NSURL URLWithString:[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

    if (!url)
    {
        NSString *reason = [NSString stringWithFormat:@"Could not create URL from string %@", GET_EVENTLIST_URL_STRING];
        [self.delegate didGetEventListInCorrect:reason];
        return;
    }

    // Create a mutable request because we will append data to it.
    theRequest = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval: 30.0];

    // Set the HTTP method of the request to POST
    [theRequest setHTTPMethod:@"POST"];




    if (!theRequest)
    {
        NSString *reason = [NSString stringWithFormat:@"Could not create URL request from string %@", GET_EVENTLIST_URL_STRING];
        [self.delegate didGetEventListInCorrect:reason];
        return;
    }
    theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

===== 大家好， 我有这个代码，这是我的字符串“EventoPúblico”，但我在输出中看到“úblico”。我也使用了NSUTF8StringEncoding但我无法管理这个？有什么想法吗？提前谢谢。
