ios - 得到错误:“线程1:SOAP请求期间EXC_BAD_ACCESS(Code = EXC_I386_GPFLT)

Question

在我的 objective-c 代码中，我尝试访问SOAP Web服务，但由于错误而报错:“线程1:EXC_BAD_ACCESS(Code = EXC_I386_GPFLT)” 在下一行附近。

NSString *httpBodySoapMsg = [NSString stringWithFormat:
                                     @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"......
                                     "</x:Envelope>\n", _encryptedUsername,_encryptedPassword, nonce, digest];

下面是我的完整代码。

#pragma mark - login request method

- (void)sendValidateEmailRequest {
    NSString *nonce = [NSString stringWithFormat:@"%ld", (long)(NSTimeInterval)([[NSDate date] timeIntervalSince1970])];
    NSString *digest = [Utils sha1:[NSString stringWithFormat:@"%@%@%@", _textUsername.text, nonce, _textPassword]];    // input is forsha
    NSString *httpBodySoapMsg = [NSString stringWithFormat:
                                 @"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
                                 "<x:Envelope xmlns:x=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:mob=\"https://billing.eukhost.com/webservices/mobile_service_new?wsdl\">\n"
                                 "<x:Header/>\n"

                                 "</x:Body>\n"
                                 "</x:Envelope>\n", _encryptedUsername, _encryptedPassword, nonce, digest];

    NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:DEMO_URL]];
    [urlRequest setValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [urlRequest setValue:[NSString stringWithFormat:@"%@%@", DEMO_URL, VALIDATE_EMAIL] forHTTPHeaderField:@"SOAPAction"];
    [urlRequest setValue:@"Basic YjBlMDc2ZjAxZjFjZjAyODc6ODQ0NzI0ZGMyYjMwNWM4MzA=" forHTTPHeaderField:@"Authorization"];
    [urlRequest setValue:_encryptedUsername forHTTPHeaderField:@"PHP_AUTH_USER"];
    [urlRequest setValue:_encryptedPassword forHTTPHeaderField:@"PHP_AUTH_PW"];

    NSString* deviceId = [[[UIDevice currentDevice] identifierForVendor] UUIDString]; // IOS 6+
    [urlRequest setValue:deviceId forHTTPHeaderField:@"PHP_AUTH_DEVICE"];
    // @"96c6754c9dc3b654517c5"

    NSString *msgLength = [NSString stringWithFormat:@"%ld", (long)(httpBodySoapMsg.length)];
    [urlRequest setValue:msgLength forHTTPHeaderField:@"Content-Length"];

    [urlRequest setHTTPMethod:@"POST"];
    [urlRequest setHTTPBody:[httpBodySoapMsg dataUsingEncoding:NSUTF8StringEncoding]];

    RestApi *restApi = [RestApi sharedManager];
    restApi.delegate = self;
    [restApi httpRequest:urlRequest withResponseId:VALIDATE_EMAIL_ID];
}

将属性声明为strong而不是assign

@property (strong, nonatomic) NSString *encryptedUsername;
@property (strong, nonatomic) NSString *encryptedPassword;
