在我的目标C代码中，我尝试访问SOAP Web服务，但收到以下错误提示：“线程1：EXC_BAD_ACCESS（Code = EXC_I386_GPFLT）”。

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"

在我的 iOSswift 3.0应用程序中，我UIAlertController在当前的 ViewController 上显示了工作表实例。但是，当我在工作表的某个区域（变暗的半透明背景）之外点击时，我不想关闭该工作表，因为我已经必须取消一个操作。任何的想法？

我有带有更多按钮的 MGSwipeTableViewCell。当用户单击“更多”按钮时，将执行以下代码。

func onClickMore(for vmCell: VmCell) {
    let sheet = UIAlertController(title: vmCell.vmItem?.vmNameWithoutIp, message: vmCell.vmItem?.ipAddress, preferredStyle: .actionSheet)

    sheet.addAction(UIAlertAction(title: "Create Ticket", style: .default) { (action: UIAlertAction) in

    })

    sheet.addAction(UIAlertAction(title: "Start VM", style: .default) { (action: UIAlertAction) in

    })

    sheet.addAction(UIAlertAction(title: "Restart VM", style: .default) { (action: UIAlertAction) in

    })

    sheet.addAction(UIAlertAction(title: "Stop VM", style: .destructive) { (action: UIAlertAction) in

    })

    sheet.addAction(UIAlertAction(title: "Cancel", style: .cancel) { (action: UIAlertAction) in

    })

    present(sheet, animated: true) { 
        sheet.view.superview?.addGestureRecognizer(UITapGestureRecognizer(target: self, …
