运行几分钟后,我的应用程序中的所有动画都消失了,甚至系统动画如警报动画和UINavigationController动画也消失了.可能是什么问题？

PS我不会[UIView setAnimationsEnabled]在任何地方使用.

我有一个简单的Web服务,我想制作一个方法,它将返回一个单一的文本文件.我是这样做的:

    public byte[] GetSampleMethod(string strUserName)
    {
        CloudStorageAccount cloudStorageAccount;
        CloudBlobClient blobClient;
        CloudBlobContainer blobContainer;
        BlobContainerPermissions containerPermissions;
        CloudBlob blob;
        cloudStorageAccount = CloudStorageAccount.DevelopmentStorageAccount;
        blobClient = cloudStorageAccount.CreateCloudBlobClient();
        blobContainer = blobClient.GetContainerReference("linkinpark");
        blobContainer.CreateIfNotExist();
        containerPermissions = new BlobContainerPermissions();
        containerPermissions.PublicAccess = BlobContainerPublicAccessType.Blob;
        blobContainer.SetPermissions(containerPermissions);
        string tmp = strUserName + ".txt";
        blob = blobContainer.GetBlobReference(tmp);
        byte[] result=blob.DownloadByteArray();
        WebOperationContext.Current.OutgoingResponse.Headers.Add("Content-Disposition", "attachment; filename="+strUserName + ".txt");
        WebOperationContext.Current.OutgoingResponse.ContentType = "text/plain";
        WebOperationContext.Current.OutgoingResponse.ContentLength = result.Length;
        return result;
    }

......并从服务界面:

    [OperationContract(Name = "GetSampleMethod")]
    [WebGet(UriTemplate = "Get/{name}")]
    byte[] GetSampleMethod(string name);

它返回一个包含XML响应的测试文件.所以问题是:如何在没有XML序列化的情况下返回文件？
