ASIHTTPRequestErrorDomain 代码=8。无法将文件从临时目录移动到文档

我使用 ASIHTTPReqeust 下载文件。一切都下载正常，但无法将文件从临时目录移动到文档。当我实现

-(void) request:(ASIHTTPRequest *)request didReceiveData:(NSData *)data

请求失败并出现错误时。但文件已下载。

如果我删除此实现，一切都很好，并且文件将移至文档。这是错误文本：

Error Domain=ASIHTTPRequestErrorDomain Code=8 "Failed to move file from '/var/folders/Qu/Qu0o0VcpEY4npJr2C1yPzE+++TI/-Tmp-/Skrillex feat.

谁遇到过类似的问题？

原文

I download files with ASIHTTPReqeust. Everything downloads fine but it can't move file from temp directory to documents. When i implement

-(void) request:(ASIHTTPRequest *)request didReceiveData:(NSData *)data

request fails with an error. But file is downloaded.

If i remove this implementation, everything is fine, and files are moving to docs.
Here is Error text:

Error Domain=ASIHTTPRequestErrorDomain Code=8 "Failed to move file from '/var/folders/Qu/Qu0o0VcpEY4npJr2C1yPzE+++TI/-Tmp-/Skrillex feat.

经常让人们感到困惑的是，您必须自己创建要下载的目录（ASIHTTPRequest 不会自动创建它）。

然而，鉴于您说它与实现 didReceiveData 有关，但事实并非如此。

如果您查看 ASIHTTPRequest.m，您会发现如果您在委托中实现“didReceiveData”，则会看到它设置“dataWillBeHandledExternally” - 这将阻止数据写入磁盘。您可以自己编写数据，也可以更改 ASIHTTPRequest.m 代码以添加一个标志以强制它也在内部处理数据。

我遇到了同样的错误，但原因不同。我将发布我的问题 - 以防万一其他人也有类似的情况。

我试图在保存新图像之前删除旧图像。

NSString *mImgName = [managedObj valueForKey:@"aImgName"];

NSString * mFilePath = [[self applicationDocumentsDirectory] 
                stringByAppendingPathComponent:mImgName];

if ([mFileManager fileExistsAtPath:mFilePath]) 
{
    [mFileManager removeItemAtPath:mFilePath error:nil];
}

问题是 - 如果 mImgName 为零，mFileManager 将删除整个目录。

通过添加额外的检查 nil 或太短的 mImgName 值，它解决了问题。

希望它能对某人有所帮助！

I encountered same error, but the reason was different. I will post my problem - just in case anyone else has similar situation.

I was trying to delete old images, before saving new ones.

NSString *mImgName = [managedObj valueForKey:@"aImgName"];

NSString * mFilePath = [[self applicationDocumentsDirectory] 
                stringByAppendingPathComponent:mImgName];

if ([mFileManager fileExistsAtPath:mFilePath]) 
{
    [mFileManager removeItemAtPath:mFilePath error:nil];
}

Problem was - in case mImgName is nil, mFileManager will delete whole directory.

By adding extra checking for nil or too short mImgName value, it solved problem.

Hopefully it will help someone!
