iOS ASIHTTPRequest [请求临时文件下载路径];会自动下载文件并删除吗？
我正在尝试通过下载一些图像文件来检查响应时间。 所以我使用 ASIHTTPRequest [请求临时文件下载路径];
它会下载iPhone临时目录中的文件并自动删除它吗？
I am trying to check the response time with downloading some image file..
So I am using ASIHTTPRequest [request temporaryFileDownloadPath];
Will it download file in temp directory in iPhone and erase it automatically?

temporaryFileDownloadPath是下载期间放置文件的位置。下载后，它将从那里复制到downloadDestinationPath的位置。如果您将downloadDestinationPath设置为NSTemporaryDirectory()，那么该文件将在某个时候被系统自动删除。如果您想立即删除文件，只需不要设置
downloadDestinationPath或temporaryFileDownloadPath，它将保留在内存中，然后在请求发出时释放超出范围。如果图像太大而无法放入内存，请在某处设置一个downloadDestinationPath（这并不重要，只要它有效），然后在下载完成后使用 <代码>[[NSFileManager defaultManager]removeItemAtPath:[请求downloadDestinationPath]错误：nil]。向error参数传入一个NSError*来检查删除是否遇到错误。The
temporaryFileDownloadPathis where the file is placed during the download. After the download, it will be copied from there to the location ofdownloadDestinationPath. If you setdownloadDestinationPathtoNSTemporaryDirectory(), then the file will be erased by the system automatically at some point.If you want to erase the file straight away though, just don't set a
downloadDestinationPathor atemporaryFileDownloadPath, and it will be kept in memory and then deallocated when the request goes out of scope. If the image is too big to fit in memory, set adownloadDestinationPathsomewhere (doesn't really matter, as long as it's valid), and then after the download is finished remove the file from disk using[[NSFileManager defaultManager] removeItemAtPath:[request downloadDestinationPath] error:nil]. Pass in anNSError*to theerrorparameter to check if the delete encounters an error.
