NSLog(temp);




// create our stream
NSOutputStream *outputStream =
[[NSOutputStream alloc] initToFileAtPath:temp append:YES];

[[S3GetObjectRequest alloc] initWithKey:self.objectName
withBucket:self.bucket];
getObjectRequest.outputStream = outputStream;

Answer 1

您将需要使用NSSearchPathForDirectoriesInDomains来获取应用程序的文档目录并使用它来构建文件路径和名称。

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,     NSUserDomainMask, YES);
    NSString *documentPath = [paths objectAtIndex:0];
