我想将我的应用生成的图像上传到 Dropbox。我从 DBRESTClient 看到了上传方法，但在我看来，我必须在调用上传方法之前将图像写入临时文件。

有没有办法从内存中的对象上传文件？像这样的东西：

UIimage *myImage = [[UIImage alloc]....
//
// Here I create the image on my app
//
NSData *myData = UIImageJPEGRepresentation(myImage, 1.0);
DBRestClient *rc = [[DBRestClient alloc] initWithSession:[DBSession sharedSession]];
self.restClient = rc;
[rc release];
self.restClient.delegate = self;
[self.restClient uploadFile:@"myImage.jpg" toPath:@"DropBoxPath" fromPath:myData];

DBRESTClient 的标头只显示

/* Uploads a file that will be named filename to the given root/path on the server. It will upload
   the contents of the file at sourcePath */
- (void)uploadFile:(NSString*)filename toPath:(NSString*)path fromPath:(NSString *)sourcePath;

iPhone有一个磁盘，所以用给定的方法将你的图像上传为tmp文件然后删除它？为此，您可以使用NSData的writeToFile:atomically:或writeToFile:options:error :。

这就是我实施解决方案的方式：

- (void) uploadToDropBox {
    self.restClient = [[DBRestClient alloc] initWithSession:[DBSession sharedSession]];
    self.restClient.delegate = self;
    [self.restClient createFolder:dropBoxFolder];

    NSString *fileName = @"myImage.png"; 
    NSString *tempDir = NSTemporaryDirectory();
    NSString *imagePath = [tempDir stringByAppendingPathComponent:fileName];

    NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(self.loadQRCodeImage.image)];
    [imageData writeToFile:imagePath atomically:YES];

    [self.restClient uploadFile:fileName toPath:dropBoxFolder fromPath:imagePath];
}
