如何在ios中的ftp服务器上上载.png或.jpg图像。？

我想从iOS应用程序上传或保存图像到FTP服务器。但是每次我收到错误，ftp未连接

我使用SCRFTPRequest库

这是我的密码

UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
NSData * imageData = UIImagePNGRepresentation(image);
NSFileManager * fileManager = [NSFileManager defaultManager];
NSArray * paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString * documentsDirectory = [paths objectAtIndex:0];
NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.png",image]];
[fileManager createFileAtPath:fullPath contents:imageData attributes:nil];
NSLog(@"image saved");
[picker dismissViewControllerAnimated:YES completion:nil];

ftpRequest = [SCRFTPRequest requestWithURL:[NSURL URLWithString:@"ftp://myURL"] toUploadFile:fullPath];
ftpRequest.username = @"DemoUser";
ftpRequest.password = @"DemoUser";
ftpRequest.customUploadFileName = @"inapp";
ftpRequest.delegate = self;
[ftpRequest startAsynchronous];

从

只需拖放

WhiteRaccoon.h

和

WhiteRaccoon.m

文件，然后在项目中导入

CFNetwork

框架

- (void) upload
    {

        //the upload request needs the input data to be NSData 
        //so we first convert the image to NSData
        UIImage * ourImage = [UIImage imageNamed:@"space.jpg"];
        NSData * ourImageData = UIImageJPEGRepresentation(ourImage, 100);


        //we create the upload request
        //we don't autorelease the object so that it will be around when the callback gets called
        //this is not a good practice, in real life development you should use a retain property to store a reference to the request
        WRRequestUpload * uploadImage = [[WRRequestUpload alloc] init];
        uploadImage.delegate = self;

        //for anonymous login just leave the username and password nil
        uploadImage.hostname = @"xxx.xxx.xxx.xxx";
        uploadImage.username = @"myuser";
        uploadImage.password = @"mypass";

        //we set our data
        uploadImage.sentData = ourImageData;

        //the path needs to be absolute to the FTP root folder.
        //full URL would be ftp://xxx.xxx.xxx.xxx/space.jpg
        uploadImage.path = @"/space.jpg";

        //we start the request
        [uploadImage start];

    }

    -(void) requestCompleted:(WRRequest *) request{

        //called if 'request' is completed successfully
        NSLog(@"%@ completed!", request);

    }

    -(void) requestFailed:(WRRequest *) request{

        //called after 'request' ends in error
        //we can print the error message
        NSLog(@"%@", request.error.message);

    }

    -(BOOL) shouldOverwriteFileWithRequest:(WRRequest *)request {

        //if the file (ftp://xxx.xxx.xxx.xxx/space.jpg) is already on the FTP server,the delegate is asked if the file should be overwritten 
        //'request' is the request that intended to create the file
        return YES;

    }

最后，我成功地将图像文件上传到ftp服务器上

为了在ftp上上传图像，我使用了金浣熊外部库。有了这个库，您可以轻松地将图像上传到ftp服务器

你可以使用它。@HimanshuJoshi在你的链接中有一个php链接需要指定，但我不知道，请帮助我解决。尝试使用白浣熊我不知道

CFUrl

你能给我完整的代码plz吗，因为我是ios新手。它抛出未知错误。。和委托方法未调用。是否已在文件

WebRequestDelegate

中添加协议。查看我的完整答案是的，我添加了它，但它抛出[WRRequestListDirectory stream:handleEvent:[Line 968]未知错误！以及如何写url路径和我的地址，现在我想把图片保存在这里。怎么写。什么是主机名，什么是路径。/很好的链接。这真的帮助我摆脱了在FTP上保存图像的大问题。thanx.@RamaniAshish支持后台上传，这意味着整个应用程序进入后台模式，正常情况下，除了NSURLSERSESSION之外，所有执行都将停止，这有效吗？
