我想通过FTP上传图片到服务器。
我发现了一个SimpleFTPSample苹果文档中，并下载它。
当运行应用程序（我使用的Xcode 4.5.2，针对iphone 5.0模拟器），它工作正常。 我想通过这个应用创建在我的服务器目录和成功。
但是，在上传应用程序提供的图像时，会导致“开流错误”。 我没有做应用程序的任何变化。 刚输入的网址，用户名和密码。 我觉得没有问题，这一点，因为，这是我所指定的目录中创建成功。
在创建目录的URL是“ftp://54.xyz/newfolder/”这是创建成功。
但是，尽管上传的网址为“ftp://54.xyz/TestImage1.png”
文件路径为“/var/folders/pn/8p0jc4qn70v37j58c1kwf8l80000gn/T/TestImage1.png”
URL通过附加的最后一个组件串与我指定的FTP URL了。
那么，什么是它的错？
在FN，
- (void)stream:(NSStream *)aStream handleEvent:(NSStreamEvent)eventCode
{
case NSStreamEventErrorOccurred: {
[self stopSendWithStatus:@"Stream open error"];
} break;
被称为和显示的流打开错误。
我GOOGLE了一整天，没有需要的结果。 它非常紧迫，我甚至无法启动的赏金这一点。 请帮忙

我有同样的问题。
这是每个托管服务提供商。 我认为这个问题是代码可能过得去的登录名的“@”符号= dev@atoz.com困惑？
您使用的用户名与@唱歌吗？
加入这一行设定PutController.m StartSend中的NetworkStream委托之前固定的问题对我来说：
[self.networkStream setProperty:(id)kCFBooleanFalse forKey:(id)kCFStreamPropertyFTPUsePassiveMode];
如果没有上面的行（或设置为kCFBooleanTrue代替kCFBooleanFalse财产），我一直有流打开错误。 我只是试图用一个FTP服务器，但它似乎不支持被动模式，显然是默认的。
