SampleFTPSample代码中的iOS 6 EXC_BAD_ACCESS

问题描述

我运行从iOS开发人员中心下载的SampleFTPSample源代码（iOS6.0 SDK，Xcode4.5）。

I run the SampleFTPSample source code (iOS6.0 SDK, Xcode4.5)which downloaded from iOS Developer Center.SampleFTPSample

作为图像，当我从ftpServer检索列表时，有时会出现EXC_BAD_ACCESS错误。我没有修改代码，我不知道为什么，我该如何修复它？

as the Images, when I retrieved a list from ftpServer, sometimes will get EXC_BAD_ACCESS error. I have not modified the code, I don't know why, and How can I fixed it?

非常感谢。

推荐答案

通过在创建流后立即将kCFStreamPropertyFTPAttemptPersistentConnection属性设置为false（使用CFReadStreamCreateWithFTPURL）来完成此操作。这可能是这样的：

do this by setting the kCFStreamPropertyFTPAttemptPersistentConnection property to false, immediately after creating the stream (using CFReadStreamCreateWithFTPURL). Here's what that might look like:

 success = [self.networkStream setProperty:(__bridge id) kCFBooleanFalse
    forKey:(__bridge NSString *) kCFStreamPropertyFTPAttemptPersistentConnection
];
assert(success);
