我正在尝试将我的应用移植到iOS5。我通过CFSockets使用TCP连接到服务器。我现在的问题是从CFReadStreamRef到NSInputStream的转换(强制转换)(与write相同)。使用iOS4,我可以使用免费桥接,但是使用iOS5的自动引用计数,这是不可能的。这就是我得到的:
error: Automatic Reference Counting Issue: Cast to 'NSInputStream *' of a non-Objective-C to an Objective-C pointer is disallowed with Automatic Reference Counting
代码:
CFReadStreamRef readStream;
CFWriteStreamRef writeStream;
CFStringRef strRef = CFStringCreateWithCString(NULL,
[urlStr UTF8String],
NSUTF8StringEncoding);
CFStreamCreatePairWithSocketToHost(NULL,
strRef,
4444,
&readStream,
&writeStream);
NSInputStream *iStream = (NSInputStream *)readStream;
NSOutputStream *oStream = (NSOutputStream *)writeStream;
是否有另一种方法可以将套接字输出/输入NSStream? 谢谢你的提示!

管理免费电话桥接非常清楚地表明您应该使用以下内容:
NSInputStream *iStream = objc_unretainedObject(readStream);
