I want to use CFStreamCreatePairWithSocketToHost
with NSInput
- and OutputStream
s. I have two ivars NSInputStream *_inputStream
and NSOutputStream *_outputStream
.
The following gives me two error messages:
CFStreamCreatePairWithSocketToHost(NULL,
(__bridge_retained CFStringRef)self.hostname, self.port,
(CFReadStreamRef *)&_inputStream, (CFWriteStreamRef *)&_outputStream);
error: cast of an indirect pointer to an Objective-C pointer to '
CFReadStreamRef *
' (aka 'struct __CFReadStream **
') is disallowed with ARC
error: cast of an indirect pointer to an Objective-C pointer to 'CFWriteStreamRef *
' (aka 'struct __CFWriteStream **
') is disallowed with ARC
How would I fix this? I tried using __bridge
but I got similar error messages.
Pass a pointer to actual CFReadStreamRef
and CFWriteStreamRef
variables, then cast when assigning to your NSTypes. Basically:
CFThingRef cfThing = NULL;
CFFunctionGetThing(&cfThing);
NSThing * nsThing = cfThing;
Of course, you'll have to add the appropriate bridge cast and do all appropriate reference count ops for cfThing
.
