After initiating a connection (getStreamsToHost) I don't get an
event that the input stream has bytes available, if I check it, it
returns NO but if I go ahead and read it anyway, I get the usual
banner.
It sounds like you didn't call -scheduleInRunLoop:forMode: ?
Covered. See below for full code.
uint8_t *readBuffer;
unsigned int bufferLength;
BOOL gotBuffer = [readStream getBuffer: &readBuffer length:
&bufferLength];
The last line always says arguments 1 and/or 2 are incompatible
pointer type. I've tried every combination of * and &, no luck.
Try declaring bufferLength as NSUInteger, as it's declared in the
docs and header.
D'oh, thanks, that fixed that problem. Still getting strange issues
though with this code:
[NSStream getStreamsToHost: mailHost port: mailPortNumber inputStream:
&readStream outputStream: &writeStream];
mailHost and mailPortNumber are imap.gmail.com and 587 if that matters
Both streams are retained, setDelegate: self, scheduleInRunLoop and
open.
if ([readStream hasBytesAvailable])
NSLog(@"Has Bytes");
else
NSLog(@"No Bytes");
This always returns No Bytes
uint8_t *readBuffer;
NSUInteger bufferLength;
BOOL gotBuffer = [readStream getBuffer: &readBuffer length:
&bufferLength];
gotBuffer always == NO and bufferLength of 0.
int len = [readStream read: readBuffer maxLength: 300];
len always == 0 and the buffer is empty.
NSMutableData *returnMessage = [NSMutableData dataWithLength: 300];
[readStream read: [returnMessage mutableBytes] maxLength: 300];
NSMutableString *readData = [[[NSMutableString alloc] initWithBytes:
[returnMessage bytes] length: 300 encoding: NSUTF8StringEncoding]
autorelease];
NSLog(@"Read: %@", readData);
return readData;
This will always work as expected:
Read: 220 mx.google.com ESMTP...
But only if I don't read from the stream twice. If all of the above
code is run, it fails with "Program received signal:
“EXC_BAD_ACCESS”." If I comment out the int len = [readStream...
section, the NSMutableData section reads fine and gets data.
It's almost is if the NSMutableData is making it up but the docs say
dataWithLength returns a zeroed out object.
