Question

I want to establish socket connection to streaming server (with iphone ) and want to download its content like image,.css,etc to iphone. Any Idea or sample code is can help me. I need to write code for client only.

Answer 1

Establish Connection as follows and change the urlStr to your server URL
NSString *urlStr = #"http://192.168.0.108";
NSURL *website = [NSURL URLWithString:urlStr];
CFReadStreamRef readStream;
CFWriteStreamRef writeStream;
CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)[website host], 1234, &readStream, &writeStream);
NSInputStream *inputStream = (NSInputStream *)readStream;
NSOutputStream *outputStream = (NSOutputStream *)writeStream;
[inputStream setDelegate:self];
[outputStream setDelegate:self];
[inputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[outputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[inputStream open];
[outputStream open];
Make Use of NSStream Delegate as follows to read data
- (void)stream:(NSStream *)stream handleEvent:(NSStreamEvent)eventCode {
switch(eventCode) {
case NSStreamEventHasBytesAvailable:
{
NSLog(#"Bytes Available");
uint8_t b[1024];
unsigned int len = 0;
NSMutableData *data = [[NSMutableData alloc] init];
len = [(NSInputStream *)stream read:b maxLength:1024];
if(!len) {
if ([stream streamStatus] != NSStreamStatusAtEnd)
{
}
} else {
[data appendBytes:(const void *)b length:len];
int bytesRead;
bytesRead += len;
//make use of data here
}
}
break;
}
}

Slightly changes in the code I used:
NSHost *host = [NSHost hostWithName:[website host]];
[NSStream getStreamsToHost:host
port:8766
inputStream:iStream
outputStream:oStream];
Instead of
CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)[website host], 1234, &readStream, &writeStream);
NSInputStream *inputStream = (NSInputStream *)readStream;
NSOutputStream *outputStream = (NSOutputStream *)writeStream;
