Streaming iPhone Programming (CFStream) Hello World

Question

I am currently trying to send Hello World from my iPhone to a remote computer running a production server (telnet tested on iPhone).

Here is my code:

#import "client.h"

@implementation client

- (client*) client:init {
 self = [super init];
 [self connect];
 return self;
}

- (void)connect {
        CFWriteStreamRef writeStream;
        CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)[NSString stringWithFormat: @"192.168.1.1"], 50007, NULL, &writeStream);
  NSLog(@"Creating and opening NSOutputStream...");
  oStream = (NSOutputStream *)writeStream;
  [oStream setDelegate:self];
  [oStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
  [oStream open];
}

- (void)stream:(NSStream *)stream handleEvent:(NSStreamEvent)eventCode {
    NSLog(@"stream:handleEvent: is invoked...");

    switch(eventCode) {
        case NSStreamEventHasSpaceAvailable:
        {
            if (stream == oStream) {
                NSString * str = [NSString stringWithFormat: @"Hello World"];
                const uint8_t * rawstring =
    (const uint8_t *)[str UTF8String];
                [oStream write:rawstring maxLength:strlen(rawstring)];
                [oStream close];
            }
            break;
        }
    }
}

@end

For customer .h:

#import <UIKit/UIKit.h>


@interface client : NSObject {
 NSOutputStream *oStream;
}

-(void)connect;

@end

Finally, in AppDelegate.m:

- (void)applicationDidFinishLaunching:(UIApplication *)application {    

    // Override point for customization after app launch    
    [window addSubview:viewController.view];
 [window makeKeyAndVisible];
 [client new];
}

Does anyone have an idea of ​​what is going wrong?

. init client:, , ( - id int - , id, ) init. () , . :

- (id)init
{
  if( (self = [super init]) ) {
   [self connect];
  }
  return self;
}

, [Client new], connect . , Objective-C/Cocoa.
