Question

So I have had extensive experience reading rendered html source code of a website in Java. However I have researched thoroughly regarding how to do the exact same thing in Objective-C and have been able to come up with a solution that should work, but it doesn’t.
The idea is that i want to read each line, for example:”view-source:www.apple.com”, i want the read the result of that page line by line. I don’t want any Html parser etc.
This is what i have:

NSString *s = [NSString stringWithFormat:@"http://www.apple.com"];
NSURL *url = [NSURL URLWithString:s];

NSInputStream *iStream= [[NSInputStream alloc] initWithURL:url];

[iStream setDelegate:self];

[iStream scheduleInRunLoop:[NSRunLoop currentRunLoop]
                   forMode:NSDefaultRunLoopMode];

[iStream open];
NSLog(@"stream successfully opened");



NSInteger result;
uint8_t buffer[1024];
    while((result = [iStream read:buffer maxLength:1024]) != 0) {       
    if(result > 0) {
        NSLog(@"Buffer is %@",buffer);

        // buffer contains result bytes of data to be handled
    } else {
        NSLog(@"ERROR: %@",buffer);
        // The stream had an error. You can get an NSError object using [iStream streamError]
    }
    NSLog(@"end of while loop: %@",buffer);

}
// Either the stream ran out of data or there was an error


NSLog(@"Either the stream ran out of data or there was an error");

This runs and compiles fine, but the result is always 0. Again i have done a a lot of research and i don’t understand why the result is 0. Any help is appreciated.

This other solution worked…

NSString *s = [NSString stringWithFormat:@"http://www.apple.com"];
NSURL *url = [NSURL URLWithString:s];


NSData *data = [NSData dataWithContentsOfURL:url];
NSString* newStr = [[NSString alloc] initWithData:data
                                         encoding:NSUTF8StringEncoding];
NSArray *arr= [newStr componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]];

although, i would have rather read the page line by line as this seems inefficient-but i’ll settle with this for now until i can find a better answer.
