How To Read A Remote Text File

- by XcodeDev

Hi, I would like to read a remote text file called posts.txt on my website. An example of the insides of the posts.txt file would be this: <div style="width : 300px; position : relative">2 scored by iSDK <img src="Bar.png" /></div><div style="width : 300px; position : relative">2 scored by martin <img src="Bar.png" /></div> What I wanted to know is how can I get the score, and scored by text from the .txt file? The score is (in this case) the: 2, and the scored by text in this case would be: "scored by iSDK". Any code telling me how to do this is twice as helpful! Thanks in advanced XcodeDev

Getting random objects from an array, and if the objects are the same, get a new object.

- by XcodeDev

Hi, I have made a jokes application, where the user generates a joke and the joke will display in a UILabel. However I am trying to randomise the jokes show, but I do not want to show the same joke twice. Please could you tell me how I could do this. I am using the code below to try and do that, but it seems that it is not working. - (IBAction)generateNewJoke { if (i < [jokeArray count]) { i++; [userDefaults setInteger:[userDefaults integerForKey:kNewIndex] forKey:kOldIndex]; int oldnumber = [userDefaults integerForKey:kOldIndex]; int newnumber = [userDefaults integerForKey:kNewIndex]; [answerLabel setText:@""]; [userDefaults setInteger:i forKey:kNewIndex]; if (oldnumber == newnumber) { NSLog(@"they are the same"); [userDefaults setInteger:arc4random()%[jokeArray count] forKey:kNewIndex]; } [jokeLabel setText:[jokeArray objectAtIndex:[userDefaults integerForKey:kNewIndex]]]; } }

TextField Covering UIAlertView's Button.

- by XcodeDev

Hi, I am using a UIAlertView with three buttons: "Dismiss", "Submit Score" and @"View Leaderboard". The UIAlertView also contains a UITextField called username. At the moment the UITextField "username" is covering one of the buttons in the UIAlertView. I just wanted to know how I could stop the UITextField from covering one of the buttons, i.e move the buttons down. Here is an image of what is happening: And here is my code: [username setBackgroundColor:[UIColor whiteColor]]; [username setBorderStyle:UITextBorderStyleRoundRect]; username.backgroundColor = [UIColor clearColor]; username.returnKeyType = UIReturnKeyDone; username.keyboardAppearance = UIKeyboardAppearanceAlert; username.placeholder = @"Enter your name here"; username = [[UITextField alloc] initWithFrame:CGRectMake(20.0, 45.0, 245.0, 25.0)]; username.borderStyle = UITextBorderStyleRoundedRect; [username resignFirstResponder]; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Congratulations" message:[NSString stringWithFormat:@"You tapped %i times in %i seconds!\n", tapAmount, originalCountdownTime] delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:@"Submit To High Score Leaderboard", @"View Leaderboard", nil]; alert.tag = 01; [alert addSubview:username]; [alert show]; [alert release];

Help Redirecting A Page to Another Page with adverts for 5 seconds, and then redirecting to another page.

- by XcodeDev

Hey, I am trying to redirect a page to another page, and that was working successfully. However I am trying to redirect the first page to another page with adverts. This page will then redirect to another page after five seconds. I am trying to do that by doing this: <?php include('ads.php'); ?> <?php sleep(2); $url = $_GET['url']; header("Location: ".$url.""); exit; ?> However it is showing the advert in ads.php perfectly, but it is not redirecting after five seconds. I am receiving this error in my web browser: Warning: Cannot modify header information - headers already sent by (output started at /home/nucleusi/public_html/adverts/ads.php:1) in /home/nucleusi/public_html/adverts/index.php on line 7 A typical link I would be redirecting to would be this: http://nucleusiphone.com/adverts/index.php/?url=http%3A%2F%2Fitunes.apple.com%2Fmx%2Falbum%2Fstill-got-the-blues%2Fid14135178%3Fi%3D14135158 Thanks in advanced. PS. I don't know any php so any code helps!
