So i am assuming that no-one got the restart to work?

I do have another question, how would i go about creating a quiz that had images as a part of the question? I want to make something for revision for my students so they look at the image, the question displays below it and there are 4 options to choose from.

If anyone could help me out i would appreciate it, and yes i know the thread is quite old.

Cheers,

All you have to do is call

[Self loadView];

To load the game to start over

Thanks!

Hello All,

Just wondering if anyones knows how use a txt file for the questions instead of an array?

[jumbo0]

What exactly do I need to insert to pick a question randomly?

And If i want to include an image to a specefic question, how do I do that?

+ How do I define how many questions you'll get? For example, each quiz will have 10 questions randomly chosen out of 200 questions...

Thanks!

An answer to the above would really help me too...

[webphone]

- (void)viewDidLoad {
    [super viewDidLoad];
	questionLive = NO;
	restartGame = NO;
	theQuestion.text = @"Welcome to the Quiz Game! Think you're a pretty smart cookie, huh? Well, let's test your knowledge!";
	theScore.text = @"Score:0";
	theLives.text = @"";
	questionNumber = 0;
	myScore = 0;
	myLives = 0;
	[answerOne setTitle:@"Let's Play!" forState:UIControlStateNormal];
	[answerTwo setHidden:YES];
	[answerThree setHidden:YES];
	[answerFour setHidden:YES];
	[self loadQuiz];
}

In the code above, [answerOne setTitle:@"Let's Play!" forState:UIControlStateNormal];

It requires user to click answerOne button and starts the quiz.

How can the quiz display without click that button? When the app starts, first quiz display.

I tried to change it to be:
[answerOne setHidden:YES];

But, it does not work.

How should I fix it?

Secondly, how can it load the quizgame.txt which has non-English words? Does it need any encoding?

I'm trying to convert this tutorial into a maths "Times Tables" quiz.

I was wondering if anyone could lend a hand and explaining how to remove the multiple choice element and replace it with a text box and number pad, generate a times tables question and be able to compare the answer typed with the correct answer.

I was thinking either having
•*list all the times table and answers in a DB?
or
• having the app create the times tables questions and answers as the app is running and store the results in a DB?

Please help this is my University project and I've only got till april 30th.

Sorry entered twice...

I have tried many different things now, and nothing really works for me

First i want to pick a random question out of a lot (100+)
I have tried with some arc4random(), but not really works

	questionNumber = questionNumber + 1;

I dont know how hard it would be to make it remember that question that have been asked (guess that is pretty hard)

Second i want to be able to restart the game, and this [self loadView] doesn't really help.

when i try this:

- (IBAction)buttonOne
{
	if(questionNumber == 0){
		// This means that we are at the startup-state
		// We need to make the other buttons visible, and start the game.
		[answerTwo setHidden:NO];
		[answerThree setHidden:NO];
		[answerFour setHidden:NO];
		[self askQuestion];
	}
	else
	{
		NSInteger theAnswerValue = 1;
		[self checkAnswer:(int)theAnswerValue];
		if(restartGame==YES)
		{

			NSLog(@"meh");
			//RESTART Function here
			
		}
	}
}

I get the log "meh" as a answer the last question and not when i press the restart button, very odd.

Hope someone can help, since this is a great tutorial, but needs the last method (restart please).

I've tried [Self loadView]; and it still continues to crash!

What am i doing wrong, sorry for been such a noob!

[Drudoo]

Im trying to make it choose a random number out of a lot of questions. The arc4random() method wont work cus i needs to be number 1 or 7 or 14 or 21 or 28 and so on. Is there a way to make it only choose between those numbers?

Hi, yes I did it with the arc4random() , just use it and % to the number of questions you have , and then multiply that number for the numbers of row to "jump" , 6 in this case, because you have 1 question at each 6 rows

it worked great for me

I have my quiz app almost ready!

[jnce]

Does someone have this working when it's loading from a text file? The code in the first post was deprecated. I've since fixed it to be 4.0 compatible, but I'm getting an NSRangeException when I load in the text file.

Got the reset working
All you have to do is copy the new update score method just the last few line before the else are changed. Then add the

-(void)reset;

to the Quiz game view controller.h file and finally add the reset method below to the Quiz game view controller.m file. There you go a working reset!!

-(void)updateScore
{
	// If the score is being updated, the question is not live
	questionLive = NO;
	
	[timer invalidate];
	
	// Hide the answers from the previous question
	[answerOne setHidden:YES];
	[answerTwo setHidden:YES];
	[answerThree setHidden:YES];
	[answerFour setHidden:YES];
	NSString *scoreUpdate = [[NSString alloc] initWithFormat:@"Score: %d", myScore];
	theScore.text = scoreUpdate;
	[scoreUpdate release];
	
	// END THE GAME.
	NSInteger endOfQuiz = [theQuiz count];
	if((((questionNumber - 1) * 6) + 6) == endOfQuiz)
	{
		// Game is over.
		if(myScore > 0)
		{
			NSString *finishingStatement = [[NSString alloc] initWithFormat:@"That's game!\nNice going \nYou scored %i!", myScore];
			theQuestion.text = finishingStatement;
			[finishingStatement release];
		}
		else
		{
			NSString *finishingStatement = [[NSString alloc] initWithFormat:@"That's game!\nWow. You're terrible! \nYou scored %i.", myScore];
			theQuestion.text = finishingStatement;
			[finishingStatement release];
		}
		theLives.text = @"";
		
		// Make button 1 appear as a reset game button
		restartGame = YES;
		[answerOne setHidden:NO];
		[answerOne addTarget:self action:@selector(reset)forControlEvents:UIControlEventTouchDown];
		[answerOne setTitle:@"Restart the game" forState:UIControlStateNormal];
		

		
		
		
	}
	else
	{
	// Give a short rest between questions
	time = 3.0;
	
	// Initialize the timer
	timer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(countDown) userInfo:nil repeats:YES];
	}
}

// RESET METHOD
-(void)reset {
	
	[self viewDidLoad];	
	
	
}

Hey, bit of a bump but oh well.

Did anyone get the arc4random working? If they did can they post up their code as it is confusing me way too much.

Currently have got the quiz working well but need this random feature to draw in 10 questions from a list of 50 or more.

You screwed up this part

		
		// Make button 1 appear as a reset game button
		restartGame = YES;
		[answerOne setHidden:NO];
		[answerOne addTarget:self action:@selector(reset)forControlEvents:UIControlEventTouchDown];
		[answerOne setTitle:@"Restart the game" forState:UIControlStateNormal];

I'm having trouble with this. I followed the link, but am not understanding it. Does anyone have any better documentation (doesn't have to be the exact code) but just notes on how to implement the random questions from the array?

[tobban2]

in -(void)loadQuiz - xxxViewController.m

Before:

PHP Code:

NSString *fileContents = [NSString stringWithContentsOfFile:textFilePath]; 


after:

PHP Code:

    NSString *fileContents = [NSString stringWithContentsOfFile:textFilePath encoding:NSUTF8StringEncoding error:nil];
    [NSString stringWithContentsOfFile:textFilePath encoding:NSUTF8StringEncoding error:nil]; 


To make it import ex åöä etc.

How many questions do you have? With under 3 questions it freezes for me. With 3 or over it works. But cant get reset to work.
