Where is the rest of the tutorial?

First I have to say this tutorial has been very helpful, Thanks

I have a few questions though.

I have the leaderboard up and running, and I have it also displaying in my app just fine. A few things that Im running into is when the user clicks the leaderboard button in my app I would like to have them enter there username to submit there high score then have the high scores view controller slides up from the bottom and displays on top of the current view.

Im using your Inserting A UITextField In A UIAlertView, to prompt the user to enter there username. Im not sure how to modify this code, so when the user enters there username and clicks the “OK!” button that it then submits the username and highscore to the leaderbord and closes the UIAlertView and opens the high scores view. And in turn if the user clicks the “Dismiss” button it closes the UIAlertView and opens the high scores view without submitting a score or name.

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@”Enter A Username Here” message:@”this gets covered!” delegate:self cancelButtonTitle:@”Dismiss” otherButtonTitles:@”OK!”, nil];

UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12, 45, 260, 25)];

CGAffineTransform myTransform = CGAffineTransformMakeTranslation(0, 60);

[alert setTransform:myTransform];

[myTextField setBackgroundColor:[UIColor whiteColor]];

[alert addSubview:myTextField];

[alert show];

[alert release];

[myTextField release];

The other issue I noticed, is there is nothing stopping someone from submitting multiple high scores, and flooding the leaderboard with just there name and scoe ten times. Is there another “possible simple” PHP script that when submitting a score it does some sort of check, such as checking if the users UDID and username match, and if there score was greater than the one currently on/or in the database then allow them to post it, if not display an alert, or just “Dismiss” the submission and display the high score view.

I know this is asking allot, any help would be great.

Thanks again.

Thanks

HighScoresView * hsv = [[HighScoresView alloc] initWithNibName:@”HighScoresView”
bundle:[NSBundle mainBundle]];
[self presentModalViewController:hsv animated:YES];
[hsv release];

The error would say that HighScoresView was undeclared, after a while I got the error to go away. Then I was getting hsv is undeclared and fixed that by adding Controller to the end of each HighScoresView. I was then getting a bad execution error. It seems (I traced through the debugger) that it is not taking the string from my textBox.text (Debugger says it is not a valid CFString. Then when it goes to encode the username it does the same thing and crashes. Do you have any suggestions on how I can fix this? I’ve been puzzle by it for hours now.

Also, if I want to limit the maximum number of entries in the table, how should I modify the code?

Thanks a lot!

https://developer.apple.com/iphone/library/samplecode/Reachability/index.html

Usage:

Reachability* reachability = [Reachability sharedReachability];
[reachability setHostName:@"www.example.com"]; // set your host name here
NetworkStatus remoteHostStatus = [reachability remoteHostStatus];

if(remoteHostStatus == NotReachable) { }
else if (remoteHostStatus == ReachableViaWiFiNetwork) { }
else if (remoteHostStatus == ReachableViaCarrierDataNetwork) { }

I build the tutorial but it doesn’t work.

Tnx in advance.

@Marin – I have never had any issues with FLOAT. But I’m sure you could easily switch it out with DOUBLE. As far as teh POST goes, there are many ways security could be improved. HTTP Basic AUTH would be another way to prevent attacks. I didn’t really want to go too much into it in this tutorial as I wanted to keep things simple and show users how to get a leaderboard up with very little code. Thanks for the suggestion.

For the MySQL,based on my experience I never use FLOAT column type, because I had huge problems with float math on it, I always use DOUBLE instead, which seems to work better.

Also, wouldn’t it be better if the password was sent trough a POST request? Or it was too much code overhead for the simple tutorial ?

Anyhow, I’m always waiting for the new post on your blog, and congrats once more

Marin
