Can two players use the same game app without erasing each other's scores?

Can two players use the same game app on the same device without erasing each other's scores? My two sons build up their characters and progress in their games, then the other one wants to play, erasing the first son's progress.
Is it possible to create two player identities in the Game Center?
Is it possible to have two different Apple User ID accounts on the same device? Is that even desirable?
Many thanks!

You can create as many individual user accounts on a Mac as you like. Then, any one or more of those users can remotely log in from another Mac and use that Mac as their own, simultaneously. Each account will remain separate from all others.
However, since each user needs to have a Mac to do that, I'm not sure how you could effectively double the number of users as you describe.

Can two bands use the same name on iTunes?

Hi, I'm in a band that uses the same name as another band listed on iTunes.
Can two bands with the same name be listed on iTunes? We hope to eventually have an album for sale on the site and I'd like to know now if it's going to be a problem.

Of course it will be a problem. You simply can not have two bands with the same name. I can think of MANY bands that had to change their names (either completely or just for certain countries) because the name was already taken. Blink (Blink-182), Bush (Bush X), The Beat (The English Beat), Yazoo (Yaz), and the list goes on and on.
Your band better start brain storming for a new or modified name.

Can multiple accounts use the same purchased apps from the same computer?

Hope one of you guys can help me out!
Ive got an iTunes account with over 1300 app store apps, most of which are paid, my kids have just got an iPhone4 and an iPod Touch4 for xmas presents and Im currently setting them up for them to use straight away on xmas day.
The issue is;
For them to be able to use all my apps on their devices Ive had to use my account, this causes issues with things like GameCentre and FaceTime, because we are all on the same e-mail address and account!!!
Is there any way for me to set up there own accounts in such a way as they can still have access to my apps?????
Please help if you can, it would be greatly appreciated,
Thanks, James

How do I authorise them all to use the same apps etc?
that's basically very easy. all you have to do is +log out+ of one account (click on the account name in the Store window and select +sign out+ from the pop-up dialog) and into the other, and then they will both be authorized.

Can two computers use the same backup??

I restored a seperate Macbook pro from the Time machine backup of MY Macbook. So I have two computers operating from the same backup. Is that recommended??

Yes, it should do. Once you change the name of the computer make sure you reset TM
See A4 here. http://pondini.org/TM/Troubleshooting.html
When you start the backup it will create a new sparsebundle.. (like a virtual disk that holds the backup on network drives) and you will be able to check that it is correct because it should be a new full backup.
Then you can do a full backup of one of the machines.. the other machine can continue to use the original backup.

Can two frames use the same SessionInfo object?

Hi,
I have some questions on using InfoBus Frame.
Do parent frame and child frame HAVE TO make use the same
SessionInfo object?
I tried to show Master table and Detailed table in seperate
frame without login twice. I am lucky it works since I happened
to make two frames have the same SessionInfo object which is
sessionInfo1 and conmment out sessionInfo1.publishSession()in
Detailed frame.
But when I tried to pass Master frame SessionInfo object to
Detailed frame there is nothing showing up in the detailed frame
it is just blank frame.
So two frames have to use the same SessionInfo object . Dose it
make sense?
I would really appreciate anyone who can enlighten me on this
subject.
Thanks you so much for the attention.

1.Use wizard and test the frame
2.pass the sessioninfo object in parent to child(put method in
child, call from parent e.g ..getsessionInfo(SessionInfo ss)
3.pass the sessioninfo object to rowsetinfo in child
4.add Database authentication (username/password is sufficient)
methods right before publish method
*publish activates RowSetInfo and connects to db
5.add methods in parent to call child
That should work though depending on how you have set up your
wizard generated java form, might tweak

Can two people use the same computer with two different ipods?

I was just wondering if me and my mother can use the same computer with our ipods?

Glad you asked. Before you get rid of the old one move its iTunes Library to the new one:
iTunes: How to move your music to a new computer
http://support.apple.com/kb/HT4527
"Deauthorize" the old computer too. Go to the iTunes Store menu and select "Deauthorize This Computer..."
I hope you get a Mac this time

Views using the same offscreen buffer, interfering with each other

Hi all,
I am creating an application where I display simulations. In order to keep the view of the simulation ticking along nicely, I paint the view to an offscreen buffer, and then paint the offscreen buffer to the screen.
This has worked fine for me, so long as I was only viewing one single simulation on the screen at a time. I have now started displaying multiple simulations, and the views have started to interact with eachother -- one will paint over the other, particularly when I click or drag the simulation.
I'm not using any static variables, so my guess is that the fault is the offscreen buffer that I'm using. I think my various views are using the same buffer. Is it possible that this is the problem?
Here's how I paint my view:
private BufferedImage offImg;
private Graphics2D offG;
public Graphics2D createGraphics2D(){
          if (offImg != null) {
               offImg.flush();
               offImg = null;
          RepaintManager repaintManager = RepaintManager.currentManager(this);
          try {
          offImg = (BufferedImage) repaintManager.getOffscreenBuffer(
                    this, this.getWidth(), this.getHeight());
          } catch (java.lang.NullPointerException e){
               return null;
          offG = offImg.createGraphics();
          // .. clear canvas ..
          offG.clearRect(0, 0, getSize().width, getSize().height);
          return offG;
private void draw() {
      if (offG == null)
               createGraphics2D();
     offG.drawImage(...) //etc
public void paintComponent(Graphics g){
           g.drawImage(offImg, 0, 0, this);
      }My first thought was to create a list of all the offImg's created and compare them. The different views are indeed getting the same image from repaintManager.getOffscreenBuffer, even though the component passed in as 'this' is different. The offG's created by each view are different, but since they belong to the same image, I assume it's the image that's important.
Is this likely to be the source of my woes, and, assuming that I want to keep using the offscreen buffer (I do) is there a way around this problem?
Thanks so much for any advice.

Hello,
I am creating an application where I display simulations. In order to keep the view of the simulation ticking along nicely, I paint the view to an offscreen buffer, and then paint the offscreen buffer to the screen.You may know that Swing uses double-buffering by default. So you usually don't really need to tweak Swing's own offscreen buffers.
Painting conservatively on an applicative offscreen buffer is sounds (if painting is slow), but then your application has to create a dedicated offscreen buffer, not use Swing's ones.
This has worked fine for me, so long as I was only viewing one single simulation on the screen at a time. I have now started displaying multiple simulations, and the views have started to interact with eachother -- one will paint over the other, particularly when I click or drag the simulation.
I'm not using any static variables, so my guess is that the fault is the offscreen buffer that I'm using. I think my various views are using the same buffer. Is it possible that this is the problem?I can't tell for sure, but I'm not surprised if that's the case: all Swing ("lightweight") widgets within a same JFrame (or any other "heavyweight" top-level container) share the same native graphical resources, so presumably share the same offscreen buffer. It is Swing's machinery that arranges so that each widget paints onto a part of this buffer that corresponds to the widget's bounds.
          offImg = (BufferedImage) repaintManager.getOffscreenBuffer(
                    this, this.getWidth(), this.getHeight());You don't have to, and probably should not, ask Swing's RepaintManager for a buffer. You vould create a BufferedImage yourself, then draw onto it.
offImg = new BufferedImage(...);Then your paintComponent method itself is fine:
public void paintComponent(Graphics g){
           g.drawImage(offImg, 0, 0, this);
Is this likely to be the source of my woes, and, assuming that I want to keep using the offscreen buffer (I do) is there a way around this problem?See above. And look for "offscreen graphics" on this forums, you'll probably find a lot of examples that do this way (and give example code, my sample above is sketchy and untested).
Regards,
J.

Read this article if you need to kick the best out of your fast painting code (in particular, it mentions more informed ways than mine to create Image instances suitable for offscreen drawing):

I made a new apple id because I couldnt access my other one. How do I use the same game center without knowing the old password?

My old apple id basically kicked me off of it (Password became incorrect and I couldnt change it back) so I made a new one. I had apps on the old one that used the gamecenter. This hasnt been a problem, but now it wants me to put in the password for my old account to use the apps. I do not want to lose all of my progress, so is there any way for me to bypass this, or just connect it to my new account? (Specifically, I am playing Clash of Clans. I open the app, then after a few moments the gamecenter pops up and asks for my old password to continue. I tried just connecting my device to my phone, but it also needed the password for that too)

ALL purchases are permanently associated with whatever Apple ID was used to originally obtain them. Apps can not be updated without knowledge of that ID and, more importantly, its password. Apple IDs can not be merged and purchases can not be transferred from one ID to another.

Home sharing suddenly stopped working. All devices have home sharing enabled, all devices are using the same network but cant see each other

I've gone through all the Googling and support forums I can handle.. They all tell me to the same things. I have done everything required and quite honestly Home Sharing was working for quite some time. So I don't think I changed anything.
The only culprit I can think of is the wireless network. We had to call Comcast and reset our service, and they gave us a new modem. Our router is also new.
Is there a setting in a router that lets multiple devices connect but blocks each of them to each other? That seems to be what's happening.
Apple TV2 can see our connection no problem and can download trailers (downloading movies never works though!!!), we have two Macs and two iPhones and all are on our wireless and none can connect to one another using Home Sharing.
Please help!! This is an odd one!!

I believe this is true. Alas, I wrote this a while ago and the link is dead. I can't totally remember what the issue was.
But, looking through the PDF for the Linksys e2000, searching for 'filter multicast' I see this:
Filter Multicast The multicasting feature allows for multiple transmissions to specific recipients at the same time . If multicasting is permitted, then the Router will allow IP multicast packets to be forwarded to the appropriate computers . Select this option to enable the filter . This option is disabled by default.
And in my settings it's been enabled. So maybe try that.
Filter multicast is under Securtiy>Firewall after you log in as admin.
Why it's disabled by default I do not know.
Good luck! Hope this is the solution!! Apple should warn people of this feature conflict to Apple TV buyers.

Can two people use the same Nike plus and Nano?

Or will we each need our own. My husband purchased one and I would also like to use it. We work out at different times and it would be nice not to have to purchase different units, but will it upload both or our workout information or does anyone know if we can pick which workouts to upload. Thanks!!
rachel

All the workout data would get uploaded to the Nike+ website into a single-user's data.
However, if you really don't want to buy two units, the Nike+ website does offer you the ability to "name" your workouts. So, each time you work out, the two of you could give your workouts a name that would allow to differentiate whose is whose. For instance, "His Workout #1" and "Her Workout #1," etc. The combined totals would represent both "His" and "Her" workout totals, but you could at least tell the difference between individual workouts.
Hope this helps!

Can two users use the same ipad for their personal email?

I have one email account assigned to my ipad and I would like to have my girl friend use it while we are traveling. How can she set up her account?

Depends on how much you trust your girlfriend. iOS does not support multiple user accouts at this time. You are not limited to just a single email account. Your girlfriend can add her account to the mix but you must realize she can also get and read email from YOUR account too because she is using your iPad. You cannot set up a different iPad user account that only she can see. Everything is open and available for her to use.

HT201209 Can two iphones use the same itune gift card?

My husband and I are new to iphones, and would like to purchase one itunes gift card and both use it on our iphones. I have an apple id set up, he does not yet have one. Can we share an itunes account if we have different apple id's?

Related question... I have read mixed reviews on whether or not families with multiple apple products should have a single or many apple ids. This site is interesting... http://gigaom.com/apple/how-many-apple-ids-should-your-family-have/comment-page- 2/
Is there a general consensus on this issue? Since my husband has not yet set up an apple id, this is the time we need to decide.
Thanks so much!

I have two iphones using the same computer and I can only find a backup for my iphone and not my girlfriends. She uses itunes a lot more often then I do but cant find it

I have two iphones using the same computer and I can only find a backup for my iphone and not my girlfriends. She uses itunes a lot more often then I do but cant find it. Really need some help. Shouldnt her apps and details be saved online in the itunes store? Even her apps wont appear

If you create an Apple ID for your daughter, signing out of the existing Apple ID with the iTunes & App Store on her iPhone will not change anything on your iPhone.
All apps include DRM protection which is tied to the Apple ID that was used to download the apps.
If she starts using her Apple ID to download apps, when there is an app update for an app on her iPhone that was downloaded with the current shared Apple ID, she will need to use that Apple ID and password to download the app updates.

Can two users on the same Mac sync contacts by using the same Apple ID in the iCloud settings?

Can two users on the same Mac sync contacts by using the same Apple ID in the iCloud settings?

Hi Barney,
That's exactly what I want. I have a personal user and a business user on my MacBook Pro. I want both users to have the same contacts so if I add a contact while I'm logged into my personal user, it will show up when I'm logged into my business user. I want both contacts books to be exactly the same; like you said. So, I used my business user AppleID when I enabled iCloud for my personal user and I enabled iCloud for my business user with that Apple ID as well. For my personal user, I selected Contacts and Calendars to sync with iCloud. For my business user, I selected everything to sync with iCloud. The problem is... it didn't change anything. I restarted my computer to see if that would do anything but nothing happened. I'm not super savvy with Apple products, so maybe I'm completely confused.
Hi Xeni,
Thank you for your response, as well.
