    - by iPhone Fun
    hi friends, I want to change the sprite image while my application is running. I've taken 5 different sprite objects with different images. but when I use [self removeChild:Name of sprite cleanup:YES]; It is not removing the sprite. So is there any other way to perform such task?? Any help?? Thanks in advance.

  • Cocos2d on iPhone: Using Sprites Defined in Separate Class Files.

    - by srikanth rongali
    I'm trying to draw two sprites on the same screen. I have defined the two sprite objects in two separate class files. If I comment out two lines (see "item 1" comment below) then I get a display as [a backgroundimage[background2.jpg] with a sprite[grossini.png] on the left side. If I uncomment the two lines I do not get the background image and sprite of (gameScreen.m). I get only the sprite [grossinis_sister1.png] defined in (enemy.m). But what I need is a [backgroundimage[background2.jpg]], sprite[grossini.png] and sprite [grossinis_sister1.png] in one screen. This is implementation file of my first class: #import "gameScreen.h" #import "enemy.h" @implementation gameScreen -(id)init { if((self = [super init])) { CCSprite *backGroundImage = [CCSprite spriteWithFile:@"background2.jpg"]; backGroundImage.anchorPoint = ccp(0,0); CCParallaxNode *voidNode = [CCParallaxNode node]; [voidNode addChild:backGroundImage z:-1 parallaxRatio:ccp(0.0f,0.0f) positionOffset:CGPointZero]; [self addChild:voidNode]; CGSize windowSize = [[CCDirector sharedDirector] winSize]; CCSprite *player = [CCSprite spriteWithFile:@"grossini.png"]; player.position = ccp(player.contentSize.width/2, windowSize.height/2); [self addChild:player z:0]; //eSprite = [[enemy alloc]init]; //<-- see item 1 //[self addChild:eSprite]; } return self; } This is my implementation file of my second class: #import "enemy.h" #import "gameScreen.h" @implementation enemy -(id)init { if ((self = [super init])) { CGSize windowSize = [[CCDirector sharedDirector] winSize]; CCSprite *enemySprite = [CCSprite spriteWithFile:@"grossinis_sister1.png" ]; enemySprite.position = ccp(windowSize.width/2, windowSize.height/2); [self addChild:enemySprite]; } return self; } @end

    - by Paul
    I'd like to be able to determine which store the user connects to from inside my app, so that I can direct them to some appropriate content for their device AND store. Does anyone know how to get this information? Basically, if the user is in the UK, and connects to the UK store, I want my function/method to return GB, if in Korea, I want KR, Australia = AU etc. Any help would be appreciated.

  • Button to add value to array and then compare result with another array on IPhone.

    - by slickplaid
    I have ten buttons that each correspond to a different number. I'm looking to record the order that these buttons are pressed and enter them into an array and then compare it to another array that is static in the app. The check should be done on the Nth button press, where N equals the number of items in the other, static array. How do I A) have a button press add a value to an array B) stop after Nth button press equal to amount of numbers in the array I'm checking against and C) compare this array to the other array?

  • iPhone SDK: How do I programatically change the background image of a UIButton added to a NIB?

    - by user304583
    I've seen several questions/answers related to entirely creating a button in code, but not one which would let me know how to change the button image in code, when I originally added the button to my NIB in Interface Builder. I know how to change the background in Interface Builder.. but I want to change it in code, so I can change it automagically. Any help really appreciated! Perhaps the answer is so obvious nobody needs to ask.. if so please forgive the dweeb that I am and help! :-)

    - by Skie
    I have some HTML loaded in WebView like this: <html><head></head><body>before <myTag>Content</myTag> after</body></html> I want to replace element myTag with custom text so it should look like: <html><head></head><body>before ____MY_CUSTOM_TEXT___ after</body></html> Also I can't change initial HTML.

  • Redrawing content of UIWebView

    - by btate
    I have a bunch of webviews with static html content that I'm putting in a scroll view as pages. That works fine, but having 20 something full screen subviews of the scroll view is causing some lag. I solved that by only placing 5 at a time in there. The current view, and the two next and two previous. The problem now is that any web view that is not a subview of the scroll view is not drawing correctly based on the device orientation. The frame of the webview is printing out correct, but the actual content is drawing in portrait mode. So there is essentially a strip of blank space to the right of the content. How do I go about re rendering the content without reloading the page? Here's the relevant code: - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation) fromInterfaceOrientation{ [self resizeSubViews]; } - (void) setupWebViews{ if(_webViews == nil) _webViews = [[NSMutableArray alloc] init]; // This is where the navigation would come into play as far as loading up available web views [_webViews removeAllObjects]; // for loop here to create web views for (int i = 0; i < 20; i++) { //CDCWebViewController *webView = [[[MyInternalWebView alloc] initWithFrame:_webViewWrapper.frame] retain]; MyInternalWebView *page = [[[MyInternalWebView alloc] init] retain]; [page loadRequest:[NSURLRequest requestWithURL:_url]]; [page setCdcIWVdelegate:self]; [page setTestIndex:i]; [page setPageIndex:i]; [_webViews addObject:page]; [self loadScrollViewWithPage:i]; } [self clearUnusedWebViews:_pageControl.currentPage]; } - (void) setupWebViewWrapper{ // a page is the width of the scroll view _webViewWrapper.pagingEnabled = YES; _pageControl = [[[UIPageControl alloc] init] retain]; _webViewWrapper.showsHorizontalScrollIndicator = NO; _webViewWrapper.showsVerticalScrollIndicator = NO; _webViewWrapper.scrollsToTop = NO; _webViewWrapper.delegate = self; _pageControl.numberOfPages = [_webViews count]; _pageControl.currentPage = 0; } - (void) resizeSubViews{ // The frame is set in IB _webViewWrapper.contentSize = CGSizeMake(_webViewWrapper.frame.size.width * [_webViews count], _webViewWrapper.frame.size.height); // Move the content offset. _webViewWrapper.contentOffset = CGPointMake(_webViewWrapper.frame.size.width * _pageControl.currentPage, _webViewWrapper.contentOffset.y); for (MyInternalWebView *subview in _webViewWrapper.subviews) { // Reset the frame height and width here? CGRect frame = _webViewWrapper.frame; frame.origin.x = frame.size.width * subview.pageIndex; frame.origin.y = 0; [subview setFrame:frame]; } } //***************************************************** //* //* ScrollView Functions //* //***************************************************** - (void)loadScrollViewWithPage:(int)page { // Make sure we're not out of bounds if (page < 0) return; if (page >= [_webViews count]) return; MyInternalWebView *webView = [_webViews objectAtIndex:page]; // Add the preloaded webview to the scrollview if it's not there already if (nil == [webView superview]) { CGRect frame = _webViewWrapper.frame; //NSLog(@"width = %f", frame.size.width); frame.origin.x = frame.size.width * page; frame.origin.y = 0; //NSLog(@"setting frame for page %d %@", page, NSStringFromCGRect(frame)); [webView setFrame:frame]; [_webViewWrapper addSubview:[_webViews objectAtIndex:page]]; // Now that the new one is loaded, clear what doesn't need to be here [self clearUnusedWebViews:page]; } } - (void) clearUnusedWebViews: (NSInteger) page{ for (int i = 0; i < [_webViews count]; i++) { if ((page - i) <= 2 && i - page <= 2) { continue; } [[_webViews objectAtIndex:i] removeFromSuperview]; } } - (void)scrollViewDidScroll:(UIScrollView *)sender { // Switch the indicator when more than 50% of the previous/next page is visible CGFloat pageWidth = _webViewWrapper.frame.size.width; NSInteger page = floor((_webViewWrapper.contentOffset.x - pageWidth / 2) / pageWidth) + 1; _pageControl.currentPage = page; // load the visible page and the page on either side of it (to avoid flashes when the user starts scrolling) [self loadScrollViewWithPage:page - 2]; [self loadScrollViewWithPage:page - 1]; [self loadScrollViewWithPage:page]; [self loadScrollViewWithPage:page + 1]; [self loadScrollViewWithPage:page + 2]; }

  • iPhone app getting XML then refreshing it at intervals...

    - by user157733
    I have an app which gets some data from the web via an XML document. I have this working fine and have followed apples SeismicXML example (uses NSURLRequest etc). I am very new to this so I have to admit that I do not totally understand all the code that gets the XML - but it is working. My problem is that my app may be running for some time so I want to be able to refresh the XML every now and again and check to see if it is different. If it is different I need to update my contents. Basically this means my questions are.... Is there a standard way of doing this? I was thinking of creating a timer to call the function which parses the XML but I can't figure out which function to call. If anyone can give me any pointers or even better examples of this it would be fab. Thanks

  • iPhone: How to run a Beta build, in addition to the App Store build?

    - by rondoagogo
    Hi, All! I have an app on the Store for which we’re readying an update. The other members of our team have the App Store version already loaded up (~purchased) on their respective iPhones -- and those contain User Data which each member needs to be able to keep. In the meantime, we need to test out a Beta version of the next version of the app. Presumably, we’d need to have the two versions (ad hoc, and app store) co-existing on each device, at least until everyone’s signed off on the beta, and it’s uploaded to the store (at which point, they'd delete the beta version). [Once it’s on the Store, of course, they can each update their main (i.e., Release) version of the app via the usual App Store 'update' mechanism -- and then delete the beta version from their devices. In that case, all their user data is still retained intact.] So assuming that’s the proper workflow ... How do I issue a Beta to the team, and have it not replace/overwrite the existing App Store version? I’ve tried customizing parameters in the beta’s “[appname]-Info.plist”, but haven’t found a setting yet that allows the two versions (beta and release) to co-exist on the same device. Any ideas? And is this this is the proper approach to them being able to keep their data? (And last, how might I do it with & without a script? I assume there's just one parameter that'd need to be changed.) I hope this all makes sense -- thank you in advance for your help!

  • iPhone App that only shows a webpage. Allowed in App Store? [closed]

    - by aioobe
    I'm building a mobile web-app. One of the requirements from my client is that the user should be able to install (through App Store) a program that displays the webpage. I'm thinking of either just displaying a UIWebView with the web-page or opening the webpage in the browser. This would be my first experience with App Store, so I'd like to ask: Would I run into any troubles regarding acceptance in App Store for such "just-show-whatever-the-server-gives-me" application?

  • How to make iPhone Cisco VPN client work with ASA with certificate authentication

    - by Ben Jencks
    I have an ASA that's providing IPsec VPN services using certificate authentication (no xauth, just the certs). It works perfectly with the Cisco IPsec VPN Client. Now I'm trying to let iPhones connect. I've installed the CA cert and a client certificate on the iPhone with a profile using iPCU, along with the VPN configuration. Then connecting gives the error "Could not validate the server certificate". Additionally, the ASA logs the error "Received encrypted Oakley Informational packet with invalid payloads". FWIW, I receive the same invalid payload error when trying to use the Snow Leopard IPsec client to connect. Has anyone successfully gotten the iPhone IPsec client to work with certificate auth?
