  • Is there a way to find out if an iPhone / iPad app is installed already?

    - by eerok512
    I'm writing a freeware version of an app and would like to check if a user already has the unfree version installed, and print a message whose contents are conditional on the results of the installation check... anybody know if this is possible? the closest I've come to a solution is to make use of the CFPreferencesSetValue API with a kCFPreferencesAnyUser / kCFPreferencesCurrentHost pairing... I haven't tried it, but based on the documentation it sounds possible. however in my current specific situation this API will not be able to solve my problem, because I want to check for the presence of an app I wrote 4 months ago that didn't write any data to the CFPrefs registry... because back then I didn't know of it nor did I foresee this situation arising... the only way CFPrefs can assist me is in future apps now that I know it exists :) so I'm wondering if there are other ways to do it? any help will be appreciated :)

    - by Atulkumar V. Jain
    Hi Everybody, I am trying to upload a image which i am clicking with the help of the camera. I am trying the following code to upload the image to the remote server. -(void)searchAction:(UIImage*)theImage { UIDevice *dev = [UIDevice currentDevice]; NSString *uniqueId = dev.uniqueIdentifier; NSData * imageData = UIImagePNGRepresentation(theImage); NSString *postLength = [NSString stringWithFormat:@"%d",[imageData length]]; NSString *urlString = [@"http://www.amolconsultants.com/im.jsp?" stringByAppendingString:@"imagedata=iPhoneV0&mcid="]; urlString = [urlString stringByAppendingString:uniqueId]; urlString = [urlString stringByAppendingString:@"&lang=en_US.UTF-8"]; NSLog(@"The URL of the image is :- %@", urlString); NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:urlString]]; [request setHTTPMethod:@"POST"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setHTTPBody:imageData]; NSURLConnection *conn=[[NSURLConnection alloc] initWithRequest:request delegate:self]; if (conn == nil) { NSLog(@"Failed to create the connection"); } } But nothing is getting posted. Nothing comes in the console window also. I am calling this method in the action sheet. When the user clicks on the 1st button of the action sheet this method is called to post the image. Can anyone help me with this... Any code will be very helpful... Thanx in advance...

  • Newbie question: Creating a custom control

    - by Wild Thing
    Hi, I have an ASP.Net site, in which I am using a ListView with a Datapager. Apparently there is a bug with the Datapager, where it crashes if there is an empty ampersand (&) in the querystring. This is a known issue: https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=357344&wa=wsignin1.0#tabs I see that there is a workaround given, but did not understand how to implement it. Can somebody point me in the right direction? Also, I see that this issue is marked as resolved. Any idea where I can find the updated version of this control? Wild Thing

  • IPhone sdk stop the accelerometer from working when something happens.

    - by Harry
    Hi, I am using the accelerometer to move a few UIImageViews around the screen, at the moment the accelerometer only works when a NSTimer is at 0, this is fine. I would also like to make the accelerometer stop again when a different function happens. here is my code at the moment: -(BOOL) accelerometerWorks { return time == 0; } -(void) accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration{ if(![self accelerometerWorks]) return; valueX = acceleration.x*25.5; int newX = (int)(ball.center.x +valueX); if (newX 320-BALL_RADIUS) newX = 320-BALL_RADIUS; if (newX < 0+BALL_RADIUS) newX = 0+BALL_RADIUS; int XA = (int)(balloonbit1.center.x +valueX); if (XA 320-BALL_RADIUS) XA = 320-BALL_RADIUS; if (XA < 0+BALL_RADIUS) XA = 0+BALL_RADIUS; int XB = (int)(balloonbit2.center.x +valueX); if (XB 320-BALL_RADIUS) XB = 320-BALL_RADIUS; if (XB < 0+BALL_RADIUS) XB = 0+BALL_RADIUS; int XI = (int)(balloonbit3.center.x +valueX); if (XI 320-BALL_RADIUS) XI = 320-BALL_RADIUS; if (XI < 0+BALL_RADIUS) XI = 0+BALL_RADIUS; int XJ = (int)(balloonbit4.center.x +valueX); if (XJ 320-BALL_RADIUS) XJ = 320-BALL_RADIUS; if (XJ < 0+BALL_RADIUS) XJ = 0+BALL_RADIUS; int XE = (int)(balloonbit5.center.x +valueX); if (XE 320-BALL_RADIUS) XE = 320-BALL_RADIUS; if (XE < 0+BALL_RADIUS) XE = 0+BALL_RADIUS; int XF = (int)(balloonbit6.center.x +valueX); if (XF 320-BALL_RADIUS) XF = 320-BALL_RADIUS; if (XF < 0+BALL_RADIUS) XF = 0+BALL_RADIUS; int XH = (int)(balloonbit8.center.x +valueX); if (XH 320-BALL_RADIUS) XH = 320-BALL_RADIUS; if (XH < 0+BALL_RADIUS) XH = 0+BALL_RADIUS; ball.center = CGPointMake (newX, 429); balloonbit1.center = CGPointMake (XA, 429); balloonbit2.center = CGPointMake (XB, 426); balloonbit3.center = CGPointMake (XI, 410); balloonbit4.center = CGPointMake (XJ, 415); balloonbit5.center = CGPointMake (XE, 409); balloonbit6.center = CGPointMake (XF, 427); balloonbit8.center = CGPointMake (XH, 417); } This all works fine, i would now like to stop the accelerometer from working, using the same accelerometerWorks method or a new method, accelerometerWontWork. This is the code that when it is called i would like the accelerometer to stop. (it is very long so i wont put all of it there, but its all the same throughout): -(void) checkCollision{ if (CGRectIntersectsRect(pinend.frame, balloonbit1.frame)){ if (balloonbit1.frame.origin.y pinend.frame.origin.y){ [maintimer invalidate]; levelfailed.center = CGPointMake (160, 235); } } if (CGRectIntersectsRect(pinend.frame, balloonbit2.frame)){ if (balloonbit2.frame.origin.y pinend.frame.origin.y){ [maintimer invalidate]; levelfailed.center = CGPointMake (160, 235); } } if (CGRectIntersectsRect(pinend.frame, balloonbit3.frame)){ if (balloonbit3.frame.origin.y pinend.frame.origin.y){ [maintimer invalidate]; levelfailed.center = CGPointMake (160, 235); } } } I understand that i may have to turn this into a BOOL. Thats fine. If i haven't explained it well please say and i will re write it. Thanks! Harry.

  • How do I control the background color during the iPhone flip view animation transition?

    - by Rob S.
    I have some pretty standing flipping action going on: [UIView beginAnimations:@"swapScreens" context:nil]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES]; [UIView setAnimationDuration:1.0]; [self.view exchangeSubviewAtIndex:0 withSubviewAtIndex:1]; [UIView commitAnimations]; To Apple's credit, this style of animation is amazingly easy to work with. Very cool, and I've been able to animate transitions, flips, fades etc. throughout the app very easily. Question: During the flip transition, the background visible 'behind' the two views during the flip is white and I'd like it to be black. I've: Set the background of the containing view (self.view above) - no dice. I really thought that would work. Set the background of each view to black - no dice. I didn't think this would work although you give different things a shot to understand better :) Google'd like crazy; keep landing on Safari-related listings. Thanks in advance!

  • Newbie question: When to use extern "C" { //code } ?

    - by Russel
    Hello, Maybe I'm not understanding the differences between C and C++, but when and why do we need to use: extern "C" { ? Apparently its a "linkage convention"? I read about it briefly and noticed that all the .h header files included with MSVS surround their code with it. What type of code exactly is "C code" and NOT "C++ code"? I thought C++ included all C code? I'm guessing that this is not the case and that C++ is different and that standard features/functions exist in one or the other but not both (ie: printf is C and cout is C++), but that C++ is backwards compatible though the extern "C" declaration. Is this correct? My next question depends on the answer to the first, but I'll ask it here anyway: Since MSVS header files that are written in C are surrounded by extern "C" { ... }, when would you ever need to use this yourself in your own code? If your code is C code and you are trying to compile it in a C++ compiler, shouldn't it work without problem because all the standard h files you include will already have the extern "C" thing in them with the C++ compiler? Do you have to use this when compiling in C++ but linking to alteady built C libraries or something? Please help clarify this for me... Thanks! --Keith

  • How do you get the viewport scale after pinch/zoom on an iPhone web app?

    - by Loktar
    Does anyone know how to get the size in pixels or scale value of the viewport after a user has pinched or double tapped to zoom in/out on a page in JavaScript? I've tried using window.innerWidth but I've had mixed results. Sometimes it seems to accurately give the number of pixels the viewport is showing, however, if I zoom way in on a page and then do a large pinch to zoom back out, window.innerWidth will be around 600-700 even though it is only showing ~200px of the page. The page is only 400px wide and it didn't show the checkered "you've gone too far" background you see when you zoom out beyond the page size. If I do small pinches to zoom in and out, window.innerWidth appears to work just fine. Unfortunately I can't rely on a user only making small pinch gestures :) I've also tried to use the scale property on the gesture event object, but I've found that unreliable because you don't always know the initial scale when you reload the page or use back/forward buttons to navigate to it even when using the meta tag to specify it. Ultimately, I'm trying to make an app that is aware of when a user is trying to zoom out beyond the maximum zoom level so if there is another way to do this I'm interested in hearing about it :) Here's the code I'm using to get the innerWidth: document.body.addEventListener('gestureend', function (evt) { console.log(window.innerWidth); // inaccurate when doing large pinch gestures }, false); Thanks!

  • (Newbie) Amazon Web Services Apache Server

    - by Samnsparky
    Hello! I am trying to get a feel for the costs imposed by running apache on AWS continually. Assuming that the service is scarcely used, does anyone know how many cpu hours that would eat up in a month just by sitting there and running? I understand that this is slightly impractical but I am trying to figure out what the cost of entry is to deploy an application on this platform (as compared to GAE). I suspect it to be small but I would like to know. Thank you for your help, Sam

  • Converting "fr_FR" into "French (France)" in both directions. (Objective-C iPhone)

    - by Janice
    I can easily change a short region-code (en_US) into a longer string... but it there an easy way to also move in the other direction? [displayInEnglish displayNameForKey:NSLocaleIdentifier value:regionCountryCode]; "en_US" becomes "English (United States)". "English (United States)" becomes "en_US". I currently store the short region-code in a database.... but when I show some aggregate results... I need to display the longer strings to the user. Or should I just store the longer strings right in the database... and not even worry about "converting" them later? I'm trying to show a "dollars total" for each country. If you were a user... which would you more likely wish to see (for a currency-total list)? A "French" total A "France" total A "French (France)" total A "fr_Fr" total?

  • Is there an easy way to stream a m3u in iPhone?

    - by marty
    I can have a UIWebView with the .m3u file opened, which will go to the webview with a play button displayed, and that automatically goes to the quicktime player and starts playing the stream. But when I press the done button, it goes back to the UIWebView with a little play button in the middle, and from there you can go back to the previous screen (it was selected from a tableview). So I just want it to automatically load the quicktime player in the view. How can I do that?

  • RewriteCond and RewriteRule newbie

    - by mybrokengnome
    I'm taking over a website for a client that is running on a custom built CMS (that I didn't write). I don't mess with .htaccess files usually because a lot of the hosting I do is on IIS, or I used WordPress as a CMS and don't have to worry about messing with the .htaccess file. Here's the contents of the file: RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ framework.php?%{QUERY_STRING}&resource=$1& [L] I get what it's doing (sending all requests through the framework.php file). The client wants a WordPress blog added to their site. I'm placing it in a /blog/ folder. The problem is that because of the rewrite rules and conditions in the .htaccess file whenever I try to go /blog/ the other CMS freaks out because it doesn't like me trying to go there. My question is how do I write a rule/cond that tells apache to send all requests made to the /blog/ folder to the /blog/ folder, but keep all other requests piped through the framework.php file like it is now? Any help is appreciated, thanks!

  • What's a better way to display a handle for resizing a view on iPhone / iPad?

    - by Christian
    I want to display a handle at the corners of a UIView that can be used to resize the view. How can I display the handles floating on the top of everything else and still have a connection to and be in sync with a view? The solution I implemented before looks like this: I put the view into another view that shows the handles on top of the corners. The problem with this approach is that the handles add extra space to the original view's size. Since Apple recommends at least 40 x 40 px for the size of a button, it is not very little space and also goes beyond the visible bounds of the original view. Another problem is that the original view has to be encapsulated in this 'helper view' object and thus becomes a part of something although it really is the main component.

  • Scala newbie vproducer/consumer attempt running out of memory

    - by Nick
    I am trying to create a producer/consumer type Scala app. The LoopControl just sends a message to the MessageReceiver continually. The MessageReceiver then delegates work to the MessageCreatorActor (whose work is to check a map for an object, and if not found create one and start it up). Each MessageActor created by this MessageCreatorActor is associated with an Id. Eventually this is where I want to do business logic. But I run out of memory after 15 minutes. Its finding the cached actors,but quickly runs out of memory. Any help is appreciated. Or any one has any good code on producers consumers doing real stuff (not just adding numbers), please post. import scala.actors.Actor import java.util.HashMap import scala.actors.Actor._ case object LoopControl case object MessageReceiver case object MessageActor case object MessageActorCreator class MessageReceiver(msg: String) extends Actor { var messageActorMap = new HashMap[String, MessageActor] val messageCreatorActor = new MessageActorCreator(null, null) def act() { messageCreatorActor.start loop { react { case MessageActor(messageId) => if (msg.length() > 0) { var messageActor = messageActorMap.get(messageId); if(messageActor == null) { messageCreatorActor ! MessageActorCreator(messageId, messageActorMap) }else { messageActor ! MessageActor } } } } } } case class MessageActorCreator(msg:String, messageActorMap: HashMap[String, MessageActor]) extends Actor { def act() { loop { react { case MessageActorCreator(messageId, messageActorMap) => if(messageId != null ) { var messageActor = new MessageActor(messageId); messageActorMap.put(messageId, messageActor) println(messageActorMap) messageActor.start messageActor ! MessageActor } } } } } class LoopControl(messageReceiver:MessageReceiver) extends Actor { var count : Int = 0; def act() { while (true) { messageReceiver ! MessageActor ("00-122-0X95-FEC0" + count) //Thread.sleep(100) count = count +1; if(count > 5) { count = 0; } } } } case class MessageActor(msg: String) extends Actor { def act() { loop { react { case MessageActor => println() println("MessageActor: Got something-> " + msg) } } } } object messages extends Application { val messageReceiver = new MessageReceiver("bootstrap") val loopControl = new LoopControl(messageReceiver) messageReceiver.start loopControl.start }
