  • Android continue à progresser face à l'iPhone, malgré un Android Market qui enchaîne les bourdes

    Mise à jour du 15/06/10 Android continue à progresser face à l'iPhone Malgré un Android Market qui enchaîne les dysfonctionnements Les chiffres sont bons pour Android. D'après la société de mesure d'audience quantcast, l'OS mobile de Google continue de gagner des parts de marché (PDM) aux Etats-Unis, notamment aux dépends de l'iPhone (et du nouvellement nommé iOS).

  • Reassessment: What's a good analytics package to use for tracking user behavior in a native iOS app?

    - by BeachRunnerJoe
    Hello. I've been poking around google and SO for answers on this, but it doesn't seem to be very well discussed, so I thought I revisit the question. Is anyone using any analytics packages (like Google Analytics or Mixpanel) to track user behavior in their native iOS apps? The three I've come across are Flurry, Mixpanel, and Google Analytics. It sounds like Apple is still peeved at Flurry, so I don't want to mess with that. Mixpanel looks simple and easy to use, but I'd first like to hear from someone who has used it. Same goes with Google Analytics for the iPhone. I've just finished building an iPhone game and I'd like to begin tweaking it based on how the users are playing it. Does anyone have any recommendations or experience with any of these analytics packages? Thanks so much!

  • How do these hotshot developers keep changing their technology base ?

    - by pankajdoharey
    Yesterday I was watching a lynda.com iphone development video and this developer started telling about how he has worked on 17 different languages from the days of mainframes in assembly/Cobol to now on iPhone Objective-C. My question is how do these developers keep shifting to new technology, without fearing the loss of experience they already have about a particular technology. I am trying to shift to Java from PHP and market considers this as non-relevant experience. How do these guys do it without losing the pay and not being considered a fresher in a particular technology.

  • Google gagne plus d'argent avec l'iPhone qu'avec Android d'après The Guardian, quatre fois plus

    Google gagne plus d'argent avec l'iPhone qu'avec Android D'après The Guardian, quatre fois plus même Le monde des mobiles est décidément étonnant. Après Microsoft - qui gagne de l'argent grâce à Android, ses brevets et des royalties versées par plusieurs constructeurs (lire ici et là) - on apprend aujourd'hui que c'est Google qui engrange des revenus grâce à un concurrent. Et pas n'importe lequel puisqu'il s'agit du leader du marché lui-même : l'iPhone. Ces revenus seraient même tellement importants que, toujours d'après The Guardian, Google gagnerai...

  • Are Large iPhone Ping Times Indicative of Application Latency?

    - by yar
    I am contemplating creating a realtime app where an iPod Touch/iPhone/iPad talks to a server-side component (which produces MIDI, and sends it onward within the host). When I ping my iPod Touch on Wifi I get huge latency (and a enormous variance, too): 64 bytes from 192.168.1.3: icmp_seq=9 ttl=64 time=38.616 ms 64 bytes from 192.168.1.3: icmp_seq=10 ttl=64 time=61.795 ms 64 bytes from 192.168.1.3: icmp_seq=11 ttl=64 time=85.162 ms 64 bytes from 192.168.1.3: icmp_seq=12 ttl=64 time=109.956 ms 64 bytes from 192.168.1.3: icmp_seq=13 ttl=64 time=31.452 ms 64 bytes from 192.168.1.3: icmp_seq=14 ttl=64 time=55.187 ms 64 bytes from 192.168.1.3: icmp_seq=15 ttl=64 time=78.531 ms 64 bytes from 192.168.1.3: icmp_seq=16 ttl=64 time=102.342 ms 64 bytes from 192.168.1.3: icmp_seq=17 ttl=64 time=25.249 ms Even if this is double what the iPhone-Host or Host-iPhone time would be, 15ms+ is too long for the app I'm considering. Is there any faster way around this (e.g., USB cable)? If not, would building the app on Android offer any other options? Traceroute reports more workable times: traceroute to 192.168.1.3 (192.168.1.3), 64 hops max, 52 byte packets 1 192.168.1.3 (192.168.1.3) 4.662 ms 3.182 ms 3.034 ms can anyone decipher this difference between ping and traceroute for me, and what they might mean for an application that needs to talk to (and from) a host?

  • Why is a CoreData forceFetch required after a delete on the iPad but not the iPhone?

    - by alyoshak
    When the following code is run on the iPhone the count of fetched objects after the delete is one less than before the delete. But on the iPad the count remains the same. This inconsistency was causing a crash on the iPad because elsewhere in the code, soon after the delete, fetchedObjects is called and the calling code, trusting the count, attempts access to the just-deleted object's properties, resulting in a NSObjectInaccessibleException error (see below). A fix has been to use that commented-out call to performFetch, which when executed makes the second call to fetchObjects yield the same result as on the iPhone without it. My question is: Why is the iPad producing different results than the iPhone? This is the second of these differences that I've discovered and posted recently. -(NSError*)deleteObject:(NSManagedObject*)mo; { NSLog(@"\n\nNum objects in store before delete: %i\n\n", [[self.fetchedResultsController fetchedObjects] count]); [self.managedObjectContext deleteObject:mo]; // Save the context. NSError *error = nil; if (![self.managedObjectContext save:&error]) { } // [self.fetchedResultsController performFetch:&error]; // force a fetch NSLog(@"\n\nNum objects in store after delete (and save): %i\n\n", [[self.fetchedResultsController fetchedObjects] count]); return error; } (The full NSObjectInaccessibleException is: "Terminating app due to uncaught exception 'NSObjectInaccessibleException', reason: 'CoreData could not fulfill a fault for '0x1dcf90 <x-coredata://DC02B10D-555A-4AB8-8BC4-F419C4982794/Blueprint/p"

  • iPhone table header lables not showing up in Release build but show up OK in Debug build

    - by Robert
    My table header shows up ok with Release build or Debug build for the iPhone simulator, but the header labels only show up with debug build on the iPhone. No header labels show up on the iPhone for release build. Any ideas? Thanks, Robert My code for the header is below - (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)sectionNum { @try { // create the parent view that will hold header Label UIView* customView = [[[UIView alloc] initWithFrame:CGRectMake(HEADER_RELX_OFFSET, HEADER_RELY_OFFSET, HEADER_ROW_WIDTH, HEADER_HEIGHT)] autorelease]; UILabel* headerLabel = [[UILabel alloc] initWithFrame:CGRectZero]; headerLabel.backgroundColor = [UIColor clearColor]; headerLabel.opaque = NO; headerLabel.numberOfLines = 0; headerLabel.textColor = [UIColor blackColor]; headerLabel.highlightedTextColor = [UIColor whiteColor]; headerLabel.font = [UIFont boldSystemFontOfSize:HEADER_FONT_SIZE]; headerLabel.textAlignment = UITextAlignmentCenter; headerLabel.lineBreakMode = UILineBreakModeWordWrap; headerLabel.frame = CGRectMake(HEADER_RELX_OFFSET, HEADER_RELY_OFFSET, HEADER_ROW_WIDTH, HEADER_HEIGHT); if(sectionNum == 0) headerLabel.text = @"My Label"; else headerLabel.text = @""; [customView addSubview:headerLabel]; return customView; @catch (NSException* exception) { NSLog(@"viewForHeaderInSection: %@: %@",[exception name],[exception reason]); } }

  • How do I secure a .NET Web Service for use by an iPhone application?

    - by David A Gibson
    Hello, The title says it all, I have a Web Service written in .NET that provides data for an iPhone application. It will also allow the application make a "reservation." Currently it's all internal to the corporate network but obviously when the iPhone application is published I will need ensure the Web Service is available externally. How would I go about securing the Web Service? There are two aspects I'm looking into: Authentication for accessing the web service Protection for the data being transferred I'm no so bothered about the data being passed back and forth as it will be viewable in the application anyway (which will be free). The key issue for me is preventing users from accessing the Web Service and making reservations themselves. At the moment I am considering encrypting any strings in the XML data passed back and forth so only the client can effectively use the web service sidestepping the need for authentication and providing protection for the data. This is the only model I have seen but I think the overheads on the iPhone and even for the web service make for a poor user experience. Any solutions at all would be most welcome? Thanks

  • What are possible/good ways to prototype iPhone applications?

    - by Ted Johnson
    This is intentionally left broad. If you wanted to show users what iPhone/mobile applications could to for them. The more interactive the better, but it must be quick to build as you can't code up every idea. Let us assume real-time games are out of scope. Throw out ideas or state which approach would be best. Here are some of my ideas, what are yours? Hack a app that loads mostly web or image content, but has hyperlinks to get around in. This would mean static data. Build screens which look great but can only be navigated in a story board type fashion. Load the web version or equivalent on the iPhone and say: now image the buttons and navigation is better. A paper based prototype. Flash or video walk through running on the phone. String existing iPhone apps and web pages together with minimal glue just to convey the idea. Can anyone share prototyping methods for other mobile devices? Ex: The palm prototype was just a block of wood and note pad that was carried around.

  • MPMoviePlayerController seems to make 2 calls for each movie

    - by user76328
    I seem to have an issue where an iphone app using the MPMoviePlayerController seems to make 2 calls to the server for each video it wants to play back. This occurs with iphone 3.x OS and libraries but not with iphone 2.x. I know that iphone does progressive download and will make multiple 206 requests, etc. but as far as our back end is concerned the player appears to make 2 separate sessions. This only appears to be an issue with iPhone native apps and not iphone videos played through safari. Additional info from apple: iPhone OS 3.0 added support for streaming audio and video over HTTP, and MPMoviePlayerController must validate the media before playback to determine if it is streaming content or progressively downloaded content. This is the delay you are experiencing. On a fast network, the delay should be minimized. Is this double check causing 2 sessions be created for each video request? Any one else seeing same issue? Is there a remedy?

  • Which is the best way to sync and share contacts and calender between Thunderbird, iPhone and Android?

    - by bensch
    I would like to keep my contacts and a calendar synchronized between several desktops and cellphones. Is there a way to achieve this without using Google or similar organisations? I want to keep my data protected and safe, so an encrypted transfer would be useful. Do i need to install a service on my own rootserver? or are there any services available, that are safe? I read this post, but there is not mentioned not to use Google: Thunderbird contacts sync so no solutions with SoGo or LDAP. maybe Zimbra is a solution? or Funambol? I tried kolab, but had some unsolveable problems.
