  • Problems persisting Core Data structures on iPhone/iPad

    - by Rivier
    I have an iPhone/iPad app using Core Data to keep my application data. Sometimes, even though I don't get any error messages, the data is not really saved so when the app starts anew, it's all gone. This problem seems to disappear after physically rebooting the device, but otherwise it's pretty random and hard to track. Has anyone seen a similar issue? Also, it seems to happen more often in the iPhone 1st generation, less so in the 3G/3GS, and seldom in the iPad. Very strange...

  • When are sqlite3 views updated?

    - by John Smith
    I have a database on the iPhone which as a view. When I update the dependent tables the view is not updated. It's only updated when I close and reopen the application. From there onwards things are okay: updates reflect immediately. Is there something I need to do to force update of a VIEW?

  • Rendering splash screen on the iPhone using Open GL ES

    - by Rich
    Hi, I want to render a splash screen on the iPhone whilst using an Open GL view. The iPhone screen as we know is 320x480, which is not a power of 2. Before I enter into the world of chopping the texture up and rendering sub parts, or embedding the screen on another texture page I was wondering if there was another way? Is it possible to overlay another view that I could render to using CoreGraphics functions? Or is it possible to render to a Open GL surface using Core Graphics functions. What would you recommend? Cheers Rich

    Hi, is there any easy way in the iPhone SDK to include search bars like those in the iPod app or in the Contacts app? (They behave and look unlike the usual UISearchBars ...) -- Ry

  • iPhone Scroll images horizontally like in AppStore

    - by schaechtele
    Hi there, I was wondering if it's possible to create a HTML div container with some CSS magic that shows a horizontal scrollbar like the one with the screenshots on the iTunes preview on the web. I want this to work in Safari on the iPhone. e.g. http://itunes.apple.com/app/super-monkey-ball/id281966695?mt=8 I would like to use that to display thumbnails in an UIWebView on iPhone. I experimented with the overflow css property but didn't get it to work. Thanks for your replies.

  • iphone web app: open directions in external maps application

    - by munchybunch
    I've seen the answers for opening the Maps app in a native iPhone app, but is there any way to do this in a web app? I've tried changing window.location to http://maps.google.com/maps?q=cupertino for example, to no avail. I've tried using a simple anchor tag linked to http://maps.google.com/maps?q=cupertino, also to no avail. Has anyone gotten this to work before? I'm working on a map-heavy application, and I'd like to provide users with directions at the end. I figured it would be easiest to simply open it up in the Map application. Note: I'm currently testing with just the simulator, could that lead to problems? My iPhone is down for the count at the moment.

  • chapters in videos for the iPhone

    - by Grégoire Cachet
    Is it possible to use chapters in videos for the iPhone in an application? For example: I have a 3 minutes video to play. I have chapter 1 starting at 0s, chapter 2 at 50s, chapter 3 at 95s. Can I start plating the video at 50s (chapter 2) until the end? Can I make it play just the chapter 2 from 50s to 95s? My question is not about how to add chapters to a video. I want to know if this behaviour is available on the iphone.

  • Maximum executable size on the iPhone?

    - by Sirp
    Is there a maximum size of executables or executables + shared objects on the iPhone? I've been developing an app that has been crashing on startup or early in execution with SIGSYS. Removing code from the program has helped, though structuring data so the code is simply not executed does not. This could be memory corruption, of some kind, however when I compiled with -Os rather than -O2 or -O3 the size of my executable goes down from 5.15MB to 3.60MB and the application runs perfectly. I also have a bunch of libraries I use, of course. I'm wondering, is there a limit on the size of executable code on the iPhone? Or am I just 'getting lucky' and masking memory corruption when I use -Os?

  • Free sounds for iPhone games.

    - by Roger Gilbrat
    I'm looking for a good source for sound effects for my iPhone game. I like SoundSnap, but they charge you for every sound you download, not just the ones you end up using. Sound design in games can be a very iterative process and I don't want to pay for 10 sounds I never use before finding the right one. freesound.org is another really good site, but they are all CC licensed and can't be used in commercial games. It's unclear if a free iPhone App is considered commercial (or if my final game will be free). Googling for this returns a huge number of pay sites with horrible web pages. I don't mind paying for sounds, but I want to pay for what I use. Any good personal recommendations?

  • TabBar in NavigationController Based iphone app

    - by iPhoneDev
    I have a simple navigation based iPhone app, in which user can navigate form one view to another view. There is only one view which have 4 tab. Each tab loads a a seperate nib with a corresponding controller. Each nib contains a tableview with some other controls for searching/filtering etc. Apprt from this I dont need tabBar in any view. So for ex: Login View Welcome View (With TabBar) user select Setting tab and select any setting option Setting Detail view(WITHOUT tabbar) Back WelcomView( With Tab Bar) I am confused how to add a tab bar in navigation based template where only one view is using tabBar all other uses Navigation I hope you understand my problem. I am new to iphone so any example/link will help a lot. Thanks

  • iPhone4: Keep playing songs after song selected from Search iPhone screen ends?

    - by Jeremy
    When I first got my iPhone 4, if I selected a song from the "search iPhone" screen (when you hit home twice), iTunes would start playing a playlist of all my songs, starting with the selected one. I recently updated it to 4.2.1 (I don't remember exactly what I was at before). Now, when I select a song from the "Search iPhone" screen, iTunes starts playing a playlist containing only that song. Is there a way I can get the old behavior back?

  • Detecting extended mousedown event on iPhone

    - by Alan Neal
    I want to detect an extended mousedown. The following code works in Firefox and Safari... var mousedownTimeout; $('#testButton').mousedown(function(){ mousedownTimeout = window.setTimeout(function(){ alert("Hey, let go."); }, 2000); }); $('#testButton').mouseup(function(){ window.clearTimeout(mousedownTimeout); }); ... but not on the iPhone because (quoting quirksmore.org)... The iPhone fires the mousedown, mouseup and click events in the correct order on a click (tap), but it either fires all three or none at all. Is there a way around this?

  • Cloud sync between iPad/iPhone app

    - by Macatomy
    I have a Core Data app that will end up being an iPhone/iPad universal application. I would like to implement cloud syncing so that an iPhone and an iPad both running the app could share data. I'm planning to use the recently released Dropbox API. Does anyone have any thoughts on the best way to go about doing this? The Dropbox API allows for apps to store files on the cloud. What I was thinking was to original store the database (sqlite) for the app on the cloud and then download that database, but I then realized that using that method would make it painfully difficult to merge changes (rather than replacing the whole database). Any thoughts are appreciated. Thanks.
