  • Ideas for loading initial data in an iPhone application?

    - by Derek Clarkson
    Hi all, In my app I want to load some initial data to show the user how it works. The app uses a CoreData managed sqllite db. SO far I've thought of 3 options: Write code into a class to programmatically create the data. Create a xml file in the apps resources and load through a NSXmlParser whose delegate creates the entries in the sqllite db. Same as option #2, but use a json file and bring in a 3rd party lib to read it. Are there other options I have not found yet? and given that I'm talking about perhaps 6 records per table when there are 3 tables, which would you choose?

  • iPhone Wait For Animation Ending

    - by paul simmons
    Hi, In an iPhone application, I try to catch animation endings using setAnimationDidStopSelector. I try to suspend code execution until animation ends. I have tried this; set a global BOOL variable, set it to TRUE before commiting animation and after commiting animations waited using a while loop. In the setAnimationDidStopSelector, set the BOOL variable to FALSE and hope while loop to break. But unluckily this did not work, the code did not even fall into setAnimationDidStopSelector (I check that with some trace outputs). What do you suggest?

  • How do they do it? Dialogs over home screen.

    - by Brian515
    Hi all, I'm writing an Android application and I would like to place a dialog or view over the home screen so that a user can enter text without jumping into my full application. I can't seem to get this to work. If I present a dialog (even in a transparent activity), my application launches. If you don't know what I'm talking about, take a look at the Facebook widget. I want to replicate a similar behavior to the clicking on the "What's on your mind?" box. Thanks for any help in advance! -Brian

  • Optimal Activity Stack Order for a Main Menu button?

    - by kefs
    I'm developing an app that starts with a main menu, and then continues through three different steps (activities) to a final activity where the task is marked complete. On this last activity, i have several additional options (add note, share, etc..) and i also have a return to main menu button. My question is.. how do i stack the activities so that calling finish() on the final activity will return back to the first activity launched? i am currently just starting the new activity via an intent, so pressing back on this screen doesn't return me to home as i would like. Sorry in advance for being so convoluted in my desc

  • UITable row to add an item

    - by Moshe
    I want to make a TableView of phrases which the user can edit. The "Phrase editor" is being displayed modally. My top left is for the Done button right now. I'm considering making a button at the end of the table for "new phrase". How would I implement that? Is it a good idea to follow the "contacts" application and make a + button in the top right, or Should I make the "Add Items" button at the end of the list? What are HIG implications of either one? BONUS: Where can I find some tutorials on Navigation Controllers and Table Views? Thanks a ton.

  • Rapid taps on an OpenGL ES app introducing input delay

    - by Tim R.
    I am starting out writing a 2D game in OpenGL ES, and I have encountered an odd problem: if I rapidly tap the touchscreen, the input starts lagging behind the display. The more times I tap, the more delay it causes between the input and any indication of that input onscreen. It only happens if I intentionally tap very rapidly, but not from tapping and dragging with any number of fingers. What could be causing this? Excessive details follow: Both accelerometer input and taps are delayed by just tapping. The only events I am responding to are touchesBegan (below) in my EAGLView and accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration in my Game object. There doesn't seem to be any upper limit to the amount of delay: I've gotten up to 12 seconds of delay by tapping rapidly with five fingers. I have not seen any drops in framerate (it stays constantly at 60 fps) in the OpenGL ES tool in Instruments or by taking 1/the time between updates. Possibly relevant code: - (void) drawView:(id) sender { [game update:allTouches]; [renderer render:game]; } -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { allTouches = [event allTouches]; } allTouches is a pointer that gets passed to my Game every update, which passes it to each GameObject in their update methods.

  • Is it possible to tie a subscription to a iTunes account with in-app purhcase?

    - by erotsppa
    We're trying to implement a subscription service with in-app purchase in our app. The problem is our service does not require a user account for the past year of service. Users simply use this service with advertisements shown. We want to give them a subscription where they can buy for say, 3 months to have the advertisement removed. How can this be done? We'll have to make it a consumable because it is a subscription. But we wouldn't know when the subscription end. We can't save the state locally because the user might reinstall the app We can't save the state on the server and tie it to their device because sometimes the user changes device We don't have a user account to tie the subscription to and we don't want to introduce a user account system which spoils the experience. Is there some way of associating the purchase with their iTunes account? So that it is carried with them when they reinstall or changes device?

  • UIWebView - remote html loading local images

    - by AragornSG
    I'm trying to develop an application using UIWebView. The app is loading remote URL's, so in order to make it quick I want it to use the images included in the application bundle. I was wondering if there is a way to do it without forcing the application to manually replace the address of each image to point into local resources?

  • How to modify XML on Objective-C?

    - by Vic
    Hi, I'm working on a project for the iPad, I need to read and write to an xml file, which is also used by the counter part of the application in windows. The problem that I have is that I've been looking around but I haven't found a way to modify an element or attribute in an xml, without having to build the whole xml again. I saw this other post, which is basically the same problem that I have, and I also end it up in the same point as the person asking the question, NSXMLParser and TouchXML are read only and do not allowed me to modify my xml. Any other suggestion about what can I use? Thanks!

  • iPhone: Grouping records in multiple UITableView views

    - by Nic Hubbard
    Let me first say, I know how to create sections and group records within a UITableView. What I am wanting to do is something similar to creating a photo album. So, I have all my data objects coming from core data, and, I want to be able to create a custom group, such as "My Trip to Mexico" and "First Birthday". Then, the user should be able to add objects/records into new sections/albums. So, basically the user is creating custom sections with their own custom names, and then choosing what records should go into that section/album. So, I am just wondering what is the best way to do this? I am thinking that I would just create some extra attributes for my core data model. Or, would I create a whole new "Album Section" object, and somehow use that? Point me in the right direction. :)

  • Universal App won't build for device

    - by Felix Khazin
    I'm trying to get an iPad/iPhone app to run on my iPad. (it builds and runs fine on the simulator) I went through the menu to create a new universal project. Then I added another library that my app will use (route-me), and i keep getting the following linker errors: "___restore_vfp_d8_d15_regs", referenced from: and "___save_vfp_d8_d15_regs", referenced from: I did a search on Google, and found (http://www.badrit.com/blog/2010/6/6/building-route-me-for-ipad) that it's just a matter of matching up project settings in the library projects. I did that but it didn't help. I still keep getting these linker errors. Anyone have any ideas what I can try?

  • How can I draw a shadow beyond a UIView's bounds?

    - by Christian
    I'm using the method described at http://stackoverflow.com/questions/805872/how-do-i-draw-a-shadow-under-a-uiview to draw shadow behind a view's content. The shadow is clipped to the view's bounds, although I disabled "Clip Subviews" in Interface Builder for the view. Is it possible to draw a shadow around a view and not only in a view? I don't want to draw the shadow inside the view because the view would receive touch events for the shadow area, which really belongs to the background.
