  • Is there anyway to set values in the settings.bundle from within the APP

    - by joneswah
    Is there any way to set/update values in the settings.bundle from within your app. I am fine reading in values from the preferences into NSUserDefaults but was wondering whether you can set values from within the app. I have a web-app which I am making a iPhone client for and was thinking to include the users account details in the settings.bundle. This is fine if the user only updates the values through the Apple Application Preferences screens, but what if the user updated those values in the web app. I wanted to pull down the values from the web and then "update" the values in the settings.bundle from within the App. I am guessing that this is not possible and that maybe I need to create my own "in-app" settings screen? But thought I would check with you all first ...

  • Is it possible to set an android icon from a drawable in a separate jar?

    - by Rpond
    I want to set a menu option icon for a drawable that is in another jar inside an xml file. <item android:id="@+id/my_location" android:title="My Location" android:icon="@+drawable/my_location"> Instead of drawable/my_location have something like com.somelib.R.drawable.someDrawable. I can set this in onCreateOptionsMenu but was just wondering if it could be done via the xml file.

  • Twitter and Facebook on iPhone - save sessions across app launches?

    - by lostInTransit
    Hi I am using OAuth for twitter and fb-connect for facebook authentication in my iPhone app. Is it possible to save the user sessions across app launches? i.e. if the user logs in once, the next time they launch the app, we log them in automatically from some state saved the last time the app closed? For Twitter would it work if I just save the auth_token and use it every time the user wants to use twitter from my app? Or do I need to do anything else? I could not get it to work like that so wondering if I was doing something wrong. Thanks.

  • Need some help with a join on ContentProviders

    - by Pentium10
    The documentation says Columns from the associated aggregated contact are also available through an implicit join. What's that implicit join? `Join with Contacts` String LOOKUP_KEY read-only See ContactsContract.Contacts String DISPLAY_NAME read-only See ContactsContract.Contacts long PHOTO_ID read-only See ContactsContract.Contacts. int IN_VISIBLE_GROUP read-only See ContactsContract.Contacts. int HAS_PHONE_NUMBER read-only See ContactsContract.Contacts. I am querying ContactsContract.Data, and I need to access as where clauses on the query IN_VISIBLE_GROUP and HAS_PHONE_NUMBER, that are defined in ContactsContract.Contacts. How can I make this possible?

  • iPhone: How do I override the back button in a Navigation Controller?

    - by Angelo Stracquatanio
    Hello, In my app I have a basic Navigation Controller. For all of my views, except one, the controller works as it should. However, for one view in particular, I would like the 'back' button to not go back to the previous view, but to go to one I set. In particular it is going to go back 2 views and skip over one. After doing some research I found that I can intercept the view when it disappears, so I tried to put in code to have it navigate to the page I would like: - (void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; //i set a flag to know that the back button was pressed if (viewPushed) { viewPushed = NO; } else { // Here, you know that back button was pressed mainMenu *mainViewController = [[mainMenu alloc] initWithNibName:@"mainMenu" bundle:nil]; [self.navigationController pushViewController:mainViewController animated:YES]; [mainViewController release]; } } That didn't work, so does anyone have any ideas? Thanks!!

  • 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?

  • Exception if there is IBOutlet in view controller created by initWithNibName

    - by Kail
    When I create a Navigation-based application, the second view controller is created with initWithNibName, if I add a label onto the second view and connect it with IBOutlet in the second view controller. After I navigate to the second view by clicking table cell, and then back to the root view, the application aborts - send message retainCount to a freed object. I know this is caused by the IBOutlet label, which is retained, set nil in viewDidUnload and dealloc in dealloc. But I don't know why, and if I wanna still use IBOutlet, what can I do? Not dealloc it in viewcontroller's dealloc? Anybody could help? Thank you.

  • Will iPhone OS4 make your life easier or harder as a lone app developer?

    - by Matt
    I am interested to hear what people feel about the new iPhone OS4 release. It is obviously very exciting having access to all the new features, apparently (from apple.com) it has over 1500 new APIs. My original thoughts were "Wow, this is awesome", and I suppose it is. I was just getting comfortable with OS 3.2 development though, and now there is a raft of additional stuff to learn in order to keep up with the pack. So I am feeling quite frustrated! Do you think, when working as an individual app developer, having access to these additional features would improve your applications or just water down the quality? I guess being giving the opportunity to improve applications and provide better features should be welcomed. I think frustration comes from struggling to keep up with the continuous changes, but thats the industry we are in I suppose! Any thoughts/comments?

  • How can I stop the iPhone from displaying a transform change until after the screen is redrawn

    - by Ed Marty
    I have found the UIScrollView's zooming mechanism to be clunk and essentially unusable. So instead, I'm rolling my own. I have a UIView that resizes itself with the pinch-zoom, and that's working fine. When the zoom is complete, the view needs to reset its transform and redraw the images. The zoom works essentially in the same way the UIScrollView does. It sets the transform property of the UIView until complete. Then, when the zoom finishes, I want to reset the transform to CGAffineTransformIdentity, resize the frame to be the size it was before, and tell the view to redraw itself at the new size. It all works pretty well, except when I change the transform to identity then redraw the image, there is a slight flicker before the image completely redraws. This is due to the fact that I'm using a subclass of CATiledLayer, since the view can be of arbitrary size. I've overridden the fadeDuration to be zero, but there is still a flicker while the transform is reset before the redraw is finished. Is there any simple way to overcome this without creating another view to draw with then replacing it?

  • 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?

  • Application Design in Interface Builder Challenge

    - by Sheehan Alam
    I want to design an app that launches other sub-apps. Main View will contain 4 buttons. Clicking on each button respectively will launch the other sub-apps. Each sub-app will have a UITabBarController which has its own different views. At any point I want the user to be able to go back to the Main View from any of the sub-apps. I am not sure how to design this in IB.
