  • How can I tell if the screen is on in android?

    - by user297020
    In Android 2.2 (Level 7) the function PowerManager.IsScreenOn() returns a boolean that is true if the screen is turned on and false if the screen is turned off. I am developing code for Android 1.5 (Level 3). How do I accomplish the same task in older versions of Android? I do not want to turn the screen on or off in my code. I just want to know what it is.

  • Android - Debugging on device

    - by teepusink
    Hi, How do I install the app that I'm making on an actual device? I'm on Mac Snow Leopard with a Nexus One phone and I've followed the steps here http://developer.android.com/intl/zh-TW/guide/developing/device.html So I added: 1. android:debuggable="true" 2. Turn on "USB Debugging" on your device. However, when I go to the terminal and do "adb devices" only the emulator shows up there. I'm supposed to see my device name too right? What am I missing? Thanks, Tee

  • Designing the iPhone interface in a nib or in code?

    - by Jacob Relkin
    I've been pondering over this question for a long time already. On the one hand, Interface Builder offers a really easy way to design the interface and wire the elements up with objects in code. On the other hand, in larger projects, Interface Builder becomes a hassle to maintain. Any suggestions would be greatly appreciated.

  • iphone file download not working

    - by Anonymous
    Hi, In my app I 'm first connecting to a web service, which in return sends a url for a file. I use the url to download the file and then display it on the new view. I get the correct URL but not able to download file from that location. I have another test app which will download file from the same location and it works like a charm. following is my code for webservice-file download. This is a snippet of the code where i 'm parsing the web service xml and then pass the result to NSData for file download. Any suggestions where am i going wrong -- I 'm referring to the following tutorials. Web Service PDF Viewer if ([elementName isEqualToString:@"PRHPdfResultsResult"]) { NSLog(soapResults); UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Report downloaded from:" message:soapResults delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; NSData *pdfData = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:soapResults]]; //Store the Data locally as PDF File NSString *resourceDocPath = [[NSString alloc] initWithString:[[[[NSBundle mainBundle] resourcePath] stringByDeletingLastPathComponent] stringByAppendingPathComponent:@"Documents"]]; NSString *filePath = [resourceDocPath stringByAppendingPathComponent:@"myPDF.pdf"]; [pdfData writeToFile:filePath atomically:YES]; [alert show]; [alert release]; [soapResults setString:@""]; elementFound = FALSE; }

  • What's the best approach for modifying PDF interactive form fields on iOS?

    - by gbreen
    I've been doing some head banging on this one and solicit your advice. I am building an app that as part of it's features is to present PDF forms; meaning display them, allow fields to be changed and save the modified PDF file back out. UIWebViews do not support PDF interactive forms. Using the CGPDF apis (and benefit from other questions posted here and elsewhere), I can certainly present the PDF (without the form fields/widgets), scan and find the fields in the document, figure out where on the screen to draw something and make them interactive. What I can't seem to figure out is how to change the CGPDFDictionary objects and write them back out to a file. One could use the CGPDF Apis to create a new PDF document from whole cloth, but how do you use it to modify an existing file? Should I be looking elsewhere such as 3rd party PDF libs like PoDoFo or libHaru? I'd love to hear from anyone who has successfully modified a PDF and written it back out as to your approach. Thanks!

  • Zooming to UIView and it's sub-views

    - by leon
    Hi, I have a UIView which I can zoom to (as it is set as a subview of UIScrollView). UIView has UILabel, UITextField, etc. If I just zoom to the UIView, then of course label and text field get fuzzy (the same effect if you are zooming to the image file without changing image resolution). To solve the problem I need to increase the font size and sizes of the UILable and UITextField in according to the scale used to zoom in (scale is passed as a param by the UIScrollView). This is where I am getting confused. Changing frame (by increasing it width and height by zooming scale) I get all my elements (sub-views) repositions (because changing frame effects center and bounds) Question: 1. What would I need to do to zoom in to the sub-views and just increase the sub-view sizes while keeping them in the exactly the same position? thanks

  • Creating a unique id for a Core Data program on the iPhone

    - by Big Twisty
    I am fairly new at programming in Objective-C, having been a windows programmer since I was a kid. I am falling in LOVE with it. I am, however, having a bit of trouble figuring out this Core Data stuff. How do I create a new entry with a unique ID? In SQL I would just declare one field as an autoincrement field. I'm not seeing anything like that here, but I could just be missing something. I just want an auto incrementing NSInteger field, so when I manually add items to the database, I will have some form of reference to them.

  • UITableViewCell checkmarks

    - by burki
    Hi! When you select a cell in the UITableView, the - (void)tableView:(UITableView *)table didSelectRowAtIndexPath:(NSIndexPath *)indexPath is called. There some of the NSManagedObjects will be updated with the right values and the row will be deselected. Well, it works all right, but you can't see any selection of the tableviewcell. I found out that the access on core data causes the problem, that means, if i comment out the lines with the commands of updating the NSManagedObjects, it all works like I want, with a smooth selection and deselection. Can anybody help? Thanks. - (void)tableView:(UITableView *)table didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //[table deselectRowAtIndexPath:indexPath animated:YES]; NSMutableSet *favoriteGroups = [NSMutableSet setWithSet:element.favoriteGroup]; NSMutableSet *elements = [NSMutableSet setWithSet:[(FavoriteGroup *)[fetchedResultsController objectAtIndexPath:indexPath] element]]; UITableViewCell *checkedCell = [table cellForRowAtIndexPath:indexPath]; if (checkedCell.accessoryType == UITableViewCellAccessoryCheckmark) { [elements removeObject:element]; [favoriteGroups removeObject:[fetchedResultsController objectAtIndexPath:indexPath]]; [[table cellForRowAtIndexPath:indexPath] setAccessoryType:UITableViewCellAccessoryNone]; } else { [elements addObject:element]; [favoriteGroups addObject:[fetchedResultsController objectAtIndexPath:indexPath]]; [[table cellForRowAtIndexPath:indexPath] setAccessoryType:UITableViewCellAccessoryCheckmark]; } element.favoriteGroup = favoriteGroups; FavoriteGroup *favoriteGroup = [self.fetchedResultsController objectAtIndexPath:indexPath]; favoriteGroup.element = elements; [self.tableView deselectRowAtIndexPath:indexPath animated:YES]; }

  • Localization not working

    - by Krumelur
    I have an application that is supposed to be localized (two languages, english being the default). However, I seem to only get the English versions of all strings, regardless of what the system default language is. I am probably missing something trivial, but I've read several tutorials now without any solution. I added this line to main(), NSLog(@"Current locale is: %@", [[NSLocale currentLocale] localeIdentifier]); and the resulting printout is en_US, while the system was set to use the localized language. I checked the build output, and the app bundle contains the XX.lproj folders as I believe they should (and they are UTF-16, I confirmed this). What am I missing?

  • Launch an app from within another (iPhone)

    - by Jeff
    Is it possible to launch any arbitrary iPhone application from within another app? For example in my application if I want the user to push a button and launch right into the Phone app (close the current app, open the Phone app), would this be possible? I know this can be done for making phone calls with the tel URL link, but I want to instead just have the Phone app launch without dialing any specific number.

  • 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?

  • NSArray vs. SQLite for Complex Queries on iPhone

    - by GingerBreadMane
    Developing for iPhone, I have a collection of points that I need to make complex queries on. For example: "How many points have a y-coordinate of 10" and "Return all points with an X-coordinate between 3 and 5 and a y-coordinate of 7". Currently, I am just cycling through each element of an NSArray and checking to see if each element matches my query. It's a pain to write the queries though. SQLite would be much nicer. I'm not sure which would be more efficient though since a SQLite database resides on disk and not in memory (to my understanding). Would SQLite be as efficient or more efficient here? Or is there a better way to do it other than these methods that I haven't thought of? I would need to perform the multiple queries with multiple sets of points thousands of times, so the best performance is important.

  • Add subview to another view

    - by Martol1ni
    With two ViewControllers, MyView 1 and MyView 2, is there possible to add a subview to MyView2 from MyView1.m? I have tried: MyView2 * screen = [[MyView2 alloc]initWithNibName:nil bundle:nil]; [screen.view addSubView:mySubView]; But my new instance of MyView 2 has no connection to the 'visible' ViewController on MyView2, right? To clarify, the ViewController that is showing, is MyView1. I want MyView1 to be able to add a subview to the MyView2 view. Thanks

  • 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.
