  • sqlite issue using WHERE statement on a varchar field in Objective-C

    - by Geykel
    Hi, I have this sql statement SELECT * FROM Language WHERE LanguageCode=? where LanguageCode is a varchar(2). When I use sqlite3-prepare-v2 on that statement I got SQLITE_ERROR but if I use SELECT * FROM Language WHERE LanguageID=? where LanguageID is the primary key numeric identity field the statement compiles just fine. Is there any issue filtering by a varchar field using WHERE statement? Thanks

  • is there a way to disconnect from facebook login without calling logout

    - by Joey
    Basically, I'd like to know how I can logout of my facebook session if I am in an iphone app and have connected to facebook (such that I do not have to repeatedly enter my login/password). Normally you'd disconnect in the app somewhere like in the options, but if this is not available (i.e. anything that triggers the FBSession logout method) is there some other way to do it? I'm guessing one could restore their phone to factory settings or something.

  • How to save objects using Multi-Threading in Core Data?

    - by Konstantin
    I'm getting some data from the web service and saving it in the core data. This workflow looks like this: get xml feed go over every item in that feed, create a new ManagedObject for every feed item download some big binary data for every item and save it into ManagedObject call [managedObjectContext save:] Now, the problem is of course the performance - everything runs on the main thread. I'd like to re-factor as much as possible to another thread, but I'm not sure where I should start. Is it OK to put everything (1-4) to the separate thread?

  • In-app subscription apps

    - by Ron Srebro
    Does anyone know of an app that implemented an in-app subscription? I thought about how the subscription model can be implemented and always ends up with more problems to every possible solution I can think of, so I'm wondering if anyone knows of an app that actually does that. Thanks

  • Advanced Localization with Omission of Arguments in Xcode

    - by coneybeare
    I have this formatted string that I am having a translator work on. ENGLISH "Check out the %1$@ %2$@ in %3$@: %4$@" = "Check out the %1$@ %2$@ in %3$@: %4$@" GERMAN TRANSLATION "Check out the %1$@ %2$@ in %3$@: %4$@" = "Hör Dir mal %2$@ in %3$@ an: %4$@"; These are passed to a [NSString stringWithFormat:] call: ////////////////////////////////////// // Share Over Twitter NSString *frmt = NSLocalizedString(@"Check out the %1$@ %2$@ in %3$@: %4$@", @"The default tweet for sharing sounds. Use %1$@ for where the sound type (Sound, mix, playlist) will be, %2$@ for where the audio name will be, %3$@ for the app name, and %3$@ for where the sound link will be."); NSString *urlString = [NSString stringWithFormat:@"sounds/%@", SoundSoundID(audio)]; NSString *url = ([audio audioType] == UAAudioTypeSound ? UrlFor(urlString) : APP_SHORTLINK); NSString *msg = [NSString stringWithFormat: frmt, [[Audio titleForAudioType:[audio audioType]] lowercaseString], [NSString stringWithFormat:@"\"%@\"", AudioName(audio)], APP_NAME, url]; NSString *applink = [NSString stringWithFormat:@" %@", APP_SHORTLINK]; if (msg.length <= (140 - applink.length)) { msg = [msg stringByAppendingString:applink]; } returnString = msg; With the desired and actual outcome of: ENGLISH desired: "Check out the sound "This Sound Name" in My App Name: link_to_sound link_to_app" actual: "Check out the sound "This Sound Name" in My App Name: link_to_sound link_to_app" GERMAN desired: "Hör Dir mal "This Sound Name" in My App Name an: link_to_sound link_to_app" actual: "Hör Dir mal sound in "This Sound Name" an: My App Name link_to_app" THE PROBLEM The problem is that I was under the assumption that by using numbered variable in the NSLocalizedString, I could do things like this, where the %1$@ variable is completely omitted. If you notice, the German translation of the format string does not use the first argument (%1$@) at all but it ("sound") still appears in the output string. What am I doing wrong?

  • Android Set ImageButton as Toggle

    - by GuyNoir
    How can I have an imagebutton stay in the 'pressed' state when it is clicked? Basically I just want the background to be the depressed background, but I can't figure out how to set it. At the moment, I've just copied the selected button background into my res folder, but when I set it as the background, it becomes blurry (since the original image is bigger than the button itself). Normal Background: What I'm getting:

  • How to fix IllegalStateException error when trying to update a listview?

    - by Michael Vetrano
    Hi guys, I am trying to get this code to run, but I get an IllegalStateException when I run this code saying that the content of the listview wasn't notified, yet I have a notification upon updating the data. This is a custom listview adapter. Here is the relevant part of my code: class LoadingThread extends Thread { public void run() { int itemsOriginallyLoaded = 0; synchronized( items ) { itemsOriginallyLoaded = items.size(); } for( int i = itemsOriginallyLoaded ; i < itemsToLoad ; ++i ) { Log.d( LOG_TAG, "Loading item #"+i ); //String item = "FAIL"; //try { String item = "FAIL"; try { item = stockGrabber.getStockString(dataSource.get(i)); } catch (ApiException e) { Log.e(LOG_TAG, "Problem making API request", e); } catch (ParseException e) { Log.e(LOG_TAG, "Problem parsing API request", e); } //} catch (ApiException e) { // Log.e(TAG, "Problem making API request", e); //} catch (ParseException e) { // Log.e(TAG, "Problem parsing API request", e); //} synchronized( items ) { items.add( item ); } itemsLoaded = i+1; uiHandler.post( updateTask ); Log.d( LOG_TAG, "Published item #"+i ); } if( itemsLoaded >= ( dataSource.size() - 1 ) ) allItemsLoaded = true; synchronized( loading ) { loading = Boolean.FALSE; } } } class UIUpdateTask implements Runnable { public void run() { Log.d( LOG_TAG, "Publishing progress" ); notifyDataSetChanged(); } }

  • How can I get the main thread to sleep while waiting for a delgate to be called?

    - by Erik B
    Consider a class with these methods: - (id) initWithFrame: (CGRect) frame { if (!(self = [super init])) return nil; webView = [[UIWebView alloc] initWithFrame:frame]; [webView setDelegate:self]; lock = [[NSConditionLock alloc] initWithCondition:LOCK_WAIT]; return self; } - (void) setHTML: (NSString *) html { [lock lockWhenCondition:LOCK_WAIT]; [webView loadHTMLString:html baseURL:nil]; [lock unlock]; } - (void)webViewDidFinishLoad:(UIWebView *)aWebView { [lock lockWhenCondition:LOCK_WAIT]; // Locking to be able to unlock and change the condition. [lock unlockWithCondition:LOCK_GO]; } - (NSString *) stringByEvaluatingJavaScriptFromString: (NSString *) jsCommand { [lock lockWhenCondition:LOCK_GO]; return [webView stringByEvaluatingJavaScriptFromString:jsCommand]; [lock unlock]; } Let's call this class SynchronousUIWebView. From the main thread I execute: webView = [[SynchronousUIWebView alloc] initWithFrame:frame]; [webView setHTML:html]; [webView stringByEvaluatingJavaScriptFromString:jsCommand]; The problem seems to be that the delegate is not called until I leave the current call stack, which I don't since I'm waiting for the delegate call to happen, aka deadlock. To me it seems like the delegate call is pushed to a queue that is called when the current call is done. So the question is can I modify this behavior? Note: The reason this is needed is that I can't execute the JavaScript until the HTML has loaded.

  • Core Data: fetch an NSManagedObject by its properties

    - by niklassaers
    Hi guys, I have an object NetworkMember that has no attributes but is defined by its relationships Person, Network, Level and Role. In my app, I've found all the four relationships, but I want to make sure not to double-register my NetworkMember, thus I'd like to search for this NSManagedObject before instantiating it. How should I write a query that queries for an NSManagedObject just consisting of relationships? Cheers Nik

  • Working with iPhone OS 3.2 only classes

    - by user324881
    How would you write a universal app that uses classes introduced in iPhone OS 3.2, such as UIPopoverController and UISplitViewController? On Jeff LaMarche's blog about this, Ole provides a method for instantiating these objects; you would instantiate a UIPopoverController like so: [NSClassFromString(@"UIPopoverController") alloc]. This is fine for instantiating these classes in code but what about protocols and their methods? My iPad app uses a UISplitViewController and has a class that needs to conform to the UISplitViewControllerDelegate and UIPopoverControllerDelegate. How would you declare this? And how would you work with a method such as the following? - (void)splitViewController:(UISplitViewController *)svc willHideViewController:(UIViewController *)aViewController withBarButtonItem:(UIBarButtonItem *)barButtonItem forPopoverController:(UIPopoverController *)pc where the method call requires UISplitViewController to be passed in?

  • How to prevent modal view controllers flashing when changing

    - by KP Overflow
    I have three view controllers, let's call them A, B and C. When a button is pressed on view A, view B is shown using presentModalViewController:animated: When the finish button is pressed on screen B, it dismisses itself. View A is notified whereupon it immediately shows view C, again using presentModalViewController:animated: The problem is that view A's content is momentarily flashed on the screen between view B closing and view C opening. I can get around this by making view A blank and moving it's current content to a new view, D. (For various reasons, I don't want view B to own view C, that's why it's not opening it) Am I over-complicating this? I'm sure there is a smarter way to go? ThanksT

  • How to get orientation of android from gyrsocope sensor events ?

    - by Pritam
    I am using android 2.3 on Nexus S and want to get orientation from gyroscope sensor events. As gyro gives angular velocity how to use this for getting device orientation ? Also is there any way we can get pure linear accelerations on phone's axis, without gravity vector. I expected this from Linear acceleration sensor event but just found a post and referred android source as well for Sensor which currently uses only accelerometer. So what's the best way to combine the readings from both hardware to get pure accelerations without gravity inclusions ? Thanks.

  • Android: Saving custom button and spinner

    - by Jacob Huggart
    Hello All, I am new to Android programming and was handed a fairly large program that is almost complete, but needed support for switching between portrait and landscape view. I added android:configChanges="keyboardHidden|orientation" to the manifest and used onConfigurationChanged to save the view data and that works. However, there is a button that displays the date selected (when pressed a calendar to select the date comes up) and a spinner that displays the current view and is used to select a new view. Those two items are being cleared/reset and do not work at all after the screen flip. I have been attempting to use onSaveInstanceState and onRestoreInstanceState to fix that, but I cannot figure out how to get it to work. Any advice?

  • iPhone TabbarController Switch Transition

    - by user269737
    I've implemented gestures (touchBegan-moved-ended) in order to allow for swiping through my tabs. It works. I'd like to add a slide-from-left and slide-from-right transition. It would be better if it could be part of the gesture if statement which tells me if the swipe is towards the right of left. Since I determine which tab is displayed from that, I could show that specific transition along with the new tab. So my question is this: what's the simplest way to simplement a slide transition at a specific instance. I don't want it to be for the whole tabbarcontrol since this is specifically for the swiping. Thanks for the help, much appreciated. For clarification purposes, this is snippet shows how I'm switching tabs: if(abs(diffx / diffy) > 2.5 && abs(diffx) > HORIZ_SWIPE_DRAG_MIN) { // It appears to be a swipe. if(isProcessingListMove) { // ignore move, we're currently processing the swipe return; } if (mystartTouchPosition.x < currentTouchPosition.x) { isProcessingListMove = YES; self.tabBarController.selectedViewController = [self.tabBarController.viewControllers objectAtIndex:0]; return; } else { isProcessingListMove = YES; self.tabBarController.selectedViewController = [self.tabBarController.viewControllers objectAtIndex:1 ]; return; }

  • How much difference you find between scrollview offset and contentview offset of table?

    - by neha
    Hi all, In my application, I want to detect the end of the entire table with scrollview. Since there're no sections in my scrollview, I'm using noOfRows*rowHeight to reach the end. I'm using scrollview.contentOffset.y to detect the y offset, but this contentOffset isn't matching the multiplication result i.e. I have 20 rows and with height as 250. So it comes as 5000, but my scrollview.offset.y at the end of last cell is nearly about 4650. What's this difference? Thanx in advance.

  • Can a variable bu used 2nd time after releasing it?

    - by Jakub
    Hello, I try to understand the memory management in ObjectiveC and still some things are a misery for me. I've got an instance variable: NSMutableArray *postResultsArray; when a button is clicked in the UI I create new array: self.postResultsArray = [NSMutableArray array]; then I add some objects to the array and when the whole operation is done I would like to release the array: [self.postResultsArray release]; (I assume that all the objects stoed in the array will be released along with the array). The problem appears when I click the button again and in the code I want to create the array again with: self.postResultsArray = [NSMutableArray array]; I get: [CFArray release]: message sent to deallocated instance 0x3d9e390 Can't I initialize the same instance variable for the second time? or maybe I should not release it? and if so, why? Thanks!

  • Android WVGA800 and 854

    - by Droidy
    Although my relativelayout looks very similar on WVGA800 and WVGA854 on the emulator, theres different spacing on some of the objects because I'm going off of marginleft or marginright. Since the 854 is a greater width, its pushing some objects differently. Is there any way I could target either one to adjust for the different margins?
