  • UITextField in UIAlertView doesn't respond to cut/copy/paste on second showing

    - by Jesse Grosjean
    Edit Reposting... I accidentally marked my previous question as "commuity wiki" and didn't realize that answers to wiki posts don't generate reputation. I"m adding a UITextView to a UIAlertView with the following code: UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Enter Name Here" message:@"this gets covered!" delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:@"OK!", nil]; UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12, 45, 260, 25)]; CGAffineTransform myTransform = CGAffineTransformMakeTranslation(0, 60); [alert setTransform:myTransform]; [myTextField setBackgroundColor:[UIColor whiteColor]]; [alert addSubview:myTextField]; [alert show]; [alert release]; [myTextField release]; If I place that code in a standard action method: (IBAction)testAlertView:(id)sender { ...the above code... } Then the first time I show the UIAlertView the cut/copy/paste popup menu will show in UITextField that's been added to the UIAlertView. (For instance if I tap and hold, then "Paste" will popup after I release. The problem is after working correctly the first time, none of the cut/copy/paste buttons will show up again next time I show the UIAlertView (new instance) unless I restart the app. Does anyone know why, or how to fix this problem? Bonus information I just found out that I can get things to always work if I create an show the alert within a UIActionSheet delagate callback. For instance this always works (cut/copy/paste always shows up when in the UITextField when appropriate) (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { ...the above code... } Any idea what might be happening in this second case that make things work? I don't want to use a UIActionSheet in my app, so I'd like to find a way to make it work from a plain old action method. Thanks, Jesse

  • IComparer using Lambda Expression

    - by josephj1989
    class p { public string Name { get; set; } public int Age { get; set; } }; static List<p> ll = new List<p> { new p{Name="Jabc",Age=53},new p{Name="Mdef",Age=20}, new p{Name="Exab",Age=45},new p{Name="G123",Age=19} }; protected static void SortList() { IComparer<p> mycomp = (x, y) => x.Name.CompareTo(y.Name); <==(Line 1) ll.Sort((x, y) => x.Name.CompareTo(y.Name));<==(Line 2) } Here the List.sort expects an IComparer<p> as a parameter. And it works with the lambda as shown in Line 2. But when I try to do as in Line 1, I get an error: Cannot convert lambda expression to type System.Collections.Generic.IComparer' because it is not a delegate type I investigated this for quite some time but I still don't understand it. Maybe my understanding of IComparer is not quite good.

  • iPhone Development - CLLocationManager vs. MapKit

    - by Mustafa
    If i want to show userLocation on the map, and at the same time record the user's location, is it a good idea to add an observer to userLocation.location and record the locations, OR should i still use CLLocationManager for recording user location and use mapView.showUserLocation to show the user's current location (blue indicator)? I want to show the default blue indicator supported by the MapKit API. Also, here's a rough sample code: - (void)viewDidLoad { ... locationManager = [[CLLocationManager alloc] init]; locationManager.desiredAccuracy = kCLLocationAccuracyBest; locationManager.distanceFilter = DISTANCE_FILTER_VALUE; locationManager.delegate = self; [locationManager startUpdatingLocation]; myMapView.showUserLocation = YES; [myMapView addObserver:self forKeyPath:@"userLocation.location" options:0 context:nil]; ... } - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { // Record the location information // ... } - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { NSLog(@"%s begins.", __FUNCTION__); // Make sure that the location returned has the desired accuracy if (newLocation.horizontalAccuracy <= manager.desiredAccuracy) return; // Record the location information // ... } Under the hood, i think MKMapView also uses CLLocationManager to get user's current location? So, will this create any problems because i believe both CLLocationManager and MapView will try to use same location services? Will there be any conflicts and lack of accurate/required or current data?

  • UIImageWriteToSavedPhotosAlbum with malloc_error

    - by lbalves
    I have an NIB file with a button. When I click this button, the setWallpaper: selector is called. Everything works as expected (the image is saved), excepte by the error thrown by malloc. malloc: *** error for object 0x184d000: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug I've set a breakpoint at malloc_error_break, but I don't understand anything from the debugger. I couldn't even find the object 0x184d000. Does anyone know why is this happening? I had also tried to retain the UIImage before sending it to UIImageWriteToSavedPhotosAlbum, but without success. My code is below: - (IBAction)setWallpaper:(id)sender { UIImage *image = [UIImage imageNamed:@"wallpaper_01.png"]; UIImageWriteToSavedPhotosAlbum(image, self, @selector(image:didFinishSavingWithError:contextInfo:), nil); } - (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo { UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"Galo!!!",@"Saved image message: title") message:NSLocalizedString(@"Now, check your \"saved photos\" group at \"photos\" app in your iPhone and select the actions menu > set as wallpaper.",@"Saved image message") delegate:nil cancelButtonTitle:NSLocalizedString(@"OK",@"OK Button") otherButtonTitles:nil]; [alertView show]; [alertView release]; }

Please tell me if some one have any idea how to get the accessory work again. Thanks in advance.

  • UIImagePickerController does nothing when using camera after I hit "Use" button

    - by wgpubs
    Code below. When I hit the "Use" button after taking a picture ... the application becomes totally unresponsive. Any ideas what I'm doing wrong? The "addPlayer:" method is called when a button is pressed on the UIViewController's view. Thanks - (IBAction) addPlayers: (id)sender{ // Show ImagePicker UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; imagePicker.delegate = self; // If camera is available use it and display custom overlay view so that user can add as many pics // as they want without having to go back to parent view if([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera]) { imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera; } else { imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; } [self presentModalViewController:imagePicker animated:YES]; [imagePicker release]; } - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { // Grab original image UIImage *photo = [info objectForKey:UIImagePickerControllerOriginalImage]; // Resize photo first to reduce memory consumption [self.photos addObject:[photo scaleToSize:CGSizeMake(200.0f, 300.0f)]]; // Enable *PLAY* button if photos > 1 if([self.photos count] > 1) btnStartGame.enabled = YES; // Update player count label lblPlayerCount.text = [NSString stringWithFormat:@"%d", [self.photos count]]; // Dismiss picker if not using camera picker dismissModalViewControllerAnimated:YES]; }

  • iOS 5.0 AVAudioPlayer Error loading audio clip: The operation couldn’t be completed. (OSStatus error -50.)

    - by Jason Catudal
    So I'm trying to test out the audio player on the iPhone, and I went off Troy Brant's iOS book. I have the Core Audio, Core Foundation, AudioToolbox, and AVFoundation frameworks added to my project. The error message I get is in the subject field. I read like 20 pages of Google search results before resorting to asking here! /sigh. Thanks if you can help. Here's my code, pretty much verbatim out of his book: NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:@"Yonah" ofType:@"caf"]; NSLog(@"%@", soundFilePath); NSURL *fileURL = [NSURL URLWithString:soundFilePath]; NSError *error; audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:&error]; if (!error) { audioPlayer.delegate = self; //audioPlayer.numberOfLoops = -1; [audioPlayer play]; } else { NSLog(@"Error loading audio clip: %@", [error localizedDescription]); } EDIT: Holy Shinto. I figured out what it was. I changed NSURL *fileURL = [NSURL URLWithString:soundFilePath]; to NSURL *fileURL = [NSURL fileURLWithPath:soundFilePath]; to the latter and I was getting a weird error, weirder than the one in the subject BUT I googled that and I changed my OS input device from my webcam to my internal microphone and guess what, it worked under the fileURLWithPath method. I'll be. Damned.

  • Access denied when trying to read information about SharePoint groups

    - by strongopinions
    I am trying to get the membership of a group in WSS 3.0. I am doing this in an elevated permissions block. Here is the code: SPSecurity.RunWithElevatedPrivileges(delegate() { using (SPSite site = new SPSite(SPContext.Current.Site.ID)) { using (SPWeb rootWeb = site.RootWeb) { SPGroup gAdmins = rootWeb.SiteGroups["Admins"]; } } }); I get taken to the "access denied" SharePoint screen when I run this code. The group exists. The identity of the application pool for the web application is in the dbo role in the content database. The code works on my development server, but not on another server, which leads me to believe there is something wrong with the permissions or configuration on this server, maybe something in dcomcnfg? Here are some lines from the SharePoint log that seem to be related: PermissionMask check failed. asking for 0x08000000, have 0x00000000 Unknown SPRequest error occurred. More information: 0x80070005 Access Denied for /Pages/UserAdmin.aspx.

  • Dismissing iPad UIPopoverController from within it's content controller

    - by joshholat
    So I have a popover with a button in it. When that button is pushed, I want the popover to go away. It seems easy enough, but I can't figure it out for the life of me. The code I use to show the popover is below: AddCategoryViewController* content = [[AddCategoryViewController alloc] init]; UIPopoverController* aPopover = [[UIPopoverController alloc] initWithContentViewController:content]; aPopover.delegate = self; [content release]; // Store the popover in a custom property for later use. self.addCategoryPopover = aPopover; [aPopover release]; [addCategoryPopover presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES]; Within the addcategoryviewcontroller, I have: -(IBAction)saveAddCategory:(id)sender { if (rootViewController == nil) rootViewController = [[RootViewController alloc] init]; [rootViewController.addCategoryPopover dismissPopoverAnimated:YES]; [rootViewController dismissPopover]; } Rootviewcontroller is where the popover is being created from. Unfortunately, neither of those methods work to dismiss it. any help?

  • How to use drag and drop within a UIScrollView

    - by user249488
    I am trying to drag and drop UIViews within a UIScrollView. I'd like the UIScrollView to scroll if I drag a UIView so that it intersects the top or bottom of the ScrollView. If it touches the top, it should scroll up. If it touches the bottom, it should scroll down. Once the UIView is moved such that it is no longer intersecting the top or bottom, the scrolling should stop. The first approach I tried was to start an NSTimer whenever I detected that the UIView intersected with the top or bottom of the scrollview. The timer would scroll the UIScrollView bit by bit until it was invalidated. This resulted in very jerky scrolling, since there is no way to predict when the timers will fire. My current approach is to simply scroll all the way to the top or bottom of the ScrollView, like this: [UIView beginAnimations:nil context:NULL]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [UIView setAnimationDuration:1.0]; [self.parentScrollview setContentOffset:newOffset animated:NO]; [UIView commitAnimations]; In order to stop scrolling, I try to determine the position of the touch in the touchesMoved: delegate, and use that to calculate the contentOffset to use for the scrollView. The problem is, when I try to get the location in the view via [[touches anyObject] locationInView:self], I get the final end location, rather than the current location. I'm guessing that's because the contentOffset on the scrollView is set immediately. Is there a way to get the actual location of a touch in a situation like this? Or any other way to set the contentOffset when I interrupt the scrolling animation?

  • UIImage cropping on user selected rectangle in iphone?

    - by Rajendra Bhole
    Hi, I developing an small application in which i want to crop the UIImage captured by imagePickerControllerSourceTypeOfCamera. The UIImage should crop by user selected crop area or cropped rectangle. That means first user capture the image from the camera.Then on captured image the user selected an rectangle having color gray.That image(image data) should crop from that gray colored rectangle. My under develop code is as follows. -(IBAction) getPhoto:(id)sender { UIImagePickerController* imagePickerController = [[UIImagePickerController alloc] init]; imagePickerController.delegate = self; if((UIButton *) sender == btnphotoAlbum) { imagePickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; } else { imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera; } imagePickerController.allowsImageEditing = YES; //imagePickerController.toolbar.barStyle =UIBarStyleBlackOpaque; //UIToolbar *toolBar=[[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 20, 320)]; //imagePickerController.

  • Can I tell Castle Windsor to create a component in a separate AppDomain?

    - by Michael L Perry
    I've created a multi-threaded service that uses Castle Windsor to create components to run on separate threads. I Resolve an component by name with parameters for each thread. I'm running into concurrency problems with a 3rd party library used by the components. I suspect that isolating those components in separate AppDomains will resolve the problem. Is there a way to have Resolve create the component using a different AppDomain? private ActivityThread NewActivityThread(ActivityInstance activityInstance) { // Set up the creation arguments. System.Collections.IDictionary arguments = new Dictionary<string, string>(); activityInstance.Parameters.ForEach(p => arguments.Add(p.Name, p.Value)); // Get the activity handler from the container. IActivity activity = Program.Container.Resolve<IActivity>(activityInstance.Name, arguments); // Create a thread for the activity. ActivityThread thread = new ActivityThread(activity, activityInstance, _nextActivityID++); return thread; } public ActivityThread(IActivity activity, ActivityInstance instance, int id) { _activity = activity; _instance = instance; _id = id; } public void Start() { if (_thread == null) { // Create a new thread to run this activity. _thread = new Thread(delegate() { _activity.Run(); }); _thread.Name = _activity.ToString(); _thread.SetApartmentState(ApartmentState.STA); _thread.Start(); } }

  • Integrating Dynamics CMS with Sharepoint ASCX SecurityException Issue

    - by Gavin
    Hi, I've an ASCX control (WebParts aren't used in this solution) which interrogates CMS 4's data via the API provided by Microsoft.Crm.Sdk and Microsoft.Crm.SdkTypeProxy. The solution works until it's deployed to Sharepoint. Initially I received the following error: [SecurityException: That assembly does not allow partially trusted callers.] MyApp.SharePoint.Web.Applications.MyAppUtilities.RefreshUserFromCrm(String login) +0 MyApp.SharePoint.Web.Applications.MyApp_LoginForm.btnLogin_Click(Object sender, EventArgs e) +30 System.Web.UI.WebControls.Button.OnClick(EventArgs e) +111 Then I tried wrapping the calling code in the ASCX with SPSecurity.RunWithElevatedPrivileges: SPSecurity.RunWithElevatedPrivileges(delegate() { // FBA user may not exist yet or require refreshing MyAppUtilities.RefreshUserFromCrm(txtUser.Text); }); But this resulted in the following error: [SecurityException: Request for the permission of type 'Microsoft.SharePoint.Security.SharePointPermission, Microsoft.SharePoint.Security, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' failed.] MyApp.SharePoint.Web.Applications.MyApp_LoginForm.btnLogin_Click(Object sender, EventArgs e) +0 System.Web.UI.WebControls.Button.OnClick(EventArgs e) +111 When I elevate the trust level in the Sharepoint site to full everything works fine, however I need to come up with a solution that uses minimal trust (or a customised minimal trust). I'm also trying to stay clear of adding anything to the GAC. Any ideas? I assume the issue is occuring when trying to call functionality from Microsoft.Crm.* Thanks in advance for any help anyone can provide. Cheers, Gavin

  • How to handle correctly HTTP Digest Authentication on iPhone

    - by Fabiano Francesconi
    Hello guys. I'm trying to upload a file onto my personal server. I've written a small php page that works flawlessy so far. The little weird thing is the fact that I generate all the body of the HTTP message I'm going to send (let's say that amounts to ~4 mb) and then I send the request to my server. The server, then, asks for an HTTP challenge and my delegate connection:didReceiveAuthenticationChallenge:challenge replies to the server with the proper credentials and the data. But, what's happened? The data has been sent twice! In fact I've noticed that when I added the progressbar.. the apps sends the data (4mb), the server asks for authentication, the apps re-sends the data with the authentication (another 4mb). So, at the end, I've sent 8mb. That's wrong. I started googling and searching for a solution but I can't figure out how to fix this. The case scenarios are two (my guess): Share the realm for the whole session (a minimal HTTP request, then challenge, then data) Use the synchronized way to perform an HTTP connection (things that I do not want to do since it seems an ugly way to handle this kind of stuff to me) Thank you

  • iPhone - openAL stops playing if I record with AVAudioRecorder

    - by Oscar Peli
    Hi there, this is an iPhone-related question: I use openAL to play some sound (I have to manage gain, pitch, etc.). I want to record what I'm playing and I use AVAudioRecorder but when I "prepareToRecord" openAL stops to play audio. What's the problem? Here is the record IBAction I use: - (IBAction) record: (id) sender { NSError *error; NSMutableDictionary *settings = [NSMutableDictionary dictionary]; [settings setValue: [NSNumber numberWithInt:kAudioFormatLinearPCM] forKey:AVFormatIDKey]; [settings setValue: [NSNumber numberWithFloat:8000.0] forKey:AVSampleRateKey]; [settings setValue: [NSNumber numberWithInt: 1] forKey:AVNumberOfChannelsKey]; [settings setValue: [NSNumber numberWithInt:16] forKey:AVLinearPCMBitDepthKey]; [settings setValue: [NSNumber numberWithBool:NO] forKey:AVLinearPCMIsBigEndianKey]; [settings setValue: [NSNumber numberWithBool:NO] forKey:AVLinearPCMIsFloatKey]; NSURL *url = [NSURL fileURLWithPath:FILEPATH]; self.recorder = [[AVAudioRecorder alloc] initWithURL:url settings:settings error:&error]; self.recorder.delegate = self; self.recorder.meteringEnabled = YES; [self.recorder prepareToRecord]; [self.recorder record]; } Thanks

  • Fully-loaded UIViewController losing all it's data after adding to scroll view

    - by clozach
    Summary I'm repurposing Apple's Page Control project. In loadScrollViewWithPage:, the view controllers that I'm adding to the scroll view appear on screen without their initialized values, as if displayed directly from the nib. Specifics Here's the code that appears to be working when I step through it: CBFullScreenViewController *controller = [viewControllers objectAtIndex:page]; if ((NSNull *)controller == [NSNull null]) { controller = [[CBFullScreenViewController alloc] init]; // Populate the view from the corresponding CBImage object CBImage *imageObject = [imageArray objectAtIndex:page]; BOOL bookmarked = [imageObject.bookmarked boolValue]; controller.bookmarkButton.highlighted = bookmarked; NSString *subtitle = imageObject.subtitle; controller.closedSubtitleLabel.text = subtitle; // <-- snip...more initialization --> // controller.delegate = self; [viewControllers replaceObjectAtIndex:page withObject:controller]; [controller release]; } // add the controller's view to the scroll view if (nil == controller.view.superview) { CGRect frame = scrollView.frame; frame.origin.x = frame.size.width * page; frame.origin.y = 0; controller.view.frame = frame; [scrollView addSubview:controller.view];//<< controller and subviews } // all have non-null, seemingly // valid values at this point Here's the init method in CBFullScreenViewController: - (id)init { if ((self = [super initWithNibName:@"CBFullScreenViewController" bundle:nil])) { self.cover = [[UIImageView alloc] init]; self.homeButton = [[UIButton alloc] init]; self.tabView = [[UIButton alloc] init]; self.closedSubtitleLabel = [[UILabel alloc] init]; self.openSubtitleLabel = [[UILabel alloc] init]; // <-- snip...more initialization --> // } return self; } While troubleshooting this for the last 2 hours has helped me track down some unrelated memory leaks, I can't for the life of me figure out what's happening to the values I'm putting into my view! Oh, it's probably worth mentioning that I've got @synthesize for each of my outlets, and they're all hooked up in IB. Screenshot here.

    - by Meltemi
    I'm trying to do something I'd think would be fairly simple: Let a user input a dollar amount, store that amount in an NSNumber (NSDecimalNumber?), then display that amount formatted as currency again at some later time. My trouble is not so much with the setNumberStyle:NSNumberFormatterCurrencyStyle and displaying floats as currency. The trouble is more with how said numberFormatter works with this UITextField. I can find few examples. This thread from November and this one give me some ideas but leaves me with more questions. I am using the UIKeyboardTypeNumberPad keyboard and understand that I should probably show $0.00 (or whatever local currency format is) in the field upon display then as a user enters numerals to shift the decimal place along: Begin with display $0.00 Tap 2 key: display $0.02 Tap 5 key: display $0.25 Tap 4 key: display $2.54 Tap 3 key: display $25.43 Then [numberFormatter numberFromString:textField.text] should give me a value I can store in my NSNumber variable. Sadly I'm still struggling: Is this really the best/easiest way? If so then maybe someone can help me with the implementation? I feel UITextField may need a delegate responding to every keypress but not sure what, where and how to implement it?! Any sample code? I'd greatly appreciate it! I've searched high and low... Edit1: So I'm looking into NSFormatter's stringForObjectValue: and the closest thing I can find to what benzado recommends: UITextViewTextDidChangeNotification. Having really tough time finding sample code on either of them...so let me know if you know where to look?

  • Can't get Secondary UITableViewController to display inside a UITabBarController

    - by Paul Johnston
    I've programmatically created a UITabBarController that is loaded in my App Delegate like this: - (void)applicationDidFinishLaunching:(UIApplication *)application { tabBarController = [[UITabBarController alloc] init]; myTableViewController = [[MyTableViewController alloc] init]; UINavigationController *tableNavController = [[[UINavigationController alloc] initWithRootViewController:myTableViewController] autorelease]; myTableViewController.title = @"Tab 1"; [myTableViewController release]; mySecondTableViewController = [[MySecondTableViewController alloc] init]; UINavigationController *table2NavController = [[[UINavigationController alloc] initWithRootViewController:mySecondTableViewController] autorelease]; mySecondTableViewController.title = @"Tab 2"; [mySecondTableViewController release]; tabBarController.viewControllers = [NSArray arrayWithObjects:tableNavController, table2NavController, nil]; [window addSubview:tabBarController.view]; [window makeKeyAndVisible]; } Now the issue I have is that I can get into the views no problem, but when I try and click onto any item in the Table View, I can't get a secondary table view to appear in any tab. The tabs work absolutely fine, just the secondary views. I'm using the code below in my myTableViewController to run when selecting a specific row (the code reaches the HELP line, and crashes)... - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSUInteger row = [indexPath row]; // this gets the correct view controller from a list of controllers SecondaryViewController *svc = [self.controllers objectAtIndex:row]; /*** HELP NEEDED WITH THIS LINE ***/ [self.navigationController pushViewController:svc animated:YES]; } Simply put, I'm trying to switch views to the new view controller whilst keeping the tabs available and using the navigation to go back and forth (like in the iTunes App). Any help appreciated. Thanks

  • iPad app crashes when Youtube player clicked in UIWebView

    - by choonkeat
    I have a iPhone/iPad app (universal binary) with a regular UIWebView that displays webpages on the Internet. When the user presses on a Youtube embed, the iPhone app performs normally -- opening up the video player, when you close it, it returns to the app. However, on the iPad it crashes with Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIWindow addEventMonitor:]: unrecognized selector sent to instance 0x1219c0' #0 0x30c8e0a0 in __kill () #1 0x30c8e096 in kill () #2 0x30c8e088 in raise () #3 0x30ca2210 in abort () #4 0x32944a22 in __gnu_cxx::__verbose_terminate_handler () #5 0x335657ca in _objc_terminate () #6 0x32942df4 in __cxxabiv1::__terminate () #7 0x32942e48 in std::terminate () #8 0x32942f18 in __cxa_throw () #9 0x335646aa in objc_exception_throw () #10 0x32c9517a in -[NSObject doesNotRecognizeSelector:] () #11 0x32c94b00 in ___forwarding___ () #12 0x32c316d0 in __forwarding_prep_0___ () #13 0x32810492 in -[MPInactivityMonitor initForWindow:inactivityDuration:delegate:] () #14 0x32831dfe in -[MPFullScreenVideoViewController _createInactivityMonitor] () #15 0x328324bc in -[MPFullScreenVideoViewController showOverlayAnimated:] () #16 0x32833612 in -[MPAbstractFullScreenVideoViewController setControlsOverlayVisible:animate:] () #17 0x3281fca4 in -[UIMoviePlayerController setControlsOverlayVisible:disableAutohide:animate:] () #18 0x330bb444 in -[YTMovieView _switchToVideo:] () #19 0x330bb028 in -[YTMovieView willShowForVideo:inList:orVideoID:] () #20 0x04b8d142 in dyld_stub_time () #21 0x04b8b82e in dyld_stub_time () #22 0x32c2616c in -[NSObject performSelector:withObject:withObject:] () #23 0x3152716c in -[UIApplication sendAction:to:from:forEvent:] () #24 0x3152710c in -[UIApplication sendAction:toTarget:fromSender:forEvent:] () #25 0x315270de in -[UIControl sendAction:to:forEvent:] () #26 0x31526e30 in -[UIControl(Internal) _sendActionsForEvents:withEvent:] () #27 0x3152747e in -[UIControl touchesEnded:withEvent:] () #28 0x31525e54 in -[UIWindow _sendTouchesForEvent:] () #29 0x3152579c in -[UIWindow sendEvent:] () #30 0x315213be in -[UIApplication sendEvent:] () #31 0x31520d2a in _UIApplicationHandleEvent () #32 0x30d62b32 in PurpleEventCallback () #33 0x32c23d9c in CFRunLoopRunSpecific () #34 0x32c234e0 in CFRunLoopRunInMode () #35 0x30d620da in GSEventRunModal () #36 0x30d62186 in GSEventRun () #37 0x314d54c8 in -[UIApplication _run] () #38 0x314d39f2 in UIApplicationMain () (I don't even see my app in the stack trace (except for the top level main.m) In iPad Mobile Safari, on the same webpage, the video will play in-place on the webpage.

  • Opening a View with a Table without a NavigationController

    - by Ken
    Hiya, I'm pretty new to developing with Cocoa Touch/XCode and I came across a problem. I'm making a sort of RSS reader for a newssite and I have 5 views of tables navigated with 5 tabs in a TabBarController. If someone selects a newsitem I want another view to open showing the complete newsitem. My problem is that it won't work. This is my code: - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection(NSInteger)section{ return [[[self rssParser]rssItems]count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:@"rssItemCell"]; if(nil == cell){ cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"rssItemCell"]autorelease]; } cell.textLabel.text = [[[[self rssParser]rssItems]objectAtIndex:indexPath.row]title]; cell.detailTextLabel.text = [[[[self rssParser]rssItems]objectAtIndex:indexPath.row]description]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [[self appDelegate] setCurrentlySelectedBlogItem:[[[self rssParser]rssItems]objectAtIndex:indexPath.row]]; [self.appDelegate loadNewsDetails]; } And it calls this method in my delegate: -(void)loadNewsDetails{ [[self rootController]pushViewController:detailController animated:YES]; } Please tell me what I'm doing wrong. BTW I do not want to use a NavigationController, just the tabbar I'm using. Thanks in advance, Ken

  • Only first UIView added view addSubview shows correct orientation

    - by Brian Underwood
    I've got three ViewControllers set up to handle three views. The problem that I'm having is that in the simulator the orientation is LandscapeRight (which is what I want), and the first view shows up correctly in that landscape view, but when I move onto the second and third views, they show up rotated 90 degrees counter-clockwise with the upper-left corner of the view in the lower left corner of the phone's screen. I've been trying to debug this for a few days and the closest that I've gotten to a clue is tracing it the following way: The following is in my app delegate's applicationDidFinishLaunching: NSLog(@"1"); [window addSubview:welcomeController.view]; NSLog(@"2"); [window addSubview:goalController.view]; NSLog(@"3"); [window addSubview:planningController.view]; NSLog(@"4"); [window bringSubviewToFront:welcomeController.view]; NSLog(@"5"); Each of my ViewControllers implement something similar to the following (the only change being the controller's name switched out in the string passed to NSLog): - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations NSLog(@"called for WelcomeController"); return (interfaceOrientation == UIInterfaceOrientationLandscapeRight); } With that, I get the following output on the Console: a called for WelcomeController called for WelcomeController called for WelcomeController called for WelcomeController 2 called for GoalController 3 called for PlanningController 4 5 I find it interesting that shouldAutorotateToInterfaceOrientation is called 4 times for the first view that's added, while the other two only get called once. I expect that this is probably because it's got to do some setup at first (and I believe that the simulator starts off in portrait mode, so it's might be calling it while doing the rotation), but I find the correlation a bit suspicious. I've switched the order around so that the addSubview is called for the goalController first and the welcomeController second. In this case, it's the goalController which displays in the correct landscape orientation (it's normally the welcome controller). This would seem to eliminate my XIB files and the ViewControllers themselves. I'm not sure why the first view where addSubview is called is special. I also tried using insertSubview at index 0 with the same results.
