  • How to pushviewcontroller to a viewcontroller stored in a tabbaritem?

    - by Jann
    First of all I know this is a long question. REST ASSURED I have tried to figure it out on my own (see: StackOverflow #2609318). This is driving me BATTY! After trying and failing to implement my own EDIT feature in the standard moreNavigationController, I have decided to re-implement my own MORE feature. I did the following: Add a HOME view controller which I init with: initWithRootViewController Add 3 other default tabs with: ResortsListViewController *resortsListViewController; resortsListViewController = [[ResortsListViewController alloc] initWithNibName:@"ResortsListView" bundle:nil]; resortsListViewController.title = [categoriesDictionary objectForKey:@"category_name"]; resortsListViewController.tabBarItem.image = [UIImage imageNamed:@"whatever.png"]; resortsListViewController.navigationItem.title=@"whatever title"; localNavigationController = [[UINavigationController alloc] initWithRootViewController:resortsListViewController]; localNavigationController.navigationBar.barStyle = UIBarStyleBlack; [localControllersArray addObject:localNavigationController]; [localNavigationController release]; [resortsListViewController release]; Those work when i add them to the tabbar. (ie: click on them and it goes to the view controller) Then I add my own MORE view controller to the tabbar: MoreViewController *moreViewController; moreViewController = [[MoreViewController alloc] initWithNibName:@"MoreView" bundle:nil]; moreViewController.title = @"More"; moreViewController.tabBarItem.image = [UIImage imageNamed:@"more.png"]; moreViewController.navigationItem.title=@"More Categories"; localNavigationController = [[UINavigationController alloc] initWithRootViewController:moreViewController]; localNavigationController.navigationBar.barStyle = UIBarStyleBlack; [localControllersArray addObject:localNavigationController]; [localNavigationController release]; [moreViewController release]; Then tabBarController.viewControllers = localControllersArray; tabBarController.moreNavigationController.navigationBar.barStyle = UIBarStyleBlack; tabBarController.customizableViewControllers = [NSArray arrayWithObjects:nil]; tabBarController.delegate = self; That creates the necessary linkages. Okay, so far all is well. I get a HOME tab, 3 category tabs and a customized MORE tab -- which all work. in the MORE tab view controller I implement a simple table view that displays all the other tabs I have in rows. SINCE I want to be able to switch them in and out of the tabbar I created them JUST like i did the resortslistviewcontroller above (ie: as view controllers in an array). When I pull them out to display the title in the tableview (so the user can go to that "view") i simply do the following: // [myGizmoClass CategoryArray] holds the array of view controller tab bar items that are NOT shown on the main screen. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { ... etc... UIViewController *Uivc = [[myGizmoClass plusCategoryArray] objectAtIndex:indexPath.row]; cell.textLabel.text = [Uivc title]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } THIS is where it falls through: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { MyGizmoClass *myGizmoClass= [MyGizmoClass sharedManager]; UIViewController *tbi = [[myGizmoClass plusCategoryArray] objectAtIndex:indexPath.row]; NSLog(@"%@\n",[[tbi navigationItem ]title]); [self.navigationController pushViewController:tbi animated:YES]; } This is the error i get ("ATMs" is the title for the clicked tableview cell so i know the Uivc title is pulling the correct title and therefore the correct "objectatindex": 2010-04-09 11:25:48.222 MouseAddict[47485:207] ATMs 2010-04-09 11:25:48.222 MouseAddict[47485:207] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Pushing a navigation controller is not supported' BIG QUESTION: How do i make the associated VIEW of the UIViewController *tbi show and get pushed into view? I am GUESSING that the UIViewController is the correct class for this tbl .. i am not sure. BUT i just wanna get the view so i can push it onto the stack. Can someone plz help?

  • 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]; }

  • UIView rotation, modal view lanscape and portrait, parent fails to render

    - by Ben
    Hi everyone, I've hit a bit of a roadblock with something that I hope that someone in here can help me out with. I'll describe the 'state of play' first, and then what the issue is, so here goes; I have a series of view controllers that are chained together with a Navigation Controller (this works just fine), All of these view controllers support portrait mode only (by design), In one of the view controllers (the 'end' one actually) the user can click a table cell to pop up a modal view controller (using presentModalViewController(...) of course) This modal view controller supports portrait and landscape modes (and this works), When the user clicks the 'Done' button on this modal view controller we pop and pass control back to the parent view controller, however; If the user is in portrait mode when they click 'Done' then the parent displays itself just fine, If the user is in landscape mode when they click 'Done' then the parent displays a totally white, blank screen (that covers the whole screen). It is as if the controller does not know how to render in landscape and just doesn't bother. I'd like to be able to have this parent view render in portrait no matter what the orientation of the phone is when the user clicks the 'Done' button. Various forum posts suggest using the UIDevice method 'setOrientation' (but this is undocumented and will get our app rejected apparently). Another suggestion was to set the 'statusBarOrientation' to portrait in the 'viewWillAppear' method but that had no effect. So I am a bit stuck! Has any encountered anything like this before? If need be I can provide code, if that will help anyone diagnose the problem for me. Thanks in advance! Cheers, Ben

  • OpenGL view in an iPad splitview

    - by dc
    I'm attempting to add an OpenGL view (such as the one given in Apple's sample code) as the detail view of an iPad's splitview but am running into issues. I've taken the sample code from the base OpenGL project and attempted to add it as a subview of my DetailViewController - ie EAGLView *glview = [[EAGLView alloc] initWithFrame:CGRectMake(0,0,100,100)] but when I add it to the main view and call startAnimating on it, nothing at all happens. Any solutions to this? I have never worked with OpenGL before so perhaps I'm doing this all wrong.

  • Must I call super when I implement -scrollViewDidScroll: of UIScrollViewDelegate in an UITableView?

    - by mystify
    I made a custom UITableView subclass and implemented this: - (void)scrollViewDidScroll:(UIScrollView *)scrollView { // scrolled... } Now, what I think is that UITableView may also love to get this message for some obvious reasons. However, when I don't forward that to super, for some reason, everything still works fine. Must I forward that guy to super? I mean...it's a delegate method implementation, but as far as I'm aware of, this would still override anything implemented in UITableView, or not? Edit: I see...the delegate could be anyone. Never mind about this. BUT: What I have such a thing in a superclass, and make a subclass. How would I even know that the superclass does implement that method and I must forward it to super?

  • How to unit test asynchronous APIs?

    - by Ben Clayton
    Hi all. I have installed Google Toolbox for Mac (http://code.google.com/p/google-toolbox-for-mac/) into Xcode and followed the instructions to set up unit testing found here (http://code.google.com/p/google-toolbox-for-mac/wiki/iPhoneUnitTesting). It all works great, and I can test my synchronous methods on all my objects absolutely fine. However, most of the complex APIs I actually want to test return results asynchronously via calling a method on a delegate - for example a call to a file download and update system will return immediately and then run a -fileDownloadDidComplete: method when the file finishes downloading. How would I test this as a unit test? It seems like I'd want to the testDownload function, or at least the test framework to 'wait' for fileDownloadDidComplete: method to run. Any ideas much appreciated!

  • Error while creating in app purchase in itunes connect

    - by MW
    I'm having trouble while creating an In App Purchase in iTunes Connect. I have created a test user and am able to see the form for creating the in app purchase. However, when pressing 'Save' I get the following error message: "There was an error saving changes. Please try again later. If the problem persists, please contact us." This error has persisted for about 24 hours now. Have you encountered this problem, and do you know any way to get around it? Edit 2009-11-10: I just received a response from my email to Apple. It stated that they will start looking into it, and expect to have a solution within three business days. As soon as I hear something new, I'll post it here.

  • UIImagePickerController Save to Disk then Load to UIImageView

    - by Harley Gagrow
    Hi, I have a UIImagePickerController that saves the image to disk as a png. When I try to load the PNG and set a UIImageView's imageView.image to the file, it is not displaying. Here is my code: (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage]; NSData *imageData = UIImagePNGRepresentation(image); // Create a file name for the image NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setTimeStyle:NSDateFormatterShortStyle]; [dateFormatter setDateStyle:NSDateFormatterShortStyle]; NSString *imageName = [NSString stringWithFormat:@"photo-%@.png", [dateFormatter stringFromDate:[NSDate date]]]; [dateFormatter release]; // Find the path to the documents directory NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; // Now we get the full path to the file NSString *fullPathToFile = [documentsDirectory stringByAppendingPathComponent:imageName]; // Write out the data. [imageData writeToFile:fullPathToFile atomically:NO]; // Set the managedObject's imageLocation attribute and save the managed object context [self.managedObject setValue:fullPathToFile forKey:@"imageLocation"]; NSError *error = nil; [[self.managedObject managedObjectContext] save:&error]; [self dismissModalViewControllerAnimated:YES]; } Then here is how I try to load it: self.imageView.backgroundColor = [UIColor lightGrayColor]; self.imageView.frame = CGRectMake(10, 10, 72, 72); if ([self.managedObject valueForKey:@"imageLocation"] != nil) { NSLog(@"Trying to load the imageView with: %@", [self.managedObject valueForKey:@"imageLocation"]); UIImage *image = [[UIImage alloc] initWithContentsOfFile:[self.managedObject valueForKey:@"imageLocation"]]; self.imageView.image = image; } else { self.imageView.image = [UIImage imageNamed:@"no_picture_taken.png"]; } I get the message that it's trying to load the imageView in the debugger, but the image is never displayed in the imageView. Can anyone tell me what I've got wrong here? Thanks a bunch.

  • NSFetchedResultsController Crashes When Navigating from One UITableViewController to Another

    - by wgpubs
    In my core data model I have a Person entity that has a "to many" relationship a Course entity (I also have an inverse "to one" relationship from Course to Person). Now I have a subclassed UITableViewController that uses a NSFetchedResultsController to display Person objects which works fine. I have this set up so that when you click on a Person it publishes another subclassed UITableViewController that uses a NSFetchedController as well to display the Courses associated to the person. PROBLEM: I get this exception whenever I click on the Person and attempt to display the Course UITableViewController ... "Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'keypath name not found in entity <NSSQLEntity Course id=2>'" Any ideas on how to resolve or troubleshoot? The code between the two ViewControllers is almost identical except for the NSFetchedResultsController being configured for "Person" entities in one and "Course" entities in another

  • CGContextDrawPDFPage doesn't seem to persist in CGContext

  • Moving a point along a vector

    - by Chris
    Hello- I have a point defined by x,y and a vector defined by heading, speed. I am attempting to move the point x,y along this vector, at a distance of 'speed'. Below is the code I am currently using: self.x += self.speed * cos(self.heading); self.y += self.speed * sin(self.heading); Heading can be any angle in a full circle - 0 to 2p (0-360 degrees). The problem is the above code: Only moves along the x or y axis when angle is 0-270 for example, when the avatar is facing the top-right corner (45 degrees relative), it moves straight up. Does not move at all when angle is 270-360 heading, speed, X and Y are all doubles, and heading is reported by the user touching a direction-pad in the lower corner. I know the heading is correct because the avatar rotates to the correct direction, it is just the actual movement I am having problems with. Thanks for any help - Chris

  • Groupted table view cells not loading.

    - by Tejaswi Yerukalapudi
    Hi, I'm working on creating a grouped table view. The data is being loaded alright, but in the grouped view there are a lot of white empty spaces. They get populated after I scroll up and down a few times. Help? Here's my getCellForRowIndexAtPath method: static NSString *Id= @"CustomDiagChargeID"; CustomCellDiagCharges *cell = (CustomCellDiagCharges *)[tableView dequeueReusableCellWithIdentifier:Id]; if(cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CustomCellDiagCharges" owner:self options:nil]; for (id oneObject in nib) { if([oneObject isKindOfClass:[CustomCellDiagCharges class]]) cell = (CustomCellDiagCharges *) oneObject; } } NSUInteger row = [indexPath row]; DiagDetails *rowData = [preferences getDiagElementAt:indexPath.section row:row]; cell.code.text = rowData.ICD9Code; cell.desc.text = rowData.ICD9Desc; return cell; Thanks, Teja.
