• UIDocumentInteractionController change title of presented view

  - by whatdoesitallmean

  I am using the UIDocumentInteractionController to display pdf files. My files are stored in the filesystem using encoded filenames that are not user-friendly. I do have access to a more friendly name for the file, but the file is not stored with this name (for uniqueness reasons). When I load the document into the UIDocumentInteractionController then the view displays the unfriendly 'real' filename in the titlebar. Is there any way to change the displayed title as presented by the UIDocumentInteractionController? Thanks.

• IOS How to make the view cover keyboard

  - by regrecall

  I encounter the a problem: I have a view controller like this. TO make tool bar up when the keyboard appear, I move the self.view to up. [self.view setFrame:CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y + keyboardFrame.size.height * (up ? -1 : 1), self.view.frame.size.width, self.view.frame.size.height)]; Now I want to click the left button in the tool bar, and appear the view that frame is same as the this keyboard. But where can I add this view? if add the subview to the self.view, it will move up with the self.view on the top of the keyboard, not cover. I'm a beginner about IOS, I have no idea about it, and have searched, but got nothing about this. another question, IF when the toolbar at the bottom, I aslo want to click the left button on it to show the view(the animation and frame both are the same as the keyboard), how can I do ? Can you help me? Thanks

• popViewControllerAnimated doesn't update info iPhone SDK

  - by WrightsCS

  When I try to pop a view controller, it doesnt update info for the previous view. Example: I have a cell that displays text in a label in View1. When you click on the cell it goes to View2 (for example) When I choose an option in View2, popViewControllerAnimated is used to go back to View1, however, I want the label to now be updated with the new option in View1. My dilemma is that when I pop View2, the label in View1 does not update. Any ideas? I've tried adding a [view1 reloadData]; before the view pops, but no luck. //VIEW1 the cell that displays the label. ringLabel = [[UILabel alloc] initWithFrame: CGRectMake(25, 12.7f, 250, 20)]; ringLabel.adjustsFontSizeToFitWidth = YES; ringLabel.textColor = [UIColor blackColor]; ringLabel.font = [UIFont systemFontOfSize:17.0]; ringLabel.backgroundColor = [UIColor clearColor]; ringLabel.textAlignment = UITextAlignmentLeft; ringLabel.tag = 0; ringLabel.text = [plistDict objectForKey:@"MYOPTION"]; [ringLabel setEnabled:YES]; [cell addSubview: ringLabel]; [ringLabel release]; //VIEW2 when cell clicked CustomProfileViewController *cpvc = [CustomProfileViewController alloc]; cpvc.ringtone = [ringList objectAtIndex:indexPath.row]; [cpvc.tblCustomTable reloadData]; [self.navigationController popViewControllerAnimated:YES];

• what's the right way to cause a subview to redraw when the device orientation changes?

  - by RobertL

  I have a view controller with a view and one subview. When the device orientation changes the view auto-redraws but the subview doesn't. If I explicitly do [subview setNeedsDisplay] it redraws but I don't have a logical place to put that call in my code. And, since I don't have to explicitly tell the view to redraw, it seems counter-intuitive to tell the subview to redraw. Is there a way to make the subview auto-redraw when the view redraws?

• UINavigationController from scratch?

  - by Moshe

  I have a view based app that works well. (In other words, I'm not going to start over with a Navigation-Based App template.) It's an immersive app of sorts and I'm trying to add a Table View that loads in a new view when a button is pressed. The loading the nib part works, but I can't seem to be able to add a navigation controller to the new view. I want to see a navigation bar on top with a done button and an edit button. Also, I want to the Table View entries to be empty. I added a new file like so: File-> New File -> UINavigationController subclass. I checked the UITableViewController Subclass and With XIB for user interface. All I see when the view is pulled up is a blank Table View. I am able to customize things in the view controller. What can I do to make the table show a navigation bar and be editable? I need some direction here please. EDIT: I'm working with the latest Public SDK. (XCode 3.2.2)

• [self removeFromSuperview] not doing dealloc

  - by jonydep

  i have this in the superview: mySubView = [[MySubView alloc] init]; [self addSubview:mySubView]; [mySubView release]; then at some point later, in the sub view, this: [self removeFromSuperview]; when i debug it, i notice that the dealloc for the subview is never called, even though i'm fairly sure the reference count should be 0. any ideas why this might be? thanks.

• Print UITableView that has content off screen?

  - by Daniel

  Hi I have an iOS app that has the ability to print a UITableView. However, only th part of the tableview that is shown is printed. Is there a way to print the whole tableview, even if it has not been drawn yet? Here is the code I am using to print: UIGraphicsBeginImageContext(self.mainTableView.contentSize); [self.mainTableView.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); UIPrintInteractionController *printer = [UIPrintInteractionController sharedPrintController]; printer.printingItem = viewImage; UIPrintInfo *info = [UIPrintInfo printInfo]; printer.printInfo = info; UIPrintInteractionCompletionHandler completionHandler = ^(UIPrintInteractionController *pic, BOOL completed, NSError *error) { if (!completed && error) NSLog(@"FAILED! due to error in domain %@ with error code %u: %@", error.domain, error.code, [error localizedDescription]); }; UIButton * printButton = (UIButton *)sender; if(UIUserInterfaceIdiomPad == [[UIDevice currentDevice] userInterfaceIdiom]){ [printer presentFromRect:printButton.frame inView:self.view animated:YES completionHandler:completionHandler]; } else { [printer presentAnimated:YES completionHandler:completionHandler]; }

• How do I show a custom UIImagePicker within a view?

  - by cory ginsberg

  I'm making an app that involves a 'mirror.' Basically, the view should show the UIImagePickerControllerCameraDeviceFront with a custom border around it that I would create. I have looked around the web for days and I can only find a way of putting a subview on the camera view, I want it to be the opposite way. I have seen this happen before, but I have no idea as how to do it as it appears that UIImagePickerController must be a superview and can't be a subview. Please help me anyway you can and thank you in advanced.

• Changing UIViews during UIInterfaceOrientation on iPad

  - by FreeAppl3

  I am trying to change views on rotation because my views have to be significantly different from portrait to landscape. Now the code I am using works once then the app freezes when trying to rotate back. Either direction does not make a difference. For example: If I am in Landscape and rotate to portrait everything works great until I rotate back to landscape then it freezes and does absolutely nothing. Here is the code I am using to achieve this In my "viewDidLoad" method [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didRotate:) name:UIDeviceOrientationDidChangeNotification object:nil]; Then I call this for the rotation: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { // Return YES for supported orientations return YES; } - (void)didRotate:(NSNotification *)notification { UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation]; if ((orientation == UIDeviceOrientationLandscapeLeft) || (orientation == UIDeviceOrientationLandscapeLeft)) { // present the other viewController, it's only viewable in landscape [self.view addSubview:landScapeView]; } if ((orientation == UIDeviceOrientationLandscapeRight) || (orientation == UIDeviceOrientationLandscapeRight)) { // present the other viewController, it's only viewable in landscape [self.view addSubview:landScapeView]; } else if ((orientation == UIDeviceOrientationPortrait || (orientation == UIDeviceOrientationPortrait)) { // get rid of the landscape controller [self.view addSubview:portrait]; } else if ((orientation == UIDeviceOrientationPortraitUpsideDown || (orientation == UIDeviceOrientationPortraitUpsideDown)) { // get rid of the landscape controller [self.view addSubview:portrait]; } }

Thanks alot for your help.

• remove 2 subviews in one go.

  - by Pavan

  hi, I am trying to remove two viewcontrollers (that have been added on top of each other) with one method. I have made the views in interfacebuilder. they all have their own .h and .m files to go with it. Scenario I am in: I have a main menu which has the view2 header file imported. In a method I add the second view on top of the superview like so view2ViewController * view2 = [[view2ViewController alloc] initWithNibName:@"view2ViewController" bundle:nil]; [self.view addSubview:view2.view]; then in view 2 I have added the view 3 header file so i can add view 3 as a subview ontop of view2. i have another method which is connected again to interface builder to a UIButton so upon button press a method gets called in view2 which adds view 3 on top in exactly the same way like so: view3ViewController * view3 = [[view3ViewController alloc] initWithNibName:@"view3ViewController" bundle:nil]; [self.view addSubview:view3.view]; What im trying to solve: I have a button in view 3 which should remove view 3.... and then it should also remove view 2 aswell so the main screen is visible. How can this be achieved? What I have so far: [self.view removeFromSuperview]; This however only removes View 3... but leaves view 2 in place. What needs to be modified so that i can remove view 2 as well?? Any help is appreciated.

• How to tell whether on sub-view's is above another sub-view?

  - by Horace Ho

  Assume there are 3 sub-views (A, B, C) in a view. After a few rounds of random bringSubviewToFront and sendSubviewToBack on A, B, or C , how can I tell whether one sub-view (e.g. A) is on top of another sub-view (e.g. C)? Whether they overlap each other is not required information. Thanks!

• iPhone loading view from nib only works once

  - by The Swissdude

  Hi Forum I'm trying to add a «loader-view» to my app which shows a spinner while doing stuff. This works fine the first time, but it doesn't work a second time. here's what I do: I have a viewController for the spinner (spinnerViewController) and a nib-file which I made in IB (spinner.xib). I load the nib in the viewDidLoad-event: spinnerView = [[spinnerViewController alloc] initWithNibName:@"spinner" bundle:nil]; [spinnerView retain]; spinnerView is declared in the .h-file (spinnerViewController *spinnerView;) next, I show the spinner-view: [self.view addSubview:spinnerView.view]; [self.view bringSubviewToFront:spinnerView.view]; which works fine... And now the trouble starts. No matter what I do, I can't show the spinner view again. I tried just hiding it (self.view sendSubViewToBack: spinnerView.view) which works for hiding, but when I try to bring it to the front again (self.view bringSubViewToFront: spinnerView.view) it doesn't work. I also tried removing the spinner-view and add it again with no success (within the spinnerViewController: [self.view removeFromSuperview] and to show it again [self.view addSubview... ) Any ideas what I'm doing wrong??? ;) Thanks for the help!

• Creating a button on a View from a second View

  - by BigJoke

  Hi, I have this app I'm working on, which on a second view asks (textfield) the name for a button to be created on first view. After specifying the name and pressing OK button, the first view pops up (as demanded) but there's no new button, although created indeed. Can I use the following code in a second view method, to "refresh" the first view before presenting itself. What's wrong with this code? Any other approach? Thank you. -(void)initWithView:(View1Controller *)aSuperview { theSuperview = aSuperview; } - (IBAction)itemNameButton { ... CGRect rectang; rectang = CGRectMake(0, 0, 320, 460);// just in case [theSuperview.view setNeedsDisplayInRect:rectang]; ... }

• why i change the alpha value of UIImageView but no effect?

  - by chancy

  I am working on a reader app. when you read one magazine, it will display first five pages and download the rest pages one by one. there is a scrollview to view the thumbnail image of pages. At the beginning, if the page needs downloading, the corresponding thumbnail view's alpha value is set to 0.5. when the page is downloaded, i will update the thumbnail view's value to 1.0. I use one operation to download the page, and when one is downloaded i use delegate to set thumbnail view's alpha. But when i update thumbnail view's alpha value, it still the same as the beginning. it seems the alpha has no effect. I wonder is there anything wrong with my code? some snippets are as follows: In the PageViewController.m - (void)downloadPages { DownloadOperation *op = [[DownloadOperation alloc] initWithMagazine:magazine]; op.delegate = self; [[(AppDelegate *)[[UIApplication sharedApplication] delegate] sharedOperationQueue] addOperation:op]; } - (void)downloadOperation:(DownloadOperation *)operation finishedAtIndex:(NSUInteger)index { if (thumbScrollView){ [thumbScrollView viewWithTag:THUMBVIEW_OFFSET+index].alpha = 1.0; } } In DownloadOperation.m - (void)main { // ... NSUInteger index = 0; for (Page *page in mMagazine.pages) { if (/*page doesn't exist*/){ // download the page; if ([delegate respondsToSelector:@selector(downloadOperation:finishedAtIndex:)]) { [delegate downloadOperation:self finishedAtIndex:index]; } } index++; } }

• UITableView cell selection disabled and UITableViewHeader Enabled

  - by andyPaul

  I am adding a my header view to self.tableView.tableHeaderView=headerView; This tableView has 10 cells. I want to disable the cell Selection but, headerView touch events must be enabled. To achieve this I added the following code: self.tableView.userInteractionDisabled=YES; self.headerView.userInteractionDisabled=NO; self.headerView.exclusiveTouch=YES; Where I am wrong? Basic idea of implementation is , If headerView is enabled then cell selection is disabled and vice-versa.

• Collision detection on sub views contained in 2 separate parent UIViews?

  - by Chris

  Hi All, I originally setup some conditions using CGRectIntersectsRect for some collision detection which worked fine. In the greater scale of things I only need part of the view to be detected. So originally within the ViewController it was comparing 2 UIviews. Now what I need to do is collision detection of subViews within 2 different UIViews that are contained in a view in which the view controller does the logic. My script is no longer working as I suspect CGRectIntersectsRect only compares frames within the same view? I'll keep digging to confirm this. Any ways around this? Is it possible for example to get the x and y pos of the sub view in relation to the main view that's performing the logic?

• Completely Removing Views from memory

  - by cannyboy

  I have a view which is set up to train 'voiceprints' of words (this voiceprint code is not mine), and another view which has a slideshow which is controlled by the voiceprint. Unfortunately, these views conflict because they are still in memory. As far as I know, viewDidUnload and dealloc are only called in low-memory situations, and dealloc should not be called directly, so how do I completely remove a view. These views are within uinavigationcontrollers by the way.
