  • NSPredicate 'OR' filtering based on an NSArray of keys

    - by So Over It
    Consider the following NSArray: NSArray *dataSet = [[NSArray alloc] initWithObjects: [NSDictionary dictionaryWithObjectsAndKeys:@"abc", @"key1", @"def", @"key2", @"hij", @"key3", nil], [NSDictionary dictionaryWithObjectsAndKeys:@"klm", @"key1", @"nop", @"key2", nil], [NSDictionary dictionaryWithObjectsAndKeys:@"qrs", @"key2", @"tuv", @"key3", nil], [NSDictionary dictionaryWithObjectsAndKeys:@"wxy", @"key3", nil], nil]; I am able to filter this array to find dictionary objects that contain the key key1 // Filter our dataSet to only contain dictionary objects with a key of 'key1' NSString *key = @"key1"; NSPredicate *key1Predicate = [NSPredicate predicateWithFormat:@"%@ IN self.@allKeys", key]; NSArray *filteretSet1 = [dataSet filteredArrayUsingPredicate:key1Predicate]; NSLog(@"filteretSet1: %@",filteretSet1); Which appropriately returns: filteretSet1: ( { key1 = abc; key2 = def; key3 = hij; }, { key1 = klm; key2 = nop; } ) Now, I am wanting to filter the dataSet for dictionary objects containing ANY of the keys in an NSArray. For example, using the array: NSArray *keySet = [NSArray arrayWithObjects:@"key1", @"key3", nil]; I want to create a predicate that returns and array of any dictionary objects that contain either 'key1' or 'key3' (ie. in this example all dictionary objects would be returned except for the third object - as it does not contain either 'key1' or 'key3'). Any ideas on how I would achieve this? Would I have to use a compound predicate?

  • How to do something when AVQueuePlayer finishes the last playeritem

    - by user1634529
    I've got an AVQueuePlayer which I'm creating from an array of 4 AVPlayerItems, and it all plays fine. I want to do something when the last item in the queue finishes playing, I've looked a load of answers on here and this is the one that looks most promising for what I want: The best way to execute code AFTER a sound has finished playing In my button handler i have this code: static const NSString *ItemStatusContext; [thePlayerItemA addObserver:self forKeyPath:@"status" options:0 context:&ItemStatusContext]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playerItemDidReachEnd) name:AVPlayerItemDidPlayToEndTimeNotification object:thePlayerItemA]; theQueuePlayer = [AVQueuePlayer playerWithPlayerItem:thePlayerItemA]; [theQueuePlayer play]; and then I have a function to handle playerItemDidReachEnd: - (void)playerItemDidReachEnd:(NSNotification *)notification { // Do stuff here NSLog(@"IT REACHED THE END"); } But when I run this I get an Internal Inconsistency Exception: An -observeValueForKeyPath:ofObject:change:context: message was received but not handled. Key path: status Observed object: <AVPlayerItem: 0x735a130, asset = <AVURLAsset: 0x73559c0, URL = file://localhost/Users/mike/Library/Application%20Support/iPhone%20Simulator/5.0/Applications/A0DBEC13-2DA6-4887-B29D-B43A78E173B8/Phonics%2001.app/yes.mp3>> Change: { kind = 1; } What am I doing wrong?

    I am having a very frustrating error. I have tested for an app upgrade by first installing the previous version (1.0.1) and then running version (1.0.2). Everything worked fine. I submitted the app and then I am getting issues people are getting crashes when they upgrade. I tried doing the same thing, which is installing the 1.0.1 and then install the binary on the app store, then it crashed.

  • What is the most efficient way to use Core Data?

    - by Eric
    I'm developing an iPad application using Core Data, and was hoping someone could clarify something about Core Data. Right now, I populate my table by making a fetch request for all of my data in viewDidLoad. I'd rather make individual fetch requests in my tableView:cellForRowAtIndexPath:. Can anyone tell me which is more efficient, and why? In other words, is it much less efficient to make lots of small requests as opposed to one big request?

  • Adding UIView on top of all views dynamically during runtime?

    - by Easwaramoorthy Kanagaraj
    Team, I am trying to bring a menu in top of all visible views during runtime. This menu should be easily addable and removable dynamically in certain conditions. To do this, I have tried adding a button view to the UIWindow as a subview during runtime. UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; [button addTarget:self action:nil forControlEvents:UIControlEventTouchDown]; [button setTitle:@"Show View" forState:UIControlStateNormal]; button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0); [window addSubview:button]; [window makeKeyAndVisible]; [window bringSubviewToFront:button]; But it doesnt worked. Also I have tried to place this button in the root view controller, but no luck again. Edit - Note: This code is not from a UIViewController. I am trying to build a library this will be in that library code. Use case be like you could post NSNotification to enable and disable this menu dynamically during runtime. Please suggest. Thanks !

  • collapsing a UITableView

    - by Sage Washabaugh
    Hey everyone I made a UITableView in my app and when a cell is touched it expands the problem I am having is it does not collapse no matter what I have tried, I'm sure its something easy i just cant figure it out the only time it does collapse is when it another cell is tapped. Here is my code: -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { selectedCellIndexPath = indexPath; [tableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationNone]; if (selectedCellIndexPath) { selected = YES; } } -(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { if(selectedCellIndexPath != nil && [selectedCellIndexPath compare:indexPath] == NSOrderedSame) return 150; return 44; }

  • Drawing animation

    - by HHHH
    I'm creating a simple app where when the user presses a button, a series of lines will be drawn on the screen and the user will be able to see these lines drawn in real time (almost like an animation). My code looks something like this (has been simplified): UIGraphicsBeginImageContext(CGSizeMake(300,300)); CGContextRef context = UIGraphicsGetCurrentContext(); for (int i = 0; i < 100; i++ ) { CGContextMoveToPoint(context, i, i); CGContextAddLineToPoint(context, i+20, i+20); CGContextSetStrokeColorWithColor(context, [[UIColor blackColor] CGColor]); CGContextStrokePath(context); } UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); My problem is that: 1) As soon as the user presses the button, the UIThread blocks until the drawing is done. 2) I can't get the lines to be drawn on the screen one at a time - I've tried setting the UIImage directly inside the loop and also tried setting a layer content inside the loop. How do I get around these problems?

  • ViewController Navigating

    - by Kobe.o4
    I have 4 ViewControllers, startViewController as the initial View Controller. This contains my intro. After its finish, it will [self presentViewController:vc animated:YES completion:NULL]; into my menuViewController. startViewController ------> menuViewController ------> C1ViewController \ \ ------> ImportantViewController In my menuViewController are buttons for the two ViewController like the above illustration. Also I presented them in the View with this: [self presentViewController:vc animated:YES completion:NULL]; I return tomenuViewController with this [self dismissModalViewControllerAnimated:YES]; What I wanted is to make the ImportantViewController to be the like the parent view or the mainVIew even if I go to other Views. What I need is when ImportantViewController is presented when I go to either C1ViewController or menuViewController it wont be deallocated, or its content there will still be retained. Is it possible? And How? I don't know much about what parent and child view controllers for so I dont know what to implement in my problem. Thank you. BTW, Im using Storyboard.

  • iDevice for Dummies: Can a device be assigned multiple provisions (Personal/Enterprise)?

    - by Alex
    Hi guys, Is it possible to assign multiple provisions to an iDevice? To be honest, I'm not sure if I'm using the correct terminology, but basically, I'm developing an iPad app for a company and I've only been testing it in the simulator because I don't have a registration to the developer program and they haven't setup their enterprise registration yet either. And I'm sure you all know how limited the simulator is... I don't really care about the $99 it costs to join, but what I'm worried about is having my iDevices locked permanently to my personal registration and unable to switch back and forth to the enterprise registration. I'd appreciate it if someone can explain to me how the registrations work. And keep in mind, I'm a dummy. :) Thanks in advance!

  • Redrawing content of UIWebView

    - by btate
    I have a bunch of webviews with static html content that I'm putting in a scroll view as pages. That works fine, but having 20 something full screen subviews of the scroll view is causing some lag. I solved that by only placing 5 at a time in there. The current view, and the two next and two previous. The problem now is that any web view that is not a subview of the scroll view is not drawing correctly based on the device orientation. The frame of the webview is printing out correct, but the actual content is drawing in portrait mode. So there is essentially a strip of blank space to the right of the content. How do I go about re rendering the content without reloading the page? Here's the relevant code: - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation) fromInterfaceOrientation{ [self resizeSubViews]; } - (void) setupWebViews{ if(_webViews == nil) _webViews = [[NSMutableArray alloc] init]; // This is where the navigation would come into play as far as loading up available web views [_webViews removeAllObjects]; // for loop here to create web views for (int i = 0; i < 20; i++) { //CDCWebViewController *webView = [[[MyInternalWebView alloc] initWithFrame:_webViewWrapper.frame] retain]; MyInternalWebView *page = [[[MyInternalWebView alloc] init] retain]; [page loadRequest:[NSURLRequest requestWithURL:_url]]; [page setCdcIWVdelegate:self]; [page setTestIndex:i]; [page setPageIndex:i]; [_webViews addObject:page]; [self loadScrollViewWithPage:i]; } [self clearUnusedWebViews:_pageControl.currentPage]; } - (void) setupWebViewWrapper{ // a page is the width of the scroll view _webViewWrapper.pagingEnabled = YES; _pageControl = [[[UIPageControl alloc] init] retain]; _webViewWrapper.showsHorizontalScrollIndicator = NO; _webViewWrapper.showsVerticalScrollIndicator = NO; _webViewWrapper.scrollsToTop = NO; _webViewWrapper.delegate = self; _pageControl.numberOfPages = [_webViews count]; _pageControl.currentPage = 0; } - (void) resizeSubViews{ // The frame is set in IB _webViewWrapper.contentSize = CGSizeMake(_webViewWrapper.frame.size.width * [_webViews count], _webViewWrapper.frame.size.height); // Move the content offset. _webViewWrapper.contentOffset = CGPointMake(_webViewWrapper.frame.size.width * _pageControl.currentPage, _webViewWrapper.contentOffset.y); for (MyInternalWebView *subview in _webViewWrapper.subviews) { // Reset the frame height and width here? CGRect frame = _webViewWrapper.frame; frame.origin.x = frame.size.width * subview.pageIndex; frame.origin.y = 0; [subview setFrame:frame]; } } //***************************************************** //* //* ScrollView Functions //* //***************************************************** - (void)loadScrollViewWithPage:(int)page { // Make sure we're not out of bounds if (page < 0) return; if (page >= [_webViews count]) return; MyInternalWebView *webView = [_webViews objectAtIndex:page]; // Add the preloaded webview to the scrollview if it's not there already if (nil == [webView superview]) { CGRect frame = _webViewWrapper.frame; //NSLog(@"width = %f", frame.size.width); frame.origin.x = frame.size.width * page; frame.origin.y = 0; //NSLog(@"setting frame for page %d %@", page, NSStringFromCGRect(frame)); [webView setFrame:frame]; [_webViewWrapper addSubview:[_webViews objectAtIndex:page]]; // Now that the new one is loaded, clear what doesn't need to be here [self clearUnusedWebViews:page]; } } - (void) clearUnusedWebViews: (NSInteger) page{ for (int i = 0; i < [_webViews count]; i++) { if ((page - i) <= 2 && i - page <= 2) { continue; } [[_webViews objectAtIndex:i] removeFromSuperview]; } } - (void)scrollViewDidScroll:(UIScrollView *)sender { // Switch the indicator when more than 50% of the previous/next page is visible CGFloat pageWidth = _webViewWrapper.frame.size.width; NSInteger page = floor((_webViewWrapper.contentOffset.x - pageWidth / 2) / pageWidth) + 1; _pageControl.currentPage = page; // load the visible page and the page on either side of it (to avoid flashes when the user starts scrolling) [self loadScrollViewWithPage:page - 2]; [self loadScrollViewWithPage:page - 1]; [self loadScrollViewWithPage:page]; [self loadScrollViewWithPage:page + 1]; [self loadScrollViewWithPage:page + 2]; }

  • Odd Segue Behaviour - Not Firing

    - by Zak
    So I've noticed some very weird behaviour from my program. Here's a simplified code snippet and then I'll explain what occurs when built and ran. -(void)viewDidLoad { [super viewDidLoad]; ... if (self.sampleBool) { [self performSegueWithIdentifier:@"mySegue" sender:self]; } else { // do stuff } } ... -(IBAction)myMethod:(UITapGestureRecognizer*)sender { ... [self performSegueWithIdentifier:@"mySegue" sender:self]; } The segue triggers via the UITapGestureRecognizer fine - so I know the segue is linked correctly. However, when self.sampleBool is true and performSegueWithIdentifier is called within viewDidLoad, the segue does not fire. Anyone have any guesses? Any help or advice is appreciated. Thanks

  • 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++; } }

  • Frame sizing of tableview within nested child controllers/subviews

    - by jwoww
    I'm a bit confused by the proper frame sizing of a table view to fit within my screen. Here's my setup of view controllers within view controllers: UITabBarController UINavigationController as one of the tab bar viewcontrollers; title bar hidden ViewController - a container view controller because I need the option to place some controls beneath the UITableView, sometimes (but not in the current scenario) UITableViewController Now, my question is what the proper frame dimensions of the UITableview should be. Here's what I've got in the ViewController viewDidLoad method. I used subtracted 49.0 (the size of the tab bar) from 480.0. However, this leaves a black bar at the bottom. 20.0 appears to do it (coincidentally?) the size of the status bar, but I don't understand why that would be. Wouldn't the true pixel dimensions of the tableview be 480-49? // MessageTableViewController is my subclass of UITableViewController MessagesTableViewController *vcMessagesTable = [[MessagesTableViewController alloc] init]; CGRect tableViewFrame = CGRectMake(0, 0, 320.0, 480.0 - 49.0); [[vcMessagesTable view] setFrame:tableViewFrame]; self.tableViewController = vcMessagesTable; [self addChildViewController:vcMessagesTable]; [[self view] addSubview:vcMessagesTable.view]; Here's how it looks:

  • what is the required code method of making a sticker app?

    - by zeropt7
    I am new to photo apps, recently I am interested in making a sticker app like those can be seen in the appstore, I know I would need to use uiimagepickercontroller, uiscrollview and uigesturerecognizer. However I wonder which code method should I use for the app to load multiple stickers? Should it be called programmatically? Is that I would need to use the if-statement, say if one sticker is loaded, the app will auto generate a new sticker on top of it?

  • Navigation Bar color doesn't change back? iOS7

    - by TKP
    I have several tableviews with navigation controller. The navigation bar is white for all the views except the last one, which is red. I have [[[self navigationController] navigationBar] setTintColor:[UIColor redColor]; in the viewDidLoad of the last tableview and [[[self navigationController] navigationBar] setTintColor:[UIColor whiteColor]; in the viewDidLoad of other table views. It works fine until I get to the last view and the color of the navigation bar changes to red. When I go back to the previous views, all the previous views' navigation bar has changed to red. Where should I put those codes so the color will remain unchanged? Thanks,

  • 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.

  • Different icons and title for same iPad application

    - by trapo
    I'm developing an iPad application that will be distributed "in-house" ie only inside enterprise. They asked me if i can produce 2 different releases of the same application to be installed on the same iPad. The first one will communicate with a production server while the second will use a sandbox server and will be used by user to learn the system. Server url will be changed in app settings.
