  • Mobile Safari Youtube opened via javascript

    - by Squeegy
    We have a youtube player embedded in a plage in Mobile Safari and it works great. But we need to be able to launch the youtube player by a means other than user tapping the video itself, for various reasons. So I am trying to figure out what event to trigger in javascript to make it happen with no luck. None of the following appear to work. var vid = document.getElementById('vid'); vid.click(); vid.onclick(); vid.ontouchend(); vid.ontouchstart(); vid.focus(); I tried to find an event handler added to the embedded object with this snippet, but didn't find anything. for (var key in vid) { if (typeof vid[key] == 'function') console.log(key +': '+ vid[key]); } Is this just so wrapped up in a custom plugin there is no way?

  • Copy NSArray and replace text items with bool values

    - by Frank Martin
    I utilize a (nested) plist to populate UITableViews where users can select entries at the deepest levels and set a checkmark (or not). I want to save these selections in a same structured list where at the deepest level the NSArray contains bool values instead the text strings that are displayed in the UITableView. So how can i build from a hierarchy like the following: Root - Item 0 (Dictionary) - Group (Dictionary) - Items (NSArray) - Item 0: @"Please check me" (String) a hierarchy like this? Root - Item 0 (Dictionary) - Group (Dictionary) - Items (NSArray) - Item 0: 0 (NSNumber) // NSNumber for bool values I'm trying to create a deep mutable copy and replace the items at the deepest levels but have somehow the feeling that this can be done easier. Thanks for any help with this in advance. Frank

  • UIActivityView and blocking

    - by Rob Bonner
    Hello, I have a section of code that uploads an image: [activity startAnimating]; [self uploadImage:img Session_id:appDelegate.sessionID PlaceID:place.placeID Comment:comment.text]; [activity stopAnimating]; I am sure that activity is wired up correctly to a UIActivityViewIndicator, but it never shows. Inside the uploadImage function, I open a connection to the server and start the upload. Does anyone have an example or possible explanation as to why the activity view would not display?

  • Properly maintain sorted state of Array/Set

    - by Jeff
    I'm trying to get data out of my MOC and then create some new objects based on those objects, and put it all back together, while keeping my sort state. The securities come out of the MOC in proper order. And everything seems to be fine until I do the assignment to the game at the bottom from setWithArray. The documentation says that setWithArray removed the duplicate objects, if there are any. I'm wonder if that's messing up my data, but I don't see a good alternative. The data is ultimately being pulled out into a UITableView. When I add items to the game manually, then they stay sorted, so I don't think the breaking of the sort is beyond the scope of what I've included here. NSError *error; NSArray *allTheSecurities = [managedObjectContext executeFetchRequest:request error:&error]; if (allTheSecurities == nil) { // Handle the error. } [request release]; /**/ NSLog( @"Enumerate..." ); NSEnumerator *enumerator = [allTheSecurities objectEnumerator]; id anObject; NSMutableArray *portfolioStocks = [[NSMutableArray alloc] init]; while (anObject = [enumerator nextObject]) { NSLog( @"Iteration... %@", [anObject name] ); NSLog( @"Build a stock..." ); PortfolioStocks *this_stock = (PortfolioStocks *)[NSEntityDescription insertNewObjectForEntityForName:@"PortfolioStocks" inManagedObjectContext:context]; NSLog( @"Set a value..." ); [this_stock setSecurity:(Security *)anObject]; [this_stock setQuantity:[NSNumber numberWithInt:0]]; NSLog( @"Add to portfolioStocks..." ); [portfolioStocks addObject:this_stock]; } //Sorted properly up to here! NSLog( @"Add to portfolio..." ); [game setPortfolio:[NSSet setWithArray:portfolioStocks]]; // <-- This is where it's not sorted anymore.

  • iOS: click counter for row in tableview

    - by roger.arliner21
    I am developing and tableView in which in each row I have to display the click counter and row number.Each cell must have an initial click counter value of 0 when application is initialized. Then increment the click counter value within a cell whenever a user clicks on the cell. I have take 26 fixed rows. I have taken tableData.plist file as in the attached image. I am initializing the self.dataArray with the plist . Now I want to do implementation in the didSelectRowAtIndexPath delegate method,if any row is tapped that row's click counter should increment. - (void)viewDidLoad { [super viewDidLoad]; NSString *path = [[NSBundle mainBundle] pathForResource:@"tableData" ofType:@"plist"]; self.dataArray = [NSMutableArray arrayWithContentsOfFile:path];//array initialized with plist } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [self.dataArray count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *kCustomCellID = @"MyCellID"; UILabel *label1 = [[UILabel alloc] initWithFrame:CGRectMake(160.0f, 2.0f, 30.0f, 20.0f)]; UILabel *label2 = [[UILabel alloc] initWithFrame:CGRectMake(160.0f, 24.0f, 30.0f, 30.0f)]; label2.textColor = [UIColor grayColor]; UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:kCustomCellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:kCustomCellID] autorelease]; cell.selectionStyle = UITableViewCellSelectionStyleNone; } if([self.dataArray count]>indexPath.row) { label1.text = [[self.dataArray objectAtIndex:indexPath.row] objectForKey:@"Lable1"]; label2.text =[[self.dataArray objectAtIndex:indexPath.row] objectForKey:@"Lable2"]; } else { label1.text = @""; label2.text =@""; } [cell.contentView addSubview:label1]; [cell.contentView addSubview:label2]; [label1 release]; [label2 release]; return cell; } #pragma mark - #pragma mark Table view delegate - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //implementation for row counter incrementer. }

  • How to have a UISwipeGestureRecognizer AND UIPanGestureRecognizer work on the same view

    - by Shizam
    How would you setup the gesture recognizers so that you could have a UISwipeGestureRecognizer and a UIPanGestureRecognizer work at the same time? Such that if you touch and move quickly (quick swipe) it detects the gesture as a swipe but if you touch then move (short delay between touch & move) it detects it as a pan? I've tried various permutations of requireGestureRecognizerToFail and that didn't help exactly, it made it so that if the SwipeGesture was left then my pan gesture would work up, down and right but any movement left was detected by the swipe gesture.

  • Using Kal calendar without doing the initialization (and so on) in the AppDelegate

    - by testing
    I'm using the Kal calendar. For the code shown below I'm referring to the Holiday example. In this example the allocation and initialization of Kal is done in the applicationDidFinishLaunching in the AppDelegate. The UITableViewDelegate protocol (e.g. didSelectRowAtIndexPath) is also positioned in the AppDelegate class. The AppDelegate: #import "HolidayAppDelegate.h" #import "HolidaySqliteDataSource.h" #import "HolidaysDetailViewController.h" ## Heading ###import "Kal.h" @implementation HolidayAppDelegate @synthesize window; - (void)applicationDidFinishLaunching:(UIApplication *)application { kal = [[KalViewController alloc] init]; kal.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Today" style:UIBarButtonItemStyleBordered target:self action:@selector(showAndSelectToday)] autorelease]; kal.delegate = self; dataSource = [[HolidaySqliteDataSource alloc] init]; kal.dataSource = dataSource; // Setup the navigation stack and display it. navController = [[UINavigationController alloc] initWithRootViewController:kal]; [window addSubview:navController.view]; [window makeKeyAndVisible]; } // Action handler for the navigation bar's right bar button item. - (void)showAndSelectToday { [kal showAndSelectDate:[NSDate date]]; } #pragma mark UITableViewDelegate protocol conformance // Display a details screen for the selected holiday/row. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { Holiday *holiday = [dataSource holidayAtIndexPath:indexPath]; HolidaysDetailViewController *vc = [[[HolidaysDetailViewController alloc] initWithHoliday:holiday] autorelease]; [navController pushViewController:vc animated:YES]; } #pragma mark - - (void)dealloc { [kal release]; [dataSource release]; [window release]; [navController release]; [super dealloc]; } @end I don't want to put this into the AppDelegate, because there could be some overlapping code with other views. It should be a separate "component" which I can call and put on the stack. In my navigation based project I have a main view, the RootViewController. From there I want to push the Kal view on the stack. Currently I'm pushing an additional ViewController on the stack. In the viewWillAppear method from this ViewController I do the things shown in the code above. The following problems appear: Navigation back has to be done two times (one for the Kal calendar, one for my created view) Navigation to my main view is not possible anymore In the moment I don't know where to put this code. So the question is where to put the methods for allocation/initialization as well as the methods for the UITableViewDelegate protocol.

  • UIImageView Fade-In Dissapears

    - by Winder
    I have this code which should create a splash image with either no animation or a fade in, then call code to dismiss the image out after a delay. The SplashViewAnimationNone works fine and creates the full screen image, but the Fade code fades the image in but then immediately disappears. - (void)startSplash { [[[[UIApplication sharedApplication] windows] objectAtIndex:0] addSubview:self]; splashImage = [[UIImageView alloc] initWithImage:self.image]; if (self.animationIn == SplashViewAnimationNone) { [self addSubview:splashImage]; } else if (self.animationIn == SplashViewAnimationFade) { [self addSubview:splashImage]; CABasicAnimation *animSplash = [CABasicAnimation animationWithKeyPath:@"opacity"]; animSplash.duration = self.animationDelay; animSplash.removedOnCompletion = NO; animSplash.fillMode = kCAFillModeForwards; animSplash.fromValue = [NSNumber numberWithFloat:0.0]; animSplash.toValue = [NSNumber numberWithFloat:1.0]; animSplash.delegate = self; [self.layer addAnimation:animSplash forKey:@"animateOpacity"]; } // Dismiss after delay. [self performSelector:@selector(dismissSplash) withObject:self afterDelay:self.delay]; }

  • My xcode mapview wont work when combined with webview

    - by user1715702
    I have a small problem with my mapview. When combining the mapview code with the code for webview, the app does not zoom in on my position correctly (just gives me a world overview where i´m supposed to be somewhere in California - wish I was). And it doesn´t show the pin that I have placed on a specific location. These things works perfectly fine, as long as the code does not contain anything concerning webview. Below you´ll find the code. If someone can help me to solve this, I would be som thankful!

  • Strategy to keep track of stored files in the documents directory?

    - by mystify
    In my app, the user can save his input to disk. This is done with NSKeyedArchiver. Currently I simply name my files with a timestamp. But of course, the user may want to load one of them back in to keep on editing them. What would be the most reliable / safe strategy to keep track of those files? I need to present the user a list of those files, so that he can choose one to open. Currently I think of making an archived NSMutableArray which simply stores the file names, but I feel that this strategy is not really good. We all know when we save files sometimes something goes wrong, and this seems very likely to get currupted easily, or not? How would you do it?

  • MPMoviePlayerController playback problem

    - by Fahri
    Hello all, I'm having trouble with playing audio stream using MPMoviePlayerController in the background. On the foreground it's playing the audio just fine, but when the application goes to the background, sound disappears and the time keeps going. I have initialized the AVAudioSession with AVAudioSessionCategoryPlayback and have put the required background modes to audio in info.plist file. Also I have set player.useApplicationAudioSession = YES;. What could be the possible problem here? Thanks in advance :)

  • Confused about UIView frame property

    - by slowfungus
    I'm building a prototype iPad app that draws diagrams. I have the following view hierarchy: UIView UIScrollView DiagramView : UIView TabBar NavigationBar And a UIViewController subclass holding all that together. Before drawing the diagram the first time I calculate the dimensions of the diagram, and set the DiagramView frame to that size, and the content size of the scrollview as well. -(void)recalculateBounds { [renderer diagram:diagram shouldDraw:NO]; SQXRect diagramRect = SQXMakeRect(0.0,0.0,[diagram bounds].size.width,[diagram bounds].size.height); self.frame = diagramRect; [(UIScrollView*)[self superview] setContentSize:diagramRect.size]; } I should disclose that the frame is being set to about 1500 x 3500 which i know is ridiculous. I just want to focus on some other parts of the app before I get into optimizing the render code. This works beautifully, except that the rect being passed to drawRect is not the size that I set, and my drawing is getting clipped at the bottom. Its close the size i set, but bigger in width, and shorter in height. Also of note, is the fact that if I force the frame to be much bigger than what I know the diagram needs, then the drawRect:rect is big enough, and no clipping occurs. Of course this has me wondering if the frame size needs to take into account some other screen real estate like the toolbars but my reading of the docs tells me the frame is in superview coordinates, which would be the scrollview so I reckon I need to worry about such things. Any idea what is causing this discrepancy?

  • Not sure how to use ccTouchesBegan to do what I want it to do.

    - by thyrgle
    So when I see ccTouchesBegan (or touchesBegan for that fact of the matter) I see something like this usually: - (void)ccTouchesBegan:(NSSet*)touches withEvent:(UIEvent*)event { UITouch* touch = [touches anyObject]; } But, what I am not getting is how do you just detect if one object has been touched? For example how would I check if a specific CCSprite I declared has been touched? Sorry if this is a newbish question but, I just don't understand and if you need more clarification just ask how I can clarify myself more.

  • How to add a leftBarButtonItem to ABPeoplePickerNavigationController?

  • NSTimer as a timeout mechanism

    - by alexantd
    I'm pretty sure this is really simple, and I'm just missing something obvious. I have an app that needs to download data from a web service for display in a UITableView, and I want to display a UIAlertView if the operation takes more than X seconds to complete. So this is what I've got (simplified for brevity): MyViewController.h @interface MyViewController : UIViewController <UITableViewDelegate, UITableViewDataSource> { NSTimer *timer; } @property (nonatomic, retain) NSTimer *timer; MyViewController.m @implementation MyViewController @synthesize timer; - (void)viewDidLoad { timer = [NSTimer scheduledTimerWithTimeInterval:20 target:self selector:@selector(initializationTimedOut:) userInfo:nil repeats:NO]; [self doSomethingThatTakesALongTime]; [timer invalidate]; } - (void)doSomethingThatTakesALongTime { sleep(30); // for testing only // web service calls etc. go here } - (void)initializationTimedOut:(NSTimer *)theTimer { // show the alert view } My problem is that I'm expecting the [self doSomethingThatTakesALongTime] call to block while the timer keeps counting, and I'm thinking that if it finishes before the timer is done counting down, it will return control of the thread to viewDidLoad where [timer invalidate] will proceed to cancel the timer. Obviously my understanding of how timers/threads work is flawed here because the way the code is written, the timer never goes off. However, if I remove the [timer invalidate], it does.

  • Save UIView's representation to file.

    - by fish potato
    What is the easiest way to save UIView's representation to file? My solution is, UIGraphicsBeginImageContext(someView.frame.size); [someView drawRect:someView.frame]; UIImage *image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); NSString* pathToCreate = @"sample.png"; NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(image)]; [imageData writeToFile:pathToCreate atomically:YES]; but it seems tricky, and I think there must be more efficient way to do this.

  • Why can't I save changes to application settings with NSUserDefaults?

    I am using the following code to save values from a settings view that takes values from a UITextField and stores them with NSUserDefaults.

What am I doing wrong here? - (IBAction)save { NSLog(@"save"); NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; if (self.usernameTextField.text != nil) { NSLog(@"username: %@", self.usernameTextField.text); [defaults setObject:kTwitterUsernameKey forKey:self.usernameTextField.text]; } if (self.passwordTextField.text != nil) { NSLog(@"password: %@", self.passwordTextField.text); [defaults setObject:kTwitterPasswordKey forKey:self.passwordTextField.text]; } [defaults synchronize]; [self dismissModalViewControllerAnimated:TRUE]; }

  • iOS - Passing variable to view controller

    - by gj15987
    I have a view with a view controller and when I show this view on screen, I want to be able to pass variables to it from the calling class, so that I can set the values of labels etc. First, I just tried creating a property for one of the labels, and calling that from the calling class. For example: SetTeamsViewController *vc = [[SetTeamsViewController alloc] init]; vc.myLabel.text = self.teamCount; [self presentModalViewController:vc animated:YES]; [vc release]; However, this didn't work. So I tried creating a convenience initializer. SetTeamsViewController *vc = [[SetTeamsViewController alloc] initWithTeamCount:self.teamCount]; And then in the SetTeamsViewController I had - (id)initWithTeamCount:(int)teamCount { self = [super initWithNibName:nil bundle:nil]; if (self) { // Custom initialization self.teamCountLabel.text = [NSString stringWithFormat:@"%d",teamCount]; } return self; } However, this didn't work either. It's just loading whatever value I've given the label in the nib file. I've littered the code with NSLog()s and it is passing the correct variable values around, it's just not setting the label. Any help would be greatly appreciated. EDIT: I've just tried setting an instance variable in my designated initializer, and then setting the label in viewDidLoad and that works! Is this the best way to do this? Also, when dismissing this modal view controller, I update the text of a button in the view of the calling ViewController too. However, if I press this button again (to show the modal view again) whilst the other view is animating on screen, the button temporarily has it's original value again (from the nib). Does anyone know why this is?
