  • Xcode - some variables don't show

    - by Mike
    This picture shows a debugging session. "lista" is a NSMutableArray containing, in this case, two elements: 0 and 1. Each element's content is seen on the debugging window as {(unichar *)Xcode_CFStringSummary($VAR, $ID)}:s but if I double click on any element, its value shows on a pop up window. Why is the values don't showing directly? How to force Xcode to show the values instead of this stupid and useless "{(unichar *)Xcode_CFStringSummary($VAR, $ID)}:s" ? thanks for any help.

  • iPhone: CATiledLayer/UIScrollView wont scroll after zooming and only zooms to anchor point

    - by Brodie4598
    Here is the problem... I am using CA Tiled Layer to display a large jpg. The view loads okay, and when I go to scroll around, it works fine. However, as soon as I zoom in or out once, it scrolls to the top left (to the anchor point) and will not scroll at all. The zooming works fine, but I just cannot scroll. Here is my code: #import <QuartzCore/QuartzCore.h> #import "PracticeViewController.h" @implementation practiceViewController //@synthesize image; - (void)viewDidLoad { NSString *path = [[NSBundle mainBundle] pathForResource:@"H-5" ofType:@"jpg"]; NSData *data = [NSData dataWithContentsOfFile:path]; image = [UIImage imageWithData:data]; CGRect pageRect = CGRectMake(0, 0, image.size.width, image.size.height); CATiledLayer *tiledLayer = [CATiledLayer layer]; tiledLayer.anchorPoint = CGPointMake(0.0f, 1.0f); tiledLayer.delegate = self; tiledLayer.tileSize = CGSizeMake(1000, 1000); tiledLayer.levelsOfDetail = 6; tiledLayer.levelsOfDetailBias = 0; tiledLayer.bounds = pageRect; tiledLayer.transform = CATransform3DMakeScale(1.0f, -1.0f, 0.3f); myContentView = [[UIView alloc] initWithFrame:self.view.bounds]; [myContentView.layer addSublayer:tiledLayer]; UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:self.view.bounds]; scrollView.delegate = self; scrollView.contentSize = pageRect.size; scrollView.minimumZoomScale = .2; scrollView.maximumZoomScale = 1; [scrollView addSubview:myContentView]; [self.view addSubview:scrollView]; } - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return myContentView; } - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx { NSString *path = [[NSBundle mainBundle] pathForResource:@"H-5" ofType:@"jpg"]; NSData *data = [NSData dataWithContentsOfFile:path]; image = [UIImage imageWithData:data]; CGRect imageRect = CGRectMake (0.0, 0.0, image.size.width, image.size.height); CGContextDrawImage (ctx, imageRect, [image CGImage]); } @end

  • UITextView text disappear

    - by user153412
    Hi, i create an uitextview dynamically then i write my text into it. Sometime, when i create the uitextview, the cursor disappear and i see no text in it. If i run the application again, i can see the text inside the textview that i've created before. I've tried to set the cursor position to zero or scroll the text to the top but it doesn't work... Any suggestion? Here is a screen capture. You can see the gray uitextview, the keyboard (the textview is the firstresponder) but no cursor or text. http://yfrog.com/hqschermata20100325a11213p PS: i'm sorry for my bad english.

  • Intercept UITableView scroll touches

    - by Jonesy
    Is it possible to control when the UITableView scrolls in my own code. I am trying to get behaviour where a vertical swipe scrolls and a horizontal swipe gets passed through to my code (of which there are many example) BUT I want a DIAGONAL swipe to do nothing, i.e the UITableView should not even begin scrolling. I tried catching it in here - (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView but the scrollView.contentOffset.x is always 0 so I cannot detect a horizontal movement. I also tried subclassing UITableView and implementing - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event - (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event etc.. but the UITableView (and I guess it's parent UIScrollView) start to scroll before the touches are notified? To re-iterate, I want the UITableView scrolling to be locked if a diagonal swipe is made, but to scroll vertically normally. (This behaviour can be seen in Tweetie(Twitter) for the iPhone) Thanks for any help!

  • jQuery UI Datepicker and Google Chrome not working

    - by zA
    Hi, I'm having some problems with jQueryUI Datepicker and Google Chrome. My datepicker is working as expected with IE8, Firefox and Safari. The problem is when clicking the datepicker connected textbox in Chrome. It gives me a crash page, "Oops, an error occurred...". On my page there's textbox with a datepicker. The datepicker is language dependent and it loads the correct language settings dynamically. The datepicker should also display the month and year dropdowns. The code is as follows $(function() {$.datepicker.setDefaults($.extend({ changeMonth: true, changeYear: true }, $.datepicker.regional['']));$('#<%= TextBoxBirthDate.ClientID %').datepicker($.datepicker.regional[$('#LabelRegionalSettings').val()]);}); If I only extend the datepicker with one option, i.e. changeYear, it works in Chrome. But if I add another option, i.e. changeMonth, the 'crash' in Chrome occurs. Is my code incorrect? If so, how do I fix it? Any help is greatly appreciated!

  • Why is Dispatcher.Invoke not triggering UI update?

    - by Brandon
    I am trying to reuse a UserControl and also borrow some logic that keeps track of progress. I'll try and simplify things. MyWindow.xaml includes a MyUserControl. MyUserControl has its own progress indicator (Formatting in progress..., Copying files..., etc.) and I'd like to mirror this progress somewhere in the MyWindow form. But, the user control has some logic I don't quite understand. I've read and read but I still don't understand the Dispatcher. Here's a summary of the logic in the user control that updates the progress. this.Dispatcher.Invoke(DispatcherPriority.Input, (Action)(() => { DAProgressIndicator = InfiniteProgress.AddNewInstanceToControl(StatusGrid, new SolidColorBrush(new Color() { A = 170, R = 128, G = 128, B = 128 }), string.Empty); DAProgressIndicator.Message = MediaCardAdminRes.ActivatingCard; ActivateInProgress = true; })); I thought I'd be smart and add an event to MyUserControl that would be called in the ActivateInProgress property set logic. public bool ActivateInProgress { get { return _activateInProgress; } set { _activateInProgress = value; if (ActivateInProgressHandler != null) { ActivateInProgressHandler(value); } } } I'm setting the ActivateInProgressHandler within the MyWindow constructor to the following method that sets the view model property that is used for the window's own progress indicator. private void SetActivation(bool activateInProgress) { viewModel.ActivationInProgress = activateInProgress; } However, the window's progress indicator never changes. So, I'm convinced that the Dispatcher.Invoke is doing something that I don't understand. If I put a message box inside the SetActivation method, the thread blocks and the window's progress indicator is updated. I understand basic threads but this whole Dispatcher thing is new to me. What am I missing?

  • using jquery draggable can you create a helper based on the dragged item?

    - by user169867
    I wish to create a custom helper based on the element being dragged. I'm dragging documents and I'd like the document's number to be part of the custom helper. I know how to create a helper during init like this: helper: function() { return $("<div class='fax16'></div>"); } But what I really want to do is maybe in response to the start event get access to the element being dragged and use some of its properties to set the helper. Something like: start: function(event, ui) { var docID = //somehow access the dragged element ui.helper = $("<div class='save16'>" + docID + "</div>"); //Set drag Helper } Can this be done?

  • Core Data iPhone how often should I call [managedObjectContext save:&error] when doing 50k record in

    - by jamone
    I will be doing an occiasional import from XML into core data. I have around 50k entities that will be added. My question is how often should I call [managedObjectContext save:&error]. For every new entity added, or every x entities, or just at the end of the 50k import? I currently am calling it for each entity and tried only doing it for around every 10k and import speed went up drastically but after the first 30k it would crash with: *** Terminating app due to uncaught exception 'NSGenericException', reason: '*** Collection <NSCFSet: 0x13e760> was mutated while being enumerated.' Before I spend too much time trying to diagnose what is going on there I figured I'd check if its ok to not call save on every entity? Is the # of entities before calling save limited by the amount of memory those entities are using?

  • Can dummy objects be simulated on iphone?

    - by Mike
    I come from 3D animation and one of the basic things all 3D software have is the ability to create dummy objects. Dummy objects can be used to groups objects that can be rotated, moved or scaled together around a specific anchor point. This is the idea of what I am asking. Obviously we can have fake dummies by using a view and put other views as subviews, but this has problems as the view receives clicks and sometimes you don't want it to do so. You cannot change the anchorpoint of a view too. So, the dummies as I ask have, at least, these properties: adjustable anchor point it is not clickable it is totally invisible (cannot be rendered). any scale, rotation and translation of a dummy are propagated to the grouped objects considering the dummy's anchor point. it is totally animatable. Can this be simulated on iPhone? Is there any object that can be created to simulate this? thanks.

  • iPhone - move above buttons

    - by Mike
    I have a video at 320x240 on the middle of the screen area. Around this video, several buttons that will call different actions. When the MPMoviePlayerController is fired and the movie starts playing the buttons are behind the video and I cannot click them. I see them but they are not clickable. I think the video window is covering the whole area. How can I solve that?

  • How to compare two times in milliseconds precision?

    - by Marcos Issler
    I have a subtitle text file that works with standart srt format 00:00:00,000 Hour, minutes, seconds, milliseconds. I want to create a timer to update the subtitle screen and check the current time to know what subtitle show on screen. Which is the best to use? NSTimeInterval, NSDate? I think the best is to convert all to times to milliseconds number and compare. But NSTimeInterval works with seconds, not milliseconds. Some clue? Marcos

  • iphone - compiler conditionals

    - by Mike
    Two questions: this code #ifdef __IPHONE_3_0 // iPhone 3.0 specific stuff #else // iPhone 2.2 specific stuff #endif compiles specific codes for specific versions of the iPhone. How could this be transformed to compile for a range of devices? For example: if iphone version < 3.1 or if version = 3.2, and so one... 2) where do I get a list of all conditionals allowed by Xcode? thanks for any help.

  • Collection <NSCFSet: 0x1b0b30> was mutated while being enumerated. How to determine which set?

    - by jamone
    I'm doing a bunch of core data inserts and after 20k or so inserts with saves every 1-2k I get this error: Terminating app due to uncaught exception 'NSGenericException', reason: '*** Collection <NSCFSet: 0x1b0b30> was mutated while being enumerated.' I'm trying to figure out which NSSet is causing this. I've done a search and the only NSSets in my code are the autogenerated ones that handle the Core Data relationships. I'm using NSXMLParser and for each element found creating a new entity (if a matching one doesn't already exist). So I will create a state entity and then populate all the city entities and then do a save. This means that a state's NSSet *cities is getting added to but I don't see why you can't do that.

  • Azure Membership UI

    - by Andres
    Using AspProviders (TableStorageMembershipProvider etc) from Microsoft WCF Azure Samples. It is WCF Service Web Role, and in Azure Storage Explorer I can see Membership, Roles and Session tables appearing nicely when I try to connect. But is there any exisiting code to manage Membership and Roles? Some ASPX pages I guess, something like this for plain old ASP.NET, but more modern and Azure-tested hopefully? Thanks, Andres

    - by carloe
    Not sure if I can explain this correctly, but I am trying to execute a method device orientation animation finishes. Right now I have [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didRotate:) name:UIDeviceOrientationDidChangeNotification object:nil];, but that triggers instantly. Is there a way to have it call didRotate after the view rotation animation is completed? Thanks!
