  • Camera Filters in ios7

    - by Muhannad Dasoqie
    How I can use the camera filters that already exist in iOS7? If i used this code: UIImagePickerController *picker= [[UIImagePickerController alloc]init]; picker.delegate = self; picker.allowsEditing = YES; picker.sourceType = UIImagePickerControllerSourceTypeCamera; [self presentModalViewController:picker animated:YES]; the camera will open, and I can capture a photo but without using the filters. my question is: can I use the exist filters in camera view in iOS7?

  • C# Login Dialog Implementation

    - by arc1880
    I have implemented a LoginAccess class that prompts the user to enter their active directory username and password. Then I save the login data as an encrypted file. Every subsequent start of the application, the LoginAccess class will read the encrypted file and check against the active directory to see if the login information is still valid. If it is not, then it will prompt the user again. I have made it so that the reading of the encrypted file and displaying of the login dialog is done on a separate thread. A delegate is fired when the login process is complete. The issue that I'm having is that I have a class that is used in multiple places. This class contains the call to the LoginAccess object. Every time I instantiate a new object there are multiple calls to the LoginAccess object and I get multiple dialogs appearing when it tries to prompt for a username and password. Any suggestions on how to have only one dialog appear would be greatly appreciated.

  • Downloading PKPass in an iOS custom app from my server

    - by taurus
    I've setup a server which returns a PKPass. If I copy the URL to the browser, a pass is shown (both in my Mac and in my iPhone). The code I'm using to download the pass is the following one: NSData *data = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:kAPIPass]]; if (nil != data) { PKPass *pass = [[PKPass alloc] initWithData:data error:nil]; PKAddPassesViewController *pkvc = [[PKAddPassesViewController alloc] initWithPass:pass]; pkvc.delegate = self; [self presentViewController:pkvc animated:YES completion:^{ // Do any cleanup here } ]; } Anyway, when I run this code I have the following error: * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Only support RGBA or the White color space, this method is a hack.' I don't know what is the bug... The pass seems ok when I download it with Safari and even the code seems ok (there are just 3 simple rows...) Someone experienced with Passkit could help me? EDIT: the weird thing is that the exact same code is working in a fresh new project

  • jQyery bind on ajax load() event

    - by Andrei C
    Hi guys. I have a page which display multiple blocks with results details. Inside each block I have some tags with thichbox jQuery plugin attached( class="thichbox"). http://jquery.com/demo/thickbox/ here is an example of one kind of ampersant tag: <a class="thickbox" title="Please Sign In" href="userloginredir.php?height=220&width=350&deal=3"> Problem comes when I added a jQuery pagination to the page because of to many results displaying on the page. The div component with the results inside is updated through ajax load() event. Below is the pagination script. $(document).ready(function(){ //References var pages = $("#menu_deals li"); var loading = $("#loading_deals"); var content = $("#content_deals"); //show loading bar function showLoading(){ loading .css({visibility:"visible"}) .css({opacity:"1"}) .css({display:"block"}) ; } //hide loading bar function hideLoading(){ loading.fadeTo(1000, 0); }; //Manage click events pages.live('click',function(){ //show the loading bar showLoading(); //Highlight current page number pages.css({'background-color' : ''}); $(this).css({'background-color' : 'yellow'}); //Load content var pageNum = this.id; var targetUrl = "ajax_search_results.php?page=" + pageNum + "&" + $("#dealsForm").serialize() + " #content_d"; content.load(targetUrl, hideLoading); }); //default - 1st page $("#1").css({'background-color' : 'yellow'}); var targetUrl = "ajax_search_results.php?page=1&" + $("#dealsForm").serialize() + " #content_d"; showLoading(); content.load(targetUrl, hideLoading); }); When I added pagination(code above), the thickbox events are not recognized anymore and instead of poping out a window with the login form inside it opens the results in new page (is acting like clicking on a normal link) From my jQuery knowledge this means that the components are not defined in the DOM because the content is updated after document ready triggered. I'm trying to bind the load event with something like this: content.bind('load',???); But I don't know how to pass the load params, targetUrl and the callback function hideLoading, when binding the load event. Please help me out in this matter, already took me more time than possible allowed. Thank you!

  • WPF: Disable ListBox, but enable scrolling

    - by Matt Briggs
    Been banging my head against this all morning. Basically, I have a listbox, and I want to keep people from changing the selection during a long running process, but allow them to still scroll. Solution: All the answers were good, I went with swallowing mouse events since that was the most straight forward. I wired PreviewMouseDown and PreviewMouseUp to a single event, which checked my backgroundWorker.IsBusy, and if it was set the IsHandled property on the event args to true.

  • UICollectionViewController nested in a normal UIViewController

    - by patrickS
    I have added a UICollectionView into a normal ViewController (MainViewController), and than created a UICollectionViewController Subclass (CollectionViewController) in the ViewController and connected the UICollectionView outlet with the CollectionViewController object _collectionViewController = [[CollectionViewController alloc] initWithCollectionViewLayout:_collectionView.collectionViewLayout]; _collectionView.dataSource = _collectionViewController; _collectionView.delegate = _collectionViewController; In the CollectionViewController I have setup an simple NSArray object and I show this one. This works as expected. But If I try to access the collectionview from the CollectionViewController via self.collectionview I am not able to access this one. I dont know what I have to do, to also connect the collectionview. I have build a sample ios-app it is available at: https://github.com/patricks/uicollectionview-problem The method - (void)outputSelectedCell in the UICollectionViewController always shows, that there is nothing selected… I hope you understand the problem.

I have called (gdb) po UIImagePNGRepresentation(image) right after setImage and stuffed the output into a file. The file is a perfect png. Has anyone experienced the same? Has anyone found a solution for it? Thanks in advance Max

  • UIViewController dismissModalViewControllerAnimated: causes main window to disappear

    - by Jim
    I want to present a modal mail dialogue like so in the iPad app: MFMailComposeViewController* picker = [[MFMailComposeViewController alloc] init]; picker.mailComposeDelegate = self; [picker setSubject:title]; [picker setMessageBody:[NSString stringWithFormat:[self emailBody], title, [link absoluteString]] isHTML:YES]; [self.viewController presentModalViewController:picker animated:YES]; The following delegate is called when the user sends/cancels: - (void) mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error { [self.viewController dismissModalViewControllerAnimated:YES]; } This works great in portrait mode. In landscape mode the right hand pane of the UISplitViewController completely disappears.

  • Setting a "dependency property" in code

    - by Matt B
    I'm on a roll today... I have the following code delaring a dependency property inside a class called ActionScreen: #region Dependency Properties & Methods public string DescriptionHeader { get { return (string)GetValue(DescriptionHeaderProperty); } set { SetValue(DescriptionHeaderProperty, value); } } // Using a DependencyProperty as the backing store for DescriptionHeader. This enables animation, styling, binding, etc... public static readonly DependencyProperty DescriptionHeaderProperty = DependencyProperty.Register("DescriptionHeader", typeof(string), typeof(ActionScreen), new UIPropertyMetadata("xxx")); #endregion I bind to this property in my Xaml as so: <GridViewColumn DisplayMemberBinding="{Binding Description}" Header="{Binding DescriptionHeader}" Width="350" /> Now I want to be able to set the parameter from my code behind when I recieve an event - but it's not working: public string DescColText { set { this.Dispatcher.Invoke(DispatcherPriority.Normal, new Action(delegate() { DescriptionHeader = value; })); } }

  • Dealing with missing messages in JavaScript when using BOSH

    - by JamieD
    We recently went into private beta on our flagship product and had a small launch event. Unfortunately the venue had a terrible wireless connection and packets were being dropped left right and centre causing havoc with out system, basically it wasn't able to work at all! Luckily we were able to switch to a different network and rescue the demo. This highlighted something that I knew was already an issue but hadn't appreciated quite how much of an issue it could be. Our system relies heavily on BOSH and has a rather large JavaScript code base which now works rather well under good network conditions. However we need to make it work well under bad network conditions as well. Due to the way that XMPP works, a fire and forget system, it's not easy to tell if a message you sent, or were supposed to receive, was actually sent or received. For instance, we have an offer system, one user will send an offer to another over BOSH. When this message is received by the server a message is published to the offering users offers_sent PEP node and a similar message to the receiving users offers_received PEP node. While the sending user is able to tell if their offer was send (relatively) easily, if the notification to the receiving user is never received that user will never know it missed a message. A little about out JavaScript setup, it has 4 main layers: StropheJS An MVC framework for dealing with low level tasks and to build on top of An application layer which contains the app logic routes, controllers models etc. as well as a browser cache of the model data A UI layer that receives events and publishes events to and from the application layer One way to solve the missing messages issue would be to periodically check the PEP nodes for new data that the browser doesn't know about. If a new message was discovered the browsers cache would be invalidated and all new data would be requested from the server. I'm not sure this is the best way to go and it also doesn't cover all situations. We certainly don't want to get into the situation where we are sending messages to confirm the previous message was received at it's destination as this would double the network traffic. With the number of real time websites growing daily this is an issue that must have been encountered by other developers, it would be interesting to see how it's been solved by others. As far as I can see there are two situations in which messages go missing: On poor connections messages are not sent or received due to the packets being dropped Involving navigating between pages, a message is received by the browser but is not fully processed and stored in the local cache before the page is unloaded. Or a message is added to the send queue but never sent before the page is unloaded I suspect the hardest issue to solve will be number 2. Any thoughts on the subject would be much appreciated.

  • How do I register a server side click on an HTMLGenericControl?

    - by Brian Scott
    I'm looking for a reliable mechanism to generate a server side postback handler for an HTMLGenericControl such as an . I have some markup that I do not wish to change and would prefer to treat this in the same fashion as a standard .Net server control. Also, I know I can use a template based control to place some .Net controls within the markup as hidden and then trigger their click events from a client side click proxy. However, I'm really enquiring as to whether this can be done better.

  • More specific NSNumberFormatter failure behaviour

    - by Volte
    I have an NSTextField into which I need the user to enter a number between a max and min, and it would be nice if I could detect when the NSNumberFormatter fails that particular test so I can either display a nicer message ("The number is too large" is not very helpful, it needs to display the valid range) or simply set the field automatically to the nearest valid value. I've looked at the NSTextField delegate's -control:didFailToFormatString:errorDescription: method which doesn't seem to allow you to modify the error, and I've looked at overriding the NSNumberFormatter's -getObjectValue:forString:range:error: method which does give me an NSError that I can modify, but there doesn't seem to be any way to determine which specific error was returned. Since I am just entering a simple integer, I don't need most of the functionality in NSNumberFormatter, would I be better off just writing my own formatter from scratch?
