  • How can I make a UIPickerView like a UIDatePicker?

    - by iamthepiguy
    I have a custom UIViewController subclass which acts as Datasource and Delegate for a UIPickerView which I would like to serve two different purposes, as each are simple enough, and don't really warrant separate files. One operation must be as a custom picker, and this works fine. However, for the other operation, I want it to act just like a UIDatePicker. The problem is, UIDatePicker is a subclass of UIControl, not UIPickerView. Is there any sort of enum value I can set in a method (or other way) that will set the UIPickerView to act as a date picker? Or do I have to make two completely different classes and use them differently (pain in the ass)?

  • Ideas for loading initial data in an iPhone application?

    - by Derek Clarkson
    Hi all, In my app I want to load some initial data to show the user how it works. The app uses a CoreData managed sqllite db. SO far I've thought of 3 options: Write code into a class to programmatically create the data. Create a xml file in the apps resources and load through a NSXmlParser whose delegate creates the entries in the sqllite db. Same as option #2, but use a json file and bring in a 3rd party lib to read it. Are there other options I have not found yet? and given that I'm talking about perhaps 6 records per table when there are 3 tables, which would you choose?

    - by Dale
    Does anybody know if you can access the SaevFileDialog control that's used by the WebBrowser control? Once somebody saves the webpage being displayed I need to catch where the files have been created; however I can't seem to find any events/members that allow me access to that information.

    - by Broken Pipe
    I'm trying to figure out hot to create ItemsControl which contains Button near each Item, clicking on it removes this item from ItemsControl. I'm new to Silverlight|WPF is it possible to create this using just ControlTemplate? I tried to create inherited ListBox with ControlTemplate that renders button near each item and then i was supposed to hook to click event get item and remove it, but I neither found a way to render button near each item, neither how to subscribe to events from ControlTemplate ;-)

  • Validation and Firefox's input caching

    - by Chris Simpson
    When you refresh/reload a page or use the back button, Firefox is kind enough to repopulate your inputs with what was entered before you navigated away. Though this is a nice feature it does not trigger my jquery validation and the unsaved changes warning I add to my pages. Is there a way to either disable this feature in Firefox (without renaming every control every time) or capture the firefox events?

  • Cocoa Bindings in the face of a million of items in an NSArray

    - by François Beausoleil
    I'm writing a GUI for MongoDB using Cocoa. It's going well, but I don't know how to make KVO properties that would be lazily loaded. How does one handle that? For instance, viewing the documents in a Mongo collection. The collection might have a million items in it. I suspect I shouldn't be downloading the full 2-5 GiB of data to my Cocoa app, then format and display 20 rows. How does one implement that? I called my project Mongo Explorer, available on GitHub. Specifically, how would I code MECollection#reload to be lazy? Do I need to implement a data source delegate for my NSTableView?

  • Passing Global Variable value to Facebook - Gets NULL only

    - by Viral
    hi all friends, I am making a game application in that I want to pass my score on wall of face book. I've completed all the things (the log in and message passing part) but when I passes the score via global variable, I am getting only null as a value and not the score that I want. Is there any way to pass data or string to Face book and write on a wall? My code is (void)viewDidLoad { static NSString* kApiKey = @"be60415be308e2b44c0ac1db83fe486b"; static NSString* kApiSecret = @"4f880c7e100321f808c41b1d3c813dfa"; _session = [[FBSession sessionForApplication:kApiKey secret:kApiSecret delegate:self] retain]; score = [NSString stringWithFormat:@"%@",appDelegate.myTextView]; [_session resume]; [super viewDidLoad]; } whre score is NSString and myTextView is NSString in other viewcontrollerfile, And appDelegate is global variable. Any help?? thanks in advance.

  • Real world examples of Rx

    - by theburningmonk
    I've been playing around with the Reactive Extension for a little while now, but mostly limited to handling/composing user driven events within a WPF frontend. It's such a powerful, new way of doing async programming, and I'm curious as to what other people are doing with it, and where do you think it might be able to improve the way we're currently doing things?

  • Unexpected key-value behavior in a Core Data Context

    - by ????
    If I create an array of strings (via key-value coding) containing the names of a Managed Object entity's attributes which are stored in the App Delegate the first time, I get an array of NSStrings without any problems. If I subsequently make the same call later from the same entry point in code, that same collection becomes an array of NULL objects- even though nothing in the Core Data Context has changed. One unappealing work-around involves re-creating the string array every time, but I'm wondering if anyone has a guess as to what's happening behind the scenes. // Return an array of strings with the names of attributes the Activity entity - (NSArray *)activityAttributeNames { #pragma mark ALWAYS REFRESH THE ENTITY NAMES? //if (activityAttributeNames == nil) { // Create an entity pointer for Activity NSEntityDescription *entity = [NSEntityDescription entityForName:@"Activity" inManagedObjectContext:managedObjectContext]; NSArray *entityAttributeArray = [[NSArray alloc] initWithArray:[[entity attributesByName] allValues]]; // Extract the names of the attributes with Key-Value Coding activityAttributeNames = [entityAttributeArray valueForKeyPath:@"name"]; [entityAttributeArray release]; //} return activityAttributeNames; }

  • How can I draw a shadow beyond a UIView's bounds?

    - by Christian
    I'm using the method described at http://stackoverflow.com/questions/805872/how-do-i-draw-a-shadow-under-a-uiview to draw shadow behind a view's content. The shadow is clipped to the view's bounds, although I disabled "Clip Subviews" in Interface Builder for the view. Is it possible to draw a shadow around a view and not only in a view? I don't want to draw the shadow inside the view because the view would receive touch events for the shadow area, which really belongs to the background.

  • How to detect when the screen is on?

    - by Jim Blackler
    As mentioned in a previous question, I am having difficulty intercepting all android.intent.action.SCREEN_ON events without a long-lived service (discouraged). I may be able to work around the need if I can simply work out when the screen is on at any given time, in the service. Can anyone suggesting a method call that would return this information? 1.5 upwards.

  • Code Interaction with Quartz Composition

    - by Alberto MQO
    Hi, i have a Quartz Composition with a Cube, and X/Y/Z rotation inputs are published. On Interface Builder i made a QCView and a QCPatchController with the previous Quartz Composition loaded. In QCView the Patch Controller is binded, and the rotation published ports are binded too to three NSSlider, so when i change the value of the NSSlider's then the cube rotates. All this works fine, but i want to change the rotation values of the cube from the App Delegate on XCode. I tried to change the value of the NSSliders with IBoulets pointing to them, but this change doesnt apply to the cube, like it does when i change the Sliders directly with my mouse. What should i instanciate and/or how to access and change this Input_Ports.value throught the CQPatchController? Thank you very much for reading, i really need help!

  • Replace Infinite loop in Flex

    - by H P
    Hello, I want to access a webservice:getMonitorData() , on creationcomplete and returns an array, in an infinite loop so that the getIndex0.text is updated each time. Flex is not able to handle an infinite loop and gives a timeout error 1502. If I run the for loop until i<2000 or so it works fine. How can replace the loop so that my webservice is accessed continiously and the result is shown in getIndex0.text.

  • How to cancel a touch sequence

    - by Alex
    I have an UIImage view that responds to touch events. I want to cancel the touch sequence if the touch goes outside of certain bounds. How can I do that? I know that I can inspect the coordinates of the touch object, what I don't know is how to cancel the sequence. I don't see any event in the API that allows for that.
