  • iPhone. Open application during call

    - by immuner
    Is there any way to do this? In other words, is it possible during a call to allow the user to open a certain application? (for example, to provide information based on the person who is calling). If not, will something like this be available on iOS 4?

  • Using iPhone Core Data to many Relationship

    - by BLeB
    When I define a to many relationship between entities in Xcode and then generate the data class from the entity I get a header with the following methods defined: @interface PriceList (CoreDataGeneratedAccessors) - (void)addItemsObject:(PriceListItem *)value; - (void)removeItemsObject:(PriceListItem *)value; - (void)addItems:(NSSet *)value; - (void)removeItems:(NSSet *)value; @end When I attempt to call addItemsObject with the following code a doesNotRecognizeSelector exception is thrown. PriceListItem *item = [NSEntityDescription insertNewObjectForEntityForName:@"PriceListItem" inManagedObjectContext:managedObjectContext]; item.cat = [attributeDict valueForKey:@"c"]; item.sel = [attributeDict valueForKey:@"s"]; [self addItemsObject:item]; From what I have read I do not have to implement these methods and that they are generated at runtime. Any ideas?

  • Detect iphone region

    - by camilo
    Hi. In my app, the user is supposed to insert a phone number, which is then displayed somewhere else. In the contacts application, when displaying a phone number, it automatically appears in the format of the language selected by the user. Is there a way to do this automatically, or a way to detect the region and then adapt the displayed string?

  • Square collision detection problem (iPhone).

    - by thyrgle
    Hi, I know I've probably posted three questions related to this then deleted them, but thats only because I solved them before I got an answer. But, this one I can not solve and I don't believe it is that hard compared to the others. So, with out further ado, here is my problem: So I am using Cocos2d and one of the major problem is they don't have buttons. To compensate for there lack in buttons I am trying to detect if when a touch ended did it collide with a square (the button). Here is my code: - (void)ccTouchesEnded:(NSSet*)touches withEvent:(UIEvent*)event { UITouch *touch = [touches anyObject]; CGPoint location = [touch locationInView:touch.view]; NSLog(@"%f", 240-location.y); if (isReady == YES) { if (((240-location.y) <= (240-StartButton.position.x - 100) || -(240-location.y) >= (240-StartButton.position.x) + 100) && ((160-location.x) <= (160-StartButton.position.y) - 25 || (160-location.x) >= (160-StartButton.position.y) + 25)) { NSLog(@"Coll:%f", 240-StartButton.position.x); CCScene *scene = [PlayScene node]; [[CCDirector sharedDirector] replaceScene:[CCZoomFlipAngularTransition transitionWithDuration:2.0f scene:scene orientation:kOrientationRightOver]]; } } } Do you know what I am doing wrong?

  • Chaining Animations (iPhone / MonoTouch)

    - by ifwdev
    I'm trying to slide some (custom) tab-like buttons into view. I don't want them all to move at the same time. Also, they shouldn't move one at at time (where one slides after the other finishes). I want each button to begin sliding slightly after the previous. Preferably it would happen on a curve but just a fixed .1 second offset would be alright too. Monotouch or Obj-C code is fine. I'm thinking there is something in the APIs for animating groups of items like this. Hopefully, at least...

  • iPhone view architecture question

    - by Joe
    So I have (for instance) three views: A: root view B: a view functionally identical to root C: a data entry view which collects a few piece of info What I'm trying to do is reuse C to supply the data it collects to either A or B. It should supply the data to whichever of the two it is pushed onto. The data for A is similar, but functionally distinct, to what collects for B. Right now, I'm passing data from C to A or B via a singleton class. What I'm trying to avoid is having two instances of C, one to supply data to A and B (because, in actuality, the program will have 5 total views like C. Does the question make sense?

  • iphone - Images (slide show) and audio snychronization

    - by Qaiser
    I have 20 images and some audio. I would like to show a single image at a time and change the images at (unequal) intervals. For example, I want to show image 1 for 1.44 seconds and image 2 for 1.67 seconds and so on. Can someone suggest how to go about doing this please? What I have seen are examples that show how to setup an array of images with one field that denotes total time. This causes the images to show for an equal amount of time (each). ... and that not what I am looking for ...

  • How to take a screen shot in iPhone via code

    - by Radix
    Hello friends; I am working on an app and am almost done with it, but the only thing pending is that i am not able to take screen shots of my screen on the touch of the UIButton object. I have saw a code available which said to use UIGetScreenImage(), but alas that didn't worked fine. I want to take the screen shot and display it in the UIImageView. So can you please provide me with the link or code to do the same, that would be really nice of you Thanks & Regards Radix

  • Basic string and value functions in Objective-C for iPhone

    - by David Maitland
    I have very little programming knowledge; only a fair bit in Visual Basic. How do I take a value from a text field, then do some simple math such as divide the value by two, then display it back to the user in the same field? In Visual Basic you could just do txtBoxOne.text = txtBoxOne.text / 2 I understand this question is more than one question and is very basic stuff, but I need to get my head out of Visual Basic and into where I should be :)

  • IPhone geo tagging data (SQLite or CoreData)

    - by user267980
    Hi. I'm about to build an app that has a database of places that has a location (lon/lat) and i'm about to build the dataModel. Actualy the app is very simple and all i want is to be able to fetch all places around the user (say in a radius of 30miles). Is it better to user SQLite (is there any geo-spatial extension out there)? I'll have around 5000 places in the database and i'm wondering where i can ask a database without affecting performances.

  • iPhone loading view from nib only works once

    - by The Swissdude
    Hi Forum I'm trying to add a «loader-view» to my app which shows a spinner while doing stuff. This works fine the first time, but it doesn't work a second time. here's what I do: I have a viewController for the spinner (spinnerViewController) and a nib-file which I made in IB (spinner.xib). I load the nib in the viewDidLoad-event: spinnerView = [[spinnerViewController alloc] initWithNibName:@"spinner" bundle:nil]; [spinnerView retain]; spinnerView is declared in the .h-file (spinnerViewController *spinnerView;) next, I show the spinner-view: [self.view addSubview:spinnerView.view]; [self.view bringSubviewToFront:spinnerView.view]; which works fine... And now the trouble starts. No matter what I do, I can't show the spinner view again. I tried just hiding it (self.view sendSubViewToBack: spinnerView.view) which works for hiding, but when I try to bring it to the front again (self.view bringSubViewToFront: spinnerView.view) it doesn't work. I also tried removing the spinner-view and add it again with no success (within the spinnerViewController: [self.view removeFromSuperview] and to show it again [self.view addSubview... ) Any ideas what I'm doing wrong??? ;) Thanks for the help!

  • Keeping object in memory (iPhone SDK)

    - by Chris
    I am trying to create a UIImageView called theImageView in the touchesBegan method that I can then then move to a new location in touchesMoved. Currently I am receiving an "undeclared" error in touchesMoved where I set the new location for theImageView. What can I do to keep theImageView in memory between these two methods? - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { ... UIImageView *theImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"]]; theImageView.frame = CGRectMake(263, 228, 193, 300); [theImageView retain]; ... } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { ... theImageView.frame = CGRectMake(300, 300, 193, 300); ... }

  • iPhone SDK: Keep an image from scrolling with a UIScrollView

    - by Wudstock
    Hi, I've been searching all over for an easy way to do this. Right now I have a UIScrollView setup as my main view. There's an Image on the left and a column of TextFields on the right. When any TextField is tapped, the keyboard comes up and hides the bottom TextField. So I have the ScrollView move up to unhide the bottom TextField. Question #1: Is there a way to have it respond to a specific TextField instead of all of them? Question #2: Is there a way to keep the Image on the left static so it doesn't move with the TextFields? Thanks in advance for any help.
