  • Simplest way to use NSTableView?

    - by Nick Brooks
    Can I use NSTableView like I've used ListView in Windows? By that I mean JUST adding rows to the view. I need to display a very simple two columned table and I don't want to write all this data related crap. Can I just 'add' stuff to a table view? If not what is the simplest way to do what I'm trying to do (preferably without data sources)?

  • iPhone OS: Get a list of methods and variables from anonymous object

    - by ChrisOPeterson
    I am building my first iPhone/Obj-c app and I have a large amount of data-holding subclasses that I am passing into a cite function. To the cite function these objects are anonymous and I need to find a way to access all the variables of each passed object. I have been using a pre-built NSArray and Selectors to do this but with more than 30 entries (and growing) it is kind of silly to do manually. There has to be a way to dynamically look up all the variables of an anonymous object. The obj-c runtime run-time docs mention this problem but from what I can tell this is not available in iPhone OS. If it is then I don't understand the implementation and need some guidance. A similar question was asked before but again I think they were talking about OSX and not iPhone. Any thoughts? -(NSString*)cite:(id)source { NSString *sourceClass = NSStringFromClass([source class]); // Runs through all the variables in the manually built methodList for(id method in methodList) { SEL x = NSSelectorFromString(method); // further implementation // Should be something like NSArray *methodList = [[NSArray alloc] initWithObjects:[source getVariableList]] for(id method in methodList) { SEL x = NSSelectorFromString(method); // Further implementation }

  • 3 embedded UIScrollView problem

    - by Infinity
    Hello guys! I have 3 UIScrollView. Here is a sample code, about how they are added in eachother: UIScrollView main; UIScrollView page1; UIScrollView page2; UIScrollView doublePage; UIView pageContent1; UIView pageContent2; UIView doublePageContent; int nrPages = 1; sw2 = 0; main = [[UIScrollView alloc] initWithFrame:CGRectMake(0.0, 0.0, 768, 980)]; main.contentSize = CGSizeMake(768 * (nrPages - 1 + sw2), 980); page1.frame = CGRectMake(0, 0, 768, 980); page2.frame = CGRectMake(768, 0, 768, 980); pageNumber = i - 1 + sw2; (i is a variable in a for loop) doublePage.frame = CGRectMake(768 * (pageNumber - 1), 0, 768 * 2, 980); CGFloat contentWidth = [page1 bounds].size.width + [page2 bounds].size.width; CGFloat contentHeight = page1 ? self.page1.bounds.size.height : self.page2.bounds.size.height; doublePageContent = [[UIView alloc] initWithFrame:CGRectMake(0, 0, contentWidth, contentHeight)]; [page1 addSubview:pageContent1]; [page2 addSubview:pageContent2]; [doublePageContent addSubview:page1]; [doublePageContent addSubview:page2]; [doublePage addSubview:doublePageContent]; [main addSubview:doublepage]; And with this structure the main scrollview don't want to scroll. Without the doublepage scrollview it is working good. What do you think? What's the problem? I know this structure is a little weird, but I need this structure because other parts of the code. Edited, added the information about the sizes. If you need something more please tell me. And one more thing.. If I add 1 pixel to the width of the doublePage contentSize.width it scrolls, but a bit hard, so it scrolls first in the doublePage and then in the main.

  • Core Data: Overkill for simple, static UITableView-based iPhone App?

    - by David Foster
    Hello! I have a rather simple iPhone app consisting of numerous views containing a single, grouped table view. These views are held together in navigation controllers which are grouped in a tab bar. Simple stuff. My table views do little more than list text (like "Dog", "Cat" and "Weasel") and this data is being served from a collection of plists. It's perhaps worth mentioning too that these tables are 'static' in the sense that their data is pre-determined and will only ever be amended—and if so, very rarely indeed—by the developer (in this case, moi). This rudimentary approach has reached its limits though, and I think I'm going to need something a bit more relational. I have worked a tad with Core Data in the past, but only with apps whose data is determined by user input. I have four closely related questions: Is Core Data overkill for an app consisting mainly of a selection of simple table views? Do you recommend using Core Data to manage data which is predetermine and extremely unlikely to ever change? Can one lock Core Data down so that its data can't change, thereby relinquishing my responsibility as the developer to handle the editing and saving of the managed object context? How do I go about giving Core Data my predetermined data, and in a format I know that it can work with? Thanks a bunch guys.

  • Emailing HTML from within an iPhone app is stopping at special characters

    - by user141146
    Hi, I have an iPhone app that will let users email some pre-determined text as HTML. I'm having a problem in that if the text contains special characters within the text (e.g., ampersand &, , <), the NSString variable that I use for sending the body of the email gets truncated at the special character. I'm not sure how to fix this (I tried using the method stringByAddingPercentEscapesUsingEncoding…but this hasn't fixed the problems). Thoughts on what I'm doing wrong / how to fix it? Here is sample code showing what I'm trying to do Thanks!!! - (void)send_an_email:(id)sender { NSString *subject_string = [NSString stringWithFormat:@"Summary of %@", commercial_name]; NSString *body_string = [NSString stringWithFormat:@"%@<br /><br />", [self.dl email_message]]; // email_message returns the body of text that should be shipped as html. If email_message contains special characters, the text truncates at the special character NSString *full_string = [NSString stringWithFormat:@"mailto:?to=&subject=%@&body=%@", [subject_string stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding], [body_string stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; [[UIApplication sharedApplication] openURL:[[NSURL alloc] initWithString:full_string]]; }

  • Call an IOUSBDeviceInterface function on an obj-c object instead of a C structure

    - by b1onic
    Let's say I want to close an USB device. Here is a C structure representing the USB device: struct __USBDevice { uint16_t idProduct; io_service_t usbService; IOUSBDeviceInterface **deviceHandle; IOUSBInterfaceInterface **interfaceHandle; Boolean open; }; typedef struct __USBDevice *USBDeviceRef; Here is the code to close the device: // device is a USBDeviceRef structure // USBDeviceClose is a function member of IOUSBDeviceInterface C Pseudoclass (*device->deviceHandle)->USBDeviceClose(device->deviceHandle); Now imagine that the device properties are declared in an obj-c class @interface Device : NSObject { NSNumber idProduct io_service_t usbService; IOUSBDeviceInterface **deviceHandle; IOUSBInterfaceInterface **interfaceHandle; BOOL open; } @end How would I do to call USBDeviceClose() ?

  • WebKitErrorDomain error 101

    The following code produces and error of: WebKitErrorDomain error 101 code: -(Void) searchBarSearchButtonClicked: (UISearchBar *) activeSearchBar { NSString * query = [searchBar.text stringByReplacingOccurrencesOfString: @ "" withString: @ "+"]; NSURL * url = [NSURL URLWithString: [NSString stringWithFormat: @ "http://http://www.google.com/search?q =%, query]]; NSURLRequest * requestObj = [NSURLRequest requestWithURL: url]; [Home loadRequest: requestObj]; } -(Void) loadView { [Super loadView]; CGRect bounds = [[UIScreen mainScreen] applicationFrame]; searchBar = [[UISearchBar alloc] initWithFrame: CGRectMake (0.0, 0.0, bounds.size.width, 48.0)]; searchBar.delegate = self; [Self.view addSubview: searchBar]; } I don't speak english and rely on a translator. Because of the language issue could this be a keyboard problem, or an encoding problem?

  • iPhone: AppStore InAppPurchase Connects in Simulator but Not on Device

    - by riteshkumar1905
    I am having trouble connecting to the AppStore from within my application. Everything runs fine in the Simulator but when I run on device the app cannot connect to the Appstore. Here is the code that connects to the Appstore #import "BuyController.h"#import "InAppPurchaseManager.h" #import "SKProducts.h" #define kInAppPurchaseProUpgradeProductId @"com.vigyaapan.iWorkOut1" @implementation BuyController - (IBAction)buy:(id)sender{ /* get the product description (defined in early sections)*/ //[self requestProUpgradeProductData]; if ([SKPaymentQueue canMakePayments]) { InAppPurchaseManager *Observer = [[InAppPurchaseManager alloc] init]; [[SKPaymentQueue defaultQueue] addTransactionObserver:Observer]; //NSURL *sandboxStoreURL = [[NSURL alloc]initWithString:@"http://sandbox.itunes.apple.com/verifyReceipt"]; //[[UIApplication sharedApplication]openURL:[NSURL URLWithString:@"http://sandbox.itunes.apple.com"]]; [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://phobos.apple.com/WebObjects/ com.vigyaapan.iWorkOut1?id=9820091347&;amp;amp;amp;amp;mt=8"]]; //[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=301349397&;amp;amp;amp;amp;mt=8"]]; SKPayment *payment = [SKPayment paymentWithProductIdentifier:@"com.vigyaapan.iWorkOut1"]; [[SKPaymentQueue defaultQueue] addPayment:payment]; } else { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"MyApp" message:@"You are not authorized to purchase from AppStore" delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil]; [alert show]; [alert release]; } //return [SKPaymentQueue canMakePayments];} SKPayment *payment = [SKPayment paymentWithProductIdentifier:kInAppPurchaseProUpgradeProductId]; [[SKPaymentQueue defaultQueue] addPayment:payment]; //[self requestProUpgradeProductData]; /* get the product description (defined in early sections)*/ } @end

  • Disable animation when moving CALayers

    The following code animates the movement, even though I didn't use beginAnimations:context. How do I get it to move without animating? This is a new iphone view project, and these are the only updates to it. // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; sublayer = [CALayer new]; sublayer.backgroundColor = [[UIColor redColor] CGColor]; sublayer.frame = CGRectMake(0, 0, 100, 100); [self.view.layer addSublayer:sublayer]; } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { sublayer.position = [[touches anyObject] locationInView:self.view]; }

  • Implementing scroll view that is much larger than the screen view with random images

    - by pulegium
    What I'm trying to do is to implement something like the fruit machine scroll view. Basically I have a sequence of images (randomly generated on the fly) and I want to allow the users to scroll through this line. There can fit approx 10 images on the screen, but the line is virtually unlimited. My question is what would be the best approach in implementing this? So far I've thought of having a UIImageView going across the screen (with width equal to the sum of 10 images) and the image associated with it would be a combination of 12 or so images, with two images falling out of the visible area, this would allow for smooth scrolling. If the user scrolls further, then I would reconstruct the image associated with the view so the new images are appended and the old one's are discarded. This image reconstruction business sounds bit complicated, so I was wondering if there's a more logical way to implement this. There's one more thing, I want to have two lines crossing each other with images, bit like conveyor belts crossing. If that makes any sense... Bit like below: V1 V2 H1 H2 H3 H4 H5 V4 V5 So if the vertical belt is moved it'd be like: V2 H3 H1 H2 V4 H4 H5 V5 V6 H1-H5, V1-V6 being automatically generated images. I'm not asking for the implementation code, just the thoughts on the principles how to implement this. Thanks!! :)

Does anyone know how to pull the filename from the core data object. something like this would be great... NSLog (@"the filename is %@", [coreData filename]); Any ideas?

  • How to avoid piracy in iPhone apps by server side validation?

    - by prathumca
    As par my app requirement, there is a couple of scenarios that I need to handle. Scenario 1: To avoid piracy, I want to include some piece of code, whose job is sending both IMEI and Serial number of IPhone. Scenario 2: At server side, I've a database, which has a list of both IMEI and Serial No info. Here I wanna validate both IMEI and Serial numbers. If both are not matched then I can make sure that the app is pirated. Idea seems good. But I don't know how to handle these two scenarios in my app. Any help is greatly appreciated.

  • How to access core data objects from Javascript?

    - by Eli
    How can I gain access to Core Data objects from Javascript/WebKit on Mac OS X? I've made custom subclasses of NSManagedObject for each of my tables, with accessors defined using @property/@dynamic for each attribute, but neither isSelectorExcludedFromWebScript: or isKeyExcludedFromWebScript: is called for any of them, so Javascript just stops when I try to access any of the attributes. It returns 'undefined' if I access it as a property (eg business.name ) and javascript execution stops if I access it as a function (eg business.name() ).

  • Objects in interface

    - by Peter Kowalchuk
    I created my own object, PKSurvey. In the interface of the View Controller I can define a pointer to it, then in a method I can alloc it and have an instance. How do I keep the instance beyond the method where it was allocated? I assign values in one method and want to be able to use those values in other methods. Should I allocate it in the viewDidLoad method or should I do it somewhere else? @interface DIrectionalDrillerViewController : UIViewController { PKSurvey *Survey=[PKSurvey new]; ---------------- - (void)viewDidLoad { [Survey new];

  • UILabel: Using the userInteractionEnabled method on a label

    - by Kevin Bomberry
    Hello again. I am wondering if anyone has used the userInteractionEnabled method on a UILabel to allow the label to act like a button (or just to fire off a method). Any help would be greatly appreciated. Cheers! Update (4/30/09 @1:07pm) Clarification: I have a standard InfoButton and next to it I want to place a label with the text "settings" and I would like the label to function like the button (which flips over to a settings screen. So, basically I need to tie the already defined showSettinsView to the "infoLabel" label; a user clicks on the infoButton or infoLabel and the method fires off. The infoButton is already working and is using an IBAction to trigger the method. I would like to know how to wire up the label to implement the same method. That is all. Cheers!

  • iPhone checklist app

    - by Brodie4598
    I am trying to create a simple app that displays a list of items with check boxes next to each item, then give the user to simply check each box. Nothing (aside from the checkbox image switching) needs to happen when the check box is touched. Each checklist is a seperate NSDictionary contained in a single master NSDictionary. The checklist dictionary contains arrays for different sections of each checklist. At the top of the view, the user selects which set (dictionary) of checklists they want to open then I want that checklist to display underneath the picker once a "select checklist" button is pressed. Any ideas on the best way to get this done?
