  • NSSortdescriptor, finding the path to the key I wish to use for sorting.

    - by RickiG
    Hi I am using an NSSortdescriptor to sort a collection of NSArrays, I then came across a case where the particular NSArray to be sorted contains an NSDictionary who contains an NSDictionary. I would like to sort from the string paired with a key in the last dictionary. This is how I would reference the string: NSDictionary *productDict = [MyArray objectAtIndex:index]; NSString *dealerName = [[productDict objectForKey:@"dealer"] objectForKey:@"name"]; How would I use the dealerName in my NSSortdescriptor to sort the array? NSSortDescriptor * sortDesc = [[NSSortDescriptor alloc] initWithKey:/* ? */ ascending:YES]; sortedDealerArray = [value sortedArrayUsingDescriptors:sortDesc]; [sortDesc release]; Hope someone could help me a bit with how I go about sorting according to keys inside objects inside other objects:) Thank you.

  • How to release audio properly? (AVAudioPlayer)

    - by Aluminum
    Hello everyone! I need help with my iOS application ^^,. I want to know if I'm releasing AVAudioPlayer correctly. MyViewController.h #import <UIKit/UIKit.h> @interface MyViewController : UIViewController { NSString *Path; } - (IBAction)Playsound; @end MyViewController.m #import <AVFoundation/AVAudioPlayer.h> #import "MyViewController.h" @implementation MyViewController AVAudioPlayer *Media; - (IBAction)Playsound { Path = [[NSBundle mainBundle] pathForResource:@"Sound" ofType:@"wav"]; Media = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:Path] error:NULL]; [Media play]; } - (void)dealloc { [Media release]; [super viewDidUnload]; } @end

  • iPhone SDK - How to display a photo taken with the camera inside a UINavigationController?

    - by dan
    This is my code so far: /* class: myViewController @interface myViewController: UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate> */ - (IBAction) getPicture { UIImagePickerController * picker = [[UIImagePickerController alloc] init]; picker.delegate = self; picker.sourceType = UIImagePickerControllerSourceTypeCamera; [self presentModalViewController:picker animated:YES]; } - (void) imagePickerController:(UIImagePickerController *)thePicker didFinishPickingMediaWithInfo:(NSDictionary *)imageInfo { [[thePicker parentViewController] dismissModalViewControllerAnimated:YES]; UIImage *img = [imageInfo objectForKey:@"UIImagePickerControllerOriginalImage"]; self.myImageView.image = img; } So basically I'm trying to get a photo from the iPhone camera and display it in a UIImageView. This works perfectly fine as long the class myViewController is displayed as a standalone view. If I'm putting the View inside a UINavigationController the UIImageView won't display the image after taking one with the camera. But if I choose a picture from the library everything is fine again. So why does the UIImageView won't display a image taken with the camera inside a UINavigationController?

  • Using intermediate array for hashCode and equals

    - by Basilevs
    As its a pain to handle structural changes of the class in two places I often do: class A { private B bChild; private C cChild; private Object[] structure() { return new Object[]{bChild, cChild}; } int hashCode() { Arrays.hashCode(structure); } boolean equals(Object that) { return Arrays.equals(this.structure(), ((A)that).structure()); } } What's bad about this approach besides boxing of primitives? Can it be improved?

  • Why does initWithFrame have the wrong frame value?

    - by greypoint
    I have a subclass of UIButton called INMenuCard and I am overriding the initWithFrame to include an activity indicator. The menuCard places correctly but any internal reference to "frame" give me "inf,inf,0,0" which means my activityIndicator subview is not placed correctly. What might I be missing? @implementation INMenuCard - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { CGRect innerFrame = CGRectInset(frame, 50.0f, 100.0f); activityIndicator = [[UIActivityIndicatorView alloc] initWithFrame:innerFrame]; activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhite; [self addSubview:activityIndicator]; } return self; } I am instantiating INMenuCard with (debugging shows the CGRect values are correct): CGRect cardFrame = CGRectMake(cardX, cardStartY, cardWidth, cardHeight); INMenuCard *menuCard = [[INMenuCard buttonWithType:UIButtonTypeCustom] initWithFrame:cardFrame]; [theView addSubView:menuCard];

  • iphone view controller class - how to

    - by Brodie4598
    Hello - I need to create my own UIView class and it is not something I have had to do. I created the class, then laid out the small view in IB (it's just a few labels that i will later need to add data to ). but now im stuck on how to actually put an instance of it in my main view. Can someone point me in the direction of a good tutorial? The closest thing I have done to this is creating a custom tableViewCell. DataTagViewController *dataTag = [[DataTagViewController alloc]init]; [theMap addSubView: dataTag];

  • What is the cost of object creating.

    - by Tony
    Hi If I have to choose between static method and creating an instance and use instance method, I will choose static methods always. but what is the detailed overhead of creating an instance? for example I saw a DAL which can be done with static classes but they choose to make it instance now in the BLL at every single call they call something like. new Customer().GetData(); how far this can be bad? Thanks

  • SEO - List of links

    - by Rafael Carvalho
    I'd like to know if listing a set of partner sites/blogs is useful for the pagerank growth. Does Google see it as an incorrect act? I read somewhere that if people exchange links, google seeks it and marks as a bad technique. If it doesn't matter, is the content of the linked site relevant?

  • Problems with UITableView when loading the view into the main window

    - by GuidoMB
    I've created a sub class of UITableViewController named LoginViewController with the XIB file using XCode. Then I opened the XIB file with IB and set the table's style to grouped. Finally I wrote the following code: - (void)applicationDidFinishLaunching:(UIApplication *)application { LoginViewController *loginViewController = [[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:[NSBundle mainBundle]]; [window addSubview: loginViewController.view]; window.backgroundColor = [UIColor blueColor]; [window makeKeyAndVisible]; [window layoutSubviews]; } I set the window's background color to blue for you to see what the problem is. I put a link to the screenshot If I don't use the table style grouped the problem does not occur

  • Simple Ruby Command Line Question

    - by aronchick
    Um - I feel like an idiot, but.... ruby -e '3+5' Outputs nothing (Windows 7, Ruby 1.8.7, Cygwin or Git Bash). What am I missing? Extra credit - will this also allow the extra cool bundle (stolen from TextMate) Execute and Update # = markers to work properly? EDIT Ok that worked, and I'll accept the answer, but e-texteditor still doesn't work with that really cool bundle. Too bad.

  • Is it a good idea for me to learn Python before C or some other Compiler language?

    - by Dream Lane
    Right now I am going through MIT's introduction to Computer Science course via OpenCourseWare. As a part of this course I am learning the Python Language. I've read a lot of things about the benefits of learning C. Before I dig any deeper into Python I wonder if I will be hindered or helped by learning Python first. Do you think that I will develop any bad habits or anything like that from Python?

  • detecting when nav controller popped to root

    - by phil swenson
    Here is my code: SignupController* signupController = [[SignupController alloc] initWithNibName:@"SignupController" bundle:nil]; [window addSubview:[navigationController view]]; [window makeKeyAndVisible]; self.navigationController.title = @"MyNavController"; [self.navigationController pushViewController:signupController animated:YES]; [signupController release]; Unfortunately for me calling pushViewController is not synchronous, so the next line ([signupController release]) is executed immediately. I need to detect hen the signupController has popped back to the root so I can take the data from the signup controller and do a registration or login. Any ideas? Thanks

  • Disable link in UIWebView in appearance and function

    - by Peter
    Hello, I wish to disable the href links on a UIWebView. First, I want the look of the link to change so the user doesn't think it is clickable. Second, I want the actual link to not be able to be tapped. I do not want to try webView:shouldStartLoadWithRequest:navigationType: since that not change the appearance of my links. I found this answer: Disabling visible links in UIWebView But the above hasn't worked for me. This is my code: NSString* s=[[NSString alloc] initWithFormat:@"for (a in document.getElementsByTagName(\"a\")) {a.href = \"\";}"]; [myWebView stringByEvaluatingJavaScriptFromString:s]; I've been working on this for hours, any suggestions are appreciated! Thanks!

  • How to create an image from canvas data?

    - by Jakub Hampl
    In my application I am trying to save an arbitrary part of a rendered HTML canvas to an image file. In my Javascript I call ctx.getImageData(x, y, w, h) and pass the resulting object to my macruby code (though if you know a solution in objc I am also very interested). There I'm trying to create a NSBitmapImageRep object so that I can then save to an image format the user desires. This is my code so far (the function gets a WebScriptObject as it's argument): def setimagedata(d) w = d.valueForKey("width").to_i h = d.valueForKey("height").to_i data = Pointer.new(:char, d.valueForKey("data").valueForKey("length").to_i) d.valueForKey("data").valueForKey("length").to_i.times do |i| data[i] = d.valueForKey("data").webScriptValueAtIndex(i).to_i end puts "data complete" # get's called @exported_image = NSBitmapImageRep.alloc.initWithBitmapDataPlanes(data, pixelsWide: w, pixelsHigh:h, bitsPerSample: 32, samplesPerPixel: 4, hasAlpha: true, isPlanar: false, colorSpaceName: NSCalibratedRGBColorSpace, bitmapFormat: NSAlphaNonpremultipliedBitmapFormat, bytesPerRow: 0, bitsPerPixel: 0) puts "done" # doesn't get called end The code doesn't seem to get through the initWithBitmapDataPlanes function but gives no error. My question is: what am I doing wrong? Is this approach reasonable (if not, what would be better?).
