  • How to play sound automatically when scrolling to the next page?

    - by viper15
    I'm using Page Control example from Apple. I want to be able to scroll horizontally to certain page and get the sound automatically play when viewing that page? And then sound stop when viewing the other page? So, for example. On page 1, i have some texts. When i go to the next page which is on page 2, i want sound to be automatically play and stop when i go to page 3. I'm planning to use If statements (since it's not that many pages) to determine which page will get the sound. My question is simple. How do you get the sound play automatically when viewing certain page? By the way, I'm planning to use System Sound. I know how to play the sound using button. But how do you get it automatically - start when certain page appear and stop when moving to the next page. Thank you in advance! Edited: I put in this code in ViewDidLoad but the sound played on sooner before it reach the page intended: // Set the label and background color when the view has finished loading. - (void)viewDidLoad { pageNumberLabel.text = [NSString stringWithFormat:@"Page %d", pageNumber + 1]; self.view.backgroundColor = [MyViewController pageControlColorWithIndex:pageNumber]; if (pageNumber == 3) { NSString *path = [[NSBundle mainBundle] pathForResource:@"crunch" ofType:@"wav"]; SystemSoundID soundID; AudioServicesCreateSystemSoundID((CFURLRef)[NSURL fileURLWithPath:path], &soundID); AudioServicesPlaySystemSound(soundID); } }

  • UITableView: Highlighted cell after switching back views

    - by Matthias
    Hi, I'm using a UINavController together with some UITableViews to display a kind of drill down for some data (e.g. like the Contact App). Works well. The only problem I have is, when I select a cell in the first table view it is highlighted, then the view switches to the next level and then, if I go back to the first level, the cell is still highlighted. So, how can I reset the highlighting when switching back? Thanks for your help. Regards Matthias

  • Stop lazy-loading images?

    - by Greg
    Here's the issue – I followed along with the Apple lazy-load image sample code to handle my graphical tables. It works great. However, my lazy-load image tables are being stacked within a navigation controller so that you can move in and out of menus. While all this works, I'm getting a persistent crash when I move into a table then move immediately back out of it using the "back" button. This appears to be a result of the network connections loading content not being closed properly, or calling back to their released delegates. Now, I've tried working through this and carefully setting all delegates to nil and calling close on all open network connections before releasing a menu. However, I'm still getting the error. Also – short posting my entire application code into this post, I can't really post a specific code snippet that illustrates this situation. I wonder if anyone has ideas for tasks that I may be missing? Do I need to do anything to close a network connection other than closing it and setting it to nil? Also, I'm new to debugging tools – can anyone suggest a good tool to use to watch network connections and see what's causing them to fail? Thanks!

  • Assign TableView column binding to a specific core-data object in to-many related entity based on se

    - by snown27
    How would I assign a column of a TableView to be a specific entry in a Core Data entity that is linked to the NSArrayController via a to-many relationship? For example Entity: MovieEntity Attributes: title(NSString), releaseDate(NSDate) Relationship: posters<-->> PosterEntity Entity:PosterEntity Attributes: imageLocation(NSURL), default(BOOL) Relationships: movie<<--> MovieEntity So I have a three column table that I want to display the Poster, Title, and Release Date attributes in, but as one movie could potentially have several different style's of posters how do I get the poster column to only show the one that's marked default? Since the rest of the table is defined in Interface Builder I would prefer to keep it that way for the sake of keeping the code as clean as possible, but if this can only be done programmatically then I'm all ears. I just wanted to give preference in case there's more than one way to skin a cat, so to speak.

  • How do IOS know which viewController is being viewed and hence need viewWillAppear to be called

    - by Jim Thio
    How does iOs know? Does each view has a pointer to it's controller? What happened? When we pop a viewController from navigation, does the navigationController arrange which view should be called? For example: If I added: [[BNUtilitiesQuick window] addSubview:[BNUtilitiesQuick searchController].view]; viewWillAppear will be called. However, window doesn't know the viewController. I am passing the view outlet of the controller not the controller. How can iOs 5 knows that it has to call [[BNUtilitiesQuick searchController] viewWillAppear:YES]

  • Format textfield while typing Ios

    - by BBios
    Ive seen other examples and tried - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string I am not sure what I am doing wrong, I just started coding my first Iphone App This is what I am trying to do I have 4 textfields and each has a limit on number of letters while typing I have done this using the below code - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { int valid; NSString *cs2 = [textField.text stringByReplacingCharactersInRange:range withString:string]; // int charCount = [cs2 length]; if(textField == cvv){ valid = 4; }else if(textField == cardName) { valid=26; }else if(textField == expDate) { valid=5; // if (charCount == 2 ) { // textField.text = [cs2 stringByAppendingString:@"/"]; // textField.text = cs2; // return YES; // } }else if(textField == acNumber) { valid=19; } return !([cs2 length] > valid); Works fine till here, I have a textfield where the user enters Exp date and would like to format it as if I am entering 112 then it should display as 01/12 and if I enter 2 then it should display as 1122 I tried checking if the length of the textfield value is 2 then append a / but then that gives me when I enter 12 it gives 11/22

  • [super init] and loading NIB / XIB files?

    - by fuzzygoat
    I am a little curious, I have a view controller class and an NIB/XIB (both are named "MapViewController") If I do the following it loads the NIB with the matching name. -(id)init { self = [super initWithNibName:@"MapViewController" bundle:nil]; if(self) { do things ... } return self; } if on the other hand I just specify [super init] does Xcode just look for a NIB that matches the name of the controller, is that how this is working? -(id)init { self = [super init]; if(self) { do things ... } return self; } cheers Gary.

  • Trouble using xib files in libraries

    - by flohei
    Hi there, I'm having some trouble working with libraries and included xib files. Let me explain my situation first. I've got a project that's running pretty good. Now I need a part of my project as a library for another customer who want's to use some of the functionality in his app. I've created a library with help of that highly recommended article. My customer should be able to initialize a main view controller like this: LibraryMainViewController *lmvc = [[LibraryMainViewController alloc] initWithNibName:@"LibraryMainViewController.xib" bundle:foo]; That for sure leads to an error when I try to present that view controller modally. I'm not sure what bundle I have to use here. I tried something like [NSBundle bundleForClass:[SomeClassInTheLibrary class]]; but that didn't solve the problem. I would be glad if someone could tell me how to actually use a xib file in that kind of situation. Thanks –f

  • Simple addView problem

    Hi there. I have a simple addView problem that is driving me nuts, I know I am overlooking something simple, perhaps another set of eyes can help. I have a Nib with a view that has a class identity set to TestView In my view controller, I use the following code: CGRect myRect = CGRectMake(0, 0, 320,240); TestView *myTest = [[TestView alloc] initWithFrame:myRect]; [self.view addSubview:myTest]; I have a NSLog in the TestView class's initWithFrame that fires when the above code is executed, but the view doesn't appear in the view controllers view. Thanks for your help.

  • Logging in to website with saved username and password

    - by DGund
    One of the functions of an app I am making involves logging the user into our Campus Portal website. For ease of use, the user may enter a username and password into the app once, and it will be saved for all future log-ins. When the user clicks a button, the information will automatically be sent to log in, and the website will be displayed in a UIWebView. Let us say that the username and password are each stored in an NSString. How can I use this data to log in to this website programmatically and display the page it in a UIWebView? I know little about posting and forms, so any help is appreciated. Would something like this Stackoverflow answer help? Here's the shell of my code for this - (IBAction)btnGo:(id)sender { username = usernameField.text; password = passwordField.text; if (saveSwitch.isOn) { //Save data if the user wants AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate]; usernameSaved = username; passwordSaved = password; [appDelegate.listOfPortalCredentials replaceObjectAtIndex:0 withObject:usernameSaved]; [appDelegate.listOfPortalCredentials replaceObjectAtIndex:1 withObject:passwordSaved]; } //Insert username and password to web form, log in to portal //This is where I need help }

  • 3d movement around a sphere

    - by user578954
    Hey guys, Im working in 3d for the first time in a long time. Basically im rotating a sphere and projecting x y z cords to place things on the surface based on the spheres X and Y rotation. Heres the code im using: #define piover180 0.01745329252f GLfloat cosy = cos(yrot * piover180); island[i].x = rad * sin(xrot * piover180)* cosy; island[i].y = rad * sin(yrot * piover180); island[i].z = rad * cos(xrot * piover180) * cosy; Problem is the Xrot positioning works fine but the Yrot placement always draw the objects into the north and south pole so they all cross at the top, which isnt correct for rotating. I need a way to solve this. Heres a picture to help explain http://llllost.com/shuttle/47bcde62.jpg Any help would be greatly appreciated, let me know if you need any more information

  • Can't add or remove object from NSMutableSet

    - by Dan Ray
    Check it: - (IBAction)toggleFavorite { DataManager *data = [DataManager sharedDataManager]; NSMutableSet *favorites = data.favorites; if (thisEvent.isFavorite == YES) { NSLog(@"Toggling off"); thisEvent.isFavorite = NO; [favorites removeObject:thisEvent.guid]; [favoriteIcon setImage:[UIImage imageNamed:@"notFavorite.png"] forState:UIControlStateNormal]; } else { NSLog(@"Toggling on, adding %@", thisEvent.guid); thisEvent.isFavorite = YES; [favorites addObject:thisEvent.guid]; [favoriteIcon setImage:[UIImage imageNamed:@"isFavorite.png"] forState:UIControlStateNormal]; } NSLog(@"favorites array now contains %d members", [favorites count]); } This is fired from a custom UIButton. The UI part works great--toggles the image used for the button, and I can see from other stuff that the thisEvent.isFavorite BOOL is toggling happily. I can also see in the debugger that I'm getting my DataManager singleton. But here's my NSLog: 2010-05-13 08:24:32.946 MyApp[924:207] Toggling on, adding 05db685f65e2 2010-05-13 08:24:32.947 MyApp[924:207] favorites array now contains 0 members 2010-05-13 08:24:33.666 MyApp[924:207] Toggling off 2010-05-13 08:24:33.666 MyApp[924:207] favorites array now contains 0 members 2010-05-13 08:24:34.060 MyApp[924:207] Toggling on, adding 05db685f65e2 2010-05-13 08:24:34.061 MyApp[924:207] favorites array now contains 0 members 2010-05-13 08:24:34.296 MyApp[924:207] Toggling off 2010-05-13 08:24:34.297 MyApp[924:207] favorites array now contains 0 members Worst part is, this USED to work, and I don't know what I did to break it.

  • iPhone SKD make the iPod controller appear

    - by nico
    Hi all, It's been a while I'm consulting stackoverflow, but this time I didn't find any answer :( My question is quite simple :) On an iPhone/iPod touch, play music. Double tap the home button while the music is playing. You will see appear a popup with the play/pause/next/previous buttons and a volume control. Do you know if it's possible to make this popup appear programmatically ? I mean, I would like to add a button in my app that will display the popup, avoiding the user to double tap the home button (most of them doesn't know this shortcut). Thank you in advance !

  • Extending a view to the left side, animated

    - by Heinrich
    Hi, I have a view that I want to extend on the left side using an animation. All borders but the left one should remain the same, so the x position and the width of the view are changing. I use this code: [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:5.0]; self.frame = CGRectMake(self.frame.origin.x-100, self.frame.origin.y, self.frame.size.width+100, self.frame.size.height); [UIView commitAnimations]; If I run this code, the width of the view is set to the new value immediately and then the view is moved to the new x point, but why? How can I change this behaviour? Thanks for your ideas!
