  • iPhone not returning to application after calling eMail send

    - by Bill
    I am sending an email from within my iPhone application. The eMail page pops up ok, I click on the Send button, the iPhone plays a whoosh sound, and the eMail actually arrives at the recipient. Unfortunately, the mail dialog still sits there unresponsive, and the only option - to click the home button - kills the app. Is there something else that needs to be specified to close the eMailMessage view? MFMailComposeViewController *eMailMessage; NSArray *toAddress; if ([MFMailComposeViewController canSendMail]) { toAddress = [NSArray arrayWithObject:@"[email protected]"]; eMailMessage = [[MFMailComposeViewController alloc] init]; [eMailMessage setToRecipients:toAddress]; [eMailMessage setSubject:@"Notification"]; [eMailMessage setMessageBody:@"Performed by ..." isHTML:NO]; [self presentModalViewController:eMailMessage animated:YES]; [eMailMessage release]; }

  • Functional programming approach for Java's input/output streams

    - by Elazar Leibovich
    I'm using Java's DataInputStream with scala to parse some simple binary file (which is very bad exprerience due to the lack of unsigned types, even in scala, but that's a different story). However I find myself forced to use mutable data structure, since Java's streams are inherently state preserving entities. What's a good design to wrap Java's streams with nice functional data structure?

  • iPhone - UITableViewController not loading table

    - by RyanJM
    I'm pushing a UITableViewController onto a navigationController. The title (set in the viewDidLoad) shows up but not the table. numberOfSectionsInTableView is called. But tableView:numberOfRowsInSection: is not called. I'm passing in 1 so it should be looking for number of rows. - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } I'm setting up the view in the following manner: SelectUserViewController *nextController = [[SelectUserViewController alloc] initWithStyle:UITableViewStyleGrouped]; nextController.managedObjectContext = managedObjectContext; OrangeQCAppDelegate *delegate = [[UIApplication sharedApplication] delegate]; [delegate.navigationController pushViewController:nextController animated:YES]; Again, the viewDidLoad method is called. And my class is set up as follows: @interface SelectUserViewController : UITableViewController <UITableViewDelegate, UITableViewDataSource> {...} What else should I be looking at? When I go through the debugger, after it looks at numberOfSectionsInTableView it just disappears (I think it is in the UITableViewController class) and never comes back.

  • Why doesn't the undo/redo panel appear when I start a shake gesture in iPhone Simulator?

    - by dontWatchMyProfile
    I've created an NSUndoManager for the Managed Object Context of Core Data, like this: NSUndoManager *undoManager = [[NSUndoManager alloc] init]; [undoManager setLevelsOfUndo:10]; [managedObjectContext setUndoManager:undoManager]; [undoManager release]; In the app delegate where the didFinishLaunching method is called, I did this: application.applicationSupportsShakeToEdit = YES; For some reason, I never get that undo/redo panel when I make a shake gesture in iPhone Simulator (from the menu). Must I enable undo/redo somewhere else, maybe in the Info.plist file?

  • Gathering mac addresses with Python

    - by William
    Hi, is there a good way to gather the mac addresses of machines on a local network using Python. If it helps I'm trying to execute this python script from the DHCP server for the network. I'm new to Python but would it be a bad idea to look at the DHCP leases file for this info? I'd like to use this inside a Django app eventually. Thanks.

  • Memory leak when declaring NSString from ABRecordCopyValue

    - by Ben Thompson
    I am using the following line of code... NSString *clientFirstName = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty); The 'analyse' feature on Xcode is saying that this giving rise to a potential memory leak. I am not releasing clientFirstName at all as I have neither alloc or retain'd it. However, I am conscious that ABRecordCopyValue may not be returning an object as say a command like [NSMutableArray arrayWithArray:someArray] would which might mean I am indeed creating a new object that I control and must release. Keen to hear thoughts...

  • Which type of design pattern should be used to create an emulator?

    - by Facon
    I have programmed an emulator, but I have some doubts about how to organizate it properly, because, I see that it has some problems about classes connection (CPU <- Machine Board). For example: I/O ports, interruptions, communication between two or more CPU, etc. I need for the emulator to has the best performance and good understanding of the code. PD: Sorry for my bad English. EDITED: Asking for multiple patterns.

  • iOS - playing a youtube video from a webview thumbnail

    - by soleil
    Was about to finally submit an app when I realized that the youtube videos I'm playing play from the iPhone, but not the iPad. Here's the code I'm using: NSString *embedHTML = @"\ <html><head>\ <style type=\"text/css\">\ body {\ background-color: transparent;\ color: white;\ }\ </style>\ </head><body style=\"margin:0\">\ <embed id=\"yt\" src=\"%@\" type=\"application/x-shockwave-flash\" \ width=\"%0.0f\" height=\"%0.0f\"></embed>\ </body></html>"; NSString *html = [NSString stringWithFormat:embedHTML, [videoItem objectForKey:@"URL"], thumb.frame.size.width, thumb.frame.size.height]; UIWebView *videoView = [[UIWebView alloc] initWithFrame:thumb.frame]; [videoView loadHTMLString:html baseURL:nil]; [videoContainer addSubview:videoView]; Is there any reason this would work on the iPhone and not the iPad? I'm testing on a 1st generation iPad. The videos play on both iPhone models I've tested (3GS and 4S). Nothing happens at all when I tap on the webviews on the iPad.

  • XCode, error: '_object' undeclared. Need some help solving this problem

    - by user309030
    I've got this code in my viewController.m file - (void)viewDidLoad { [super viewDidLoad]; GameLogic *_game = [[GameLogic alloc] init]; [_game initGame]; ....... } GameLogic is another class which I created. in the same viewController.m file, I have got another function - (void)test { if([_game returnElecFence]) { NSLog(@"YES"); } else { NSLog(@"NO"); } } Problem is, whenever the test function is called, I get an error saying '_game' undeclared. I tried putting the GameLogic init code in the .h file and on top of the @implementation to make it global but every method I tried resulted in a worse error. TIA to anyone who can suggest some ideas to clear this error up

  • press button to open web page from app

    - by Lee
    I have an app that I want to interact with a web page. Basically I want to press a button and the web page will open in a new view... Sorry I wasn't clear, I am developing on a Mac for an iPhone. Currently I have a "locate me" app that displays your Latitude and Longitude. I want to use those variables to populate 2 of the blanks on a PHP web page/form I have developed. I have added a label and button to my current app, when the button is pressed the URL with the Lat and Long (as passed vars) are displayed in the label. I want those vars to appear on my web page. Hope this is clearer... Solved: I just added these lines of code I found here: NSURL *url = [ [ NSURL alloc ] initWithString: @"http://www.cnn.com" ]; [[UIApplication sharedApplication] openURL:url];

  • Using (void)awakeFromNib

    - by MN
    I am trying to run an action when the application starts. The action checkAtStart is supposed to display an alert if there is no text in field1 and hide startView if there is text in field1. checkAtStart works fine if assigned to a button, but when I try to run it using (void)awakeFromNib, the alert will display no matter what and startView will never hide. Its probably something really simple that I'm forgetting. Any help is appreciated! Here is my code: - (void)awakeFromNib { [self checkAtStart:self]; } - (IBAction)checkAtStart:(id)sender { if (field1.text == nil || [field1.text isEqualToString:@""]) { NSString *msg = nil; msg = nil; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Test Message" message:@"Test Message" delegate:self cancelButtonTitle:@"Close" otherButtonTitles: nil]; [alert show]; [alert release]; [msg release]; } else { startView.hidden = YES; } }

  • iPhone: Using a Singleton with Tabview Controller and Navigation Controller

    - by malleswar
    Hi Friends, I have developed a small iPhone application by using singleton that I use to navigate through the views. Here is a sample method from my singleton class. + (void) loadMenuController:(NSMutableArray *)menuItems{ MenuViewController *menuViewControler = [[MenuViewController alloc] initWithNibName:@"MenuViewController" bundle:nil]; [menuViewControler setMenuItems:menuItems]; RootViewController *root = ( P2MAppDelegate *appDelegate = (P2MAppDelegate*) [[UIApplication sharedApplication] delegate]; UINavigationController *navController = [appDelegate navigationController]; [navController pushViewController:menuViewControler animated:YES]; [menuViewControler release]; } Now my requirement has changed to require a tab view controller . I could change my application delegate to a tabview controller but I still need to navigate inside each tab. I am unable get a clue how to navigate from my singleton class. Please guide me. Please let me know if my query is not clear. Thanks in advance. Regards, Malleswar

  • Defined outlets, connected them, everything looks fine, nothing works.

    - by Tom
    Hi! I'm trying to play with a WebView. I made an outlet: IBOutlet UIWebView *browser; Defined it as a property: @property (nonatomic, retain) IBOutlet UIWebView *browser; Synthethized it: @synthesize browser; Finally, I connected it in Interface Builder, really it is. Then I try to do something with it i.e.: [browser loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://apple.com"]]]; Or also: Etape *etape = [[Etape alloc] init]; NSString *html = [etape generateHTMLforEtape:[current_etape objectAtIndex:0]]; [browser loadHTMLString:html baseURL:nil]; [etape release]; I get no errors, I tried to Build & Analyse, no notices or warnings or errors.. I've been searching for one whole day, please help me :/ Thanks a lot! EDIT: Here's screenshots of my connections for my WebView:

  • Refactor custom wizard to reduce flicker

    - by Matthew Brown
    I have implemented a custom wizard control in C# windows forms by creating a base form which has the shared components and then making child forms for each step of the process. I then have a class which hides/shows the child forms when you move from one step to another. The problem is that flickering is bad when moving between forms. Does anyone know a way to either keep this method and reduce the flicker or refactor it to make it use a single form (which should definitely reduce the flicker)?

  • Store an array of UIViews in NSUserDefaults

    - by Mona
    I'm trying to add an array of uiviews to NSDefault but it doesn't seem to be keep the array. Does any one know why? I also tried to store each view in nsvalue before storing it in nsdefault which still didn't work. NSArray *arr = [[NSArray alloc] initWithObjects:[NSValue valueWithNonretainedObject:myView], nil]]; NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; [defaults setObject:arr forKey:@"myKey"]; NSArray *resultArray = [defaults objectForKey:@"myKey"]; and resultArray is nil! Thanks the reason why I'm trying to do this is because these are the header views of my uitableview. Since it takes time to create them I wanted to create them only once and store them for future access.

  • Will Visual Studio 2010 democratize UML ?

    - by asksuperuser
    I've been very upset these past years with all the UML tools (especially the clunky mammoth Rational Rose from IBM which I really hated each time a client asked to use it). I think UML did suffer from bad integration. I rarely used UML myself because of lack of productivity. So I had a positive surprise with Visual Studio 2010 especially the sequence diagram reversing tool which really helps understand code. For people who had tried VS 2010 Ultimate do you think the same ?

  • Adding image to navigation bar

    - by 4thSpace
    I'd like an image to take up all of a navigation bar. This is the navigation that comes with a navigation based app. It appears on the RootViewController with the accompanying UITableView. I've seen some examples of how this might work. Set navigation bar title: UIImage *image = [UIImage imageNamed:@"TableviewCellLightBlue.png"]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; [self.navigationController.navigationBar.topItem setTitleView:imageView]; The problem there is it only covers the title rather than the entire navigation bar. There is also this thread: http://discussions.apple.com/message.jspa?messageID=9254241#9254241. Towards the end, the solution looks to use a tab bar, which I'm not using. It is that complicated to set a navigation bar background? Is there some other simpler technique? I'd like to have a background for the navigation and still be able to use title text.
