  • UIViewController rotate methods

    - by Corey Floyd
    What object is responsible for dipatching the UIViewController rotation method calls, i.e: – shouldAutorotateToInterfaceOrientation: – willRotateToInterfaceOrientation:duration: – willAnimateFirstHalfOfRotationToInterfaceOrientation:duration: – willAnimateSecondHalfOfRotationFromInterfaceOrientation:duration: – didRotateFromInterfaceOrientation: I imagine it is UIApplication (but maybe the AppDelegate or UIWindow). The next question, is how does the object know which UIViewController to talk to? How does it know which UIViewController has its view as the subview of the window? Is there a message you can send or a property you can set (of some object) that sets the "Active" UIViewController for the app?

  • iPad app store visibility

    - by Jameson
    So I created my iPad app and submitted it to the store, the app is called photogoo. I now have the iPad and I am finding that it is not possible to browse to the app in any way, confirmed by the zero downloads from yesterday. It is only possible to find by searching.. I also noticed that the apps in entertainment were being listed alphabetically and stopped at "F" Am I really being excluded because my app starts with the letter "P" or is it possible there is some reason that I am not being listed under "all apps"?

  • How do I access variable values from one view controller in another?

    - by Thomas
    Hello all, I have an integer variable (time) in one view controller whose value I need in another view controller. Here's the code: MediaMeterViewController // TRP - On Touch Down event, start the timer -(IBAction) startTimer { time = 0; // TRP - Start a timer timer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(updateTimer) userInfo:nil repeats:YES]; [timer retain]; // TRP - Retain timer so it is not accidentally deallocated } // TRP - Method to update the timer display -(void)updateTimer { time++; // NSLog(@"Seconds: %i ", time); if (NUM_SECONDS == time) [timer invalidate]; } // TRP - On Touch Up Inside event, stop the timer, decide stress level, display results -(IBAction) btn_MediaMeterResults { [timer invalidate]; NSLog(@"Seconds: %i ", time); ResultsViewController *resultsView = [[ResultsViewController alloc] initWithNibName:@"ResultsViewController" bundle:nil]; [self.view addSubview:resultsView.view]; } And in ResultsViewController, I want to process time based on its value ResultsViewController - (void)viewDidLoad { if(time < 3) {// Do something} else if ((time > 3) && (time < 6)) {// Do something else} //etc... [super viewDidLoad]; } I'm kind of unclear on when @property and @synthesize is necessary. Is that the case in this situation? Any help would be greatly appreciated. Thanks! Thomas

  • Why not use development provisioning instead of ad hoc?

    - by lawrence
    I was under the impression that when you use a development provisioning profile for a build of an app, only the specified developers can deploy that build to a phone. But I just deployed a build that uses a development profile to a phone using Xcode Organizer, even though I'm not one of the valid developers for that profile. One of my colleagues, also not a valid developer, did the same with his phone using iTunes. In that case, why not use a development provisioning profile for distributing your app to e.g. your QA team, instead of ad hoc distribution?

    - by John Smith
    Hello I am having trouble compiling a static library for the iPhone. It worked in the past. It keeps saying "target specifies 'com.apple.product-type.tool' but there is no such product for the 'iphoneos' platform. I have rechecked the static compilation flag.

  • UISlider returns two Touch Up Inside events, why does that happen?

    - by willc2
    I have a slider that I'm using to set a float value somewhere. I connect Value Changed to a method in my viewController. That part works fine. I need to know when the user starts touching the control but not necessarily every single instant that the slider changes (I receive the Value Changed events for that). So I connected a Touch Up Inside event to another method in the viewController. The problem it, that method gets called twice when the user touches the UISlider control. WTF? It doesn't work that way with UIButtons or other touch events like Touch Down. I can work around it, I think, but it seems like a bug in the way the slider control handles touches. Does anybody know why it happens? BTW: the double touch event happens even when Touch Up Inside is the only connected event.

  • NSFetchedResultsController titleForHeaderInSection with formatted NSDate

    - by Daniel Granger
    In my Core Data app I am using a FetchedResultsController. Usually to set titles for headers in a UITableView you would implement the following method like so: - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { id <NSFetchedResultsSectionInfo> sectionInfo = [[<#Fetched results controller#> sections] objectAtIndex:section]; return [sectionInfo name]; } where [sectionInfo name] returns a NSString. my sectionKeyPath is based on an NSDate and this all works fine apart from the section headers it gives me are the raw date description strings (e.g. 12/12/2009 12:32:32 +0100) which look a bit of a mess in a header! So I want to use a date formatter on this to make a nice header like "Apr 17 2010" but I can't do that with the [sectionInfo name] as this is NSString! Any Ideas? Many Thanks

  • Replacing a calloutaccessoryview in mkannotationview

    - by Mugunth Kumar
    In my viewForAnnotation delegate, I create a MKAnnotationView with leftCalloutaccessory as a info button. When the info button is tapped, I want to replace it with a UIActivityIndicator. So in the calloutAccessoryTapped delegate, I wrote view.leftCalloutaccessoryView = [UIActivityIndicator indicatorWithStyle:UIActivityIndicatorWhite]; The callout accessory seems to change, but it seems like the view doesn't get updated immediately. That's when the callout accessory gets hidden (by tapping another pin) and is re-opened, I see a spinner. But otherwise, I don't. I tried calling [view setNeedsdisplay] and [view setNeedsLayout] and [view layoutsubviews] as well but in vain. Any suggestions/pointers?

  • How do I display a local html file in a UIWebView?

    - by Thomas
    I have a relatively simple question that I cannot seem to find the answer for. While doing the Google Maps Java API Tutorials, I ran into a problem. I can load an HTML file from the web, but when I try it locally, it just displays the contents of the file instead of running the script. Here's what works: NSString *url = @"http://code.google.com/apis/maps/documentation/v3/examples/geocoding-simple.html"; NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:url]]; [webView loadRequest:request]; I want to store the HTML file locally and run it from the device itself, so I tried: [webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"geocoding-simple" ofType:@"html"]isDirectory:NO]]]; and it just displayed the contents of the file. What am I doing wrong here? Thomas
