  • iPad: CFBundleDocumentTypes & UIFileSharingEnabled issues

    - by carloe
    Has anyone gotten UIFileSharingEnabled or CFBundleDocumentTypes to work? I added UIFileSharingEnabled as true to my plist and used Apple's example from the link below for CFBundleDocumentTypes, but can't seem to get it to work. I don't see my app under file sharing in iTunes, and I do not get the option to open documents I registered in my app when I click on them in the mail.app http://developer.apple.com/iphone/library/documentation/General/Conceptual/iPadProgrammingGuide/CoreApplication/CoreApplication.html

  • Create Audio file on iPhone/iPad from many other audio files (mixer)

    - by Brian
    I am trying to create something similar like Piano app on the iPhone. When people tap a key, it play a piano note. Basically, there will have only 7 notes (C) at the moment. Each note is a .caf file and its length is 5 seconds. I do not know if there is any way to save the song user played and export to mp3/caf format? The AVAudioRecord seems only record from the microphone input. Many thanks

  • UISplitView: how to access instance?

    - by chpwn
    I have a navigation controller in my left portion of my split view, and in the right portion. But sometimes, for example when an item is tapped, my left side must manually set the view controller on the right side. Where is the best place to store the split view controller instance? Pass it around to each view controller on the left side, like I do with the navigation controller? Store it in my App Delegate and then access it via a property with [[UIApplication sharedApplication] delegate].splitView?

  • UIWebView rotation and memory problem

    - by Fer
    Hi. I have an UIWebView that loads a embedded XHTML like this: body = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)]; body.scalesPageToFit = YES; body.backgroundColor = [UIColor scrollViewTexturedBackgroundColor]; body.autoresizingMask = UIViewAutoresizingFlexibleBottomMargin | UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin; [self.view addSubview:body]; [body loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"article16" ofType:@"xhtml"]isDirectory:NO]]]; This XHTML have a lot of images, and when I rotate the device I got some memory warnings, and sometimes the app crashes. If I remove the autoresizing mask, specifically the UIViewAutoresizingFlexibleWidth (I have tryed with only UIViewAutoresizingFlexibleLeftMargin and UIViewAutoresizingFlexibleRightMargin with no problems), the memory warning stops, and the app does not crash anymore. If I remove all autoresizing mask, and set the new webView frame in didRotate or willRotate, I got the same warnings as using the UIViewAutoresizingFlexibleWidth. There's a app, called Atomic Web that could open the same XHTML and rotate with no memory warnings, and safari can open it as well, but if I create a project with only that UIWebView, the app sometimes crashes. Someone knows what this may be? Can I set the webview frame in other way? Why can't I use the autoresizing mask? Thanks for your attention.

  • UIModalPresentationFormSheet and MPMoviePlayer on iPhone/iPad OS 3.2?

    - by user325699
    I have a UIModalPresentationFormSheet which has a movie player inside of it. When the user hits the button to play it in full screen, my UIModalPresentationFormSheet is still there ontop of the video while it's playing in full screen, behind the window and behind the shadow. What do I need to do to get rid of the dim so the video is playing in fullscreen with being able to select buttons and not having an annoying dim ontop of it?

  • Dismissing iPad UIPopoverController from within it's content controller

    - by joshholat
    So I have a popover with a button in it. When that button is pushed, I want the popover to go away. It seems easy enough, but I can't figure it out for the life of me. The code I use to show the popover is below: AddCategoryViewController* content = [[AddCategoryViewController alloc] init]; UIPopoverController* aPopover = [[UIPopoverController alloc] initWithContentViewController:content]; aPopover.delegate = self; [content release]; // Store the popover in a custom property for later use. self.addCategoryPopover = aPopover; [aPopover release]; [addCategoryPopover presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES]; Within the addcategoryviewcontroller, I have: -(IBAction)saveAddCategory:(id)sender { if (rootViewController == nil) rootViewController = [[RootViewController alloc] init]; [rootViewController.addCategoryPopover dismissPopoverAnimated:YES]; [rootViewController dismissPopover]; } Rootviewcontroller is where the popover is being created from. Unfortunately, neither of those methods work to dismiss it. any help?

  • ipad SplitView Orientation in DetailView

    - by nishantcm
    I am using this code in the DetailView.m of a splitview app. Now the orientation changes occur only when the device is rotated. The detection does not take place when the app is launched. I also get this warning warning: 'RootViewController' may not respond to '-adjustViewsForOrientation:' What change do I need to make the app adjust the orientation code when the app is launched. (void) willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration { [self adjustViewsForOrientation:toInterfaceOrientation]; } (void) adjustViewsForOrientation:(UIInterfaceOrientation)orientation { if (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight) { detailDescriptionLabel.center = CGPointMake(235.0f, 42.0f); bigthumbImageView.center = CGPointMake(355.0f, 70.0f); } else if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown) { detailDescriptionLabel.center = CGPointMake(160.0f, 52.0f); bigthumbImageView.center = CGPointMake(275.0f, 80.0f); } }

  • UIModalTransitionStylePartialCurl not rotating

    - by Mongo
    I've got a modal view controller that is being displayed using UIModalPresentationFullScreen with the TransitionStyle set as UIModalTransitionStylePartialCurl. This works beautifully. My problem is that when the device is rotated, my view rotates (as intended), but the "curl" effect does not. Does anyone know if this is by design, or is there something else that needs to be done? Thanks.

  • How to set the title of UIToolBar?

    - by Kelvin
    How can I set the title of UIToolBar such that it looks the same as the title in UINavigationBar? I tried to use a button with plain style, it looks ok, but it will be highlighted when I click on it... Is there any better way to set the title in the detail view of split view?

  • Removing Divider Line from UISplitViewController

    - by tilomitra
    Guys, I know a similar question exists but the thread seems to be inactive, and I really would like this question to be answered. It's been annoying me for a few days now. I'm wondering how to remove the divider line between the Master and Detail view in the UISplitViewController. I know its possible to remove/hide/cover it up because I see some apps in the store without that line. I have tried setting backgroundColor to clearColour on my views but to no avail. So SO community, you're my only hope!

  • How do I create a UISplitView manually?

    - by Mark
    I have an app that is going to navigate to a UISplitView (inside another view altogether) like so: - (void) switchToMyDayView { NSLog(@"Show My Day Screen"); if (self.myDayController.view.superview == nil) { if (self.myDayController == nil) { MyDayController *myController = [[MyDayController alloc] initWithNibName:@"MyDay" bundle:nil]; self.myDayController = myController; [myController release]; } [homeScreenController.view removeFromSuperview]; [self.view insertSubview:self.myDayController.view atIndex:0]; } } Which is done on the main navigation screen Now, the MyDayController has a XIB called MyDay.xib which has these items: File's Owner: MyDayController First Responder: UIResponder Split View Controller ---->Navigation Controller ---->Navigation Bar ----> Table View Controller ----> Navigation Item ---->View Controller So, I need some more components here, I need a UITableViewController and a UISplitViewControllerDelegate correct? I was going to just implement these protocols in my MyDayController, is this sort of standard? So, after the code above, I get an error: -[UIViewController _loadViewFromNibNamed:bundle:] loaded the "MyDay" nib but the view outlet was not set. so, how can I fix it using the UISplitViewController? I know that the UISplitViewController has a view property, but I cannot use it/connect it up in IB can I? Thanks a lot Mark

  • UIRotationGestureRecognizer minimum rotation value

    - by dc
    Is it possible to set a minimum rotation value necessary for a UIRotationGestureRecognizer to transition into UIGestureRecognizerStateRecognized? I'm using multiple recognizers, and my UIRotationGestureRecognizer keeps getting called with a very small rotation (Between 1 and 15 degrees either direction) rather than my UIPinchGestureRecognizer. What I'd like to do is only have the rotation be called if the rotation is within a certain range, otherwise cancel it and let the pinch be called.

  • Toolbar hiding on rotated UISplitView DetailView

    - by Gerry
    I've based my app on Apple's SplitView project type. I have a TableView as the Master, and am using different types of views as the Detail view. To select types of detail view, I'm using the fancy concept of buttons on my DetailView toolbar. When the DetailView is derived from UIViewController, everything is good. When the DetailView derives from UIViewController, but contains a UITableView then I have problems. In portrait view the toolbar is visible. In landscape mode the toolbar is hidden, even though the Tableview is moved down to allow space for it. The UIToolbar and UITableView are both defined in my NIB file which is loaded to create the detail view. Why is my toolbar invisible in landscape? BTW, is this the best way to choose Detail view types with UISplitView? Bonus question, what if selecting a row in my DetailView tableview should bring up another View, I can't push it like I would with a NaviagtionController, so how do I go back to the detail tableview? Thanks, Gerry

  • UIAlertController handle dismiss upon click outside (IPad)

    - by Tomer Peled
    Previous to iOS8 we used the UIActionSheet for showing alert and now we need to use the UIAlertController. When we used the UIActionSheet we could easily handle situations where the user clicked outside the pop up (which means he want to cancel the operation) by comparing the clickedButtonAtIndex to the cancelButtonIndex - if the user indeed pressed outside the popup we got the cancel button index in this function. How can we handle these situations with the new UIAlertController? I tried to use the "completion" block but it doesn't have any context. Is there an easy way to handle this? (other than "saving" the actions states in some general variable).

  • iPad popover - resignFirstResponder issue

    - by mosdev
    I have two text fields email and password. The following code works fine when the fields are presented on a regular view but when they are on a popover, the resignFirstResponder does not work (becomeFirstResponder works). textFieldsShouldReturn was called for both fields. Any idea if I am missing something? Thanks! - (BOOL)textFieldShouldReturn:(UITextField *)theTextField { if (theTextField == email) { [password becomeFirstResponder]; return NO; } [theTextField resignFirstResponder]; return NO; }

  • iPad UIColor Saturation Issues

    - by Carter Allen
    I am trying to draw a UIColor on the screen of a view-based app, and I am trying to do so using HSB. It is absolutely necessary for me to use HSB in this case. I can create a UIColor object with any S value from 0.0f to 0.75f, but past that the numerical changes have no effect on the actual saturation displayed. I need it to be 1.0f, but it is still using 0.75f. Any ideas on why it is doing that, and how I can make it work?

  • iPad App Cookies Storage?

    - by Aakburns
    Hi, I have an application that sends you to one website that shows a login form. I've read up on cookies from the apple reference (http://developer.apple.com/iphone/library/documentation/Cocoa/Reference/Foundation/Classes/NSHTTPCookie_Class/Reference/Reference.html#//apple_ref/occ/instm/NSHTTPCookie/initWithProperties:) I'm honestly just not understanding this at all. Can someone please explain how to get cookies working for an app? Post sample code? Thanks.

  • Solving iPhone/iPad out of memory issues

    - by Joonas Trussmann
    I have a strange issue where I'm scrolling through a paged UIScrollView which displays the pages of a PDF document (using Quartz 2D and CATiledLayer). When I page through memory allocation looks fine with it going up with a few initial pages and then keeping it steady as it obviously releases the memory kept for earlier pages. Upon hitting page x (not a certain PDF page or a certain number per se) memory usage goes from a couple of megs to 308 megs and the app crashes. So my question is: how to best try to find what's causing this? The object alloc tool in instruments shows the memory as simply going to malloc. (in huge chunks).
