uipopovercontroller

问题 I am trying to display MxxDialogViewController from a popover and am getting an exception 18.35 Request is null - assuming this is a TabBar type situation where ViewDidLoad is called during construction... patching the request now - but watch out for problems with virtual calls during construction while calling base.ViewDidLoad() here is what I did to demonstrate the problem as a small sample: I took N-23 example and added to the first section a new element with the Tapped command new

问题 I'm working on an app that is supposed to be universal, one app for both iPad and iPhone. I would like to keep their interfaces as similar as possible. In the iPhone app I am using a Tab bar controller, and one of those tabs goes to an image picker controller. Obviously I cannot do that in iPad. So I have hijacked control of that button to bring a popupcontroller that has the image picker in it. This all works well enough, except when I bring up the popup, it is not in the correct place. When

问题 I am using ARC on an iPad app with the code below, the popover flashes on the screen, but doesn't stay. What I am doing wrong? Please help - (IBAction)photoLibraryAction:(id)sender { UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; [imagePicker setDelegate:self]; UIPopoverController *pop1 = [[UIPopoverController alloc] initWithContentViewController:imagePicker]; [pop1 setDelegate:self]; [pop1 presentPopoverFromBarButtonItem:sender permittedArrowDirections

问题 I need help figuring this crash out. I checked stackoverflow for answers, but non of the answers relates to my situation. This is my code. - (void)addImagesActionSheetClickedButtonAtIndex:(NSInteger)buttonIndex { // Cancel if (buttonIndex == 2) return; //Take picture if (buttonIndex == 0) { //Take picture isFromLibrary = NO; [self.imagePicker setSourceType:UIImagePickerControllerSourceTypeCamera]; [self.navigationController presentViewController:self.imagePicker animated:YES completion:NULL];

问题 Does anyone know of how I would go about creating a UIPopoverController like the one found in Tweetbot form Tapbots? For months I have been trying to figure this out and gave up thinking it wasn't possible. When Tweetbot received an update with this, it made realize it is possible but I still can't seem to figure it out. Does anyone know of classes I could download that has an identical UIPopover? Thanks Edit: http://d.pr/LPI9 回答1: Popover controllers are for use exclusively on iPad devices.

问题 I am writing an iPad app and am very new to objective C. I am currently trying to use a popover as a menu within a view controller. I understand how to set the popup up and have a tableview in it for a user to select an item from. However, I am not sure how to then pass the information back to the container view which holds the popover. didSelectRowAtIndexPath will be called within the UITableViewController which is presumably inside the popover view controller. Can anyone point me in the

问题 Is it possible inside Xcode to add a button inside a popover that will take the user to a new view? 回答1: Yes. [myPopOver.contentViewController.view addSubview:myButton]; [myButton addTarget:self action:@selector(goToNextView) forControlEvents:UIControlEventTouchUpInside]; - (void)goToNextView { //if you are using xibs use this line UIViewController *controller = [[UIViewController alloc] initWithNibName:@"myXib" bundle:[NSBundle mainBundle]]; //if you are using storyboards use this line

问题 I have a view with a bunch of button in a UIScrollView . When the user presses a button, I want a UIPopOverController to display pointing at the selected button. It kind of works, but the popover is the wrong size and points to a random point in the view. Here is my code. -(void)detail:(id)sender{ UIButton *button = sender; NSLog(@"tag = %i", button.tag); UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController]; if (UI_USER_INTERFACE
