uiimagepickercontroller

问题 Disclaimer : I realize this may not be approved by Apple, and I realize traversing the view hierarchy is programmatically unsafe. I'm trying to figure it out for my own curiosity :) I'd like to change the case of a UIImagePickerController's navigation bar items.

问题 update 2 viewDidAppear is executed twice, once before and once after, the overlay button is touched. Would a fix be to add a conditional to viewDidAppear which would return control to the calling class? If so, I would appreciated suggestions.

Can anyone help, please? - (void)viewDidAppear:(BOOL)animated { self

问题 I am building an app that allows users to add a timestamp to a photo. When a photo from the camera roll is selected my app sometimes crashes and Xcode displays the error: "Message from debugger: Terminated due to memory issue". I found it crashes if I try to add a timestamp to a very large image or if I repeatedly at a timestamp to the same image. Below is the code I believe is relevant to the issue.

问题 I'm writing an app that uses UIImagePickerController to let the user choose images from their library. On the iPad, it shows it in a popover (because you must) but the controller which is showing it is already in a popover, and you're not allowed to show a popover from another popover. I can't rework the whole app to avoid the files controller being in a popover, so what I'd like to do is to push the image picker onto the files controller's navigation stack. Obviously this isn't going to work

问题 I am trying to implement the imagepickercontroller inside a UITabBarController. So far, so good.... In my ViewController, where I initiate the imagePickerController and then place in my TabBarViewController tabbar array, I implemented the "loadview" method: - (void)loadView{ self.arController = [[IFAugmentRealityController alloc] initWithViewController:self]; [self showCamera]; [self initOverlayController]; self.picker.delegate = self; [self.view addSubview:self.picker.view]; } - (void

问题 I have an app designed for iPhone that makes use of the UIImagePickerController. The app run in landscape only up until the image picker comes into view in its default portrait. Problem 1: On the iPhone when I rotate the device to portrait to view the image library the image picker view seems to do a flip as if rotating from landscape to portrait?
