阅读更多关于 UIImagePickerController Overlay Buttons Not Firing

问题 I have a UIImagePickerController of type camera when the user lands on a page. I have put a custom camera overlay on top of the UIImagePickerController, but none of the button events are firing.

问题 I'm having trouble with using a UIImagePickerController. Basically, though the picker is being displayed fine, the UIImagePickerController didFinishPickingMediaWithInfo method is refusing to be called (I've tried NSLogging all the way through, it just doesn't get called). Here's my code (I've defined imgPicker in the header as an UIImagePickerController): -(IBAction)grabImage { self.imgPicker = [[UIImagePickerController alloc] init]; self.imgPicker.allowsImageEditing = YES; self.imgPicker

iOS SDK - How to get the status bar back when using UIImagePickerController?

阅读更多关于 iOS SDK - How to get the status bar back when using UIImagePickerController?

As soon as I add a UIImagePickerController sub view to my view the status bar disappears and I can't get it back. Is there any way to keep the status bar visible? UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera; [self.view addSubview:imagePicker.view]; [imagePicker viewWillAppear:YES]; [imagePicker viewDidAppear:YES]; [[UIApplication sharedApplication] setStatusBarHidden:NO animated:NO]; I had to do the same thing in a camera app as well. Apparently, in addition to setting the status bar to not be

I have an app that lets the user take a picture with his/her iPhone and use it as a background image for the app. I use UIImagePickerController to let the user take a picture and set the background UIImageView image to the returned UIImage object.

how to change the UIImagePickerController crop frame

阅读更多关于 how to change the UIImagePickerController crop frame

when opening working with an UIImagePickerController and setting allowsImageEditing = YES; there is a default cropping frame that is 320x320. In my case, I would like to setup that cropping frame to 320x240 for images that are landscape, and 240x320 for images that are portrait. However, I haven't been able to find a way to change that 320x320 frame that is used when editing /cropping a photo. Has any of you found a way to do it? Thanks! You have to implement it your self. The picker only performs 320x320 cropping. So instead set allowsImageEditing = NO; Now you will get the full image back.

UIImagePickerController: Detecting Camera button (shutter) pressed

阅读更多关于 UIImagePickerController: Detecting Camera button (shutter) pressed

问题 I would like to call a method that takes an NSNotification immediately after the user presses the camera shutter (i.e when the "Preview" tab bar has the buttons "Retake" and "Use"). I can't use the didFinishPickingImage method because at this time the user has already pressed the "Use" button. I have already implemented this by cameraOverlayView property of UIImagePickerController(see comments), but I wonder whether there are quicker ways of 'observing' this action. Any ideas? 回答1: To learn

iPad iOS7 - UIImagePickerController in UIPopoverController has wrong preview image

阅读更多关于 iPad iOS7 - UIImagePickerController in UIPopoverController has wrong preview image

I am using an UIImagePickerController within an UIPopoverController which is working perfectly with iOS6. With iOS 7 the "preview" image which is shown to capture the image is rotated, but if I take a picture it is saved correctly. This is how I get my picker: UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; imagePicker.delegate = self; imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera; imagePicker.mediaTypes = [NSArray arrayWithObjects: (NSString *) kUTTypeImage, nil]; imagePicker.allowsEditing = NO; And add it to a popover controller: self
