How to crop image after taken from UIImagePicker Camera?

由 荒凉一梦 提交于 2019-12-09 17:41:03
问题 I'm trying to allow the user to take 16x9 aspect ratio images to look like they are nice HD photos. I'm using the cameraViewOverlay to overlay black bars on both ends, but when the image is taken, how do I crop the top and bottom without resizing or changing the scale of the image? Thanks. 回答1: There are various posts around on how to scale/crop a UIImage you get back from the camera, like this one. It's a little trickier than you'd expect, because camera images are rotated, so you have to

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . I want to use photo picker view in customized form, such as showing a rectangle in screen to focus on specified area of the picture. However, UIImagePickerController can only offer a normal photo picker view. Is there any other class I can use to replace UIImagePickerController, or should I create a sub class of

How to prevent a modal UIImagePickerController from rotating?

由 删除回忆录丶 提交于 2019-12-09 05:30:38
问题 I have an app that fully support rotation. I am modally adding a UIImagePickerController for which there is no support for UIInterfaceOrientationLandscape and I cannot get the controller to stay in portrait. In other words, I need to disable rotation for the UIImagePickerController so it stays in portrait, without removing rotation for the rest of my app. this seems basic, but I can't seem to locate it. How can I prevent this rotation? UPDATE As suggested, I tried subclassing with the

Memory Troubles with UIImagePicker

由 给你一囗甜甜゛ 提交于 2019-12-09 00:18:08
问题 I'm building an app that has several different sections to it, all of which are pretty image-heavy. It ties in with my client's website and they're a "high-design" type outfit. One piece of the app is images uploaded from the camera or the library, and a tableview that shows a grid of thumbnails. Pretty reliably, when I'm dealing with the camera version of UIImagePickerControl, I get hit for low memory. If I bounce around that part of the app for a while, I occasionally and non-repeatably

UIImagePickerController AVAudioPlayer

由 末鹿安然 提交于 2019-12-08 20:33:28
问题 When I open a UIImagePickerController , I can display the device's camera input stream. But when I play an AVAudioPlayer with [player play] then the camera stops working. How can I deal with that? 回答1: you can't because UIIMagePickerController is controlling the audio, you will need to use low level AVFoundation in order to do that. checkout AVCam sample code how to record a movie and add the view as subview , that way you will stay in control of the audio and will be able to play audio. 来源：
