问题 So i've been using UIImagepickercontroller to access the camera for photo and video capture, then i wanted to apply filters on those 2 sources, i succeeded with filtering token photos but i'am having trouble finding the solution for the rest, all i need is to access the raw image data : the live image feed that the camera is showing , apply the filter and then show the filtered ones instead. Any help or advice will be appreciated. 回答1: UIImagePickerController doesn't give you low level access

问题 I'm developing an iPhone app that records video. I create a UIImagePickerController, limit it to video recording then programatically ask the camera to startVideoCapture. Unfortunatly when I run the app I get the following in the console; "UIImagePickerController: ignoring request to start video capture; camera is not yet ready." Obviously the iPhone is not done setting things up. Is there a way that I can check the setup process has completed before starting to record? Many thanks in advance
