iPhone定制相机叠加（加图像处理）：操作方法 [英] iPhone custom camera overlay (plus image processing) : how-to

问题描述

可能重复：

今天从App Store购买的许多图片共享应用使用自定义相机，而不是由苹果提供的标准相机选择器。

Many image sharing apps available today from the App Store use a custom camera instead of the standard camera picker provided by Apple.

有没有人知道任何有关创建自定义摄像头的教程或提示？

Does anyone know any tutorials or tips for creating a custom camera?

推荐答案

是，从代码中创建UIImagePickerController，调整其属性，在其上添加覆盖，并与您的控制器，控制任何你想要的覆盖：自定义控件，覆盖图像等...

Yes, create a UIImagePickerController from code, adjust its properties, add an overlay onto it, and with you controller, control whatever you want on that overlay : custom controls, overlaying images, etc...

像这样：

self.picker = [[UIImagePickerController alloc] init];
self.picker.sourceType = UIImagePickerControllerSourceTypeCamera;
self.picker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;
self.picker.cameraDevice = UIImagePickerControllerCameraDeviceRear;
self.picker.showsCameraControls = NO;
self.picker.navigationBarHidden = YES;
self.picker.toolbarHidden = YES;
self.picker.wantsFullScreenLayout = YES;

// Insert the overlay
self.overlay = [[OverlayViewController alloc] initWithNibName:@"Overlay" bundle:nil];
self.overlay.pickerReference = self.picker;
self.picker.cameraOverlayView = self.overlay.view;
self.picker.delegate = self.overlay;

[self presentModalViewController:self.picker animated:NO];

OverlayViewController 是您必须编写的控制器

OverlayViewController is the controller that you must write to control everything you add onto the overlay.

pickerReference 是您可以保留以向相机发送订单的财产。例如，您可以从来自放置在叠加层上的UIButton的IBAction调用以下内容：

pickerReference is a property you can keep to send orders to the camera. For example, you could call the following from an IBAction coming from a UIButton placed onto the overlay :

[self.pickerReference takePicture];
