iOS-AVCapture,自定义相机功能

AVCaptureDevice主要用来获取iPhone一些关于相机设备的相关属性。

必须引用一个AVFoundation框架：

//#import

1.前置和后置摄像头

typedef NS_ENUM(NSInteger, AVCaptureDevicePosition) {

AVCaptureDevicePositionUnspecified = 0,

AVCaptureDevicePositionBack = 1,

AVCaptureDevicePositionFront = 2

} NS_AVAILABLE(10_7, 4_0);

2.闪光灯开关

typedef NS_ENUM(NSInteger, AVCaptureFlashMode) {

AVCaptureFlashModeOff = 0,

AVCaptureFlashModeOn = 1,

AVCaptureFlashModeAuto = 2

} NS_AVAILABLE(10_7, 4_0);

3.手电筒开关--其实就是相机的闪光灯

typedef NS_ENUM(NSInteger, AVCaptureTorchMode) {

AVCaptureTorchModeOff = 0,

AVCaptureTorchModeOn = 1,

AVCaptureTorchModeAuto = 2,

} NS_AVAILABLE(10_7, 4_0);

4.焦距模式调整

typedef NS_ENUM(NSInteger, AVCaptureFocusMode) {

AVCaptureFocusModeLocked = 0,

AVCaptureFocusModeAutoFocus = 1,

AVCaptureFocusModeContinuousAutoFocus = 2,

} NS_AVAILABLE(10_7, 4_0);

5.曝光量调节

typedef NS_ENUM(NSInteger, AVCaptureExposureMode) {

AVCaptureExposureModeLocked = 0,

AVCaptureExposureModeAutoExpose = 1,

AVCaptureExposureModeContinuousAutoExposure = 2,

AVCaptureExposureModeCustom NS_ENUM_AVAILABLE_IOS(8_0) = 3,

} NS_AVAILABLE(10_7, 4_0);

6.白平衡

typedef NS_ENUM(NSInteger, AVCaptureWhiteBalanceMode) {

AVCaptureWhiteBalanceModeLocked = 0,

AVCaptureWhiteBalanceModeAutoWhiteBalance = 1,

AVCaptureWhiteBalanceModeContinuousAutoWhiteBalance = 2,

} NS_AVAILABLE(10_7, 4_0);

7.距离调整

typedef NS_ENUM(NSInteger, AVCaptureAutoFocusRangeRestriction) {

AVCaptureAutoFocusRangeRestrictionNone = 0,

AVCaptureAutoFocusRangeRestrictionNear = 1,

AVCaptureAutoFocusRangeRestrictionFar = 2,

} NS_AVAILABLE_IOS(7_0);

写了个小Demo, 实现了自定义摄像头, 拍照, 翻转镜头, 闪光灯等功能, 如有需要Demo下载地址如下:
