如何在IOS中完成操作后释放vImage缓冲区

// 导入vImage头文件
#import <Accelerate/Accelerate.h>

// 创建vImage缓冲区
vImage_Buffer buffer;
vImage_Error error;
vImage_CGImageFormat format = {
    .bitsPerComponent = 8,
    .bitsPerPixel = 32,
    .colorSpace = CGColorSpaceCreateDeviceRGB(),
    .bitmapInfo = kCGImageAlphaPremultipliedFirst | kCGBitmapByteOrder32Little,
    .version = 0,
    .decode = NULL,
    .renderingIntent = kCGRenderingIntentDefault
};
error = vImageBuffer_InitWithCGImage(&buffer, &format, NULL, imageRef, kvImageNoFlags);

// 执行操作
// ...

// 释放vImage缓冲区
vImageBuffer_Free(&buffer);
