Accelerate.framework 由 C 函数组成，所以:

The Accelerate.framework consists of C functions, so:

vImage_Error vImagePermuteChannels_ARGB8888(    const vImage_Buffer *src,
                                                const vImage_Buffer *dest,
                                                const uint8_t       permuteMap[4],
                                                vImage_Flags        flags )     VIMAGE_NON_NULL(1,2,3)  __OSX_AVAILABLE_STARTING( __MAC_10_4, __IPHONE_5_0 );

可以通过以下方式使用:

Can be used via:

[DllImport("/System/Library/Frameworks/Accelerate.framework/Frameworks/vImage.framework/vImage")]
public unsafe static extern vImageError vImagePermuteChannels_ARGB8888(ref vImageBuffer src, ref vImageBuffer dest, [MarshalAs(UnmanagedType.LPArray)]uint[] permuteMap, vImageFlags flags);
