facebook - 如何使用社交库将 CGImageRef 分享到 facebook？

Question

这是具有图像数据的方法，该图像将比写入相机胶卷

CGImageRef cgImageResult = [self newSquareOverlayedImageForFeatures:features
                                                                                       inCGImage:srcImage 
                                                                                 withOrientation:curDeviceOrientation 
                                                                                                                 frontFacing:isUsingFrontFacingCamera];

                                  if (srcImage)
                            CFRelease(srcImage);

                        CFDictionaryRef attachments = CMCopyDictionaryOfAttachments(kCFAllocatorDefault, 
                                                                                    imageDataSampleBuffer, 
                                                                                    kCMAttachmentMode_ShouldPropagate);
                        [self writeCGImageToCameraRoll:cgImageResult withMetadata:(id)attachments];

将其转换CGImage为UIImage这样：UIImage *image = [UIImage imageWithCGImage:<#(CGImageRef)#>];并将其发布到 Facebook，正如您在评论中提到的那样。祝你好运！

编辑 好的，这样做：

UIImage *image = [UIImage imageWithCGImage:cgImageResult];
[fbController addImage:image];
