Hello

[0x30]

thank you very much!
Thank you very much, but I hope you can adjust some parameters, about the direction of the image.

// 需传入方向和缩放比例，否则方向和尺寸都不对
UIImage *tempImg = [UIImage imageWithCGImage:asset.defaultRepresentation.fullResolutionImage 
                                       scale:asset.defaultRepresentation.scale 
                                 orientation:(UIImageOrientation)asset.defaultRepresentation.orientation];
