ios - 如何在iOS中将这些更改为Mac OS X

Question

我想将某些代码从iOS更改为Mac OS X，谁能给我一些提示

UIGraphicsBeginImageContext(CGSizeMake( width , height ));
[image drawInRect:CGRectMake(0, 0,width, height)];
image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

和

UIGraphicsGetImageFromCurrentImageContext();

和

UIImageJPEGRepresentation(newImage, 0.75);

谢谢。
