CGRect rect =self.view.frame;
UIGraphicsBeginImageContext(rect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
[self.view.layer renderInContext:context];
UIImage *img = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
float originX ;
float originy ;
float width ;
float height ;
//你需要的區(qū)域起點,寬,高;
CGRect rect1 = CGRectMake(originX , originY , width , height);
UIImage * imgeee = [UIImage imageWithCGImage:CGImageCreateWithImageInRect([img CGImage], rect1)];

主要就是下面這句
UIImage *resultImg = [UIImage imageWithCGImage:CGImageCreateWithImageInRect(img.CGImage, rect)];
