    CGContextSetFillColorWithColor(ctx, [[         


        

Answer 1

You can just set the scale when you start the context

+ (UIImage *)imageWithView:(UIView *)view {
    UIGraphicsBeginImageContextWithOptions([view bounds].size, NO, [[UIScreen mainScreen] scale]);

    [[view layer] renderInContext:UIGraphicsGetCurrentContext()];

    UIImage *result = UIGraphicsGetImageFromCurrentImageContext();

    UIGraphicsEndImageContext();

    return result;
}
