2 iOS UIScrollView截图，长图截取办法

- (UIImage*)getCapture:(UIScrollView *)scrollView
{
    CGPoint savedContentOffset = scrollView.contentOffset;
    CGRect savedFrame = scrollView.frame;
    
    scrollView.frame = CGRectMake(0, scrollView.frame.origin.y, scrollView.contentSize.width, scrollView.contentSize.height);
    UIGraphicsBeginImageContextWithOptions(scrollView.contentSize, YES, 0.0); //currentView 当前的view  创建一个基于位图的图形上下文并指定大小为
    [scrollView.layer renderInContext:UIGraphicsGetCurrentContext()];//renderInContext呈现接受者及其子范围到指定的上下文
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();//返回一个基于当前图形上下文的图片
    
    scrollView.contentOffset = savedContentOffset;
    scrollView.frame = savedFrame;
    
    UIGraphicsEndImageContext();
    
    if (image) {
        UIImageWriteToSavedPhotosAlbum(image, self, @selector(image:didFinishSavingWithError:contextInfo:), NULL);
    }
    return image;
}
//回调方法
- (void)image: (UIImage *) image didFinishSavingWithError: (NSError *) error contextInfo: (void *) contextInfo
{
    NSString *msg = nil ;
    if(error != NULL){
        msg = @"保存图片失败" ;
        
        [MBProgressHUD showSAToast:Type_Msg msg:msg];
    }
    else{
        msg = @"保存图片成功" ;
    }
}
