        [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    NSURL *url = [NSURL URLWithString:@"yourimageurl"];
    NSURLRequest *req = [NSURLRequest requestWithURL:url];
    [webV loadRequest:req];

    UITapGestureRecognizer *gs = [[UITapGestureRecognizer alloc] init];
    gs.numberOfTapsRequired = 1;
    gs.delegate = self;
    [self.view addGestureRecognizer:gs];
    }


-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
    NSLog(@"TAPPED");
    //Touch gestures below top bar should not make the page turn.
    //EDITED Check for only Tap here instead.
    if ([gestureRecognizer isKindOfClass:[UITapGestureRecognizer class]]) {
        CGPoint touchPoint = [touch locationInView:self.view];

        NSUserDefaults * userDefaults = [NSUserDefaults standardUserDefaults];
        bool pageFlag = [userDefaults boolForKey:@"pageDirectionRTLFlag"];
        NSLog(@"pageFlag tapbtnRight %d", pageFlag);

        if(self.interfaceOrientation==UIInterfaceOrientationPortrait||self.interfaceOrientation==UIInterfaceOrientationPortraitUpsideDown) {
            NSString *imgURL = [NSString stringWithFormat:@"document.elementFromPoint(%f, %f).src", touchPoint.x, touchPoint.y];
            NSString *urlToSave = [webV stringByEvaluatingJavaScriptFromString:imgURL];
            NSLog(@"urlToSave :%@",urlToSave);
            NSURL * imageURL = [NSURL URLWithString:urlToSave];
            NSData * imageData = [NSData dataWithContentsOfURL:imageURL];
            UIImage * image = [UIImage imageWithData:imageData];
            imgView.image = image;
        }
    }
    return YES;
}

是的，我已经按照你说的做了，我的问题是在我在webview中修改了这张照片之后，如何用相同或不同的名称保存回文档目录或照片库检查答案可能是这是解决你的问题。是的，我已经按照你说的做了，我的问题是，我在webview中修改了这张照片，然后如何用相同或不同的名称保存回文档目录或照片库检查答案可能是这可以解决您的问题。感谢它的工作…NSString*imgURL=[NSString stringWithFormat:@“document.elementFromPoint（%f，%f）.src”，touchPoint.x，touchPoint.y]；NSString*urlToSave=[webV stringByEvaluatingJavaScriptFromString:imgURL]；这里它使用了这个手势，对吗？如果我们通过图像标记id获取imgURL会更好。感谢它的工作…NSString*imgURL=[NSString stringWithFormat:@“document.elementFromPoint（%f，%f）.src”，touchPoint.x，touchPoint.y]；NSString*urlToSave=[webV stringByEvaluatingJavaScriptFromString:imgURL]；这里它使用了这个手势，对吗？如果我们通过图像标记id获取imgURL，那就更好了。。
