Question

我正在使用网页视图来渲染页面，我的网页视图在语音过度运行时运行良好但是当我打开双击工作时，单指滑动工作但是三根手指滑动甚至无法工作，即使是四根手指滑动也可用于切换应用。我可以得到一些帮助。我添加了UISwipeGestureRecognizer，有趣的是，当语音结束时，手势甚至没有调用gestureRecognizer，但语音结束时效果正常

- (void)viewDidLoad
{
    [super viewDidLoad];
    UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self  action:@selector(swipeRightAction:)];
    swipeRight.direction = UISwipeGestureRecognizerDirectionRight;
    [myWebView addGestureRecognizer:swipeRight];
    swipeRight.delegate = self;

    UISwipeGestureRecognizer *swipeLeft = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeLeftAction:)];
    swipeLeft.direction = UISwipeGestureRecognizerDirectionLeft;
    [myWebView addGestureRecognizer:swipeLeft];
    swipeLeft.delegate = self;
    // Do any additional setup after loading the view, typically from a nib.

    [myWebView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"anypage" ofType:@"html" inDirectory:@""] isDirectory:NO]]];
     myWebView.delegate = self;
}

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    return YES;
}

- (void)swipeRightAction:(UISwipeGestureRecognizer *)swipeRight
{
    NSLog(@"Swiped in Right Direction");
    [self.myWebView stringByEvaluatingJavaScriptFromString:@"anyJSFunction();"];
}

- (void)swipeLeftAction:(UISwipeGestureRecognizer *)swipeLeft
{
    NSLog(@"Swiped in Left Direction");
    [self.myWebView stringByEvaluatingJavaScriptFromString:@"anyJSFunction();"];
}

我解决了。需要添加辅助功能滚动。谢谢大家。

- (BOOL)accessibilityScroll:(UIAccessibilityScrollDirection)direction
{
    NSLog(@"Accessibility Scroll Captured");
    return YES;
}

UIWebView滑动不适用于Voice Over
