Question

我有一个启用了分页的UIScrollView，如下所示：

container = [[UIScrollView alloc] initWithFrame:kScrollViewFrame];
[container setDelegate:self];
[container setShowsHorizontalScrollIndicator:YES];
[container setShowsVerticalScrollIndicator:NO];
[container setClipsToBounds:YES];
[container setPagingEnabled:YES];
[container setDecelerationRate:UIScrollViewDecelerationRateFast];
[container setBounces:NO];
[container setUserInteractionEnabled:NO];
[container setCanCancelContentTouches:NO];
[container setDelaysContentTouches:NO];

在UIScrollView中，我添加了几个UIWebViews，并将其启用的交互设置为是这样的。

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        // Initialization code

        self.frame = frame;
        self.userInteractionEnabled = YES;
    }
    return self;
}

打破了UIScrollView上的分页和所有触摸。如果我将用户交互设置为NO，则页面有效，但我无法在UIWebView中突出显示文本。我试着像下面这样对UIScrollView进行子类化，但是会出现同样的情况。有什么想法吗？

- (id)initWithFrame:(CGRect)frame
{
    NSLog(@"init");
    return [super initWithFrame:frame];
}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"touchesBegan");

    [[self nextResponder] touchesBegan:touches withEvent:event];
}

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"touchesMoved");

    [[self nextResponder] touchesMoved:touches withEvent:event];
}

- (void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    NSLog(@"touchesEnded");
    [[self nextResponder] touchesEnded:touches withEvent:event];
}

在容器上禁用用户交互也会在子视图上有效地禁用它。您应该启用它，使触摸事件沿视图层次结构向下传播;

[container setUserInteractionEnabled:YES];

如果要在UIWebView上禁用滚动，只需进入其UIScrollView

yourWebView.scrollView.scrollEnabled = NO;

我已经在我的设备上对此进行了测试，我可以通过＆＃34;翻页和＃34; UIScrollView并在UIWebView上选择文本。

编辑：

我得到了这个工作！您还必须允许触摸取消：

[container setCanCancelContentTouches:YES];

UIScrollView内容不允许用户交互
