Question

我希望启用一个具有水平滚动功能的大滚动视图。在此滚动ViewIfI 中, 我喜欢有另外5个可以垂直滚动的滚动视图。

谁能指点我正确方向如何处理触摸活动?

我正在考虑做两个手势识别器(1个用于开关,1个用于锅盘),并使用 X 和 Y 值的三角形来计算水平或垂直擦拭。在我检查方向后,我设置了大滚动器或一个滚动器来启用或禁用。这是正确的工具吗?

EDIT: Instead of using my method above I was just able to add my 5 scrollviews(vertical scrolling) in one big scrollview(horizontal) by adding the 5 scrollviews as a subview of the big one. Maybe this code can help someone out as well so provided example code as well.

for (int i = 0; i < NumberOfVerticalScrollers; i++) {
        CGRect frame;
        frame.origin.x = self.scrollView.frame.size.width * i;
        frame.origin.y = 0;
        frame.size = self.scrollView.frame.size;

        UIScrollView *scroller = [[UIScrollView alloc] initWithFrame:frame];
        scroller.directionalLockEnabled = YES;
        scroller.contentSize = CGSizeMake(320, 960);
        [self.scrollView addSubview:scroller];
}
self.scrollView.delegate = self;
self.scrollView.contentSize = CGSizeMake(self.scrollView.frame.size.width * NumberOfVerticalScrollers, self.scrollView.frame.size.height);

Answer 1

您只需要创建能够向水平滚动的主滚动视图, 只需使用 < code> addSubView 方法在主滚动视图上添加其它滚动视图。 iOS 处理所有必要的事件来正确处理滚动。您只需要为每个滚动视图指定正确的 < code> content size 和 < code> frame 。

Answer 2

要做到这一点, 您需要简单地做一个水平滚动视图, 将其它垂直滚动视图添加为子视图。要处理的最大问题是, 底底滚动视图何时会水平滚动, 您应该禁用垂直滚动视图上的滚动。

你可以监听:

- (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView

当发生这种情况时,您可以在垂直滚动视图上禁用滚动

下列各点,您可以使滚动回滚动:

- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate

Answer 3

我不认为你需要做任何事情花哨。

如果你禁用放大和弹射, 你应该看到它只是起作用的。

Answer 4

There s an app called "Pulse" that uses a vertical tableview, where each table view cell can be scrolled horizontally and includes another tableview. This takes care of caching and UI events. You need to find an example of that and evaluate it for your purposes (maybe rotating the default implementation by 90 degrees)
