UISlider只能滑动一小段距离 [英] UISlider only slide a small distance

问题描述

因此，我使用以下代码将UISlider置于视图中，但一次只能滑动约10个点。它只能在大约20点的范围内来回拖动。为什么？

So I've put a UISlider into a view with the following code, but it could only be slided for the distance of about 10 points a time. It can only be dragged back and forth within a range of about 20 points. Why?

v = [[UIView alloc] initWithFrame:someFrame];
UISlider *slider = [[UISlider alloc] initWithFrame:CGRectMake(10, 10, 200, 30)];
[v addSubview:slider];
[self.view addSubview:v];

我已将此代码放入另一个测试项目中，它确实起作用。因此，可能是其他一些代码。我想知道以前是否有人遇到过相同的问题。

I've put this code into another test project, it does work. So it might be some other code. I'm wondering if anyone else has been through the same problem before.

推荐答案

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
    if([[touch view] isKindOfClass:[UISlider class]])
    {
        return NO;
    }
}

我正在使用 IIViewDeckController ，因此我将这段代码添加到 IIViewDeckController.m 代码中，它解决了该问题！

I was using IIViewDeckController, so I added this piece into the IIViewDeckController.m code and it solved the problem!
