我在我们的应用程序中显示UIView叠加层，方法是将视图包含在父视图中的两个兄弟之一中，并将frame.y坐标放在屏幕底部。然后，我将这个框架的移动设置为兄弟姐妹的动画。 hiddenYOrigin值是一个浮点数，用于保存原始的屏幕外y值：
- (void)awakeFromNib
{
hiddenYOrigin = self.frame.origin.y;
}
然后我从另一个视图调用showAnimated：
- (void)showAnimated
{
CGRect frame = self.superview.frame;
frame.origin.y = -hiddenYOrigin + 20;
[UIView animateWithDuration:0.4 animations:^{
self.superview.frame = frame;
} completion:^(BOOL finished){
[self.controller overlayDidShow:self];
}];
}
这确实显示了叠加层，并且是我们在其他应用中使用的完全相同的机制，但无论出于何种原因，此应用中叠加层对触摸完全没有响应。它有几个按钮用于各种操作，包括隐藏覆盖图，但没有接收任何触摸。
我添加了一个hitTest函数来调试是否有任何触摸通过，但没有任何触摸触发hitTest。
有什么想法吗？

我收集您发布的代码是您创建的自定义UIView子类的实现的一部分吗？
为什么要操纵超级视图的框架？这看起来并不正确。
对于给定视图，其边界位于其局部坐标系中，并且视图的框架位于父视图的坐标系中。操作视图的frame.origin将视图移动到其父视图中。操纵视图的superview.frame将在 ITS 超级视图中移动超视图，这看起来不正确，可能会产生意想不到的副作用。

因为我永远无法确定为什么其中一个兄弟视图（在我的情况下是parentViewController.rightDrawer）捕获了所有的触摸而不是覆盖，我只是在处理并提出了这个解决方案：
在显示叠加层时，我会在视图中添加一个UITapGestureRecognizer，以便继续抓取触摸：
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(handleTap:)];
tap.delegate = self;
[self.parentViewController.rightDrawer addGestureRecognizer:tap];
然后让我的handleTap函数翻译CGPoints并激活相应的代码：
- (void)handleTap:(UITapGestureRecognizer *)sender
{
if (sender.state == UIGestureRecognizerStateEnded)
{
CGPoint touchPoint = [sender.view convertPoint:[sender locationInView:[sender.view self]] toView:self.scanOverlay];
if (CGRectContainsPoint(self.bottomScanButton.frame, touchPoint)) {
[self bottomScanButtonPressed:self.bottomScanButton];
}
else if (CGRectContainsPoint(self.scanOverlay.closeButton.frame, touchPoint)) {
[self hideScanOverlayAnimated:YES didScan:NO];
}
else if (CGRectContainsPoint(self.scanOverlay.modeButton.frame, touchPoint)) {
[self.scanOverlay modeButtonPressed:self.scanOverlay.modeButton];
}
}
}
由于我只有三个具有任何用户交互的按钮，我只是检测转换后的接触点是否正在触摸我的任何控件并激发正确的逻辑。
然后在隐藏我的叠加层时，我删除了点击识别器：
// Remove the tap recognizer that was added to catch the taps coming from the right drawer
for (UIGestureRecognizer *recognizer in self.parentViewController.rightDrawer.gestureRecognizers) {
if([recognizer isKindOfClass:[UITapGestureRecognizer class]]) {
[self.parentViewController.rightDrawer removeGestureRecognizer:recognizer];
}
}
我本可以创建一个iVar并且只删除一个识别器，但由于我没有任何其他人，我只需要修改任何UITapGestureRecognizer。
Kludgy，但我有截止日期。不幸的是，这就是生活。必须在下一个重构器上捕获它。
