ios - 使 GoogleMap 在使用 MMDrawerController 时保持其位置

Question

我在我的项目中使用 MMDrawerController 和 GoogleMap 的 api。
我想要一个带有两个左右滑出导航栏的 GoogleMap View ，并且它们仅在我分别从左右滑动 20px 内时出现。
一切都按预期工作，除了:
当我在具有属性的mapView的benzel(20px)上滑动时:

[drawerController
setOpenDrawerGestureModeMask:MMOpenDrawerGestureModeBezelPanningCenterView];

它还使 googlemap 的 View 也响应平移手势，并使其滑开。

关闭手势

[drawerController setCloseDrawerGestureModeMask:MMCloseDrawerGestureModeAll];

工作正常

[drawerController 
setCenterHiddenInteractionMode:MMDrawerOpenCenterInteractionModeNone];

滑出抽屉时如何使 map 保持静止？

谢谢 !

我找到了解决方案。归功于 https://github.com/kcharwood .我只是修改了他的一些代码。

- (void)viewDidLoad
{
self.view = _mapView;

    [[self.view.subviews[0] gestureRecognizers] enumerateObjectsUsingBlock:^(UIGestureRecognizer * gesture, NSUInteger idx, BOOL *stop){
        [gesture setDelegate:self];
    }];
}

-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch{
    CGPoint location = [touch locationInView:self.view];
    CGRect boundingRect = self.view.bounds;
    if([gestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]]){
        boundingRect.origin.x+=20;
        boundingRect.size.width-=40;
    }
    return CGRectContainsPoint(boundingRect, location);
}


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

注意:坚持 gestureRecognizer: shouldRecognizeSimultaneouslyWithGestureRecognizer:将可用。

20和40表示 View 的左右区域。如果平移手势在这些区域内的起始位置， map 将不会移动。
如果你只想剩下:将它们更改为 20 和 20。
如果您希望它们更小，例如 10 和 20，请记住更改 CGFloat const MMDrawerBezelRange = 20.0f; (默认值)在 MMDrawerController.m 中为 10。

通过简单地将 UIGestureRecognizers 捆绑在一起，我找到了一个更优雅的解决方案，以便抽屉的平移手势取代 map 的平移手势:

// walk the drawer controller's gesture recognizers
UIGestureRecognizer *drawerPanGestureRecognizer = nil;
for (UIGestureRecognizer *gestureRecognizer in drawerController.view.gestureRecognizers) {
    // grab the pan gesture recognizer
    if ([gestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]]) {
        drawerPanGestureRecognizer = gestureRecognizer;
        break;
    }
}

// walk the map view's gesture recognizers
for (UIGestureRecognizer *gestureRecognizer in ((UIView *)mapView.subviews[0]).gestureRecognizers) {
    // to find the pan gesture recognizer
    if ([gestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]]) {
        // panning the drawer should prevent panning the map view
        [gestureRecognizer requireGestureRecognizerToFail:drawerPanGestureRecognizer];
        break;
    }
}
