在使用抽屉菜单 MMDrawerController的过程中，发现经常遇到一个问题：
1.在不该出现侧滑的地方出现了侧滑；
2.侧滑后pushviewcontroller卡住；
排查了很久找到了问题，是navigationController中得interactivePopGestureRecognizer和MMDrawerController两者冲突导致的。
我们通常开启边缘返回手势的方法是 self.navigationController.interactivePopGestureRecognizer.delegate = self; 这个就相当于开启了一个手势：在屏幕最左侧向最右侧滑动时会popViewController。
//添加边缘返回手势
if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
self.navigationController.interactivePopGestureRecognizer.delegate = (id)self;
}
对于MMDrawerController我们如果开启了手势打开/关闭:
[drawerControlller setMaximumRightDrawerWidth:200.0];
[drawerControlller setOpenDrawerGestureModeMask:MMOpenDrawerGestureModeAll];
[drawerControlller setCloseDrawerGestureModeMask:MMCloseDrawerGestureModeAll];
[[MMExampleDrawerVisualStateManager sharedManager] setLeftDrawerAnimationType:MMDrawerAnimationTypeSlideAndScale];
两者如果都同时开启，频繁滑动侧滑菜单有时就会出现PushViewController没有响应的情况，
解决方法：
1.对于MMDrawderController:
在开启侧滑功能的viewcontroller.view消失的时候关闭侧滑功能，出现的时候再打开：
- (void) viewDidAppear:(BOOL)animated{
[super viewDidAppear:animated];
self.navigationController.interactivePopGestureRecognizer.enabled = NO;
[[MPCDrawerControlller sharedDrawerController] setOpenDrawerGestureModeMask:MMOpenDrawerGestureModeAll];
}
- (void)viewDidDisappear:(BOOL)animated
{
[super viewDidDisappear:animated];
self.navigationController.interactivePopGestureRecognizer.enabled = YES;
[[MPCDrawerControlller sharedDrawerController] setOpenDrawerGestureModeMask:MMOpenDrawerGestureModeNone];
}
