iOS 11系统UITableViewCell的左滑删除失效

[CoderMC]

iOS 11系统，UITableViewCell的左滑删除很难触发，多试几次也可以触发。iOS 11 以下系统没这个bug. WMScrollView里面的方法不起作用了

• (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRequireFailureOfGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer { //MARK: UITableViewCell 删除手势 if ([NSStringFromClass(otherGestureRecognizer.view.class) isEqualToString:@"UITableViewWrapperView"] && [otherGestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]]) { return YES; } return NO; }

iOS11 都不走 return YES

• (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRequireFailureOfGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {

  //MARK: UITableViewCell 删除手势 if ([NSStringFromClass(otherGestureRecognizer.view.class) isEqualToString:@"UITableViewWrapperView"] && [otherGestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]]) { return YES; } return NO; }

当滑动在VC的tableview上时-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer方法返回YES,但这样会出现tableview左滑时上下滑动的问题,需要在scrollview代理方法中做处理,左滑时禁止tableview滑动.这样处理就导致没法pod管理,作者也建议在外边处理手势冲突,目前还没想到在外边处理的方法.

此问题有解决方法了吗？

想到一个笨办法： /* 在需要左滑的控制器里面保存一个全局标识 */

• (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [HSShareData sharedInstance].isExpandQACollectPage = YES; }
• (void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; [HSShareData sharedInstance].isExpandQACollectPage = NO; }

#import "WMScrollView+HSAdd.h" /* 添加WMScrollView分类，加上下面这个代理方法 */ @implementation WMScrollView (HSAdd)

• (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer { if ([HSShareData sharedInstance].isExpandQACollectPage && [otherGestureRecognizer.className isEqualToString:@"_UISwipeActionPanGestureRecognizer"]) return YES; return NO; }

结果在我当前应用是完美解决。备注：可能全局变量也不需要，这个没有试，但我觉得加上会保险一些。
