UIScrollView嵌套UITableView，cell侧滑兼容 iOS适配

界面结构是这样的

界面结构

实现效果是兼容底部sceollView左右滑动和内部cell侧滑操作
通过scrollView的手势代理来兼容table的手势

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRequireFailureOfGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
    if (([otherGestureRecognizer.view isKindOfClass:NSClassFromString(@"UITableViewWrapperView")]) && [otherGestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]]) {
        CGPoint p = [otherGestureRecognizer locationInView:otherGestureRecognizer.view ];
        if (self.otherGestureRecognizerSimultaneously && p.x >= SCREEN_WIDTH-SCREEN_WIDTH/375*50) {
            return YES;
        }
    }
    return NO;
}

附带pop手势兼容

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer { 
    if ([otherGestureRecognizer.view isKindOfClass:NSClassFromString(@"UILayoutContainerView")]) {
        if (otherGestureRecognizer.state == UIGestureRecognizerStateBegan && self.contentOffset.x == 0) {
            return YES;
        }
    }
    return NO;
}

这是iOS11之前的做法，iOS11 的UITableView的调整感觉还满多的，自少目前遇到的情况是这样，对于cell的侧滑兼容需要做一点小改动
cell手势判断条件调整

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRequireFailureOfGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
    //UITableViewCell 自定义手势可能要在此处自行定义
    static Class kUIPanGestureRecognizer, kUITableView;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        kUIPanGestureRecognizer = [UIPanGestureRecognizer class];
        if (@available(iOS 11.0, *)) {
            kUITableView = NSClassFromString(@"UITableView");
        } else {
            kUITableView = NSClassFromString(@"UITableViewWrapperView");
        }
    });
    //self.otherGestureRecognizerSimultaneously 启用其它手势
    if (self.otherGestureRecognizerSimultaneously && [otherGestureRecognizer isKindOfClass:kUIPanGestureRecognizer] &&  [otherGestureRecognizer.view isKindOfClass:kUITableView]) {
        CGPoint p = [otherGestureRecognizer locationInView:otherGestureRecognizer.view];
        CGFloat w = CGRectGetWidth(otherGestureRecognizer.view.bounds);
        if (p.x >= w - 50) {
            return YES;
        }
//        if (p.x <= 50) {
//            return YES;
//        }
    }
    return NO;
}

这样cell的侧滑操作就能够正常兼容iOS11了。
以上代码只是粗略处理滑动冲突，需要精确可根据p的位置对对应cell（【bool CGRectContainsPoint(CGRect rect, CGPoint point)】）进行侧滑事件判断处理。
