iOS 中经常要进行埋点，我们这里支持 UICollectionViewCell. 进行自动化埋点，思路：
通过hook UICollectionViewCell 的setSelected:方法，
则新的方法中执行埋点逻辑，并调用原来的方法

直接上代码

@implementation UICollectionViewCell (LB)

+ (void)load
{
    instanceMethodExchangeImplementations([self class], @selector(setSelected:), [self class], @selector(setSelectedWithFilter:));
}

-(void)setSelectedWithFilter:(BOOL)selected
{
    // 过滤拼音键盘提示词
    if (selected && !self.skipTrack ) {
        UIView *tempSuperView = self.superview;
        while (tempSuperView) {
            if ([tempSuperView isKindOfClass:[UICollectionView class]]) {
                break;
            }
            tempSuperView = tempSuperView.superview;
        }
        // 非LBScrllView的cell，才由setSelected触发点击采集，LB cell由didSelected触发，
        if (tempSuperView && [tempSuperView isKindOfClass:[UICollectionView class]]
            && ![tempSuperView isKindOfClass:[LBCollectionView class]] && ![tempSuperView isKindOfClass:[LBScrollView class]]) {
            UICollectionView *collectionView = (UICollectionView *)tempSuperView;
            if (![collectionView isDragging] && ![collectionView isTracking] && ![collectionView isDecelerating]) {
                [self setMonitorSelected:selected];
            }
        }
    }
    [self setSelectedWithFilter:selected];
}


- (void)setMonitorSelected:(BOOL)selected
{
    if (selected && !self.skipTrack) {
     //执行埋点逻辑
   }
}

- (void)logClickCell
{
 
}
