在UITableView上添加了UITapGestureRecognizer后会导致didSelectRowAtIndexPath失效，原因是UITapGestureRecognizer会截取了tableView的touch事件，导致无法响应行选择，解决方法是重写UIGestureRecognizerDelegate中的

-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
    if ([NSStringFromClass([touch.view class]) isEqualToString:@"UITableViewCellContentView"]) {//如果当前是tableView
        //做自己想做的事
        return NO;
    }
    return YES;   
}
