- 当同一页面同时添加UITapGestureRecognizer 手势与 UITableView 时，为区分手势，可利用UIGestureRecognizerDelegate
中的协议方法进行处理：
#pragma mark - gestureRecognizer
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
if ([NSStringFromClass([touch.view class]) isEqualToString:@"UITableViewCellContentView"]) {
return NO;
}
return YES;
}
