timer

定时器,倒计时管理.周期执行，超时处理。服务器时间同步。

###Feature

只维持一个定时器来实现：所有需要循环定时的操作；
支持超时之后的处理；
支持自动移除超时的obj；
支持设置服务器时间,同步，
- 需要你实现定时校对，可避免本地时间被修改导致倒计时不准确的问题；
- 设置服务器时间后可以对服务器时钟进行本地模拟
- 快慢时钟，模拟用的是10秒一次的低频率时钟（即，一分钟定时器只执行6次来更新服务器时间），当有obj才使用高频率时钟

todo：

I dont know now....Please give me some ideas.

    /*
     *可以网络获取服务器时间对manager进行设置先。
     *当有设置服务器时间的时候会按照10秒一次的时间进行时钟，避免不必要的执行
     */
    NSTimeInterval delayInterval = [[NSDate date] timeIntervalSince1970] + 20;
    [[JPTimeTickManager shareTickManager]addTimeTickLabel:self.timeL withExpiresTime:delayInterval prefix:@"我在倒计时: " withExpiresHandler:^(JPTimeTickObj *obj) {
        NSLog(@"我是handler, obj:%@", obj);
    }];
