    // 实例化日历对象
    NSCalendar *calendar = [NSCalendar currentCalendar];
   
    // 获取当前时间的秒数
    NSDateComponents *comps = [calendar components:NSCalendarUnitSecond fromDate:[NSDate date]];
    // 获取当前时间的分钟数
    NSDateComponents *minute = [calendar components:NSCalendarUnitMinute fromDate:[NSDate date]];
    // 获取当前时间的分钟数
    NSDateComponents *hour = [calendar components:NSCalendarUnitHour fromDate:[NSDate date]];
   // NSLog(@"%.2f", 10/0.3);
   
    // 设置秒针的旋转
    CGFloat angle = degree2angle(comps.second * 360 / 60);
    self.secondView.transform = CGAffineTransformMakeRotation(angle);
    // 设置分针的旋转
    CGFloat angleM = degree2angle(minute.minute * 360 / 60);
    self.minuteView.transform = CGAffineTransformMakeRotation(angleM);
    // 设置时针的旋转
    CGFloat angleH = degree2angle(hour.hour*30 + minute.minute/10.0 *5);
    self.hourView.transform = CGAffineTransformMakeRotation(angleH);
   // (hour*30) + (minutes/10)*6
