私はこのような NSDictionary の配列を持っています。

 {
    id = 12;
    "time_from" = "12:00";
    "time_to" = "16:00";
    "timing_name" = Lunch;
},
    {
    id = 11;
    "time_from" = "08:00";
    "time_to" = "12:00";
    "timing_name" = BreakFast;
},
    {
    id = 13;
    "time_from" = "09:00";
    "time_to" = "10:00";
    "timing_name" = Dinner;
}

私の現在の時刻が 8:45 だとすると、現在の時刻が time_from と time_to の間にある場合、述語を使用して正確な辞書を見つけるにはどうすればよいでしょうか。

実際には、述語が必要です。
