在我基於iPhone的鬧鐘應用程序中，我使用的是tinyfool的TdCalenderView代碼。在那個日曆中，我打電話給setDayFlag：在設置鬧鐘的那天的drawDateWords方法中的日期。觸發日期打開鬧鐘列表爲相應的日期。 現在，我也在同一個應用程序中使用Tab欄。在單擊標籤欄的項目0時，我顯示包含日曆和單擊項目1的視圖我正在顯示寫入和保存註釋的視圖。 當我寫一個筆記並保存它時，我想要在相應的日期繪製一個點。 但它沒有發生。點不在那裏。但是當我點擊一次日期時，點出現，並在第二次點擊列表顯示。 這裏是我的代碼：Redraw TdCalendarView
appdelegate.m
calendar=[[TdCalendarView alloc]init];
查看含有標籤欄
這是在此基礎上，我在顯示和隱藏的觀點爲標籤項目標籤切換的情況下
switch (tag) {
case 0:

RecordANoteView.hidden=YES;
BirthdayView.hidden=YES;
AllNotesView.hidden=NO;

我沒有得到這是爲什麼happening.Any幫助將不勝感激。
