App Google API Calendar 教學 (note)

  

→建立一個新的授權，若您的使用者砍了你的授權，二次想加回去，直接使用這個就好了

[self presentViewController:[self createAuthController] animated:YES completion:nil];

★授權

Google教學一般只給

kGTLAuthScopeCalendarReadonly

要管理的話(能新增修改編輯)授權權限要改為這個

kGTLAuthScopeCalendar

→建立一個日曆 

    GTLCalendarCalendar*newCalendar=[GTLCalendarCalendar object];

 //新名字就是new Calendar

    newCalendar.summary=@"new Calendar";

    GTLQueryCalendar *queryInsertCalendarList = [GTLQueryCalendar queryForCalendarsInsertWithObject:newCalendar];

    [self.service executeQuery:queryInsertCalendarList

                      delegate:self

             didFinishSelector:nil];

→取得日曆列表

- (void)fetchCalendarList {

    GTLQueryCalendar *query = [GTLQueryCalendar queryForCalendarListList];

    [self.service executeQuery:query

                      delegate:self

             didFinishSelector:@selector(Result_CalendarList:finishedWithObject:error:)];

}

- (void)Result_CalendarList:(GTLServiceTicket *)ticket

   finishedWithObject:(GTLCalendarCalendarList *)list

                error:(NSError *)error {

    

    if (error == nil) {

        for(GTLCalendarCalendarListEntry *cal in list.items){

            //cal.identifier;//判定是否有過

            NSLog(@"%@",cal.summary);

        }

        

    } else {

        [self showAlert:@"Error" message:error.localizedDescription];

    }

}

→刪除授權

 [GTMOAuth2ViewControllerTouch removeAuthFromKeychainForName:kKeychainItemName];

→建立一個事件，此事件活動為一整天

[CalendarID]

need change

- (void)CreateEvent{

    GTLCalendarEvent *calEvent =[GTLCalendarEvent object];

    calEvent.summary= @"test";

    calEvent.descriptionProperty=@"i am test";

    

    calEvent.start = [GTLCalendarEventDateTime object];

    calEvent.end = [GTLCalendarEventDateTime object];

    

    calEvent.start.dateTime=[GTLDateTime dateTimeWithDate:[NSDate dateWithTimeIntervalSinceNow:60*60] timeZone:[NSTimeZone localTimeZone]];

    calEvent.end.dateTime=[GTLDateTime dateTimeWithDate:[NSDate dateWithTimeIntervalSinceNow:60*60+60*60] timeZone:[NSTimeZone localTimeZone]];

    GTLDateTime *startDateTime = [GTLDateTime dateTimeForAllDayWithDate:[NSDate date]

                                                     ];

    

    calEvent.start = [GTLCalendarEventDateTime object];

    calEvent.start.date = startDateTime;

    

    calEvent.end = [GTLCalendarEventDateTime object];

    calEvent.end.date=startDateTime;

    

    

    GTLQueryCalendar *query = [GTLQueryCalendar queryForEventsInsertWithObject:calEvent calendarId:@"[CalendarID]" ];//日曆id

    

    [self.service executeQuery:query

                      delegate:self

             didFinishSelector:@selector(Result_CreateEvent:finishedWithObject:error:)];

}

//結果顯示

- (void)Result_CreateEvent:(GTLServiceTicket *)ticket

           finishedWithObject:(GTLCalendarEvent *)events

                        error:(NSError *)error {

    if (error == nil) {

        //events.identifier; 新增事件iid

    } else {

        [self showAlert:@"Error" message:error.localizedDescription];

    }

}

→編輯一個事件，更新時間為目前時間1小時後的事件

[CalendarID]

[EventID]

need change

   GTLCalendarEvent *calEvent =[GTLCalendarEvent object];

    calEvent.summary= @"change test";

    calEvent.descriptionProperty=@"i am change test";

    

    calEvent.start = [GTLCalendarEventDateTime object];

    calEvent.end = [GTLCalendarEventDateTime object];

    

    calEvent.start.dateTime=[GTLDateTime dateTimeWithDate:[NSDate dateWithTimeIntervalSinceNow:60*60] timeZone:[NSTimeZone localTimeZone]];

    

    

    calEvent.end.dateTime=[GTLDateTime dateTimeWithDate:[NSDate dateWithTimeIntervalSinceNow:60*60+60*60] timeZone:[NSTimeZone localTimeZone]];

    

    NSDate *anHourFromNow = [NSDate dateWithTimeIntervalSinceNow:60*60];

    GTLDateTime *startDateTime = [GTLDateTime dateTimeWithDate:[NSDate date]

                                                      timeZone:[NSTimeZone systemTimeZone]];

    GTLDateTime *endDateTime = [GTLDateTime dateTimeWithDate:anHourFromNow

                                                    timeZone:[NSTimeZone systemTimeZone]];

    

    calEvent.start = [GTLCalendarEventDateTime object];

    calEvent.start.dateTime = startDateTime;

    

    calEvent.end = [GTLCalendarEventDateTime object];

    calEvent.end.dateTime = endDateTime;

    

    

    GTLQueryCalendar *query = [GTLQueryCalendar queryForEventsUpdateWithObject:calEvent

                                                                    calendarId:@"[CalendarID]"                                    eventId:@"[EventID]"];//日曆id

    

    

    [self.service executeQuery:query

                      delegate:self

             didFinishSelector:nil];

}

→刪除一個事件

[CalendarID]

[EventID]

need change

GTLQueryCalendar *query = [GTLQueryCalendar queryForEventsDeleteWithCalendarId:@"[CalendarID]"   eventId:@"[EventID]"];//日曆id

[self.service executeQuery:query delegate:selfdidFinishSelector:nil];
