EKCalender創建日曆，但無法在iCal中看到它

Question

我正試圖在iCal中創建新日曆。現在我可以用某個名稱創建一個新日曆。但我的問題是，當我嘗試創建到本地日曆時，我無法在日曆列表中看到它。任何人對此有任何想法？我嘗試過使用所有類型的數據源，但無法找到確切的解決方案。

預先感謝您。

NSMutableArray *arrAlarm = [[NSMutableArray alloc]init]; 
EKAlarm *alarm1 = [EKAlarm alarmWithRelativeOffset:3600]; 
EKAlarm *alarm2 = [EKAlarm alarmWithRelativeOffset:-3600]; //86400 1 day  
[arrAlarm addObject:alarm1]; 
[arrAlarm addObject:alarm2]; 
EKEventStore *eventStore = [[EKEventStore alloc] init]; 
EKEvent *ekevent = [EKEvent eventWithEventStore:eventStore]; 
ekevent.title = strname; 

NSLog(@"%@",ekevent.startDate); 

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 
[dateFormatter setDateFormat:@"EEE MMM d,yyyy"]; 
NSDate *date = [dateFormatter dateFromString:strdate]; 

// Convert to new Date Format 
[dateFormatter setDateFormat:@"YYYY-MM-DD HH:MM:SS ±HHMM"]; 
NSString *newDate = [dateFormatter stringFromDate:date]; 

// dateFormatter = [[[NSDateFormatter alloc] init] autorelease]; 
// [dateFormatter setLocale:[[[NSLocale alloc] initWithLocaleIdentifier:@"en_US_POSIX"] autorelease]]; 
[dateFormatter setDateFormat:@"hh:mm a"]; 

NSDate* firstDate = [dateFormatter dateFromString:time]; 
NSDate* secondDate = [dateFormatter dateFromString:endtime]; 

NSTimeInterval timeDifference = [secondDate timeIntervalSinceDate:firstDate]; 

// Convert to new Date Format 
[dateFormatter setDateFormat:@"HH:MM"]; 
NSString *t11 = [dateFormatter stringFromDate:firstDate]; 
NSString *t12 = [dateFormatter stringFromDate:secondDate]; 
NSDate *dt1 = [dateFormatter dateFromString:t11]; 
NSDate *dt2 = [dateFormatter dateFromString:t12];  

NSDateFormatter *df = [[NSDateFormatter alloc] init]; 
[df setDateFormat:@"hh"]; 
NSString *hourstring = [NSString stringWithFormat:@"%@", 
         [df stringFromDate:dt1]]; 
[df setDateFormat:@"mm"]; 
NSString *minstring = [NSString stringWithFormat:@"%@", 
         [df stringFromDate:dt1]]; 
[df release]; 
NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar]; 
NSDateComponents *components = [gregorian components: NSUIntegerMax fromDate: date]; 
[components setHour: [hourstring intValue]]; 
[components setMinute: [minstring intValue]]; 
[components setSecond: 00]; 

// NSDate *newDate = [gregorian dateFromComponents: components]; 
[gregorian release]; 

ekevent.startDate = date; 

ekevent.endDate = [[NSDate alloc] initWithTimeInterval:timeDifference sinceDate:date]; 
[ekevent setCalendar:[eventStore defaultCalendarForNewEvents]]; 
ekevent.alarms = arrAlarm; 
[arrAlarm release]; 
NSError *err; 
[eventStore saveEvent:ekevent span:EKSpanThisEvent error:&err]; 

試試這個代碼，你會得到想要的結果。
