对日历守护程序的谓词调用失败：错误域 = EKCADErrorDomain 代码 = 1013“操作无法完成。（EKCADErrorDomain 错误 1013。）”
我正在尝试从默认应用中获取提醒。
if([eventStore respondsToSelector:@selector(requestAccessToEntityType:completion:)]) {
// need user permission for iOS 6 and later
[eventStore requestAccessToEntityType:EKEntityTypeReminder completion:^(BOOL granted, NSError *error) {
if (granted) {
//---- codes here when user allow your app to access theirs' calendar.
[self performCalendarActivity:eventStore];
}
else {
//----- codes here when user NOT allow your app to access the calendar.
}
}];
}
---- 获取日期提醒-----
-(void)performCalendarActivity:(EKEventStore*)evtStore
{
self.eventsList = [[NSMutableArray alloc] initWithArray:0];
int seconds_in_day = 60*60*24;// 1 day = 60*60*24 seconds = 86400 seconds
NSDate *endDate = [startDate dateByAddingTimeInterval:seconds_in_day];
// use Dictionary for remove duplicates produced by events covered more one year segment
NSMutableDictionary *eventsDict = [NSMutableDictionary dictionaryWithCapacity:1024];
NSDate* currentStart = [NSDate dateWithTimeInterval:0 sinceDate:startDate];
NSDate* currentFinish = [NSDate dateWithTimeInterval:seconds_in_day sinceDate:currentStart];
if ([currentFinish compare:endDate] == NSOrderedDescending) {
currentFinish = [NSDate dateWithTimeInterval:0 sinceDate:endDate];
}
NSMutableArray *events = [NSMutableArray arrayWithObjects: nil];
NSArray *calendars = [eventStore
calendarsForEntityType:EKEntityTypeReminder];
NSPredicate *predicate = [eventStore predicateForRemindersInCalendars:calendars];
//NSPredicate *predicate = [eventStore predicateForIncompleteRemindersWithDueDateStarting:startDate ending:currentFinish calendars:calendars];
[eventStore fetchRemindersMatchingPredicate:predicate completion:^(NSArray *ekReminders){
[events addObjectsFromArray:ekReminders];
}];
}
我收到此错误：- 对日历守护程序的谓词调用失败：错误域 = EKCADErrorDomain 代码 = 1013“操作无法完成。（EKCADErrorDomain 错误 1013。）”
请帮忙。
