我正在嘗試將Kal日曆應用到我自己的項目中。我已經下載了一個github項目的副本並在模擬器上運行它。一切工作正常，並顯示來自模擬器日曆的數據。Kal日曆在模擬器中抓取日曆中的數據但不在設備上
但是，當我在真實的設備上測試它。它不提取數據，它給我以下錯誤。
CalendarApp[1024:1103] Predicate call to calendar daemon failed: Error Domain=EKCADErrorDomain Code=1013 "The operation couldn’t be completed. (EKCADErrorDomain error 1013.)"
這就是我的抓取方式。
- (void)presentingDatesFrom:(NSDate *)fromDate to:(NSDate *)toDate delegate:(id<KalDataSourceCallbacks>)delegate
{
// asynchronous callback on the main thread
[events removeAllObjects];
NSLog(@"Fetching events from EventKit between %@ and %@ on a GCD-managed background thread...", fromDate, toDate);
dispatch_async(eventStoreQueue, ^{
NSDate *fetchProfilerStart = [NSDate date];
NSPredicate *predicate = [eventStore predicateForEventsWithStartDate:fromDate endDate:toDate calendars:nil];
NSArray *matchedEvents = [eventStore eventsMatchingPredicate:predicate];
dispatch_async(dispatch_get_main_queue(), ^{
NSLog(@"Fetched %d events in %f seconds", [matchedEvents count], -1.f * [fetchProfilerStart timeIntervalSinceNow]);
[events addObjectsFromArray:matchedEvents];
[delegate loadedDataSource:self];
});
任何人都可以幫助我嗎？
親切的問候和提前致謝
