我正在尝试从用户的日历应用程序中获取事件。这本身工作正常，但有一件事并不完全正确。我在不同的标签中显示title、location和。现在，我的问题是两者都晚了一个小时，所以当我将事件设置为 19:00 时，它在我的应用程序中显示为 18:00。我正在使用这段代码：startDateendDateendDatestartDate
// Create the predicate's start and end dates.
CFGregorianDate gregorianStartDate, gregorianEndDate;
CFGregorianUnits startUnits = {0, 0, -30, 0, 0, 0};
CFGregorianUnits endUnits = {0, 0, 15, 0, 0, 0};
CFTimeZoneRef timeZone = CFTimeZoneCopySystem();
gregorianStartDate = CFAbsoluteTimeGetGregorianDate(
CFAbsoluteTimeAddGregorianUnits(CFAbsoluteTimeGetCurrent(), timeZone, startUnits),
timeZone);
gregorianStartDate.hour = 0;
gregorianStartDate.minute = 0;
gregorianStartDate.second = 0;
gregorianEndDate = CFAbsoluteTimeGetGregorianDate(
CFAbsoluteTimeAddGregorianUnits(CFAbsoluteTimeGetCurrent(), timeZone, endUnits),
timeZone);
gregorianEndDate.hour = 0;
gregorianEndDate.minute = 0;
gregorianEndDate.second = 0;
NSDate* startDate =
[NSDate dateWithTimeIntervalSinceReferenceDate:CFGregorianDateGetAbsoluteTime(gregorianStartDate, timeZone)];
NSDate* endDate =
[NSDate dateWithTimeIntervalSinceReferenceDate:CFGregorianDateGetAbsoluteTime(gregorianEndDate, timeZone)];
CFRelease(timeZone);
// Create the predicate.
NSPredicate *predicate = [eventStore predicateForEventsWithStartDate:startDate endDate:endDate calendars:nil]; // eventStore is an instance variable.
// Fetch all events that match the predicate.
NSArray *events = [eventStore eventsMatchingPredicate:predicate];
有人知道如何解决这个问题吗？提前致谢！
