iOS - EKEvent 重复规则中的 iCal rRule

Question

我有一个带有 rRule 的 iCal 文件: rRule = "FREQ=WEEKLY;UNTIL=20140425T160000Z;INTERVAL=1;BYDAY=TU,TH";

我需要将此信息放入 EKEvent 中:

EKEvent *event;
event.recurrenceRules = ...

我拆分了 rRule 并将其保存在 NSArray 中:

 NSArray * rules = [evento.rRule componentsSeparatedByString:@";"];
 event.recurrenceRules = rules;

但是出现错误:

-[__NSCFString relationForKey:]: unrecognized selector sent to instance 0x21283350
 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString relationForKey:]: unrecognized selector sent to instance 0x21283350'

你能帮帮我吗？ 感谢您的提前。

我找到了使用 EKRecurrenceRule+RRULE 库的解决方案，它非常易于使用。

使用示例:

NSString *rfc2445String = @"FREQ=MONTHLY;BYDAY=MO,TU,WE,TH,FR;BYSETPOS=-2"; // The 2nd to last weekday of the month

// Result
EKRecurrenceRule *recurrenceRule = [[EKRecurrenceRule alloc] initWithString:rfc2445String];
NSLog(@"%@", recurrenceRule);
