ios – 根据给定的EKRecurrenceRule不添加EKEvent

概述我正在尝试使用递归规则RRULE将事件添加到日历中：FREQ = YEARLY; BYMONTH = 6,7; BYDAY = 1TH 所以根据这个规则,事件应该每年添加一次,每年的6月1日和7月,直到到期日,我已经在我的项目中设置了. 在我的项目中,会创建事件,但不会根据重复规则创建事件.使用以下代码,事件仅在6月1日星期四添加.为什么每个7月1日星期四都没有添加活动呢？ 这是.m文件代码 - @H_403_2@ 我正在尝试使用递归规则RRulE将事件添加到日历中：FREQ = YEARLY; BYMONTH = 6,7; BYDAY = 1TH

有人可以帮我解决这个问题吗？

解决方法 这似乎是另一个问题的重复.基本上,根据“BYDAY”规则,YEARLY频率的第1周意味着一年中的第一周 – 而不是每个月的第一周.

@Shuvo,我没看过rfc.但这里是Apple文档EKRecurrenceDayOfWeek.

The EKRecurrenceDayOfWeek class represents a day of the week for use with an EKRecurrenceRule object. A day of the week can optionally have a week number,indicating a specific day in the recurrence rule’s frequency. For example,a day of the week with a day value of Tuesday and a week number of 2 would represent the second Tuesday of every month in a monthly recurrence rule,and the second Tuesday of every year in a yearly recurrence rule.

当你说“第一个星期四”时,这是正确的 – 除了在每年的背景下,它是一年的第一个星期四.
