Posted 2023-02-25

【中文标题】我希望我的闹钟每天在选定的时间重复，并在 iPhone 中具有贪睡功能

【英文标题】：i want my alarm to be repeat every day at selected time with snooze functionality in iPhone

【问题描述】：

我想在我的闹钟应用程序中具有重复功能，但我无法做到。任何人都可以以任何方式帮助我......比如伪代码或告诉如何做，或一些教程等。

我的闹钟没有在正确的时间调用，它总是延迟一段时间，有时延迟 50 秒，哈哈。应该为此做些什么。

这是我到目前为止所做的代码......

【参考方案1】：

使用此代码可能对您有帮助...

EKEventStore *eventStore = [[EKEventStore alloc] init];

    EKEvent *event  = [EKEvent eventWithEventStore:eventStore];
    event.title     = @"EVENT TITLE";

    NSDateFormatter* df = [[NSDateFormatter alloc] init];
    [df setDateFormat:@"MM/dd/yyyy"];
     event.startDate = [df dateFromString:@"your selected date"];


    NSLog(@"start date is %@",event.startDate);
    event.endDate   = [[NSDate alloc] initWithTimeInterval:600 sinceDate:event.startDate];
    //NSLog(@"end date %@",event.endDate);

    [event setCalendar:[eventStore defaultCalendarForNewEvents]];
    //NSLog(@"events are %@",event);
    //NSLog(@"events are %@",eventStore);
    NSError *err;
    [eventStore saveEvent:event span:EKSpanThisEvent error:&err];

它显示设置特定日期和时间导入 EventKit 框架的警报

感谢您的代码...让我检查一下，如果它有效，我很乐意接受答案.. :) 什么是 EKEventScore、EKEvent 和 EKSpanThisEvent？？
