Question

我想在 iPhone日历中添加活动，我在iPhone日历中成功添加了活动。但是，我希望获得所有当前月份活动，并且我想在 MFMailComposer 中附加事件文件（.ical）。

Answer 1

阅读事件非常简单。

// Create the predicate from the event store's instance method
NSPredicate *predicate = [store predicateForEventsWithStartDate:startOfTheMonth
                                                        endDate:endOfTheMonth
                                                      calendars:nil];
// Fetch all events that match the predicate
NSArray *events = [store eventsMatchingPredicate:predicate];

apple docs中的更多信息。

要获得月末的开始和结束，您可以使用此项目中的示例：https://github.com/melsam/NSDateCategoryForReporting

并以此为例将如何将事件导出到.ical文件 https://github.com/mysterioustrousers/EKEventToiCal/blob/master/EKEventToiCal/

要发送.ical文件，请使用IronManGill的代码回答，但将mimeType更改为text / calendar

[picker addAttachmentData:data mimeType:@"text/calendar" fileName:@"/abc.ical"];

将其与MFMailComposer中的电子邮件一起附加

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; picker.mailComposeDelegate = self; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

NSString *documentsDirectory = [paths objectAtIndex:0];    
NSString *WritableDBPath= [documentsDirectory stringByAppendingPathComponent:kFilename];    
NSData *data = [NSData dataWithContentsOfFile:WritableDBPath];    
[picker addAttachmentData:data mimeType:@"application/zip" fileName:@"/abc.zip"];
[picker setSubject:@"Database"];    
[picker setMessageBody:@"Database testing" isHTML:NO];    
[self presentModalViewController:picker animated:YES];

希望这会有所帮助。
