我正在尝试从我的应用程序将事件保存到日历中。我的代码适用于 iOS 7，但在iOS 6上，它返回No calendar has been set。
在 iOS 7 上，应用程序提示用户授予对日历的访问权限。但在 iOS 6 上不会出现此类提示。尽管应用程序在设置->隐私->日历中被授予访问权限。
是的，我已经实施了requestAccessToEntityType:completion:.
这是我的代码片段。
EKEventStore *objStore = [[EKEventStore alloc]init];
if ([objStore respondsToSelector:@selector(requestAccessToEntityType:completion:)])
{
// iOS 6 and later
[objStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error)
{
dispatch_async(dispatch_get_main_queue(), ^{
if (granted)
{
// code here for when the user allows your app to access the calendar
EKEvent *calEvent = [EKEvent eventWithEventStore:objStore];
calEvent.title = mstrTitleEvent;
calEvent.startDate = self.dateToBeSet;
calEvent.endDate = self.dateToBeSet;
calEvent.calendar = objStore.defaultCalendarForNewEvents;
EKAlarm *objAlarm = [EKAlarm alarmWithAbsoluteDate:self.dateToBeSet];
[calEvent addAlarm:objAlarm];
NSError *error;
BOOL _bStatus = [objStore saveEvent:calEvent span:EKSpanThisEvent commit:YES error:&error];
UIAlertView *alertV;
if(_bStatus)
{
alertV = [[UIAlertView alloc]initWithTitle:@"Congratulations" message:@"Saved To Calendar" delegate:nil cancelButtonTitle:@"Right On!" otherButtonTitles:nil];
[alertV show];
}
else
{
alertV = [[UIAlertView alloc]initWithTitle:@"Alert" message:[NSString stringWithFormat:@"Error saving to calendar, with error %@.",[error localizedDescription]] delegate:nil cancelButtonTitle:@"Cancel" otherButtonTitles:nil];
[alertV show];
}
}
else
{
// code here for when the user does NOT allow your app to access the calendar
UIAlertView *alertV = [[UIAlertView alloc]initWithTitle:@"Alert" message:@"Please grant access to the calendar, and try again later." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[alertV show];
}
});
}];
}
