Bug report

CHECKLIST

• I have read the issue reporting guidelines

• I confirm this is a suspected bug or issue that will affect other users

• I have reproduced the issue using the example project or provided the necessary information to reproduce the issue.

• I have read the documentation thoroughly and it does not help solve my issue.

• I have checked that no similar issues (open or closed) already exist.

Current behavior:

1. Call requestCalendarAuthorization() on iOS 17.
2. OS dialog does not appear.
3. The successCallback consistently returns DENIED_ALWAYS.

Expected behavior:

Before granting calendar permission, the OS dialog should appear, and the response in the successCallback should vary based on the user's selection.

Steps to reproduce:

Same as described above.

@yudateNoriyuki Have you found any solution?

@aks7665
Yes, I was able to solve it using ChatGPT, although not perfectly.
I resolved it by modifying the following part of src/ios/Diagnostic_Calendar.m:

Before

[self.eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
    [diagnostic logDebug:[NSString stringWithFormat:@"Access request to calendar events: %d", granted]];
    [diagnostic sendPluginResultBool:granted:command];
}];

After

if (@available(iOS 17, *)) {
    [self.eventStore requestFullAccessToEventsWithCompletion:^(BOOL granted, NSError *error) {
        [diagnostic logDebug:[NSString stringWithFormat:@"Access request to calendar events: %d", granted]];
        [diagnostic sendPluginResultBool:granted:command];
    }];
} else {
    [self.eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
        [diagnostic logDebug:[NSString stringWithFormat:@"Access request to calendar events: %d", granted]];
        [diagnostic sendPluginResultBool:granted:command];
    }];
}

This allows requesting full access to calendar permissions.
However, please note that if you're using https://github.com/EddyVerbruggen/Calendar-PhoneGap-Plugin, this modification alone won't enable you to add events to the calendar. Be cautious about that.
