iOS Question Problem GetField NativeObject

mayahandayani · Jun 13, 2024

Hello...
I'm using NativeObject to CalendarEvent like this

For Each e As CalendarEvent In Events
     Private no As NativeObject = e
Next

when I log the "no", the result like this :

Code: Copy

<B4INativeObject: EKEvent <0x28348d080>
[<EKEvent 0x280780160> valueForUndefinedKey:]: this class is not key value coding-compliant for the key recurrence.
{
     EKEvent <0x28348d080>
{     title =         test;
     location =     (null);
     calendar =     EKCalendar <0x2816d1580> {title = [email protected]; type = CalDAV; allowsModify = YES; color = #CCA6ACFF;};
     alarms =         (
    "EKAlarm <0x2816d1300> {triggerInterval = -1800.000000}"
);
     URL =             (null);
     lastModified = 2024-05-28 7:19:11 AM +0000;
     startTimeZone =     Asia/Jakarta (GMT+7) offset 25200;
     endTimeZone =     Asia/Jakarta (GMT+7) offset 25200
};
     location =     (null);
     structuredLocation =     (null);
     startDate =     2024-06-05 5:00:00 AM +0000;
     endDate =         2024-06-05 6:00:00 AM +0000;
     allDay =         0;
     floating =     0;
     recurrence =     EKRecurrenceRule <0x2820ab0c0> RRULE FREQ=DAILY;INTERVAL=3;COUNT=5;
     travelTime =     (null);
     startLocation =     (null);
};>

Actually, I want to get all field like location, recurrence, etc
but when I try to GetField "recurrence" like this

B4X: Copy

Private recurrence As NativeObject = no.GetField("recurrence")

I get error like this

Code: Copy

Error occurred on line: 322 (B4XMainPage)

The property name is: https://developer.apple.com/documen...daritem/1507135-recurrencerules?language=objc

It will return a List.

Hi Erel! Thank you for your support..

Now I'm trying to add event with recurrencerule

B4X: Copy

Dim ev As CalendarEvent = store.CreateEvent
Dim newEvent As NativeObject = ev

Dim recurrenceRule As NativeObject
recurrenceRule.Initialize("EKRecurrenceRule")
recurrenceRule.RunMethod("initRecurrenceWithFrequency:interval:end:", Array(1, 2, CreateRecurrenceEnd(5)))
Dim recurrenceRules As List
recurrenceRules.Initialize
recurrenceRules.Add(recurrenceRule)
newEvent.SetField("recurrenceRules", recurrenceRules)

B4X: Copy

Sub CreateRecurrenceEnd(count As Int) As NativeObject
    Dim recurrenceEnd As NativeObject
    recurrenceEnd.Initialize("EKRecurrenceEnd")
    recurrenceEnd = recurrenceEnd.RunMethod("recurrenceEndWithOccurrenceCount:", Array(count))
    Return recurrenceEnd
End Sub

but I've got error like this

Code: Copy

Code: Copy

Dim recurrenceRule As NativeObject
recurrenceRule = recurrenceRule.Initialize("EKRecurrenceRule").RunMethod("alloc", Null)
recurrenceRule.RunMethod("initRecurrenceWithFrequency:interval:end:", Array(1, 2, CreateRecurrenceEnd(5)))

The method signature starts with a minus sign: https://developer.apple.com/documen...273-initrecurrencewithfrequency?language=objc
This means that it is an instance method, not a class method.
To create an instance you need to call the "alloc" method.

Hi Erel!
Thank you for your advice

I've tried it but the error is still same like on my previously reply, so I just add RunMethod("init",Null) and my code like this

B4X: Copy

Dim recurrenceRule As NativeObject
recurrenceRule.Initialize("EKRecurrenceRule").RunMethod("alloc", Null).RunMethod("init",Null).RunMethod("initRecurrenceWithFrequency:interval:end:", Array(0, 2, CreateRecurrenceEnd(5)))
Dim recurrenceRules As List
recurrenceRules.Initialize
recurrenceRules.Add(recurrenceRule)
newEvent.SetField("recurrenceRules", recurrenceRules)

but I've got error on line
newEvent.SetField("recurrenceRules", recurrenceRules)

the error is

B4X: Copy

Error occurred on line: 919 (pageInputJadwal)

Note : log from recurrenceRules is

B4X: Copy

recurrenceRules : <B4IList: (

)>

Any idea to fix that?
Thanks

This code works:

Code: Copy

Dim recurrenceRule As NativeObject
recurrenceRule = recurrenceRule.Initialize("EKRecurrenceRule").RunMethod("alloc", Null)
recurrenceRule.RunMethod("initRecurrenceWithFrequency:interval:end:", Array(1, 2, CreateRecurrenceEnd(5)))

Hi Erel! Thank you so much, it works!

but I have one question about invitees
I want add some emails & my code like this

B4X: Copy

Dim attendee As NativeObject
attendee.Initialize("EKParticipant")
Dim url As NativeObject
url.Initialize("NSURL")
url = url.RunMethod("URLWithString:", Array("mailto:" & "[email protected]"))
Dim attend As List
attend.Initialize
attend.Add(url)
attendee.SetField("URL", attend)          
newEvent.SetField("attendees", Array(attendee))

and I've got error like this

B4X: Copy

[<EKParticipant 0x1f64fca80> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key URL.

what's wrong?
thanks
