iOS Question AddressBook OBJC

[narek adonts]

Hi

here is the short OBJC code to get all contacts

ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, nil);
NSArray *allContacts = (__bridge NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBookRef);

i am doing

#If OBJC
- (NSArray *) GC
{

ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, nil);
NSArray *allContacts = (__bridge NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBookRef);
return allContacts;
}


#End if



Dim jo As NativeObject = Me
Dim l As List=jo.GetField("GC")

but it doesnt work. it says [<b4i_main 0x1700f6380> valueForUndefinedKey:]: this class is not key value coding-compliant for the key GC.

how can I use native object to retunr this to a list

It is not a field. You need to call jo.RunMethod.

 

[narek adonts]

with RunMethod it is also giving an error

-[NSMethodSignature getArgumentTypeAtIndex:]: index (2) out of bounds [0, 1]

 

[Erel]

Please post the relevant code.

 

[narek adonts]

@import AddressBook;

- (NSArray *) GC
{

ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, nil);
NSArray *allContacts = (__bridge NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBookRef);
return allContacts;
}

Dim no As NativeObject = Me
Dim l As List=    no.RunMethod("GC", Array(Null))

 

[Erel]

Your code is passing a parameter to GC (with the value of null).

It should be:
no.RunMethod("GC", null)

Erel,

Please let us know if you are working on a PhoneBook Library or no to be able to know if it is worth to spend time on creating this library by ourselves.

Eventually there will be a contacts library. However it will not happen in the near future.

I have started a quick bit of work on building a Contacts class. It is just from the shell of what has been found on the internet.

I just wanted to post this here as I have not written a lib/class before and wasn't sure what I am doing is the write way to do it.

When getting the allContacts NSArray before, it returned a list of ABPerson items. I had no idea how to access them. So I have written a wrapper to turn them into something usable in B4i, but I am not sure if this is the correct way of doing things as it is double handling the data. Any one that can guide me on how it should be done I would appreciate it.

I have put an example of it in this post. https://www.b4x.com/android/forum/t...dress-book-iphone-contacts.52118/#post-327208

Oh yeah - and how much do I dislike Obj-C... This is why I am so glad Erel has provided us with B4i... I could not program in this language every day.

Feedback please?

Cheers
Brian

I have already finished the Contacts class. Will publish today. You can work on it after.

No, that's ok...

If you have already finished it then I don't need to write it. Thanks for letting me know.

Cheers
