Contacts API - Group Modification

@cvp Could you give me an example to assign values?

Could you give me an example to assign values?

Sorry, I don't understand: assign values to what?

ccc

Like setting a person's first name, last name, email address, mobile phone number, country, etc?
Reading a value vs. writing a value.

cvp

@osamu thanks @ccc for his help

Here, a sample to create a contact with his photo

# https://forum.omz-software.com/topic/2734/contacts-module-access-profile-picture/4
from objc_util import *
import photos
	
# Load classes we need from Contacts.framework:
NSBundle.bundleWithPath_('/System/Library/Frameworks/Contacts.framework').load()

def main():
	CNContactStore = ObjCClass('CNContactStore').alloc().init().autorelease()
	
	Containers = CNContactStore.containersMatchingPredicate_error_(None,None)
	for Container in Containers:
		containerId = Container.identifier()
		break						# get first container
		
	all_assets =photos.get_assets()
	asset = photos.pick_asset(assets=all_assets)
	img_data_bytes = asset.get_image_data().getvalue()
	
	CNMutableContact = ObjCClass('CNMutableContact').alloc().init()
	CNMutableContact.firstName = 'aaTest'	# just to be the first
	CNMutableContact.imageData = img_data_bytes
	#CNMutableContact.phoneNumbers = ['123','456']
	print(dir(CNMutableContact))
	#return
	
	CNSaveRequest = ObjCClass('CNSaveRequest').new().autorelease()
	CNSaveRequest.addContact_toContainerWithIdentifier_(CNMutableContact, containerId)
	CNContactStore.executeSaveRequest_error_(CNSaveRequest, None)

if __name__ == '__main__':
	main()

@cvp Sorry, I’d like to know how to assign values to ‘date’ field of contact person.

JonB

You should take a look at the CNMutableContact created here, and you may be able to figure it out.

There should be an attributes dates, which according to the objc docs is an array of CNLabeledValue objects, where the value is an NSDate.

You can create NSDate using

dateobj=ObjCClass('NSDate').dateWithTimeIntervalSince1970_(time.mktime(time.strptime('2017-06-18', '%Y-%m-%d')))

CNLabeledValue=ObjCClass('CNLabeledValue')
value=CNLabeledValue.alloc().init()
value.label='birthday'
value.value=dateobj

Then you ought to be able to use

CNMutableContact.dates=[value]

cvp

As I didn't know which field you want to set, I let a print(dir(CNMutableContact)) in my script, so you could find your-self the name of the field..
But now, as @JonB did the job, all is good so

cvp

@JonB CNLabeledValue has to be initialized differently

	CNLabeledValue=ObjCClass('CNLabeledValue')
	value=CNLabeledValue.alloc()
	value.initWithLabel_value_('birthday',dateobj)

But date has to be a NSDateComponents

The app was terminated due to an Objective-C exception. Details below:

2021-02-02 23:04:50.219269
Labeled value <CNLabeledValue: 0x283090580: identifier=87E927A0-ED12-4AC9-89A8-EE6CCC75441D, label=birthday, value=2017-06-17 22:00:00 +0000, iOSLegacyIdentifier=-1> value 2017-06-17 22:00:00 +0000 has incorrect type __NSTaggedDate. It should be NSDateComponents.

cvp

That works

	dateComponents = ObjCClass('NSDateComponents').alloc().init()
	dateComponents.day = 4
	dateComponents.month = 5
	dateComponents.year = 2017

	CNLabeledValue=ObjCClass('CNLabeledValue')
	value=CNLabeledValue.alloc()
	value.initWithLabel_value_('birthday',dateComponents)
	print(dir(CNLabeledValue))
	CNMutableContact.dates=[value]

@cvp @JonB
Thank you folks.
I'm just a Python beginner and I had no place to begin w/ Objective C stuff. Now I think I can begin to try.

Now I’m trying to modify and save ‘dates’ field of an existing contact. Though the following script doesn’t spit errors but nothing happens to the contact. Could anybody help?

from objc_util import *

# ObjectiveC contacts
CNContactStore = ObjCClass('CNContactStore').alloc().init()
CNContact = ObjCClass('CNContact')
Containers = CNContactStore.containersMatchingPredicate_error_(None,None)
for Container in Containers:
	id = Container.identifier()
	predicate = CNContact.predicateForContactsInContainerWithIdentifier_(id)
	# keys not exactly like in Apple doc
	predicate_contacts = CNContactStore.unifiedContactsMatchingPredicate_keysToFetch_error_(predicate, ['familyName', 'givenName', 'middleName', 'dates'], None)
	'''
	print('First name: ', end='')
	first_name = input()
	print('Last name: ', end='')
	last_name = input()
	'''
	first_name = 'Ludwig'
	last_name = 'Beethoven'
	for contact in predicate_contacts:
		if first_name == str(contact.givenName()) and last_name == str(contact.familyName()):
			break
	CNMutableContact = contact.mutableCopy()
	dateComponents = ObjCClass('NSDateComponents').alloc().init()
	label = 'passing'
	dateComponents.day = 26
	dateComponents.month = 3
	dateComponents.year = 1827
	'''
	print('Label: ', end='')
	label = input()
	print(label.capitalize()+' year: ', end='')
	dateComponents.year = int(input())
	print(label.capitalize()+' month: ', end='')
	dateComponents.month = int(input())
	print(label.capitalize()+' day: ', end='')
	dateComponents.day = int(input())
	'''
	CNLabeledValue=ObjCClass('CNLabeledValue')
	value=CNLabeledValue.alloc()
	value.initWithLabel_value_(label, dateComponents)
	CNMutableContact.dates=[value]

	CNSaveRequest = ObjCClass('CNSaveRequest').new().autorelease()
	CNSaveRequest.updateContainer_(CNMutableContact)
	CNContactStore.executeSaveRequest_error_(CNSaveRequest, None) ```

cvp

@osamu this works

	CNSaveRequest = ObjCClass('CNSaveRequest').new().autorelease()
	CNSaveRequest.addContact_toContainerWithIdentifier_(CNMutableContact, containerId)
	CNContactStore.executeSaveRequest_error_(CNSaveRequest, None)

if __name__ == '__main__':
	main()

Wrong: CNSaveRequest.updateContainer_(CNMutableContact)
Correct: CNSaveRequest.updateContact(CNMutableContact)

Console:
First name: Ludwig
Last name: Beethoven
Label: passing
Passing year: 1827
Passing month: 3
Passing day: 26

Final code:

from objc_util import *

# ObjectiveC contacts
CNContactStore = ObjCClass('CNContactStore').alloc().init()
CNContact = ObjCClass('CNContact')
Containers = CNContactStore.containersMatchingPredicate_error_(None,None)
for Container in Containers:
	id = Container.identifier()
	predicate = CNContact.predicateForContactsInContainerWithIdentifier_(id)
	# keys not exactly like in Apple doc
	predicate_contacts = CNContactStore.unifiedContactsMatchingPredicate_keysToFetch_error_(predicate, ['familyName', 'givenName', 'middleName', 'dates'], None)
	print('First name: ', end='')
	first_name = input()
	print('Last name: ', end='')
	last_name = input()
	for contact in predicate_contacts:
		if first_name == str(contact.givenName()) and last_name == str(contact.familyName()):
			break

CNMutableContact = contact.mutableCopy()
dateComponents = ObjCClass('NSDateComponents').alloc().init()
print('Label: ', end='')
label = input()
print(label.capitalize()+' year: ', end='')
dateComponents.year = int(input())
print(label.capitalize()+' month: ', end='')
dateComponents.month = int(input())
print(label.capitalize()+' day: ', end='')
dateComponents.day = int(input())
CNLabeledValue=ObjCClass('CNLabeledValue')
value=CNLabeledValue.alloc()
value.initWithLabel_value_(label, dateComponents)
CNMutableContact.dates=[value]
CNSaveRequest = ObjCClass('CNSaveRequest').new().autorelease()
CNSaveRequest.updateContact(CNMutableContact)
CNContactStore.executeSaveRequest_error_(CNSaveRequest, None)

I couldn’t attach the capture 😣

@osamu you can also see this
