@DavinE, so, if I understand correctly, you presented another view with wait_modal, and some scripter script did not work. One reason for that could be that the wait_modal probably stops the update cycle of the view at the bottom, and thus all scripter scripts as well.

If so, and you want to keep the wait_modal, there is an easy workaround - you can start_scripter for the modal view, and then for the old root view again after the modal view is dismissed.

Thanks to Noah Gilmore, we have a convenient up-to-date list of the available symbols to use with for example the button pop-up menus. I updated the browser and moved the package under the ui3 umbrella.

See the simple usage docs here.

@ihf, what I meant was that I think this is a missing feature by Apple, and putting in a feature request to Apple might not be a bad idea.

@frakman1, here’s a reusable version, with usage sample in the end. Note the option to provide a callback if you want control the closing of the message composer.

import objc_util


objc_util.load_framework('MessageUI')


MFMessageComposeViewController = objc_util.ObjCClass(
    'MFMessageComposeViewController')
SUIViewController = objc_util.ObjCClass('SUIViewController')


CANCEL, SEND, FAIL = range(3)

def default_callback(result):
    if result == FAIL:
        return True

def messageComposeViewController_didFinishWithResult_(
    _self, _cmd, _controller, _result):
    """
    Required to be able to dismiss the controller.
    """
    controller = objc_util.ObjCInstance(_controller)
    
    # 0 is returned as None
    result = _result or 0
    
    # Stay in the composer if callback returns True
    if controller.callback and controller.callback(result):
        return
    else:
        controller.dismissViewControllerAnimated_completion_(True, None)
        
    
MessageSenderDelegate = objc_util.create_objc_class(
    'MessageSenderDelegate',
    methods=[
        messageComposeViewController_didFinishWithResult_,
    ],
    protocols=['MFMessageComposeViewControllerDelegate']
)
    

def send_message(
    superview, to='', body='',
    callback=None
):
    """
    Open a message composer with the
    recipient and message already filled.
    Optional callback gets the result of the

    """
    composer = MFMessageComposeViewController.alloc().init()
    composer.setRecipients_(['12345678'])
    composer.setBody_('Message content')
    
    composer.callback = callback or default_callback

    delegate = MessageSenderDelegate.alloc().init()
    composer.messageComposeDelegate = delegate
    
    vc = SUIViewController.viewControllerForView_(
        superview.objc_instance)
    vc.presentModalViewController_animated_(composer, True)


if __name__ == '__main__':
    
    import ui
    
    v = ui.View()
    b = ui.Button(
        tint_color='white',
        flex='TBLR',
    )
    
    if MFMessageComposeViewController.canSendText():
        b.title = 'Send Message'
        b.background_color = '#0e45cd'
    else:
        b.title = 'No messaging available'
        b.background_color = '#c35757'
        b.enabled = False
    
    b.size_to_fit()
    b.frame = b.frame.inset(-8,-8)
    b.center = v.bounds.center()

    def send_message_action(sender):
        send_message(sender.superview, to='1234566', body='Message')
        
    b.action = send_message_action
    
    v.add_subview(b)
    v.present('fullscreen')

Ok, you need to set the messageComposeDelegate instead of delegate, which is for the inherited UINavigationViewController. Will post a working version later today.

Via printing to file I think I have confirmed that the delegate method is not reached at all, but cannot see why.

Very annoying that I seem to remember we have done this before, but can’t find the post.

@cvp, hmm, but shouldn’t iPads have iMessage, even if no SMS?

Here’s a version that checks for availability:

import objc_util
import ui


objc_util.load_framework('MessageUI')


MFMessageComposeViewController = objc_util.ObjCClass(
    'MFMessageComposeViewController')
SUIViewController = objc_util.ObjCClass('SUIViewController')


v = ui.View()
b = ui.Button(
    tint_color='white',
    flex='TBLR',
)

if MFMessageComposeViewController.canSendText():
    b.title = 'Send Message'
    b.background_color = '#0e45cd'
else:
    b.title = 'No messaging available'
    b.background_color = '#c35757'
    b.enabled = False

b.size_to_fit()
b.frame = b.frame.inset(-8,-8)
b.center = v.bounds.center()

RESULTS = ('Cancelled', 'Sent', 'Failed')

def messageComposeViewController_didFinishWithResult_(
    _self, _cmd, _controller, _result):
    """
    Required to be able to dismiss the controller.
    """
    controller = objc_util.ObjCInstance(_controller)
    #result = objc_util.ObjCInstance(_result)
    #print(RESULTS[result])
    
    controller.dismissModalViewControllerAnimated_completion_(True, None)
    
    
MessageSenderDelegate = objc_util.create_objc_class(
    'MessageSenderDelegate',
    methods=[
        messageComposeViewController_didFinishWithResult_,
    ],
    protocols=['MFMessageComposeViewControllerDelegate']
)


def send_sms(sender):
    composer = MFMessageComposeViewController.alloc().init()
    composer.setRecipients_(['12345678'])
    composer.setBody_('Message content')
    
    delegate = MessageSenderDelegate.alloc().init()
    composer.setDelegate_(delegate)
    
    vc = SUIViewController.viewControllerForView_(
        sender.superview.objc_instance)
    vc.presentModalViewController_animated_(composer, True)

b.action = send_sms

v.add_subview(b)
v.present('fullscreen')

@cvp, thanks for trying.

@frakman1, this is how far I quickly got, but frustratingly I do not seem to get the sending UI dismissed, so it is unusable right now.

b = ui.Button(
    title='Send SMS',
    background_color='#0e45cd',
    tint_color='white',
    flex='TBLR',
)
b.frame = b.frame.inset(-8,-8)
b.center = v.bounds.center()


RESULTS = ('Cancelled', 'Sent', 'Failed')

def messageComposeViewController_didFinishWithResult_(
    _self, _cmd, _controller, _result):

    controller = objc_util.ObjCInstance(_controller)
    #result = objc_util.ObjCInstance(_result)
    #print(RESULTS[result])
    
    controller.dismissModalViewControllerAnimated_completion_(True, None)
