SFSafariViewController as a ui.View

[coltonboyd]

I was wondering if any of you that are good with objc_util could help me out.

I would like to present a SFSafariViewController as a ui.View from a ui.View that is already presented.

Or be able to add SFSafariViewController as a subview for the already presented view.

Thx in advance.

@coltonboyd or

#========= SFSafariViewController to allow Safari extension in WebView

	#print('SafariViewControllerDidFinish_')
	SFSafariViewController = ObjCInstance(_controller)
	#....... still close view problems
	try:
		SFSafariViewController.uiview.close()
	except Exception as e:

def MySFSafariViewController(url, w=None, h=None, local=None, popover_location=None, reader=False):
	uiview = ui.View()
	uiview.background_color = 'white'
	if w and h:
		uiview.frame = (0,0,w,h)
		uiview.present('sheet',hide_title_bar=True)
	else:

	# SFSafariViewController only accepts http: or https:,  not file:
	# thus, in this case, we need to create a local server

	# Use new delegate class:

	SFSafariViewController.delegate = delegate		
	SFSafariViewController.setModalPresentationStyle_(3)

@cvp to clarify I am attempting to run this is the most current Xcode Template. Your code is good starting place but when I tried it was just a blank white screen. The code I am trying to incorporate is:

from objc_util import *

SFSafariViewController = ObjCClass('SFSafariViewController')

@on_main_thread
def open_in_safari_vc(url, tint_color=None):
    vc = SFSafariViewController.alloc().initWithURL_(nsurl(url))
    if tint_color is not None:
        vc.view().tintColor = tint_color
    app = UIApplication.sharedApplication()
    root_vc = app.keyWindow().rootViewController()
    root_vc.presentViewController_animated_completion_(vc, True, None)
    vc.release()

open_in_safari_vc('http://apple.com', UIColor.orangeColor())

Basically I have an ui.View called App that is presented from the point of where the iOS app starts. When clicking on a button view on this App class I want it to open a SFSafariViewController with the designated url given to the open_in_safari_vc function.

When I attempt this in the Xcode Template I get this error:

[Presentation] Attempt to present <SFSafariViewController: 0x7fbfa7a98000> on <PYAViewController: 0x7fbfa4408e80> (from <PYAViewController: 0x7fbfa4408e80>) whose view is not in the window hierarchy.

I hope this clarifies what I'm trying to do.

Also to add, I added the code above to a blank main.py file in a blank Xcode project and it worked just fine. I think it has something to do with the App ui.View that I am presenting.

@coltonboyd I can't help you with Xcode....

For anybody following this thread I figured how to present SFSafariViewController from an already presented view:

#######################################################################

# Necessary imports. 
from objc_util import *

#######################################################################

class WebView():
  @on_main_thread
  def __init__(self,url,uiview,bar_tint_color,control_tint_color):
    self.safari_view_controller = ObjCClass("SFSafariViewController").alloc().initWithURL_(nsurl(url))
    self.safari_view_controller.preferredBarTintColor = bar_tint_color
    self.safari_view_controller.preferredControlTintColor = control_tint_color
    self.view_controller = ObjCClass('UIViewController').viewControllerForView_(ObjCInstance(uiview))

  @on_main_thread  
  def present(self):
    self.view_controller.presentViewController_animated_completion_(self.safari_view_controller,True,None)

@coltonboyd sorry, I didn't correctly understood your post 🙄

@cvp it’s all good. Your code gave me a good starting place and led me to the code I got so thank you!
