Adds BW::UIActivityViewController for a more Ruby-like interface to activity view controllers

[markrickert]

This is my first attempt. Some guidance on how the DSL should work would be greatly appreciated. I'll write tests once I've nailed down functionality.

Usage:

# Without a completion handler
BW::UIActivityViewController.new(
  items: "Some Text", # or ["Some Text", NSURL.URLWithString('http://www.rubymotion.com')] or a UIImage
  excluded: :add_to_reading_list
)

# With completion handler
BW::UIActivityViewController.new(
  items: "Some Text",
  excluded: [:add_to_reading_list, :print, :air_drop]
) do |activity_type, completed|
  puts "completed with activity: #{activity_type} - finished?: #{completed}"
end

Let me know if i'm on the right track here.

I just patched BW::Constants.get() so that it doesn't try and bitwise an array of strings like ["com.apple.UIKit.activity.AirDrop", "com.apple.UIKit.activity.Print"]

I suppose the next step could be to have helper methods like BW::UIActivityViewController.email() and BW::UIActivityViewController.airdrop() that only allow that one activity type.

Huh... Travis returned back this error:

  - should return an array of string constant values [ERROR: NameError - uninitialized constant Kernel::UIActivityTypeAirDrop]
NameError: uninitialized constant Kernel::UIActivityTypeAirDrop
    constants.rb:41:in `get:': .get - should return an array of string constant values

    spec.rb:329:in `run'
222 specifications (496 requirements), 0 failures, 1 errors

Wonder why, when I'm initializing those constants in the module?

[markrickert]

Any feedback on this feature @colinta, @clayallsopp or @supermarin ?

[colinta]

The API looks solid, I wonder if Travis is running an old version, and doesn't have that AirDrop constant...

[colinta]

items: "string" looks funny to me, seems like it should require an array; item: "string" would then delegate to items: [..]

[clayallsopp]

Yeah, +1 on @colinta's thoughts. seems like :items or :item should be valid options, for readability

Also editing the readme would be 👍

Travis is yelling because on OS X the Airdrop constant doesn't exist; you should do something like this in the specs:

if App.ios?
  it "should bitmask array values" do
   #...
  end
end

[markrickert]

Aha! Thanks for the tip on the tests. I'll try and get it refactored a bit and get the tests working on Travis here in the next few days. FYI, I'm using this code in production in my Textables app to display the UIActivityViewController.

[markrickert]

Is there a preferred way to accept both item and items?

something like:

items = Array(options[:items] || options[:item])

??

[clayallsopp]

Yup, that looks good to me

[markrickert]

Once Travis passes, this is good to go! Working tests: 809 specifications (1202 requirements), 0 failures, 0 errors

[markrickert]

✨ It passed :)

[clayallsopp]

Awesome - update the README as well?

[markrickert]

Done. Added it to the UI section of the readme.

[clayallsopp]

👍 most excellent, great work!

[markrickert]

Thanks! Glad to contribute!

[markrickert]

✨ YAY!
