On iOS I could three steps:
1. tap dropdown to select
2. scroll list
3. tap 'Done'
But with any list of significant length (the reason you would use a dropdown in the first place) you'll probably need a few actions to scroll to the right item.

None of the options he shows in the article works well there.
This happens to me far more frequently than I would like. :)
And mostly for very significant length (e.g. "all my songs") E.g. for up to 20-30 items dropdown is still better, and you can select with one finger without much concetration.
Of course there's also the "searchable dropdown", or a dropdown where you can type the first letter(s) of an options to jump there.
