McPicker is a UIPickerView drop-in solution with animations that is rotation ready. The more string arrays you pass, the more picker components you'll get. You can set custom label or use the defaults. McPicker can be presented as a Popover on iPhone or iPad using showAsPopover
, as an inputView
using McTextField
or use the default slide up and down style show
.
showAsPopover
can be used to display from a UIView
or UIBarButtonItem
. showAsPopover
will always be presented as a Popover, even when used on an iPhone.
To run the example project, clone the repo, and run pod install
from the Example directory first.

McPicker's doneHandler
passes back selections: [Int : String]
as an argument. This is as simple as [<Component Index>: <String of Selection>]
from the data
you've passed in.
