Question 1

How to use McPicker as a popover on iPhone?

Accepted Answer

Use the showAsPopover method with a UIView or UIBarButtonItem; McPicker overrides UIKit's default to display as a popover even on iPhone, as demonstrated in the code examples.

Question 2

McPicker vs UIPickerView: which is better?

Accepted Answer

McPicker adds animations, rotation handling, and multiple presentation styles out of the box, saving development time. However, UIPickerView is more lightweight and native, so choose McPicker for convenience but stick with UIPickerView for minimal dependencies.

Question 3

How to customize McPicker toolbar buttons?

Accepted Answer

Set custom toolbar items using McPicker.setToolbarItems with McPickerBarButtonItem instances, and adjust properties like toolbarItemsFont and toolbarButtonsColor, as shown in the customization snippet.

Question 4

Does McPicker work with SwiftUI?

Accepted Answer

No, McPicker is UIKit-based and does not directly support SwiftUI. To integrate, you must wrap it in a UIViewRepresentable, which adds complexity and may not be ideal for SwiftUI-centric projects.

Question 5

How to handle multiple components in McPicker?

Accepted Answer

Pass multiple string arrays to the data parameter; McPicker automatically creates a picker component for each array, with selections returned as a dictionary mapping component indices to strings.

Question 6

How to set default selections in McPicker?

Accepted Answer

Use the pickerSelectRowsForComponents property, a dictionary specifying which rows to select per component, e.g., [0: [3: true]] selects row 3 in component 0, as detailed in the README.
