How to use CZPicker in a Swift iOS app?

Since CZPicker is written in Objective-C, you need to add a bridging header to your Swift project. Import CZPicker in the header and follow the Swift demo project in the repo, which shows basic integration steps.

CZPicker vs ActionSheetPicker: which is better for iOS?

CZPicker offers a modal popup style with extensive color customization, while ActionSheetPicker provides more native action sheet integration and might have better maintenance. Choose CZPicker if you need a highly themed, standalone picker; otherwise, ActionSheetPicker could be more versatile.

Does CZPicker support dark mode in iOS 13 and later?

No, CZPicker was last updated in 2016 and doesn't include built-in support for iOS dark mode. You'd need to manually adjust colors using its customization properties, but this may not fully align with system themes.

How to customize the animation duration in CZPicker?

Set the animationDuration property on the CZPickerView instance, as mentioned in the README's customization section. This allows control over how quickly the picker appears and disappears for smoother UX.

Is CZPicker still maintained in 2024?

No, the GitHub repo shows no activity since 2016, with the last release being v0.4.3. It's effectively unmaintained, so consider alternatives for projects requiring ongoing support.

Can CZPicker handle large lists efficiently?

It uses UITableView-like dataSource methods, so performance depends on your implementation. However, it lacks built-in optimizations like cell reuse beyond standard iOS patterns, so large datasets might require manual handling.

Use Cases

Best For

Adding a modal item selector in Objective-C iOS apps
Implementing customizable single or multi-select picker interfaces
Quickly integrating a popup selection dialog with minimal code
Projects requiring a lightweight, CocoaPods-based UI component
Apps needing a themable picker view that matches design systems

Not Ideal For

Swift-only iOS projects without Objective-C interoperability setup
Apps requiring support for iOS 13+ features like dark mode or SwiftUI
Teams needing a library with active maintenance and regular updates
Projects that require advanced picker features like search or hierarchical sections

Pros & Cons

Pros

Extensive Customization Options

The README lists over 10 properties for customizing colors, buttons, and behaviors, such as headerBackgroundColor and confirmButtonHighlightedColor, allowing precise theming to match app designs.

Familiar iOS Patterns

It uses standard delegate and dataSource protocols (e.g., czpickerView:didConfirmWithItemAtRow:), making integration intuitive for developers experienced with iOS UIKit patterns.

Flexible Selection Modes

Supports both single and multiple selections with configurable options like allowMultipleSelection and needFooterView, as detailed in the customization section.

Lightweight and Simple

Focuses on core picker functionality without bloat, aligning with its philosophy of providing a reusable component that avoids building custom modals from scratch.

Cons

Outdated and Unmaintained

The last update was in 2016 (v0.4.3), so it lacks support for modern iOS versions, features like dark mode, and may have unresolved bugs or compatibility issues.

Objective-C Exclusive

Designed primarily for Objective-C, requiring bridging headers or extra setup for Swift projects, as noted in the README's separate Swift demo, which adds complexity.

Limited Advanced Features

Missing functionalities common in newer pickers, such as search bars, grouped sections, or dynamic data handling beyond basic reloadData, limiting its use for complex UIs.
