2. Activity types
The range of actions available to a user within the sharing interface are defined by activity types. These pre-defined or custom actions determine how shared content can be manipulated or distributed. Properly configuring these types is crucial for an efficient user experience.
-
System-Provided Activities
The system offers a default set of activity types such as copying, printing, saving to files, and sharing via messaging or social media. These built-in options provide a standard level of functionality across various applications. For example, enabling the “UIActivityTypeCopyToPasteboard” allows users to quickly copy text or images for use in other applications. This leverages the existing system infrastructure for common tasks, reducing development effort.
-
Application Activities
Applications can declare their own activity types to offer unique functionality related to their specific data types or services. For instance, a document editing application could define an activity type to directly “Open in [Application Name]”. This allows users to seamlessly transfer data between applications, enhancing interoperability and workflow efficiency. By creating specialized activities, applications can offer a richer, more integrated sharing experience.
-
Exclusion of Activity Types
It is possible to exclude specific activity types from appearing in the sharing interface based on the context of the data being shared or the desired user experience. For example, it might be appropriate to exclude the “UIActivityTypePrint” option when sharing a small text snippet. This fine-grained control allows developers to tailor the available options to the users needs, preventing clutter and streamlining the sharing process.
-
Custom Activities
Developers can create custom actions tailored for their application. This allows the integration of unique services or workflows not covered by system-provided activities. For instance, an application might offer a “Publish to Company Intranet” action, specific to internal company systems. These custom options expand the utility of sharing feature, integrating it deeply within the application ecosystem.

Conversely, sharing an image may necessitate excluding actions that are strictly text-based, like “Add to Reading List.” Properly configuring exclusion options based on content type ensures that only the most relevant actions are presented.
-
Application-Specific Functionality
Certain actions might be redundant or conflict with an application’s own capabilities. If an application has its own built-in mechanism for saving files to a specific location, the system-provided “Save to Files” action may be unnecessary. Exclusion options provide the means to suppress this duplicate functionality, maintaining consistency within the application’s user interface. This also prevents user confusion arising from multiple pathways to the same outcome.
-
User Role or Permissions
In enterprise environments or applications with role-based access control, certain sharing actions might be restricted based on the user’s permissions. Exclusion options facilitate the implementation of these restrictions, preventing unauthorized sharing or data leakage. For instance, users with limited permissions may be prohibited from sharing confidential documents externally. By dynamically adjusting the visible actions based on user roles, applications can enforce data security policies.
-
Contextual Awareness
The current state of the application or device may influence the suitability of certain sharing actions. If the device is offline, actions that require a network connection, such as sharing to a cloud service, should be excluded to avoid unnecessary error messages or user frustration. Exclusion options, when combined with runtime checks for device status, enable applications to adapt the sharing interface to the current context, providing a more seamless and intuitive experience.
Effective utilization of exclusion options is critical for tailoring the system sharing mechanism to meet the specific needs of both the content being shared and the application itself. By selectively hiding irrelevant or inappropriate actions, developers can create a cleaner, more focused interface that improves user efficiency and prevents potential errors. This level of control ensures that the system sharing feature remains a valuable asset, enhancing the overall user experience without adding unnecessary complexity.
4. Completion handling
Completion handling represents a crucial aspect of implementing the system’s standard sharing mechanism, providing developers with a mechanism to react to the user’s selection and the outcome of a sharing operation. This functionality allows for appropriate actions to be taken following the user’s interaction, such as updating the application’s state, providing feedback to the user, or handling errors encountered during the sharing process.
