Set custom push rules

If a user is logged in on multiple platforms, the user can configure custom push rules to specify the platforms that can or cannot receive offline push notifications.

Prerequisites

Before you implement the custom push rule feature, make sure that the following conditions are met:

Procedure

Notification for offline push rule update

To receive the notification for custom rule update, register the ZIMEventHandler delegate callback and listen for userRuleUpdated.

Untitled
// Listen for the user rule change.
zim.on('userRuleUpdated', (zim, data) => {
    // get the offline push rule
    const offlinePushRule = data.userRule.offlinePushRule;
});

Set offline push rules

To support custom push rules, build the ZIMUserOfflinePushRule class to specify the platforms that do not receive offline push notifications (notToReceiveOfflinePushPlatforms) when the user is online on specified platforms (onlinePlatforms).

To set the above rules, call the updateUserOfflinePushRule method.

Untitled
// Set offline push rules.

var offlinePushRule = {
    // The user logs in on Windows, macOS, and Linux platforms.
    onlinePlatforms: [1, 4, 5],
    // The user does not receive offline push on iPhoneOS, iPadOS.
    notToReceiveOfflinePushPlatforms: [2, 3, 9],
};

zim.updateUserOfflinePushRule(offlinePushRule)
    .then((res) => {
        // success
    })
    .catch((err) => {
        // error
    });

Query custom push rules

Call the querySelfUserInfo method to obtain custom offline push rules from the selfUserInfo.userRule.offlinePushRule field in the callback.

Untitled
zim.querySelfUserInfo().then((res) => {
    const { offlinePushRule } = res.selfUserInfo.userRule;
});
