Monitor Database Upgrade Status

Starting from version 5.10.4, the SDK provides the RCDatabaseStatusDelegate protocol to monitor changes in the database upgrade status.

When calling the SDK connection interface, a database upgrade operation may be triggered. If the data volume is large, this process can be time-consuming. By monitoring the database upgrade status, the app can handle different business logic or provide prompts on the page.

Database Upgrade Status Delegate Protocol

The RCDatabaseStatusDelegate protocol is as follows:

@protocol RCDatabaseStatusDelegate <NSObject>

/*!
 Database upgrade will start

 - Since: 5.10.4
 */
- (void)databaseUpgradeWillStart;

/*!
 Database upgrade completed

 - Since: 5.10.4
 */
- (void)databaseUpgradeDidComplete:(RCErrorCode)code;

/*!
 Database upgrade in progress
 
 - Parameter progress: Upgrade progress 【0-100】
 - Since: 5.10.4
 */
- (void)databaseIsUpgrading:(int)progress;
@end

Add or Remove Delegate

Set the database status listener, which supports multiple listeners.

To avoid memory leaks, remove the delegate when it is no longer needed.

// Add delegate
[[RCCoreClient sharedCoreClient] addDatabaseStatusDelegate:self];

// Remove delegate    
[[RCCoreClient sharedCoreClient] removeDatabaseStatusDelegate:self];
