TreasureData

Objective-C

@interface TreasureData : NSObject

Swift

class TreasureData : NSObject

The main interface for the SDK. All initialization and configuration (except retry parameters) could be done through here.

Minimal example:

 [TreasureData initializeWithApiKey:@"<your_write_only_api_key>"];

 [[TreasureData sharedInstance] addEvent:@{@"welcome": @"Hello world"}
                                database:@"my_db"
                                table:@"my_ios_events"];

 [[TreasureData sharedInstance] uploadEvents];

  • Inner client responsible for uploading events, automatically initialized. Additional parameters like request retrying could be configured here.

    Declaration

    Objective-C

    @property (nonatomic, strong) TDClient *_Nullable client;

    Swift

    var client: TDClient? { get set }

  • The destination database for events that doesn’t specify one, default is “td”.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable defaultDatabase;

    Swift

    var defaultDatabase: String? { get set }

  • The destination table for events that doesn’t specify one. Currently this also applied for automatically tracked events (if enabled): app lifecycle, IAP and audits, default is “td_ios”.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable defaultTable;

    Swift

    var defaultTable: String? { get set }

  • The host to use for the Profile API Defaults to https://cdp.in.treasuredata.com
