iOS14 UUID KeyChain DeviceInfo IDFA UDID

XYUUID

English | 简体中文

Installation

CocoaPods:

• pod'XYUUID'

Manual integration:

• Copy the XYUUID folder to your project

Background

• Starting from iOS 10, IDFA may be restricted by users from ad tracking, resulting in the inability to obtain IDFA normally, thus making it impossible to use IDFA as a unique device identifier

Advantages of XYUUID

• Simple API
• Use the latest iOS 14 API to get IDFA
• Universally unique identifiers with different persistence levels

Advantages of uuidForDevice

• onger timeliness
• Long storage
• Lower conflict rate
• Lower drift rate

API

Get UUIDs of different persistence levels

/// Random UUID, this value will be refreshed every time
+ (NSString *)uuid;

/// Install UUID, this value will be refreshed every time you reinstall
+ (NSString *)uuidForInstall;

/// Open the application UUID, this value will be refreshed every time the application is opened
+ (NSString *)uuidForAppOpen;

/// IDFA, open and close authorization, this value will be refreshed
+ (NSString *)uuidForIDFA;

/// IDFV
+ (NSString *)uuidForIDFV;

/// Device information UUID, generated according to device information, can remain unchanged for a period of time
+ (NSString *)uuidForDeviceInfo;

/// Keychain UUID, uninstall application remains unchanged
+ (NSString *)uuidForKeychain;

/// Device UUID, the unique identifier of the device
+ (NSString *)uuidForDevice;
