In messaging service, when we see the Messages table then there is a column name ‘Device ID’. Are you using this code to get the device id ‘[[[UIDevice currentDevice] identifierForVendor] UUIDString]’?
Yes:
#if TARGET_OS_IPHONE || TARGET_IPHONE_SIMULATOR
UIDevice *device = [UIDevice currentDevice];
NSString *deviceId = [device.identifierForVendor UUIDString];
deviceRegistration.deviceToken = device.name;
deviceRegistration.deviceId = deviceId;
deviceRegistration.os = @"IOS";
deviceRegistration.osVersion = device.systemVersion;
#else
deviceRegistration.os = @"OSX";
NSString *deviceId = [self serialNumber];
deviceRegistration.deviceId = deviceId;
#endif
Thanks this is helpful!
