there 2 ways display localized text in push notification in ios:

localize message in server

in case, must send device language server. code need add ios app similar following:

nsstring *preferredlanguage = [[nslocale preferredlanguages] objectatindex:0]; const char *langstr = [preferredlanguage utf8string]; [self sendcurrentlanguage:langstr]; // method communicates server 

then can send notification message in appropriate language using alert key in notification json payload.

send localization string notification payload

you can send localized string in payload. alert key accepts child loc-key key can use send localized string:

"alert" : {      "loc-key" : "my localized string",     ... } 

and then, in localizable.strings file inside correspondent language identifier, add following:

"my localized string" = "the localized string in language want."; 

if need pass arguments build final localized string, can pass loc-args json array in notification payload, too:

"alert" : {          "loc-key" : "my localized string",         "loc-args" : [ "first argument", "second argument" ],         ...     } 

and, in localizable.strings:

 "my localized string" = "the localized string first argument %@, , second argument %@." 

or, if need change positions:

 "my localized string" = "the localized string second argument %2$@, , first argument %1$@.";
