User Messaging Platform (UMP) SDK memungkinkan Anda menampilkan
pesan IDFA
kepada pengguna sebelum meminta izin mereka untuk
App Tracking Transparency
(ATT). Pesan IDFA menunjukkan kepada pengguna cara aplikasi Anda menggunakan ID.
Panduan ini membahas cara menggunakan UMP SDK untuk menampilkan pesan IDFA.
Prasyarat
Sebelum memulai, pastikan Anda telah melakukan hal berikut:
Perbarui Info.plist
Untuk menampilkan pesan pemberitahuan kustom, lakukan hal berikut:
- Buka file
Info.plist.
- Tambahkan kunci
NSUserTrackingUsageDescription dengan pesan kustom yang menjelaskan penggunaan:
<key>NSUserTrackingUsageDescription</key>
<string>This identifier will be used to deliver personalized ads to you.</string>
Deskripsi penggunaan muncul sebagai bagian dari pemberitahuan ATT IDFA saat Anda menampilkan
formulir izin:
Kemudian, hubungkan framework AppTrackingTransparency:
Kemudian, aplikasi Anda akan menampilkan pesan IDFA sebelum pemberitahuan ATT.
Pengujian
Saat menguji, ingatlah bahwa pemberitahuan ATT hanya muncul satu kali karena
requestTrackingAuthorization
adalah permintaan satu kali. UMP SDK hanya memiliki formulir yang tersedia untuk dimuat jika status otorisasi adalah
ATTrackingManagerAuthorizationStatusNotDetermined.
Agar pemberitahuan muncul untuk kedua kalinya, Anda harus meng-uninstal dan menginstal ulang aplikasi di perangkat pengujian.
Meminta iklan dengan atau tanpa IDFA
Jika pengguna menolak ATT, terus minta iklan menggunakan API format iklan Anda. Google Mobile Ads SDK tidak mengirimkan IDFA dalam permintaan iklan. Untuk mengetahui detail selengkapnya, lihat artikel Memilih format iklan.
