Ich erstelle Musik-App. Die Anwendung muss Informationen über Track, Album und Künstler abrufen. Zeigt derzeit diese atm. Ich benutze The Last FM. Ich möchte jedoch hinzufügen Spotify, so dass es Track zum Abspielen abrufen kann.Spotify Api: Wie man Spotify "Preview Track" zur letzten FM-App in Objective C hinzufügt
Ich bin auf der Suche nach einer Vorschau des Tracks, wenn der Benutzer auf den Track auf der App klickt, klicken Sie auf Play und es spielt den Song (Vorschau). Ich möchte einen anderen Xib öffnen, der eine Vorschau des Songs haben wird. Ich habe den Code für meine Anwendung bereitgestellt. Screenshot, um zu zeigen, wie es fließt.
Dies ist meine erste Anwendung, bitte Ich habe keine Ahnung, wie Spotify integriert werden soll uch schätze jeden, der helfen kann.
Letzte Fm Album, Track und Artist Info Suche.
