So durchlaufen Sie API-Informationen am besten mit iOS ⇐ IOS

[Guest]

Gibt es eine einfachere Möglichkeit, Arrays/Wörterbücher zu durchlaufen, ohne viele separate NSArrays/NSDictionaries zu erstellen? Ich weiß, dass Sie verschachtelte Wörterbücher mit Punktnotation und Wert am Schlüsselpfad durchqueren können, aber was ist, wenn Arrays beteiligt sind?
Zum Beispiel:
Am Wenn ich im API-Ergebnis unten auf das Objekt unter „feed.entry.link[4].href“ zugreifen möchte, muss ich ein Array im Schlüsselpfad „feed.entry“ definieren und dann seinen ersten Eintrag als zuweisen ein Wörterbuch, definieren Sie dann ein Array unter keypath „link“ und greifen Sie darauf zu vierten Eintrag als Wörterbuch erstellen und dann auf seinen Wert unter „href“ zugreifen.
Ist das normal?
