アーティスト名で検索

MPMediaPropertyPredicateを使用する。

let filter1 = MPMediaPropertyPredicate(value: "BOOWY", forProperty: MPMediaItemPropertyArtist)
let filterSet = Set([filter1])
let mPMediaQuery = MPMediaQuery(filterPredicates: filterSet)

フィルタはAnd条件

アーティスト名2つは検索が0件になる。

let filter1 = MPMediaPropertyPredicate(value: "BOOWY", forProperty: MPMediaItemPropertyArtist)
let filter2 = MPMediaPropertyPredicate(value: "sinon", forProperty: MPMediaItemPropertyArtist)
let filterSet = Set([filter1, filter2])
let mPMediaQuery = MPMediaQuery(filterPredicates: filterSet)

検索結果をアルバム単位にする

groupingTypeを指定。

let filter1 = MPMediaPropertyPredicate(value: "渡辺美里", forProperty: MPMediaItemPropertyArtist)
let filterSet = Set([filter1])
let mPMediaQuery = MPMediaQuery(filterPredicates: filterSet)
mPMediaQuery.groupingType = MPMediaGrouping.album
