ios - 轨道 MPMediaItem 中的专辑插图

Question

我正在使用 Apple Music API 的 recent played endpoint返回最近播放的媒体 Assets 列表。

然后我使用其中之一并在 MPMusicPlayerController 上播放它。

                "standard": "Maybe more than any other rapper in history, Lil Wayne’s output is defined by franchises. An artist should be so lucky to sustain the kind of longevity that would allow for multi-volume phases the likes of Wayne’s <i>Dedication</i>, and <i>Da Drought</i> mixtapes, let alone the series that made him into a superstar, <i>Tha Carter</i>. Though Wayne was not without projects in between, some seven years were allowed to pass between the release of the fourth and fifth installments of the lattermost. Fortunately, Wayne has rewarded his fans’ patience with 23 tracks that speak to a number of his most storied eras.<br />\n“Mixtape Weezy,” as Jay-Z famously coined, is alive and well on songs like the Swizz Beatz-produced “Uproar,” Wayne blacking out over a reinterpretation of G-Dep’s 2001 hit “Special Delivery.” The nostalgia doesn’t stop (or peak) there, as Wayne and Snoop Dogg share space over a flip of Dr. Dre’s “Xxplosive” on “Dope N*ggaz,” while Mannie Fresh revisits the Cash Money golden-era bounce of Juvenile’s “Ghetto Children” for “Start This Shit Off Right.” There are nods to the experimental Wayne of the <i>I Am Not A Human Being</i> projects (“Don’t Cry,” “Mess”) and also the rapper’s under-heralded pop wizardry (“Famous,” which features his daughter Reginae as hook singer), and even a love song built on a gospel sample, “Dope New Gospel.” In all, <i>Tha Carter V</i> is an album for anyone who’s missed Wayne—no matter which Wayne they’d missed.",

    },

每当我想访问当前正在播放的内容的元数据时，我都可以使用 nowPlayingItem 获取它。返回专辑中当前轨道的 MPMediaItem 的属性。

此 MPMediaItem 的艺术作品属性为空，因此我想访问专辑的艺术作品。我可以获得 albumPersistentStoreId(例如 3911653000682848550)，我正在使用它通过 Apple Music API 请求专辑信息:

https://api.music.apple.com/v1/catalog/us/albums/3911653000682848550

但这会返回“未找到资源”错误消息。

使用搜索端点 ( https://api.music.apple.com/v1/catalog/us/search?term=the+carter+v&limit=2&types=artists,albums ) 或最近播放的原始端点，我发现其中返回的专辑 ID 与我在 albumPersistentStoreId 属性中获得的不同。如何从 MPMediaItem 获取正确的专辑 ID？

Answer 1

您可以使用 MPMediaItem 的 playbackstoreID - 从 API 请求轨道信息并从那里获取专辑封面。
