曲目 MPMediaItem 中的专辑插图

Question

我正在使用 Apple Music API 的 recent played endpoint，其中 returns 最近播放的媒体资产列表。

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

            "editorialNotes": {
                "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.",
                "short": "Weezy F Baby, and the F is for finally."
            },
            "contentRating": "explicit"
        }
    },

每当我想访问当前正在播放的内容的元数据时，我可以使用 nowPlayingItem 属性获取它，其中 returns 专辑中当前曲目的 MPMediaItem。

此 MPMediaItem 的插图属性为空，因此我想访问相册的插图。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

但是这个returns一个"Resource not Found"错误信息。

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，我发现这些返回的专辑 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 请求曲目信息并从那里获取专辑封面。
