所以我目前不得不手動將新電臺添加到我們的 CarPlay 應用程式中。但是，我們有一個 JSON，我們的應用程式將其用于 iPhone 和 iPad。所以我想知道如何創建一個使用這些資訊的串列，而不是我手動創建它。
func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene, didConnect interfaceController: CPInterfaceController) {
let DRN1 = CPListItem(text: "DRN1", detailText: "Perth's No.1 Online Station.")
let Hits = CPListItem(text: "DRN1 Hits", detailText: "Top 40 songs and yesturdays hits.")
let United = CPListItem(text: "DRN1 United", detailText: "Perth's Dedicated LGBTIQA Station.")
let Dance = CPListItem(text: "DRN1 Dance", detailText: "Playing the hottest dance tracks.")
if #available(iOS 14.0, *) {
let nowplay = CPNowPlayingTemplate.shared
DRN1.setImage(UIImage(imageLiteralResourceName:"DRN1Logo"))
DRN1.handler = { item, completion in
print("selected DRN1")
AdStichrApi.station = "DRN1"
MusicPlayer.shared.startBackgroundMusic(url:"https://api.example.com.au:9000/station/DRN1", type: "radio")
Nowplayinginfo().getsong()
DispatchQueue.main.asyncAfter(deadline: .now() 5.00) {
interfaceController.pushTemplate(nowplay, animated: true,completion:nil)
completion()
}
}
Hits.setImage(UIImage(imageLiteralResourceName:"DRN1Hits"))
Hits.handler = { item, completion in
print("selected Hits")
MusicPlayer.shared.player?.pause()
AdStichrApi.station = "DRN1Hits"
MusicPlayer.shared.startBackgroundMusic(url:"https://api.example.com.au:9000/station/DRN1Hits", type: "radio")
Nowplayinginfo().getsong()
DispatchQueue.main.asyncAfter(deadline: .now() 5.00) {
//interfaceController.presentTemplate(nowplay, animated: false)
interfaceController.pushTemplate(nowplay, animated: true,completion:nil)
completion()
}
}
United.setImage(UIImage(imageLiteralResourceName:"DRN1United"))
United.handler = { item, completion in
print("selected United")
AdStichrApi.station = "DRN1United"
MusicPlayer.shared.startBackgroundMusic(url:"https://api.example.com.au:9000/station/DRN1United", type: "radio")
// do work in the UI thread here
Nowplayinginfo().getsong()
DispatchQueue.main.asyncAfter(deadline: .now() 5.00) {
interfaceController.pushTemplate(nowplay, animated: true,completion:nil)
completion()
}
}
Dance.setImage(UIImage(imageLiteralResourceName:"DRN1Dance"))
Dance.handler = { item, completion in
print("selected Dance")
AdStichrApi.station = "dance"
MusicPlayer.shared.startBackgroundMusic(url:"https://api.example.com.au:9000/station/dance", type: "radio")
Nowplayinginfo().getsong()
DispatchQueue.main.asyncAfter(deadline: .now() 5.00) {
completion()
interfaceController.pushTemplate(nowplay, animated: true,completion:nil)
}
}
} else {
// Fallback on earlier versions
}
let listTemplate = CPListTemplate(title: "Select a Station", sections: [CPListSection(items:[DRN1,United,Hits,Dance])])
但是在我的 iOS 應用程式中，我只是使用
Api().getStations { (stations) in
self.stations = stations
}
它從后端獲取 JSON 并為我提供每個可用的站點。
我想知道如何使用此資訊創建 CPList。
示例：我找到了這個示例，但它正在獲取本地資料，此時我不需要標簽欄。
uj5u.com熱心網友回復：
試試這個：
// In some function in the CarPlaySceneDelegate
Api().getStations { (stations) in
var stationItems: [CPListItem] = []
self.radios = stations
for station in stations {
let item = CPListItem(text: station.name,
detailText: station.description
image: station.image)
item.handler = { [weak self] item, completion in
// manage what should happen on tap
// like navigate to NowPlayingView
}
stationItems.append(item)
}
loadList(withStations: stationItems)
}
// Load the list template
private func loadList(withStations stations: [CPListItem]) {
let section = CPListSection(items: stations)
let listTemplate = CPListTemplate(title: "Select a station",
sections: [section])
// Set the root template of the CarPlay interface
// to the list template with a completion handler
interfaceController?.setRootTemplate(listTemplate,
animated: true) { success, error in
// add anything you want after setting the root template
}
}
在陣列中添加站點的 for 回圈CPListItem 可以替換為map函式，但為了清楚起見，我這樣做了。
更新
在您的class CarPlaySceneDelegate, 修復拼寫 from
var interfactController: CPInterfaceController?
到
var interfaceController: CPInterfaceController?
在你的templateApplicationScene didConnect評論中interfactController?.setRootTemplate(listTemplate, animated: false)，現在
并將這一行添加到它self.interfaceController = interfaceController
所以更新后的函式如下所示：
func templateApplicationScene(_ templateApplicationScene: CPTemplateApplicationScene,
didConnect interfaceController: CPInterfaceController) {
// Add this
self.interfaceController = interfaceController
Api().getStations { (stations) in
var stationItems: [CPListItem] = []
self.stations = stations
for station in stations {
let item = CPListItem(text: station.name,
detailText: station.name
// image: imageLiteralResourceName:"DRN1Logo")
)
item.handler = { [weak self] item, completion in
// manage what should happen on tap
// like navigate to NowPlayingView
print(item)
}
stationItems.append(item)
}
self.loadList(withStations: stationItems)
}
}
你看到更好的結果了嗎？
