问题描述
“我的窗口小部件”从UserDefaults/ Appgroups加载一些数据，并根据它显示一些文本和图片。
这是从头开始的。
如果我更改UserDefaults并使用WidgetCenter.shared.reloadAllTimelines()，则仅更改图片而不更改文本。
我该怎么办？还有其他选项可以在主应用程序和小部件之间共享数据吗？似乎是一个错误。
这是我的Widgetentry：
struct Provider: IntentTimelineProvider {
let networkManager = NetworkManager()
func placeholder(in context: Context) -> SimpleEntry {
SimpleEntry(date: Date(),configuration: ConfigurationIntent(),clubnamehome: "test",clubnameaway: "test2")
}
func getSnapshot(for configuration: ConfigurationIntent,in context: Context,completion: @escaping (SimpleEntry) -> ()) {
networkManager.fetchData { (post) in
let entry = SimpleEntry(date: Date(),configuration: configuration,clubnamehome: post.home_name,clubnameaway: post.away_name)
completion(entry)
}
}
func getTimeline(for configuration: ConfigurationIntent,completion: @escaping (Timeline<Entry>) -> ()) {
networkManager.fetchData { (post) in
let entries = [ SimpleEntry(date: Date(),clubnameaway: post.away_name) ]
let reloadTime = Calendar.current.date(byAdding: .minute,value: 5,to: Date())!
let timeline = Timeline(entries: entries,policy: .after(reloadTime))
completion(timeline)
}
}
}
在这里我设置UserDefault的值：
@IBAction func losGehts(_ sender: UIButton) {
switch team {
case "arminia":
UserDefaults(suiteName: "...")!.set("114",forKey: "tabellenId")
if #available(iOS 14.0,*) {
WidgetCenter.shared.reloadAllTimelines()
} else {
// Fallback on earlier versions
}
case "augsburg":
这是我的看法：
struct MyTeamWidgetEntryView : View {
@Environment(\.colorScheme) var colorScheme
var imageIcon = "stuttgart"
var entry: Provider.Entry
let logo = UserDefaults(suiteName: "...")!.string(forKey: "logo")
let mannschaftsName = UserDefaults(suiteName: "...")!.string(forKey: "teamname")
let teamID = "289"
var body: some View {
HStack {
Spacer()
vstack (alignment: .leading,spacing: 0) {
Spacer().frame(height: 10)
// image von hier
HStack {
Spacer()
switch logo {
case "arminia":
Image("bundesliga1/arminia").resizable().aspectRatio(contentMode: .fit).frame(width: 25,height: 25,alignment: .bottomLeading)
case "augsburg":
Image("bundesliga1/augsburg").resizable().aspectRatio(contentMode: .fit).frame(width: 25,alignment: .bottomLeading)
default:
Image("bundesliga1/...").resizable().aspectRatio(contentMode: .fit).frame(width: 90,height: 90,alignment: .center)
}
Spacer()
}
// image bis hier
Spacer().frame(height: 5)
}
Spacer()
vstack (alignment: .leading,spacing: 6) {
vstack {
HStack{
Text(entry.clubnamehome).font(.system(size: 10)).bold()
Text(":").font(.system(size: 10)).bold()
Text(entry.clubnameaway).font(.system(size: 10)).bold()
Spacer()
//überlegen ob spacer rein soll oder nicht
}
}
}
}
}
解决方法
您似乎从应用组UserDefaults中正确读取了logo和mannschaftsName值：
struct MyTeamWidgetEntryView : View {
let logo = UserDefaults(suiteName: "...")!.string(forKey: "logo")
let mannschaftsName = UserDefaults(suiteName: "...")!.string(forKey: "teamname")
现在，您需要确保在主应用程序中正确设置了这些值。在您发布的代码中，您只能为tabellenId键设置一个值：
case "arminia":
UserDefaults(suiteName: "...")!.set("114",forKey: "tabellenId")
您还需要更新logo和mannschaftsName：
case "arminia":
UserDefaults(suiteName: "...")!.set("114",forKey: "tabellenId")
UserDefaults(suiteName: "...")!.set("???",forKey: "logo")
UserDefaults(suiteName: "...")!.set("???",forKey: "mannschaftsName")
这可能是摘录的，所以您不要重复自己：
switch team {
...
}
UserDefaults(suiteName: "...")!.set(team,forKey: "mannschaftsName")
