一. 实现
1. 创建变量
@State var search: String = ""
2. 过滤
此处过滤条件为判断元素是否包含搜索的文本。
<Your-Array>.filter({"\($0)".contains(search.lowercased()) || search.isEmpty})
二. 汇总
struct DataList: View {
@State var search: String = ""
@Binding var dataList: [Item]
var dataSearchFilterList: [Item] {
dataList.filter({"\($0)".contains(search.lowercased()) || search.isEmpty})
}
var body: some View {
if dataSearchFilterList.isEmpty {
Text("搜索不到...")
} else {
... // 展示搜索结果
}
}
}
