SwiftUI SearchField

The search input box component can be placed in a non-specific location and is consistent with the default search input box style.

✦ My macOS/iOS application ✦

Installation

You can add MarkdownUI to an Xcode project by adding it as a package dependency.

1. From the File menu, select Add Packages…
2. Enter https://github.com/jaywcjlove/swiftui-searchfield the Search or Enter Package URL search field
3. Link SearchField to your application target

Or add the following to Package.swift:

.package(url: "https://github.com/jaywcjlove/swiftui-searchfield", from: "1.0.1")

Or add the package in Xcode.

Usage

public init(searchText: Binding<String>,
            placeholder: String? = nil,
            onEditingChanged: ((Bool) -> Void)? = nil,
            onTextChanged: ((String) -> Void)? = nil,
            searchField: ((NSSearchField) -> Void)? = nil)

Parameters

• searchText: A binding to the string for the search text.
• placeholder: An optional placeholder string that is displayed when the input field is empty.
• onEditingChanged: A closure that is called when the editing state changes, returning a boolean value that indicates whether editing has started or ended.
• onTextChanged: A closure that is called when the text changes, returning the current search text.
• searchField: A closure that allows access to the NSSearchField instance for custom operations.

import SwiftUI

struct ContentView: View {
    @State private var searchText = ""
    var body: some View { 
        SearchField(
            searchText: $searchText,
            placeholder: "Search...",
            searchField: { searchField in
                print(type(of: searchField)) // -> NSSearchField
            }
        )
    }
}

In this example, SearchField is initialized and bound to the @State variable searchText, and the text entered by the user will be printed to the console.

Example: Handling Editing State

import SwiftUI
import SearchField

struct ContentView: View {
    @State private var searchText = ""
    @State private var isEditing = false

    var body: some View {
        SearchField(
            searchText: $searchText,
            placeholder: "Search...",
            onEditingChanged: { editing in
                isEditing = editing
                print("Editing started: \(editing)")
            },
            onTextChanged: { text in
                print("Search text changed to: \(text)")
            }
        ) { searchField in
            print(type(of: searchField)) // -> NSSearchField
        }
    }
}

In this example, the onEditingChanged closure is used to handle changes in the editing state.

Example: Accessing the NSSearchField Instance

import SwiftUI
import SearchField

struct ContentView: View {
    @State private var searchText = ""
    @State private var searchField: NSSearchField?

    var body: some View {
        SearchField(
            searchText: $searchText,
            placeholder: "Search...",
            searchField: { field in
                // 自定义 NSSearchField 的属性
                field.isBordered = true
                field.isBezeled = true
            }
        )
    }
}

import SearchField

struct ContentView: View {
    @State private var searchText = ""
    var body: some View {
-        SearchField(searchText, textFieldChanged: { value in
+        SearchField(searchText: $searchText, placeholder: "Search...") { text in
-            print("value\(value)")
-            searchText = value
+            print("Search text changed to: \(text)")
+        })
-        }
        Text(searchText)
    }
}

import SwiftUI
import SearchField

struct ContentView: View {
    @State private var searchText = ""

    var body: some View {
        SearchField(
            searchText: $searchText,
            placeholder: "Search...",
            searchField: { searchField in
                print(type(of: searchField)) // -> NSSearchField
            }
        )
    }
}
