iOS开发之Settings Bundle的简单使用

苹果官方文档

业界举例:

① 招行的后台运行时长选择列表

② 概念画板的Licenses展示

③ 搜狗输入法

④ outlook默认邮箱

Settings Bundle 实际上是Root.plist配置文件与NSUserDefault相关联的

使用之前需要先创建这样一个文件,target里找到settings bundle直接创建就行

然后需要在代码里添加注册代码

//MARK: - 注册setting bundle
- (void)registerDefaultsFromSettingsBundle{
    NSString *settingsBundle = [[NSBundle mainBundle] pathForResource:@"Settings" ofType:@"bundle"];
    if(!settingsBundle) {
        NSLog(@"Could not find Settings.bundle");
        return;
    }
    NSDictionary *settings = [NSDictionary dictionaryWithContentsOfFile:[settingsBundle stringByAppendingPathComponent:@"Root.plist"]];
    NSArray *preferences = [settings objectForKey:@"PreferenceSpecifiers"];
    NSMutableDictionary *defaultsToRegister = [[NSMutableDictionary alloc] initWithCapacity:[preferences count]];
    for(NSDictionary *prefSpecification in preferences) {
        NSString *key = [prefSpecification objectForKey:@"Key"];
         if(key) {
            [defaultsToRegister setObject:[prefSpecification objectForKey:@"DefaultValue"] forKey:key];
        }
    }
    [[NSUserDefaults standardUserDefaults] registerDefaults:defaultsToRegister];
}

在-application:didFinishLaunchingWithOptions:方法里调用即可实现配置的同步 (也可在进入前台时调用)

Group

Key	Value type	Value
`Type` (required)	String	类似, `PSGroupSpecifier` 这个值是固定写法
`Title` (localizable)	String	标题,类似tableview的组头
`FooterText` (localizable)	String	类似tableview的footer
`SupportedUserInterfaceIdioms`	Array	标识平台,支持多个平台差异化,可以创建多个类似文件,该字段作为标识

示例:

        <dict>
            <key>Type</key>
            <string>PSGroupSpecifier</string>
            <key>Title</key>
            <string>header标题文字</string>
            <key>FooterText</key>
            <string>footer文字</string>
        </dict>

Title和FooterText可以不填内容可用于分隔空间

<dict>
            <key>Type</key>
            <string>PSGroupSpecifier</string>
            <key>Title</key>
            <string></string>
</dict>

Multi Value Element

列表选择,只有单选模式,分为两个层级,外层显示默认选项或者已选选项,内层显示列表页

Key	Value type	Description
`Type` (required)	String	类似 `PSMultiValueSpecifier` 固定写法.
`Title` (required, localizable)	String	标题
`Key` (required)	String	关联userdefault偏好设置保存的值,这就是key
`DefaultValue` (required)	Any	默认值(必填)
`Values` (required)	Array	列表值数组,选取的标题对应的值
`Titles` (required, localizable)	Array	列表标题数组
`ShortTitles` (localizable)	Array	简短标题用于选中时同时显示标题和值(没有实际操作过)
`SupportedUserInterfaceIdioms`	Array	平台标识
`DisplaySortedByTitle`	Boolean	标题排序显示

示例:

<dict>
            <key>Type</key>
            <string>PSMultiValueSpecifier</string>
            <key>DisplaySortedByTitle</key>
            <true/>
            <key>Title</key>
            <string>环境切换</string>
            <key>Key</key>
            <string>default-env</string>

                <string>stg3</string>
                <string>stg4</string>
            </array>
        </dict>

Key	Value type	Value
`Type` (required)	String	类型`PSRadioGroupSpecifier`固定写法
`Title` (localizable)	String	标题.

            <string>cell-display</string>
        </dict>

Child Pane Element

子面板节点

`Title` (required, localizable)	String	标题
`File` (required)	String	创建的文件,放到bundle里,填写字段时无需后缀名

示例:
创建了一个child.plist的文件:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>StringsTable</key>
    <string>child</string>
    <key>PreferenceSpecifiers</key>
    <array>
        <dict>
            <key>Type</key>
            <string>PSGroupSpecifier</string>
            <key>Title</key>
            <string>这是子面板组头标题</string>
            <key>FooterText</key>
            <string>子面板菜单尾部说明文字</string>
        </dict>
        <dict>
            <key>Type</key>
            <string>PSMultiValueSpecifier</string>
            <key>DisplaySortedByTitle</key>
            <true/>
            <key>Title</key>
            <string>列表展示</string>
            <key>Key</key>
            <string>sssss</string>
            <key>DefaultValue</key>
            <string>stg1</string>
            <key>Values</key>
            <array>
                <string>prd</string>
                <string>stg1</string>
                <string>stg2</string>
                <string>stg3</string>
                <string>stg4</string>
            </array>
            <key>Titles</key>
            <array>
                <string>prd</string>
                <string>stg1</string>
                <string>stg2</string>
                <string>stg3</string>
                <string>stg4</string>
            </array>
        </dict>
        <dict>
            <key>Type</key>
            <string>PSChildPaneSpecifier</string>
            <key>Title</key>
            <string>详情信息展示</string>
            <key>File</key>
            <string>detail</string>
        </dict>
    </array>
</dict>
</plist>

child.plist又关联了一个detail.plist

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>StringsTable</key>
    <string>detail</string>
    <key>PreferenceSpecifiers</key>
    <array>
        <dict>
            <key>Type</key>
            <string>PSGroupSpecifier</string>
            <key>Title</key>
            <string></string>
            <key>FooterText</key>
            <string>The name of the schema file to load. (This file must be a property list file.) The string you specify for this key should not contain path information or the .plist filename extension of your schema file. The Settings app looks in the top-level of your settings bundle for a .plist file with the specified name. For example, if you had a MyPrefs.plist file, you would assign the value MyPrefs to this key. This key is required.</string>
        </dict>
    </array>
</dict>
</plist>

概念画板.app 就是这种实现,把开源的一些三方库的LICENSES全部展示在settings bundle里,就是用的子面板+group

Root.plist里关联只需如下即可:

<dict>
            <key>Type</key>
            <string>PSChildPaneSpecifier</string>
            <key>Title</key>
            <string>更多信息</string>
            <key>File</key>
            <string>child</string>
</dict>

把以上plist转成json来看就比较直观了(plist和JSON互转工具,关注公众号"飙码人生Coding" 回复关键字 20220321 领取)
