Root.plist作为我的应用程序的一部分，我的文件中有以下设置Settings.bundle：

<dict>
    <key>PreferenceSpecifiers</key>
    <array>
        <dict>
            <key>Type</key>
            <string>PSMultiValueSpecifier</string>
            <key>Title</key>
            <string>Title</string>
            <key>Key</key>
            <string>my_key</string>
            <key>DefaultValue</key>
            <string>default_value</string>
            <key>Titles</key>
            <array>
                <string>Default Value</string>
                <string>First</string>
                <string>Second</string>
                <string>Third</string>
                <string>Fourth</string>
            </array>
            <key>Values</key>
            <array>
                <string>default_value</string>
                <string>one</string>
                <string>two</string>
                <string>three</string>
                <string>four</string>
            </array>
        </dict>
    </array>
    <key>StringsTable</key>
    <string>Root</string>
</dict>

我想访问TitlesandValues以便我可以有效地确定Title特定偏好的（即字符串表示），并将文本视图的文本分配给该值。

例如，

*defaultValue = [NSUserDefaults valueForKey:@"my_key"]; 
// let's say it's 'one'
textView setText:[[self getTitleForValue:defaultValue]]; 
// i want getTitleForValue to return 'First'

我必须自己解析Root.plist文件吗？然后手动构建/协调标题和值之间的映射？

设置列表足够长，我不希望在查找后不必编写 if 语句NSUserDefaults，所以我肯定想找到一个允许我查找它的解决方案。

对于标题：

NSLog(@"%@",[[[[yourdic objectForKey:@"PreferenceSpecifiers"] objectAtindex:0] objectForKey:@"Titles"] objectAtIndex:0]);

//或者

NSLog(@"%@",[[[yourdic objectForKey:@"PreferenceSpecifiers"] objectAtindex:0] objectForKey:@"Titles"]);

对于价值：

NSLog(@"%@",[[[[yourdic objectForKey:@"PreferenceSpecifiers"] objectAtindex:0] objectForKey:@"Values"] objectAtIndex:0]);

//或者

NSLog(@"%@",[[[yourdic objectForKey:@"PreferenceSpecifiers"] objectAtindex:0] objectForKey:@"Values"]);

对于那些感兴趣的人，这就是我最终得到的

NSString *bPath = [[NSBundle mainBundle] bundlePath];
NSString *settingsPath = [bPath stringByAppendingPathComponent:@"Settings.bundle"];
NSString *plistFile = [settingsPath stringByAppendingPathComponent:@"Root.plist"];
NSDictionary *settingsDictionary = [NSDictionary dictionaryWithContentsOfFile:plistFile];
NSArray *preferencesArray = [settingsDictionary objectForKey:@"PreferenceSpecifiers"];
NSArray *titles = [[preferencesArray objectAtIndex:0] objectForKey:@"Titles"];
NSArray *values = [[preferencesArray objectAtIndex:0] objectForKey:@"Values"];
int index = [values indexOfObject:currentValue];
if( index > -1 ){
    return [titles objectAtIndex:index];
}
return @"Default Title";
