我想通过我的应用程序更改 PSMultiValueSpecifier 标题数组和值数组。这是我的 Root.plist 文件。

</array>
<key>StringsTable</key>
<string></string>

I tried to change like this Through my application.
<dict>
<key>Type</key>
<string>PSMultiValueSpecifier</string>
<key>Title</key>
<string>Default Language</string>
<key>Key</key>
<string>Default_Language_key</string>
<key>DefaultValue</key>
<integer>0</integer>
<key>Titles</key>
<array>
<string>English</string>
</array>
<key>Values</key>
<array>
<integer>0</integer>
</array>
</dict>

但这不会改变标题和值。请有人帮助我。下面给出了我使用的代码。

NSURL * settingsURL =  [[NSBundle bundleWithURL:[[NSBundle mainBundle] URLForResource:@"Settings" withExtension:@"bundle"]]
                        URLForResource:@"Root" withExtension:@"plist"];
NSMutableDictionary * settingsDict = [NSMutableDictionary    dictionaryWithContentsOfURL:settingsURL];
NSMutableArray *settingsArr = [settingsDict objectForKey:@"PreferenceSpecifiers"];

NSMutableDictionary *loTempDict = [[NSMutableDictionary alloc] init];
loTempDict = [settingsArr objectAtIndex:5];

NSArray *title_Array = [loTempDict objectForKey:@"Titles"];
NSArray *value_Array = [loTempDict objectForKey:@"Values"];

NSArray *lanArray_title = [NSArray arrayWithObject:@"French"];
NSArray *lanArray_value = [NSArray arrayWithObject:@"0"];

[loTempDict setObject:lanArray_title forKey:@"Titles"];
[loTempDict setObject:lanArray_value forKey:@"Values"];
[settingsArr replaceObjectAtIndex:5 withObject:loTempDict];


NSLog(@"final settingsArr ===%@ ",settingsArr);

NSString *settingsBundle = [[NSBundle mainBundle] pathForResource:@"Settings" ofType:@"bundle"];

[settingsArr writeToFile:[settingsBundle stringByAppendingPathComponent:@"Root.plist"] atomically: TRUE];

谢谢

你得到答案了吗？

标签： objective-c settings.bundle root.plist

【解决方案1】：

这会解决你的问题

NSString *settingsBundle = [[NSBundle mainBundle] pathForResource:@"Settings" ofType:@"bundle"];

[settingsDict setValue:settingsArr forKey:@"PreferenceSpecifiers"];

[settingsDict writeToFile:[settingsBundle stringByAppendingPathComponent:@"Root.plist"] atomically: TRUE];

【讨论】：

没有。这无济于事，因为您无法写入应用程序的主包。 -1.

【解决方案2】：

你不能这样做。出于安全原因，无法写入应用程序包。您能想到的最佳选择是将要修改的文件从 app bundle 目录复制到 Library 或 Documents 目录 - 这些是可写的，并且可以更新其中的文件。
