iphone - 获取随机 NSDictionary 键？

Question

StackOverflow 社区您好，

<plist>
<dict>
    <key>Non Random Key</key>
    <dict>
        <key>Random Key</key>
        <dict>
            <key>Hello</key>
            <string>Hey</string>
            <key>Banana</key>
            <string>Bread</string>
        </dict>
    </dict>
</dict>
</plist>

这是我的 Plist 文件.../this/is/the/path.plist

现在我想从“Hello”中获取“Hey”字符串。

非随 secret 钥的解决方案!但我有一个随 secret 钥，这也不是解决方案......

NSMutableDictionary* plistDict = [[NSMutableDictionary alloc] initWithContentsOfFile:@"/this/is/the/path.plist"];

NSString *value;
value = [plistDict objectForKey:@"/Non Random Key/Random Key/Hello"];
// value is "Hey"

但是它如何与“随 secret 钥”一起使用？

提前谢谢您。

也许，你可以解释一下，我如何设置随 secret 钥？还有顶部的示例，但我会“设置”而不是“获取”:)

您可以迭代“非随机键”字典。这应该有帮助:NSDictionary iterate

NSMutableDictionary* plistDict = [[NSMutableDictionary alloc] initWithContentsOfFile:@"/this/is/the/path.plist"];

NSDictionary *nonRandomDic = [plistDic valueForKey:@"NonRandomKey"];


NSEnumerator *enumerator = [nonRandomDic keyEnumerator];
id key;
while ((key = [enumerator nextObject])) {
  NSString *tmp = [nonRandomDic objectForKey:key];
  NSLog(@"Your String %@ from the Random Key %@", tmp, key);
}
