获取随机NSDictionary的关键？

Question

你好的StackOverflow社区，

<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

现在我想从获得 “嘿嘿” 字符串 “hello”。

非随机密钥的解决方案！ 但我有随机密钥，也该issn't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" 

但它如何与这个“随机密钥”的作品？

先谢谢您。

也许，你可以解释我，我如何设置一个随机密钥？ 也是顶部的例子，而不是“得到”我会“设置”:)

你可以迭代“非随机密钥”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); 
}
