nested NSDictionary from plist

I have a plist, with main NSDictionary, in which its keys are dates. For every date, I have a NSDictionary in which the keys are (let's say) categories. Every Category holds Keys and values.

I would like to cre开发者_StackOverflow中文版ate 2 variables that each will hold the correct NSDictionary:

NSDictionary *dates = ?
NSDictionary *Categories = ?

Below is my plist, please help to understand how this should be done.

**Note: I do know how to assign the first dates dictionary from the plist... just stuck with the Categories.

NSDictionary *dict = [[NSDictionary alloc]initWithContentsOfFile:path];
self.dates = dict;
[dict release];

The plist:

<dict>
    <key>2010-05-08</key>
    <dict>
        <key>Catergory1</key>
        <dict>
            <key>key1</key>
            <string>value1</string>
            <key>key2</key>
            <string>value2</string>
            <key>key3</key>
            <string>value3</string>
        </dict>
        <key>Catergory2</key>
        <dict>
            <key>key1</key>
            <string>value1</string>
            <key>key2</key>
            <string>value2</string>
            <key>key3</key>
            <string>value3</string>
        </dict>
    <key>2010-01-02</key>
    <dict>
        <key>Catergory1</key>
        <dict>
            <key>key1</key>
            <string>value1</string>
            <key>key2</key>
            <string>value2</string>
            <key>key3</key>
            <string>value3</string>
        </dict>
        <key>Catergory2</key>
        <dict>
            <key>key1</key>
            <string>value1</string>
            <key>key2</key>
            <string>value2</string>
            <key>key3</key>
            <string>value3</string>
        </dict>
    </dict>
</dict>
</plist>

Any help would be greatly appreciated, as I've searched over the forum's history and found nothing that matches my scenario.

THANKS!

You should markup the values as arrays, so you can simply iterate over them.

<plist version="1.0">
<dict>
 <key>dates</key>
 <array>
  <dict>
   <key>date</key>
   <date>2010-05-17T12:40:32Z</date>
   <key>categories</key>
   <array>
    <dict>
     <key>key</key>
     <string>value</string>
    </dict>
    <dict>
     <key>key</key>
     <string>value</string>
    </dict>
   </array>
  </dict>
  <dict>
   <key>date</key>
   <date>2010-05-17T12:40:32Z</date>
   <key>categories</key>
   <array>
    <dict>
     <key>key</key>
     <string>value</string>
    </dict>
    <dict>
     <key>key</key>
     <string>value</string>
    </dict>
   </array>
  </dict>
 </array>
</dict>
</plist>

Code:

NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:pathToFile];
 for (NSDictionary *date in [dict valueForKey:@"dates"]) {
  NSArray *catgories = [date valueForKey:@"categories"];
 }
