Both key and values in the Dictionary are strings.
Note that a table view is designed to display a flat list (array) of
items, while a dictionary is a tree structure. Your data would
probably fit better in a table view if it looked like this:
<plist version"1.0">
<key>People</key>
<array>
<dict>
<key>name</key><string>John</string>
<key>age</key><string>29</string>
<key>height</key><string>5 Foot 10 inches</string>
</dict>
<dict>
<key>name</key><string>Mary</string>
<key>age</key><string>27</string>
<key>height</key><string>5 Foot 3 inches</string>
</dict>
</array>
</plist>
I want auto populate the table view with the NSDictionary from People.
What do I need to do to this?
You're not populating the table view, you're populating the array
controller. The array controller will in turn feed the table view
automatically via the bindings. If the table view and the array
controller is set up already, you should be able to just use
"setContentArray:" or similar to populate the array controller with
the data from the file.
Also note that this code is conceptually wrong, bindings or no bindings:
NSEnumeration* enumerator = [people objectEnumerator];
NSDictionary* person = nil;
while ( ( person = (NSDictionary*) [enumerator nextObject] ) )
[tableView ?: person];
You never set data in a table view. The table view is just a view of
the things found in the "table view data source". The table view
fetches data for display from it's data source, traditionally via the
NSTableDataSource protocol, now perhaps more often via an
NSArrayController.
