Hi,
I am trying to read some values from a plist. I know how to read in the
whole list (see eg Hillegass' book page 335). What I cannot figure out from
the NSDictionary information is how to get the value that belongs to a
certain key in a 'multilevel' plist. Here's a snippet of my test.plist:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist SYSTEM "file://localhost/System/Library/DTDs/PropertyList.dtd">
<plist version="0.9">
<dict>
<key>testkeys</key>
<dict>
<key>KeyA</key>
<dict>
<key>KeyA1</key>
<string>6</string>
<key>KeyA2</key>
<string>20</string>
<key>KeyA3</key>
<string>Heptose</string>
<key>KeyA4</key>
<string>6</string>
<key>KeyA5</key>
<string>40</string>
</dict>
<key>KeyB</key>
<dict>
<key>KeyB1</key>
<string>6</string>
<key>KeyB2</key>
<string>0</string>
<key>KeyB3</key>
<string>Heptose</string>
<key>KeyB4</key>
<string>6</string>
<key>KeyB5</key>
<string>0</string>
</dict>
...
...
</dict>
</dict>
If I use the code example from Hillegass' book:
path = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"plist"];
myList = [NSDictionary dictionaryWithContentsOfFile: path];
myArray = [myList objectForKey:@"testkeys"];
NSLog(@"test = %@", myArray);
Then I get all keys and values. If I use myArray = [myList
objectForKey:@"KeyA2"] then myList is null.
So, how do I store in an array all the values from a similar key, for
instance KeyA3, KeyB3, etc? And is it possible to get an array with KeyA,
KeyB, ... (thus not the values)?
many thanks,
- Koen.
