read multi-array from plist - objective-c

Question

I can't get it work to have the 8 items from the plist below.
I have a plist "settings.plist". Now I wan't from vragen -> category (self.catagorie - 1) -> question. The 8 items. But the array keeps empty.
What am I doing wrong?
Code:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:#"instellingen.plist"];
NSMutableDictionary *instellingen = [NSMutableDictionary dictionaryWithContentsOfFile:path];
NSArray *vragen = [instellingen objectForKey:#"vragen"];
NSArray *cata = [vragen objectAtIndex: (self.catagorie-1)];
NSArray *question = [cata objectAtIndex: 0];
NSLog(#"count: %i", [question count]);
Plist file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

<key>vragen</key>

<array> <--catagorydata
<array> <-- questiondata
<string>vraag</string>
<string>A</string>
<string>B</string>
<string>C</string>
<string>D</string>
<string>1</string>
<string>standaard</string>
<string></string>
</array>
<array>
<string>vraag2</string>
<string>A</string>
<string>B</string>
<string>C</string>
<string>D</string>
<string>1</string>
<string>afbeelding</string>
<string>afbeelding.jpg</string>
</array>
</array>
</array>
<key>firstBoot</key>
<true/>
<key>regelAtRuntime</key>
<true/>
</dict>
</plist>

Answer 1

First of all this line
NSString *path = [documentsDirectory stringByAppendingPathComponent:#"instellingen.plist"]; ?
should be
NSString *path = [documentsDirectory stringByAppendingPathComponent:#"settings.plist"];
I also had to delete these from the dictionary:
<--catagorydata
<-- questiondata
Besides the two things above, there is nothing wrong with your code or your dictionary.
After making those changes I tested your code and the output I got was:
tester[69637:c07] size of dict 3
tester[69637:c07] count: 8
which is correct according to the .plist file
So your problem is at the first 4 lines. Make sure your file is in Documents directory (use something like the following code to see whats going wrong)
NSLog(#"Path : %#",path);
I copied the file in the project folder (because I used the simulator) and used the following code and everything worked fine
NSBundle* b=[NSBundle mainBundle];
NSURL* path1=[b URLForResource:#"settings" withExtension:#"plist"];
NSMutableDictionary *instellingen = [NSMutableDictionary dictionaryWithContentsOfURL:path1];
NSLog(#"size of dict %d",[instellingen count]);
NSArray *vragen = [instellingen objectForKey:#"vragen"];
NSArray *cata = [vragen objectAtIndex: 0];
NSArray *question = [cata objectAtIndex: 0];
NSLog(#"count: %i", [question count]);

Just a quick read, but looks like you have an array of "categoryData" items, that contains an array of questionData items; questionData items are strings.
NSArray *vragen = [instellingen objectForKey:#"vragen"]; // count = 1
NSArray *cata = [vragen objectAtIndex: (self.catagorie-1)]; // count = 2
NSString *question = [cata objectAtIndex: 0];
Recommend you add some breakpoints and look at your data. OR, NSLog(#"data = %#", cata); etc.
