Create NSArray from plist array

Question

I need to pull out data from a plist array and put it in an NSArray. But it seems to not be working.

Here is my main file:

NSString *path = [[NSBundle mainBundle] pathForResource:@"htmlData" ofType:@"plist"];
NSMutableDictionary *tempDictionary = [[NSMutableDictionary alloc] initWithContentsOfFile:path];

dictionary = tempDictionary;
[tempDictionary release];

NSMutableArray *nameArray = [[NSMutableArray alloc] init];
nameArray = [dictionary objectForKey:@"tagName"];

self.sitesArray = nameArray;

[nameArray release];

My plist file. Named: htmlData.plist

<plist version="1.0">
<dict>
    <key>tagName</key>
        <array>
            <string>&lt;html&gt;</string>
            <string>&lt;body&gt;</string>
        </array>
</dict>
</plist>

It should set self.sitesArray equal to @"<html>", @"<body>, nil; but it is not working.

Answer 1

First, understand that dictionary and tempDictionary are pointing to the same object, and you cannot access the object after you release it. So when you do [tempDictionary release] , the dictionary is released. It cannot be then accessed through the dictionary pointe.

For this code, try:

NSString *path = [[NSBundle mainBundle] pathForResource:@"htmlData" ofType:@"plist"];
NSDictionary *dictionary = [[NSMutableDictionary alloc] initWithContentsOfFile:path];  
self.sitesArray = [dictionary objectForKey:@"tagName"];
[dictionary release];

Your setter for sitesArray should be retaining the array, or the call to [dictionary release] will release it.
