copied!<p>I am assuming an array, but it will work with dictionaries too.</p> <p>Userdefaults, Core Data and Plists can all be read/write but if you use a plist you need to pay attention in what dir you put it. See the plist part down below.</p> <p>Core Data I think it's way too much overkill, it's just strings. It's supposed to be used when you want to persist more complex objects.</p> <p><strong>NSUserDefaults</strong>:</p> <p>It's pretty fast and easy to do, though it's supposed to store only user settings. To write them to the userdefaults:</p> <pre><code>NSArray *stringsArray = [[NSArray alloc] arrayWithObjects: string1, string2, string3, nil]; [[NSUserDefaults standardUserDefaults] setObject:stringsArray forKey:@"MyStrings"]; [[NSUserDefaults standardUserDefaults] synchronize]; </code></pre> <p>To read the from the userdefaults:</p> <pre><code>NSArray *stringsArray = [[NSUserDefaults standardUserDefaults] objectForKey:@"MyStrings"]; </code></pre> <p><strong>Plist</strong>:</p> <p>If your strings are going to be modified you will need to write and read a plist but you cant't write into your app's resources.</p> <ol> <li><p>To have a read/write plist first find the documents directory</p> <pre><code>NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *stringsPlistPath = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"Strings.plist"]; </code></pre></li> <li><p>Create the array (I am assuming the strings are string1, ...)</p> <pre><code>NSArray *stringsArray = [[NSArray alloc] arrayWithObjects: string1, string2, string3, nil]; </code></pre></li> <li><p>Write it to file</p> <pre><code>[stringsArray writeToFile:stringsPlistPath atomically:YES]; </code></pre></li> </ol> <p>To read the plist:</p> <ol> <li><p>Find the documents directory</p> <pre><code>NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *stringsPlistPath = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"Strings.plist"]; </code></pre></li> <li><p>Read it in:</p> <pre><code>NSArray *stringsArray = [NSArray arrayWithContentsOfFile:stringsPlistPath]; </code></pre></li> </ol>
