    <p>When my class initializes, it adds itself as an observer for a bunch of different Wi-Fi notifications. For some reason, the selector isn't running when any of these things happen. Any ideas? Thank you ahead of time.</p> <pre><code>-(id) init { if (self) { sself = self; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleNotification:) name:CWModeDidChangeNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleNotification:) name:CWSSIDDidChangeNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleNotification:) name:CWBSSIDDidChangeNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleNotification:) name:CWCountryCodeDidChangeNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleNotification:) name:CWLinkDidChangeNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleNotification:) name:CWPowerDidChangeNotification object:nil]; </code></pre> <p>UPDATE: Here is the handleNotification method:</p> <pre><code>-(void) handleNotification:(NSNotification*) notification { NSLog(@"Notification Received"); } </code></pre> <p>I have included the CoreWLAN framework to my project: <img src="https://i.stack.imgur.com/5iNBg.png" alt="enter image description here"></p> <p>I've downloaded CoreWLANWirelessManager.app, and this is what I'm using for reference. Oddly enough, Apple's code is using deprecated notifications, and it still works. I've tried using the new API's and the deprecated API's with no success. I'm not sure if I can post their code here, but there is literally no difference. The selector even has the same name. </p> <p>Please don't hesitate to ask for further elaboration.</p> <p>UPDATE (After Dustin's answer): I've created a new project in hopes to isolate the issue. I set up my .h and .m files just as you described. Sadly, I'm still not getting any notifications. To show you I'm not lying (or crazy), I've included two (fairly crowded) screenshots that were taken during the same runtime. Notice: (1. I have a breakpoint in the handleNotification: method. The app never pauses. (2. I included the network window to show my Mac <em>has</em> indeed changed Wi-Fi networks during this runtime. (3. Nothing is NSLoged</p> <p>Network 1: <img src="https://i.stack.imgur.com/2HfgG.png" alt="enter image description here"></p> <p>Network 2: <img src="https://i.stack.imgur.com/veola.png" alt="enter image description here"></p> <p>UPDATE May 17, 2012: Dustin's answer was correct, but the Wi-Fi interface name varies depending on what hardware the app is running on. In my case, (MacBook Air; no ethernet), my Wi-Fi is en0 instead of en1. I managed to grab the system configuration plst file off my moms iMac, and the Wi-Fi is called en1. Ethernet is en0. Thank you all for your help.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
