    <p>I have a problem within my app. I'm trying to find the user's location to the best preciseness in order to determine their zip-code. Currently I have a button that, when pressed, starts a method named <code>locateMe</code>. </p> <pre><code>-(IBAction)locateMe; { self.locationManager = [[CLLocationManager alloc] init]; locationManager.delegate = self; locationManager.desiredAccuracy = kCLLocationAccuracyBest; [locationManager startUpdatingLocation]; </code></pre> <p>Then I've implemented <code>didUpdateToLocation:</code></p> <pre><code>-(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation; { NSLog(@"Found location! %f,%f",newLocation.coordinate.latitude,newLocation.coordinate.longitude); } </code></pre> <p>I had previously done much more complicated stuff in <code>didUpdateToLocation</code> but as I tested some things I realized that the first location it found was not precise in the least. So, I put the <code>NSLog</code> call in there and it gave me an output similar to below...</p> <pre><code>Found location! 39.594093,-98.614834 Found location! 39.601372,-98.592171 Found location! 39.601372,-98.592171 Found location! 39.611444,-98.538196 Found location! 39.611444,-98.538196 </code></pre> <p>As you can see, it first gives me a value which is not correct, which was causing problems within my app because it wasn't giving the correct location.</p> <p>So, here's my question. Is there any way I can wait for the location manager to finish finding the most precise location?</p> <p>Thanks in advance!</p> <p><strong>EDIT:</strong> I'm wanting something like this:</p> <pre><code>if (newLocation.horizontalAccuracy &lt;= locationManager.desiredAccuracy) { } </code></pre> <p>But it never gets called!</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.
