    <p>After I select a photo with the camera I'm saving it as <code>NSData</code>. This takes a while and I dont want my users to wait for it. I want it to happen at the background. My question is whether it is wise to perform methods after I call "<code>dismissModalViewControllerAnimated:NO</code>".</p> <p>this is my code, which outputs the following:</p> <p>debug1<br> debug2<br> debug4<br> debug5<br> debug6<br> debug3</p> <pre><code>- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { // Access the uncropped image from info dictionary UIImage *image = [info objectForKey:@"UIImagePickerControllerOriginalImage"]; NSLog(@"debug1"); // Save image in the normal photo album UIImageWriteToSavedPhotosAlbum(image, self, @selector(image:didFinishSavingWithError:contextInfo:), nil); NSLog(@"debug2"); [[MySingleton sharedSingleton] addImg:image]; NSLog(@"debug3"); [picker dismissModalViewControllerAnimated:NO]; [_delegate startStep2]; } -(void) addImg: (UIImage *) img { NSLog(@"debug4"); NSData *jpegData = UIImageJPEGRepresentation([img rotateAndScaleFromCameraWithMaxSize:1500.0], 0.9f); NSLog(@"debug5"); image = [[NSData alloc] initWithData:jpegData]; NSLog(@"debug6"); } </code></pre> <p>Can I dismiss the viewcontroller first and than do other stuff, or isnt that a good way?</p> <p>edit// I did solve the waiting problem by doing this:</p> <pre><code>[[MySingleton sharedSingleton] performSelectorInBackground:@selector(addImg:) withObject:image]; </code></pre>

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.
