    <p>I am trying to attach multiple photos in a <code>MailComposerViewController</code> and I am using <code>ALAssetPickerViewController</code> to pick multiple photos. I have an <code>NSMutableArray</code>, which contains reference of selected assets. I am implementing a <code>for loop</code> which is enumerating over <code>array</code> of selected assets to get <code>NSData</code> of <code>UIImage</code> and <code>UIImage</code> is initialized with <code>CGImageRef</code>. Code is as written below:</p> <pre><code>@autoreleasepool { NSString *emailTitle = @"Test"; NSString *messageBody = @"IOS programming is so fun!"; NSArray *toRecipents = [NSArray arrayWithObjects:@"abc@gmail.com", nil]; MFMailComposeViewController *tempmcvc = nil; tempmcvc = [[MFMailComposeViewController alloc] init]; tempmcvc.mailComposeDelegate = self; [tempmcvc setSubject:emailTitle]; [tempmcvc setMessageBody:messageBody isHTML:YES]; [tempmcvc setToRecipients:toRecipents]; tempmcvc.modalPresentationStyle=UIModalPresentationFullScreen; tempmcvc.navigationBar.barStyle = UIBarStyleBlackOpaque; for (AlAsset *assets in SelectedAssetsarray) { @autoreleasepool { UIImage *attachImagTemp = nil; NSData *myData = nil; CGImageRef iref = [assets.defaultRepresentation fullScreenImage]; NSString *nameOfImgTemp; attachImagTemp = [UIImage imageWithCGImage:iref]; nameOfImgTemp = assets2.defaultRepresentation.filename; myData = UIImageJPEGRepresentation (attachImagTemp, 1.0); [tempmcvc addAttachmentData:myData mimeType:@"image/jpeg" fileName:nameOfImgTemp]; myData = nil; attachImagTemp = nil; iref = nil; nameOfImgTemp = nil; ALAsset *_temp = assets2; _temp = nil; } } } dispatch_async(dispatch_get_main_queue(), ^(void) { [self presentModalViewController:tempmcvc animated:YES] }); </code></pre> <p>Each asset I am attaching hardly is of 2 MB, but memory is constantly decreasing I am unable to release the memory properly; some memory is leaking please help to find the leak. </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.
