    <p>I have a simple view controller (SecondViewController) used to manage a UITextview (I'm building a simple editor) this is the code of the SecondViewController.h <pre><code> @interface SecondViewController : UIViewController { IBOutlet UITextView *textView; } @property (nonatomic,retain) IBOutlet UITextView *textView; @end </pre></code> and this is the SecondViewController.m <pre><code></p> <p>// // EditorViewController.m // Editor // // Created by elio d'antoni on 13/01/11. // Copyright 2011 none. All rights reserved. // @implementation SecondViewController @synthesize textView;</p> <p>/* // Implement loadView to create a view hierarchy programmatically, without using a nib. - (void)loadView { } */</p> <p>// Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"uiViewBg.png"]]; textView.layer.borderWidth=1; textView.layer.cornerRadius=5; textView.layer.borderColor=[[UIColor darkGrayColor] CGColor]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillAppear:) name:UIKeyboardWillShowNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillDisappear:) name:UIKeyboardWillHideNotification object:nil];</p> <p>}</p> <p>-(void) matchAnimationTo:(NSDictionary *) userInfo { NSLog(@"match animation method"); [UIView setAnimationDuration:[[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] doubleValue]]; [UIView setAnimationCurve:[[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] intValue]]; }</p> <p>-(CGFloat) keyboardEndingFrameHeight:(NSDictionary *) userInfo { NSLog(@"keyboardEndingFrameHeight method");</p> <pre><code>CGRect keyboardEndingUncorrectedFrame = </code></pre> <p>[[ userInfo objectForKey:UIKeyboardFrameEndUserInfoKey ] CGRectValue]; CGRect keyboardEndingFrame = [self.view convertRect:keyboardEndingUncorrectedFrame fromView:nil]; return keyboardEndingFrame.size.height; }</p> <p>-(CGRect) adjustFrameHeightBy:(CGFloat) change multipliedBy:(NSInteger) direction { NSLog(@"adjust method");</p> <pre><code>return CGRectMake(20, 57, self.textView.frame.size.width, self.textView.frame.size.height + change * direction); </code></pre> <p>} -(void)keyboardWillAppear:(NSNotification *)notification { NSLog(@"keyboard appear"); [UIView beginAnimations:nil context:NULL]; [self matchAnimationTo:[notification userInfo]]; self.textView.frame = [self adjustFrameHeightBy:[self keyboardEndingFrameHeight: [notification userInfo]] multipliedBy:-1]; [UIView commitAnimations]; } -(void)keyboardWillDisappear:(NSNotification *) notification { NSLog(@"keyboard disappear"); [UIView beginAnimations:nil context:NULL]; [self matchAnimationTo:[notification userInfo]]; self.textView.frame = [self adjustFrameHeightBy:[self keyboardEndingFrameHeight: [notification userInfo]] multipliedBy:1]; [UIView commitAnimations]; }</p> <p>// Override to allow orientations other than the default portrait orientation. - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; }</p> <ul> <li><p>(void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning];</p> <p>// Release any cached data, images, etc that aren't in use. }</p></li> <li><p>(void)viewDidUnload { // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; }</p></li> <li><p>(void)dealloc { [super dealloc]; }</p></li> </ul> <p>@end </pre></code> the problem is that if load the view controller from a tab bar controller the textView doesn't resize when the keyboard appear, but the SAME code works if loaded as a single view based app. I hope I was clear enough. I used the tabBar template provided by xcode no modifications.</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.
