This is something that I have worked out. <a href="http://dl.dropbox.com/u/35012982/Demo%20Projects/TestViewMatrix.zip" rel="nofollow">Source Code</a> An enumerated type to denote you want vertial or horizontally arranged items <pre><code>typedef enum { ArrangementTypeHorz = 1, ArrangementTypeVert = 2 }ArrangementType; </code></pre> Declared number or rows columns and arrangement type <pre><code>@interface ATTViewController () { ArrangementType _arrangementType; NSUInteger _rows; NSUInteger _columns; } @end </code></pre> Method calculates the frame of an item index wrt superView <pre><code>- (CGRect)frameForItemAtIndex:(NSUInteger)index inSuperView:(UIView *)superView { CGFloat blockWidth = floorf(superView.frame.size.width/_columns); CGFloat blockHeight = floorf(superView.frame.size.height/_rows); NSUInteger row = 0; NSUInteger column = 0; if (_arrangementType == ArrangementTypeHorz) { row = floorf((CGFloat)index/_columns); column = index - row*_columns; }else{ column = floorf((CGFloat)index/_rows); row = index - column*_rows; } CGFloat xOffset = 5.0f; CGFloat yOffset = 5.0f; return CGRectMake(blockWidth*column+xOffset, blockHeight*row+yOffset, blockWidth-(2*xOffset), blockHeight-(2*yOffset)); } </code></pre> Adding Buttons to a containerView. While adding set the rows, columns and arrangementType <pre><code>- (void)addButtonsToContainerView { NSUInteger numberOfItems = 5; _rows = 2; _columns = 3; _arrangementType = ArrangementTypeVert; NSUInteger itemCount = 0; while (itemCount<numberOfItems) { UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; CGRect frame = [self frameForItemAtIndex:itemCount inSuperView:self.containerView]; [button setFrame:frame]; NSString *title = [NSString stringWithFormat:@"Button %d",itemCount+1]; [button setTitle:title forState:UIControlStateNormal]; [self.containerView addSubview:button]; itemCount ++; } } </code></pre>

Guidance

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.
