    <p>I wanted to create a main view which consists of a add button. </p> <p>On each click on the add button a subview must be added in the main view.the subview is present in another class which consists of a close button,on click of the close button the subview class informs the main view through delegate function and the particular subview mist get removed from the main view. </p> <p>The remaining subviews must be repositioned in the main view.</p> <p>I want the subviews to be added in the main view in <strong>matrix form(2xN)</strong> matrix. That is 2 subviews in one rows and n number of columns. </p> <p>I have implemented two methods for the same, but the subviews are not getting repositioned.</p> <p><strong>method 1 :</strong></p> <pre><code> - (IBAction)btnAddView:(id)sender { if ((count%2)==0) { NewSubView *subView = [[NewSubView alloc]initWithFrame:CGRectMake(10, 10+ (i*120), 100, 100) andDelegate:self]; // [self.view addSubview:subView]; [arr addObject:subView]; i++; } else if ((count%2)==1) { NewSubView *subView = [[NewSubView alloc]initWithFrame:CGRectMake(120, 10+(j*120), 100, 100) andDelegate:self]; // [self.view addSubview:subView]; [arr addObject:subView]; j++; } count = count+1; for (int x=0; x&lt;[arr count]; x++) { [self.view addSubview:[arr objectAtIndex:x]]; } self.lblCount.text = [ NSString stringWithFormat:@"count: %d",count]; } // the delegate function for deleting the view is as follows - (void) handleDelegate:(id)sender { int deletedIndex; for (int val=0; val&lt;[arr count]; val++) { if([[arr objectAtIndex:val] isEqual:sender]) deletedIndex =val; } dupArray =[[NSMutableArray alloc]initWithArray:arr]; [arr removeObjectAtIndex:deletedIndex]; [sender removeFromSuperview]; count--; self.lblCount.text = [ NSString stringWithFormat:@"count: %d",count]; if ((deletedIndex%2)==0) i=deletedIndex/2; if ((deletedIndex%2)==1) j--; } </code></pre> <p><strong>method 2:</strong> </p> <pre><code> - (IBAction)btnAddView:(id)sender { int modifiedColValue= 10+(colValue*120); if (modifiedColValue&lt;320) { NewSubView *subView = [[NewSubView alloc]initWithFrame:CGRectMake(rowValue, modifiedColValue, 100, 100) andDelegate:self]; [arr addObject:subView]; colValue++; } else if (modifiedColValue&gt;320) { rowValue=10; [self btnAddView:sender]; colValue++; } count++; for (int x=0; x&lt;[arr count]; x++) { [self.view addSubview:[arr objectAtIndex:x]]; } } </code></pre> <p>how can i reposition the remaining subviews,where count is the number of subviews, 320 is the width of the main view.</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.
