uiwebview Rotation Problem

Best solution: Set constraints on the UIWebView. When the View rotated, the space constraints should automatically adjust.

UITableView with Multiple Sections

 - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
      return 2 ;
 }

 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
      if (section==0)
      {
             return [array1 count];
      }
      else{
             return [array2 count];
      }
 }

 - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {

 if(section == 0)
      return @"Section 1";
 if(section == 1)
      return @"Section 2";
 }

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{

      static NSString *CellIdentifier = @"Cell";

      UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
     if (cell == nil) {
      cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
      }

 if (indexPath.section==0) {
     ObjectData *theCellData = [array1 objectAtIndex:indexPath.row];

Expanding and Collapsing table view cells in ios

Find a great code for expanding and collapsing table view on apple developer webiste. This is the link:

"TableViewUpdates" demonstrates how you can use animated updates to open and close sections of a table view for viewing, where each section represents a play, and each row contains a quotation from the play. It also uses gesture recognizers to respond to user input: * A UITapGestureRecognizer to allow tapping on the section headers to expand the section; * A UIPinchGestureRecognizer to allow dynamic changes to the height of table view rows; and * A UILongPressGestureRecognizer to allow press-and-hold on table view cells to initiate an email of the quotation.
