 myTableView.frame = frame;

I created an iPad application in which I use searchBar , the searchBar data comes from the database, I store it in an array named tableData.

After this I pass this tabledata array to the tableView named myTableView, I am in the didLoad method The height of the table view is declared.

I want the height of the tableView to be dynamic according to the number of elements in the table,

This is a code snippet,

 // only show the status bar's cancel button while in edit mode

 sBar.autocorrectionType = UITextAutocorrectionTypeNo;

}


- (void)searchBarTextDidEndEditing:(UISearchBar *)searchBar 
{
 sBar.showsCancelButton = NO;
 [myTableView setHidden:TRUE];
}


- (void)searchBar:( UISearchBar *)searchBar textDidChang e:(NSString *)searchText

 [myTableView reloadData];

Declare myTableView in didLoad:

myTableView.frame=CGRectMake(550, 00, 220,400);

Look at the screenshot,
in the first In the image data, however, the tableView will not increase its size, and in the second image there is only 1 data, but the height is still being repaired.

As Atulkumar V. Jain said Try: in – (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText method to adjust the size of the table frame as follows:

CGRect frame = myTableView .frame;
frame.size.height = MIN(40 * [tableData count], 400); // 400 is the maximum height that the table view can have. You can change it to whatever you like
myTableView.frame = frame;

If this is useful to you, please let me know.
