Enable Keyboard return button for Textfield:

this button call following fuction default:

- (BOOL)textFieldShouldReturn:(UITextField *)textField 

{

  [textField resignFirstResponder]; 

   return YES; 

}

Enable Keyboard return button for SearchBar:

this button call following fuction default:

- (void)searchBarTextDidEndEditing:(UISearchBar *)searchBar

{

searchBar.showsCancelButton = NO;

}

Deselect the UITableCell:

By Default, when we select the table cell it Become Blue so we can avoid it by

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)  newIndexPath 

{ 

    [tableView deselectRowAtIndexPath:[tableView indexPathForSelectedRow] animated:YES]; 

}

open safari from Application:

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"Enter URL Here"]];

Convert NSData to NSString:

NSString *str = [[NSString alloc] initWithData:aData encoding:NSASCIIStringEncoding];

Convert NSString to NSData:

NSData *data = [aStr dataUsingEncoding: NSASCIIStringEncoding];

Change UIAlertView Button Color:

Create the object of UIAlertView , the call automatically following method:

- (void)willPresentAlertView:(UIAlertView *)alertView 

{ 

[[[alertView subviews] objectAtIndex:1] setBackgroundColor:[UIColor redColor]];

    /*

      Here index 0 = Title , 1 = cancel Button , 2,3.... = otherButton

*/

} 

To scroll the view at time of Editing textfield and keyboard appear: 

just set the frame of view in textFieldDidBeginEditing such as:

     self.view.frame=CGRectMake(0,-30, 320, 460);

and again set the view in textFieldDidEndEditing as:

    self.view.frame=CGRectMake(0,0, 320, 460);

Get the Index path of table Row by table field such as in  textFieldDidBeginEditing method:

    When we use text field in UITableView.

- (void) textFieldDidBeginEditing:(UITextField *)textField 

{

UITableViewCell *cell = (UITableViewCell*) [[textField superview] superview];

NSIndexPath *path = [mytable indexPathForCell:cell]; 

    // use this path as indexpath of table fuction

}
