How to create UITextField Programmatically

CGRect frame = CGRectMake(0, 0, 160, 29);
UITextField *search= [[UITextField alloc] initWithFrame:frame];
search.borderStyle = UITextBorderStyleRoundedRect;
search.textColor = [UIColor blackColor];
search.font = [UIFont systemFontOfSize:17.0];
search.placeholder = @"Suchen";
search.backgroundColor = [UIColor clearColor];
search.autocorrectionType = UITextAutocorrectionTypeNo;
search.keyboardType = UIKeyboardTypeDefault;
search.returnKeyType = UIReturnKeySearch;
search.clearButtonMode = UITextFieldViewModeWhileEditing;
search.delegate = self;

UIImageView *myView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"searchiCon.png"]];
[search  setRightView:myView];
[search  setRightViewMode:UITextFieldViewModeAlways];
[myView release];

// and add it to the toolbar as bar button item, if you wanted to use it as search field.

UIBarButtonItem *textFieldItem = [[UIBarButtonItem alloc] initWithCustomView:search];
