Unable to set rightview or leftview in textfield of searchbar in ios 7

Question

Purpose: I want to set right view as label in searchbar's textfield

Following Code working fine in ios 6 for doing the same thing:

UISearchBar  *search = [[UISearchBar alloc] init];
[search setTintColor:[UIColor grayColor]];
search.frame = CGRectMake(0, 150, 320,50);
search.delegate = self;

UITextField *searchField=[search.subviews objectAtIndex:1];//Changed this line in ios 7
searchField.backgroundColor=[UIColor redColor];

UILabel *label=[[UILabel alloc] initWithFrame:CGRectMake(0, 0, 40, 40)];
label.text=@"Hello";
label.textColor=[UIColor greenColor];

searchField.rightView = label;
searchField.rightViewMode = UITextFieldViewModeAlways;

[self addSubView:search];

When i have Run the same code in ios 7(with xcode 7.0.2 fully updated), It was giving me error, after googling i got that hiearchy of searchbar to textfield has been changed, so i have modified my code as:

replaced commented line in above code with:

UITextField *searchField=[((UIView *)[search.subviews objectAtIndex:0]).subviews lastObject];

after doing this, it is not giving me any error(also checked the logs by printing the description of textfield and everything is working good), when i run it, it gives textfield with red background but the rightView's label is not shown to me. Now, can anyone help me how to show this rightview.

If you want to do this programatically then you have to declare UISearchBar object in your .h file.

UISearchBar  *searchBar;

And in your .m file you can code like:

- (void)viewDidLoad
{
    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.
    searchBar = [[UISearchBar alloc] init];
    [searchBar setTintColor:[UIColor grayColor]];
    searchBar.frame = CGRectMake(0, 150, 320,50);
    searchBar.delegate = self;

    [self.view addSubview:searchBar];
}

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

    UITextField *searchField;
    if ([[[UIDevice currentDevice] systemVersion] floatValue]<7.0)
        searchField=[searchBar.subviews objectAtIndex:1];
    else
        searchField=[((UIView *)[searchBar.subviews objectAtIndex:0]).subviews lastObject];

    searchField.backgroundColor=[UIColor redColor];

    UILabel *label=[[UILabel alloc] initWithFrame:CGRectMake(0, 0, 40, 40)];
    label.text=@"Hello";
    label.textColor=[UIColor greenColor];

    searchField.rightView = label;
    searchField.rightViewMode = UITextFieldViewModeAlways;
}

I think this will work for both iOS7 and prior versions of iOS7.
