将“ UISegmentedControl”的角半径设置为等于“ UISearchController”的角半径

Question

I have several boxes on a page and I would like them all the have the corner radius of the UISearchController also on that page.

I tried to set the corner radius of my segmented control equal to that of the search controller. However, _searchController.searchBar.layer.cornerRadius returns 0 instead of its actual value in both viewDidLoad and viewDidAppear .

I tried the textfield inside of the search bar, but it also returns 0 for its corner radius.

Answer 1

#define CornerRadius    6

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    [self.navigationController setNavigationBarHidden:YES];

    [self.userNameTextfield.layer setCornerRadius:CornerRadius];
    [self.userNameTextfield.layer setBorderColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"bg_login"]].CGColor];
    [self.userNameTextfield.layer setBorderWidth:1.0];
    [self.userNameTextfield.layer setMasksToBounds:YES];

    [self.passwordTextfield.layer setCornerRadius:CornerRadius];
    [self.passwordTextfield.layer setBorderColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"bg_login"]].CGColor];
    [self.passwordTextfield.layer setBorderWidth:1.0];
    [self.passwordTextfield.layer setMasksToBounds:YES];


    // Do any additional setup after loading the view, typically from a nib.
}

set both corner radius like this
