將“ UISegmentedControl”的角半徑設置為等於“ UISearchController”的角半徑

Question

我在頁面上有幾個框，我希望它們在該頁面上都具有UISearchController的角半徑。

我試圖將分段控件的角半徑設置為等於搜索控制器的角半徑。 但是， _searchController.searchBar.layer.cornerRadius返回0而不是viewDidLoad和viewDidAppear中的實際值。

我嘗試了搜索欄內的文本字段，但它的拐角半徑也返回0 。

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.
}

像這樣設置兩個拐角半徑
