ios - Stripe iOS 更改后退按钮标题

Question

有办法改变 Stripe 取消按钮的标题吗？

我需要把它改成“Back”，事实上，“Back”更适合描述它的行为。

我以这种方式呈现 Controller :

let customerContext = STPCustomerContext(keyProvider: StripeClient.shared)
let paymentMethodsViewController = STPPaymentMethodsViewController(configuration: STPPaymentConfiguration.shared(), theme: STPTheme.default(), customerContext: customerContext, delegate: self as STPPaymentMethodsViewControllerDelegate)
let navigationController = UINavigationController(rootViewController: paymentMethodsViewController)
present(navigationController, animated: true)

转到 strip 文件中的 STPCoreViewController.m。

只需替换此方法

- (void)commonInitWithTheme:(STPTheme *)theme {
_theme = theme;

if (![self useSystemBackButton]) {
    self.cancelItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel
                                                                    target:self
                                                                    action:@selector(handleCancelTapped:)];

    self.stp_navigationItemProxy.leftBarButtonItem = self.cancelItem;
    }
}

与

- (void)commonInitWithTheme:(STPTheme *)theme {
_theme = theme;

if (![self useSystemBackButton]) {

    self.cancelItem = [[UIBarButtonItem alloc]
                                   initWithTitle:@"Back"
                                   style: UIBarButtonItemStylePlain
                                   target:self
                                   action:@selector(handleCancelTapped:)];

    self.stp_navigationItemProxy.leftBarButtonItem = self.cancelItem;
    }
}
