dependencies: [ .package(url: "https://github.com/braintree/braintree-ios-drop-in", from: "9.14.0")]
复制代码
CocoaPods
pod 'BraintreeDropIn'
复制代码
系统要求
iOS 12.0+
Xcode 15.0+
Swift 5.9+
使用说明
基本集成
import BraintreeDropIn
// 初始化Drop-in控制器let dropInRequest = BTDropInRequest()dropInRequest.cardholderNameSetting = .requireddropInRequest.vaultCard = true
let dropIn = BTDropInController(authorization: "your_client_token", request: dropInRequest) { (controller, result, error) in if let error = error { print("Error: \(error.localizedDescription)") } else if let result = result { // 处理支付结果 print("Payment method type: \(result.paymentMethodType)") print("Payment description: \(result.paymentDescription)") } controller.dismiss(animated: true)}
// 呈现Drop-in界面present(dropIn!, animated: true)
复制代码
UI 自定义示例
let uiCustomization = BTDropInUICustomization(colorScheme: .light)uiCustomization.fontFamily = "Helvetica"uiCustomization.boldFontFamily = "Helvetica-Bold"uiCustomization.tintColor = .systemBlue
let dropInRequest = BTDropInRequest()dropInRequest.uiCustomization = uiCustomization
复制代码
获取最近支付方式
BTDropInResult.mostRecentPaymentMethod(forClientToken: clientToken) { result, error in if let result = result { // 显示最近使用的支付方式 let paymentIcon = result.paymentIcon let description = result.paymentDescription }}
复制代码
核心代码
支付表单控制器
// BTCardFormViewController.h@interface BTCardFormViewController : BTDropInBaseViewController <UITextFieldDelegate>
@property (nonatomic, strong, readonly) BTUIKCardNumberFormField *cardNumberField;@property (nonatomic, strong, readonly) BTUIKCardholderNameFormField *cardholderNameField;@property (nonatomic, strong, readonly) BTUIKExpiryFormField *expirationDateField;@property (nonatomic, strong, readonly) BTUIKSecurityCodeFormField *securityCodeField;
// 如果表单有效，返回BTCardRequest@property (nonatomic, strong, nullable, readonly) BTCardRequest *cardRequest;
@end
复制代码
UI 定制配置
// BTDropInUICustomization.m- (instancetype)initWithColorScheme:(BTDropInColorScheme)colorScheme { if (self = [super init]) { _useBlurs = YES; _postalCodeFormFieldKeyboardType = UIKeyboardTypeDefault;
switch(colorScheme) { case BTDropInColorSchemeLight: _barBackgroundColor = UIColor.whiteColor; _formBackgroundColor = [UIColor btuik_colorFromHex:@"EFEFF4" alpha:1.0]; _primaryTextColor = UIColor.blackColor; _secondaryTextColor = [UIColor btuik_colorFromHex:@"3C3C43" alpha:1.0]; break; case BTDropInColorSchemeDark: _barBackgroundColor = [UIColor btuik_colorFromHex:@"222222" alpha:1.0]; _formBackgroundColor = [UIColor btuik_colorFromHex:@"222222" alpha:1.0]; _primaryTextColor = UIColor.whiteColor; _secondaryTextColor = [UIColor btuik_colorFromHex:@"EBEBF5" alpha:1.0]; break; default: // dynamic if (@available(iOS 13, *)) { _barBackgroundColor = UIColor.systemBackgroundColor; _formBackgroundColor = UIColor.systemGroupedBackgroundColor; _primaryTextColor = UIColor.labelColor; _secondaryTextColor = UIColor.secondaryLabelColor; } } } return self;}
复制代码
支付方式处理
// BTPaymentMethodNonce+DropIn.m- (NSString *)paymentDescription { if ([self isKindOfClass:[BTCardNonce class]]) { return ((BTCardNonce *)self).lastFour; } else if ([self isKindOfClass:[BTPayPalAccountNonce class]]) { return ((BTPayPalAccountNonce *)self).email; } else if ([self isKindOfClass:[BTVenmoAccountNonce class]]) { return ((BTVenmoAccountNonce *)self).username; } else if ([self isKindOfClass:[BTApplePayCardNonce class]]) { return @"Apple Pay"; } else { return @""; }}
复制代码
基础视图控制器
// BTDropInBaseViewController.m- (instancetype)initWithAPIClient:(BTAPIClient *)apiClient request:(BTDropInRequest *)request { if (self = [super init]) { self.apiClient = apiClient; _dropInRequest = request; } return self;}
- (void)loadConfiguration { [self.apiClient fetchOrReturnRemoteConfiguration:^(BTConfiguration *configuration, NSError *error) { self.configuration = configuration; [self configurationLoaded:configuration error:error]; }];}
