首先，先上stripe官方的链接，官方其实写的已经是很细致细致了，对于新手来说也是很友好的。
接下来，话不多说，上活！
第一步，pod 依赖库
用CocoaPods将Stripe依赖库pod下来，因为我用的oc，所以并没有去pod官方给的StripePaymentsUI，找了和StripePaymentsUI相关的demo，发现里面都是用swift写的，然后我也一直pod不下来，所以我后来放弃了，如果有的小伙伴想用的话，可以试试。（pod 'StripePaymentsUI'）。
直接 pod 'Stripe'
第二步，准备相关的key（通常都是问后台要，因为stripe支付基本都是后端来完成的，哈哈）
这里所说的key是在stripe那边注册账号，申请的对应的测试key以及正式发布key。开发的时候我们用测试的key就可以，因为官方给了对应的测试卡号，可完成测试环节，非常友好。
第三步，代码实现
1，我在PrefixHeader的全局文件里面定义了两个key，
#define STRIPE_TEST_PK @"此处为测试的公钥"。
#define STRIPE_LIVE_PK @"此处为正式环境的公钥"。
2，在AppDelegate.m中完成Stripe的初始化配置
1）倒入依赖库的头文件#import <Stripe.h>
2）初始化配置
// 配置stripe支付
[Stripe setDefaultPublishableKey:STRIPE_TEST_PK];
上面这行代码可以放在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions {}这个方法里就行。以上就是完成依赖库的简单初始化了。
3，支付调用，我这里因为没有StripePaymentsUI可用，然后是自己写的alert弹窗，用的Stripe里面的STPPaymentCardTextField这个控件，实现的信用卡信息的收集。
在支付调用的类引入头文件
// Stripe支付
#import <Stripe.h>
在需要调用支付的按钮点击事件处，首先要请求后段服务接口，这个接口需要给我们返回所需的ClientSecret，字段名字后台随便定义。
我这边是在程序里面定义了一个属性变量，用这个变量来存储这个字符串@property (nonatomic,copy) NSString *paymentIntentClientSecret;
在请求后台接口成功的时候给这个变量赋值，后面需要用。同时在接口请求成功的时候，弹出我们自定义的alert。参考代码如下：
NSDictionary *data_dic = [NSDictionary dictionaryWithDictionary:responseObject[@"data"]];
weakSelf.paymentIntentClientSecret = [NSString stringWithFormat:@"%@",data_dic[@"paymentIntent"]];
if(!weakSelf.PayAlert) {
UIView*pay_alert = [weakSelfshowPayAlert];
[appDelegate.windowaddSubview:pay_alert];
weakSelf.PayAlert= pay_alert;
}
弹窗如下图：
如何自定义alert用下面的代码作为参考。定义了一个@property (nonatomic,weak) UIView *PayAlert;
// showPayAlert
- (UIView *)showPayAlert{
UIView *payAlert = [[UIView alloc] initWithFrame:CGRectMake(0, 0, Screen_Width, Screen_Height)];
payAlert.backgroundColor=ClearColor;
UIView *bla_view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, Screen_Width, Screen_Height-300)];
bla_view.backgroundColor = ColorWithRGB(@"#000000", 0.5);
[payAlertaddSubview:bla_view];
UITapGestureRecognizer *bla_view_tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(bla_view_tap_action)];
[bla_viewaddGestureRecognizer:bla_view_tap];
UIView*whi_view = [[UIViewalloc]initWithFrame:CGRectMake(0,Screen_Height-300,Screen_Width, 300)];
whi_view.backgroundColor=white_Color;
[payAlertaddSubview:whi_view];
UIButton *close_btn = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 50, 50)];
[close_btnsetImage:[UIImage imageNamed:@"SDPay_close"] forState:UIControlStateNormal];
[whi_viewaddSubview:close_btn];
[close_btnaddTarget:self action:@selector(close_btn_action) forControlEvents:UIControlEventTouchUpInside];
UILabel *top_lab = [[UILabel alloc] initWithFrame:CGRectMake(20, CGRectGetMaxY(close_btn.frame), Screen_Width-40, 20)];
top_lab.text = FGGetStringWithKeyFromTable(@"tpl127", @"Localizable");
top_lab.font = [UIFont systemFontOfSize:18];
top_lab.textColor=black_Color;
[whi_viewaddSubview:top_lab];
UILabel *bom_lab = [[UILabel alloc] initWithFrame:CGRectMake(20, CGRectGetMaxY(top_lab.frame)+10, Screen_Width-40, 20)];
bom_lab.text = FGGetStringWithKeyFromTable(@"tpl128", @"Localizable");
bom_lab.font = [UIFont systemFontOfSize:15];
bom_lab.textColor = colorWithHexString(@"#666666");
[whi_viewaddSubview:bom_lab];
STPPaymentCardTextField *cardTextField = [[STPPaymentCardTextField alloc] initWithFrame:CGRectMake(20, 110, Screen_Width-40, 40)];
cardTextField.numberPlaceholder = FGGetStringWithKeyFromTable(@"tpl132", @"Localizable");
cardTextField.expirationPlaceholder = FGGetStringWithKeyFromTable(@"tpl130", @"Localizable");
cardTextField.postalCodePlaceholder = FGGetStringWithKeyFromTable(@"tpl131", @"Localizable");
self.cardTextField= cardTextField;
[whi_viewaddSubview:cardTextField];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame=CGRectMake(20,CGRectGetMaxY(cardTextField.frame)+30,Screen_Width-40, 50);
button.layer.cornerRadius= 5;
button.backgroundColor = [UIColor systemBlueColor];
button.titleLabel.font = [UIFont systemFontOfSize:22];
[buttonsetTitle:[NSString stringWithFormat:@"%@ %@",FGGetStringWithKeyFromTable(@"tpl129", @"Localizable"),self.money_lab.text] forState:UIControlStateNormal];
[buttonaddTarget:self action:@selector(pay) forControlEvents:UIControlEventTouchUpInside];
self.payButton= button;
[whi_viewaddSubview:button];
returnpayAlert;
}
- (void)bla_view_tap_action{
[appDelegate.window endEditing:YES];
}
- (void)close_btn_action{
[appDelegate.window endEditing:YES];
if(self.PayAlert) {
[self.PayAlert.subviews makeObjectsPerformSelector:@selector(removeFromSuperview)];
[self.PayAlert removeFromSuperview];
self.PayAlert=nil;
}
}
为了更好的体验，我在这个类里面监听了键盘的弹出事件
- (void)addObserve{
// 增加监听，当键盘出现或改变时收出消息
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardWillShow:)
name:UIKeyboardWillShowNotification
object:nil];
// 增加监听，当键退出时收出消息
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardWillHide:)
name:UIKeyboardWillHideNotification
object:nil];
}
#pragma mark- 监听键盘的高度
// 当键盘出现或改变时调用
- (void)keyboardWillShow:(NSNotification*)aNotification{
// 获取键盘的高度
NSDictionary*userInfo = [aNotificationuserInfo];
NSValue*aValue = [userInfoobjectForKey:UIKeyboardFrameEndUserInfoKey];
CGRectkeyboardRect = [aValueCGRectValue];
CGFloatheight = keyboardRect.size.height;
if(self.PayAlert) {
self.PayAlert.y= -height;
}
}
// 当键退出时调用
- (void)keyboardWillHide:(NSNotification*)aNotification{
if(self.PayAlert) {
self.PayAlert.y= 0;
}
}
点击支付弹窗上的支付按钮的点击事件实现：
- (void)pay{
[appDelegate.window endEditing:YES];
if (!self.paymentIntentClientSecret) {
NSLog(@"PaymentIntent hasn't been created");
return;
}
[MBProgressHUD showHUDAddedTo:appDelegate.window animated:YES];
//我这里是直接使用Stripe自带的STPPaymentCardTextField收集的卡参数
STPPaymentMethodParams *paymentMethodParams = [STPPaymentMethodParams paramsWithCard:self.cardTextField.cardParams billingDetails:nil metadata:nil];
//服务器传递过来的ClientSecret
STPPaymentIntentParams *paymentIntentParams = [[STPPaymentIntentParams alloc] initWithClientSecret:self.paymentIntentClientSecret];
paymentIntentParams.paymentMethodParams= paymentMethodParams;
// paymentIntentParams.savePaymentMethod = @YES;
//自己设置的urlScheme: your-app://stripe-redirect
//paymentIntentParams.returnURL = @"xxx://xxx.stripe.com";
MJWeakSelf
// Submit the payment
STPPaymentHandler *paymentHandler = [STPPaymentHandler sharedHandler];
// STPAuthenticationContext 需要实现一下<STPAuthenticationContext>
[paymentHandlerconfirmPayment:paymentIntentParams withAuthenticationContext:self completion:^(STPPaymentHandlerActionStatus status, STPPaymentIntent *paymentIntent, NSError *error) {
dispatch_async(dispatch_get_main_queue(), ^{
[MBProgressHUD hideAllHUDsForView:appDelegate.window animated:YES];
switch(status) {
case STPPaymentHandlerActionStatusFailed: {// 失败
NSLog(@"STPPaymentHandlerActionStatusFailed %@",error.localizedDescription ?: @"");
[MBProgressHUD showMessage:FGGetStringWithKeyFromTable(@"tpl88", @"Localizable") toView:appDelegate.window delay:2];
break;
}
case STPPaymentHandlerActionStatusCanceled: {// 取消
NSLog(@"STPPaymentHandlerActionStatusCanceled %@",error.localizedDescription ?: @"");
[MBProgressHUD showMessage:FGGetStringWithKeyFromTable(@"tpl89", @"Localizable") toView:appDelegate.window delay:2];
break;
}
case STPPaymentHandlerActionStatusSucceeded: {// 成功
NSLog(@"STPPaymentHandlerActionStatusSucceeded %@",paymentIntent.description ?: @"");
[MBProgressHUD showMessage:FGGetStringWithKeyFromTable(@"tpl87", @"Localizable") toView:appDelegate.window delay:2.5];
[weakSelfclose_btn_action];
// 支付成功后代码业务逻辑可在这里编写
// 。。。。。
break;
}
default:
break;
}
});
}];
}
# pragma mark STPAuthenticationContext协议实现
- (UIViewController *)authenticationPresentingViewController {
return self;
}
到这里简单的oc版本的stripe支付就完成了，希望可以帮助你解惑，程序之路任重道远，疫情后时代，希望山河无恙，每个人都健健康康的。
