发送订阅信息

您可以用 Adjust SDK 记录 App Store 的订阅，并验证这些订阅是否有效。用户购买订阅后，创建一个包含细节的 ADJSubscription 实例。

1. Instantiate a subscription object

- (nullable id)initWithPrice:(nonnull NSDecimalNumber *)price
                    currency:(nonnull NSString *)currency
               transactionId:(nonnull NSString *)transactionId;

要开始设置，先创建一个包含订阅购买细节的订阅对象。为此，请使用 initWithPrice 方法初始化一个 ADJSubscription 对象。传递以下参数：

参数	数据类型	描述
`price`	`NSDecimalNumber`	订阅价格
`currency`	`NSString`	订阅使用的币种。此信息格式为 `priceLocale` 对象的 `currencyCode`。
`transactionId`	`NSString`	您的交易 ID
`receipt`	`NSString`	收据信息

Swift
Objective-C

1
let subscription = ADJSubscription(
2
    price: price,
3
    currency: currency,
4
    transactionId: transactionId)

1
ADJSubscription *subscription = [[ADJSubscription alloc] initWithPrice:price
2
                                                              currency:currency
3
                                                         transactionId:transactionId];

Record the purchase date

- (void)setTransactionDate:(nonnull NSDate *)transactionDate;

您可以记录用户购买订阅的日期。SDK 会返回该数据用于报告。请使用时间戳调用 setTransactionDate 方法，记录该信息。

Swift
Objective-C

1
let subscription = ADJSubscription(
2
    price: price,
3
    currency: currency,
4
    transactionId: transactionId,)
5
// ...
6
subscription.setTransactionDate(transactionDate)

1
ADJSubscription *subscription = [[ADJSubscription alloc] initWithPrice:price
2
                                                              currency:currency
3
                                                         transactionId:transactionId];
4
/// ...
5
[subscription setTransactionDate:transactionDate];

Record the purchase region

- (void)setSalesRegion:(nonnull NSString *)salesRegion;

您可以记录用户购买订阅的地区。为此，请在订阅对象上调用 setSalesRegion 方法并将国家代码作为 NSString 传递。此信息格式需为 priceLocale 对象的 countryCode。

Swift
Objective-C

1
let subscription = ADJSubscription(
2
    price: price,
3
    currency: currency,
4
    transactionId: transactionId)
5
// ...
6
subscription.setSalesRegion(salesRegion)

1
ADJSubscription *subscription = [[ADJSubscription alloc] initWithPrice:price
2
                                                              currency:currency
3
                                                         transactionId:transactionId];
4
/// ...
5
[subscription setSalesRegion:salesRegion];

Add callback parameters

- (void)addCallbackParameter:(nonnull NSString *)key value:(nonnull NSString *)value;

您可以向订阅对象附加回传参数。SDK 会将这些参数附加至您的回传 URL。要添加回传参数，请在订阅对象上调用 addCallbackParameter 方法。多次调用该方法可添加多个回传参数。

Swift
Objective-C

1
let subscription = ADJSubscription(
2
    price: price,
3
    currency: currency,
4
    transactionId: transactionId)
5
// ...
6
subscription.addCallbackParameter("key1", value: "value1")
7
subscription.addCallbackParameter("key2", value: "value2")

1
ADJSubscription *subscription = [[ADJSubscription alloc] initWithPrice:price
2
                                                              currency:currency
3
                                                         transactionId:transactionId];
4
/// ...
5
[subscription addCallbackParameter:@"key1" value:@"value1"];
6
[subscription addCallbackParameter:@"key2" value:@"value2"];

Add partner parameters

- (void)addPartnerParameter:(nonnull NSString *)key value:(nonnull NSString *)value;

您可以向订阅对象附加合作伙伴参数。用户购买订阅时，SDK 会将这些参数发送至 Adjust 服务器。Adjust 服务器会将此信息转发至您的合作伙伴。要添加合作伙伴参数，请在您的订阅对象上调用addPartnerParameter方法。多次调用该方法可添加多个合作伙伴参数。

Swift
Objective-C

1
let subscription = ADJSubscription(
2
    price: price,
3
    currency: currency,
4
    transactionId: transactionId)
5
// ...
6
subscription.addParameterParameter("key1", value: "value1")
7
subscription.addParameterParameter("key2", value: "value2")

1
ADJSubscription *subscription = [[ADJSubscription alloc] initWithPrice:price
2
                                                              currency:currency
3
                                                         transactionId:transactionId];
4
/// ...
5
[subscription addParameterParameter:@"key1" value:@"value1"];
6
[subscription addParameterParameter:@"key2" value:@"value2"];

2. Send subscription information

+ (void)trackSubscription:(nonnull ADJSubscription *)subscription;

设置好订阅对象后，您就可以使用 Adjust SDK 将其发送给 Adjust 了。将已完成对象传送至 trackSubscription 方法，以记录用户订阅购买。

Swift
Objective-C

1
let subscription = ADJSubscription(
2
   price: price,
3
   currency: currency,
4
   transactionId: transactionId)
5

6
subscription.setTransactionDate(transactionDate)
7
subscription.setSalesRegion(salesRegion)
8

9
// Add callback parameters
10

11
subscription.addCallbackParameter("key1", value: "value1")
12
subscription.addCallbackParameter("key2", value: "value2")
13

14
// Add partner parameters
15

16
subscription.addPartnerParameter("key1", value: "value1")
17
subscription.addCallbackParameter("key2", value: "value2")
18

19
Adjust.trackSubscription(subscription)

1
ADJSubscription *subscription = [[ADJSubscription alloc] initWithPrice:price
2
                                                            currency:currency
3
                                                         transactionId:transactionId];
4
[subscription setTransactionDate:transactionDate];
5
[subscription setSalesRegion:salesRegion];
6

7
/// Add callback parameters
8
[subscription addCallbackParameter:@"key1" value:@"value1"];
9
[subscription addCallbackParameter:@"key2" value:@"value2"];
10

11
/// Add partner parameters
12
[subscription addPartnerParameter:@"key1" value:@"value1"];
13
[subscription addPartnerParameter:@"key2" value:@"value2"];
14

15
[Adjust trackSubscription:subscription];
