*内购的用法,通过这个文件,基本上就可以实现. 在回调验证的时候需要注意.
交易结束时, 需要向 iTunes Store 验证票据信息. 分为两种, 这里我定义了两个宏
沙盒测试环境验证
#define SANDBOX @"https://sandbox.itunes.apple.com/verifyReceipt"
//正式环境验证
#define AppStore @"https://buy.itunes.apple.com/verifyReceipt"
- (void)completeTransaction:(SKPaymentTransaction *)transaction {
//系统IOS7.0以后，验证返回的数据
//得到的凭证只能使用 base64解码,规则这么定的
NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];
NSData *receipt = [NSData dataWithContentsOfURL:receiptURL];
if (!receipt) {
if (self.failTransaction) {
self.failTransaction (@"交易失败");
}
return;
}
// Create the JSON object that describes the request
NSString *receiptCode = [receipt base64EncodedStringWithOptions:0];
NSError *error;
NSDictionary *requestContents = @{
@"receipt-data": receiptCode
};
NSData *requestData = [NSJSONSerialization dataWithJSONObject:requestContents options:0 error:&error];
// Create a POST request with the receipt data.
NSURL *storeURL = [NSURL URLWithString:AppStore];
NSMutableURLRequest *storeRequest = [NSMutableURLRequest requestWithURL:storeURL];
[storeRequest setHTTPMethod:@"POST"];
[storeRequest setHTTPBody:requestData];
// Make a connection to the iTunes Store on a background queue.
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
[NSURLConnection sendAsynchronousRequest:storeRequest queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
if (connectionError) {
/* ... Handle error ... */
} else {
NSError *error;
NSDictionary *jsonResponse = [NSJSONSerialization JSONObjectWithData:data options:0 error:&error];
if (!jsonResponse) {//为空
if (self.failTransaction) {
self.failTransaction (@"验证失败");
}
} else {
[self checkPayForReciept:jsonResponse receipt:receiptCode];
}
}
}];
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}
/*! 通过返回的 jsonResponse 数据中的 status, 做判断, 验证票据信息, 是否正确
可参考
https://developer.apple.com/library/content/releasenotes/General/ValidateAppStoreReceipt/Chapters/ValidateRemotely.html
*/
- (void) checkPayForReciept:(NSDictionary *)jsonResponse receipt:(NSString *)receipt {
NSUInteger status = [[jsonResponse objectForKey:@"status"] integerValue];
NSString *message = @"";
switch (status) {
case 0: {//验证成功
NSString *temp = [NSString stringWithFormat:@"%@#",AppStore];
message = [temp stringByAppendingString:receipt];
} break;
case 21007://使用的是沙盒测试账号, 但是线上环境
{
NSString *temp = [NSString stringWithFormat:@"%@#",SANDBOX];
message = [temp stringByAppendingString:receipt];
}
break;
case 21008://使用的是线上账号, 但是沙盒测试环境
{
NSString *temp = [NSString stringWithFormat:@"%@#",AppStore];
message = [temp stringByAppendingString:receipt];
}
break;
default:
break;
}
if (self.purchaseBlock) {
self.purchaseBlock (message);
}
}
