恢复购买 -->如果该appid购买过这个商品 可以恢复
先执行第一步 然后接下来
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];//发起请求
请求的回调
#pragma mark -- 恢复交易处理
- (void)restoreTransaction:(SKPaymentTransaction *)transaction {
NSLog(@" 交易恢复处理ing");
}
//恢复失败
-(void) paymentQueue:(SKPaymentQueue *) paymentQueue restoreCompletedTransactionsFailedWithError:(NSError *)error{
[self hidden];
NSLog(@"-------paymentQueue----");
}
*如果用户已经购买过这个商品 会走 *
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions 会调 这个回调在上面写过了 这里就不在说了
