但是,如何检查是否启用了应用程序内购买？

解决方法 这对你有帮助：

if ([SKPaymentQueue canMakePayments]) {     // start adding the payment to the payment queue} else {     // handle the restriction}

它是关于canMakePayments类方法的SKPaymentQueue类引用：

YES if the user is allowed to authorize payment. NO if they do not have permission.

以及对同一方法的进一步说明：

An iPhone can be restricted from accessing the Apple App Store. For example,parents can restrict their children’s ability to purchase additional content. Your application should confirm that the user is allowed to authorize payments before adding a payment to the queue. Your application may also want to alter its behavior or appearance when the user is not allowed to authorize payments.
