我的Xcode项目中有以下错误，我无法弄清楚如何纠正它。我试图保存并关闭Xcode并重新打开项目，但这不起作用。我收到以下信息：
使用未声明的标识符'gremoveads'和以下代码。
}
if (buttonIndex==2) {
bool bPaymentInQueue = NO;
for (SKPaymentTransaction *transaction in [SKPaymentQueue defaultQueue].transactions) {
if ([transaction.payment.productIdentifier isEqualToString:gRemoveads]) {
bPaymentInQueue = YES;
NSLog(@"Payment already in queue!");
break;
}
我也遇到了这个错误。使用未声明的标识符'gunlimitedcoins'和以下代码。
if (buttonIndex==0) {
bool bPaymentInQueue = NO;
for (SKPaymentTransaction *transaction in [SKPaymentQueue defaultQueue].transactions) {
if ([transaction.payment.productIdentifier isEqualToString:gUnlimitedCoins]) {
bPaymentInQueue = YES;
NSLog(@"Payment already in queue!");
break;
如何修复这两个未声明的标识符错误？

答案 0 :(得分：0)
你没有声明这些：
gRemoveads
和
gUnlimitedCoins
范围/块中缺少这些声明。
答案 1 :(得分：0)
看起来语句“transaction.payment.productIdentifier isEqualToString：gRemoveads”中的变量“gRemoveads”从未被声明或设置过。从计算机的角度来看，这个变量不存在。你知道这个变量是什么或它应该设置在哪里吗？
或者那些应该是字符串文字？与确切的文字“gRemoveads”一样。在这种情况下，请将其放在引号中。
