Ios6 在iOS 6和iOS 7中验证采购收据

Ios6 在iOS 6和iOS 7中验证采购收据,ios6,ios7,in-app-purchase,Ios6,Ios7,In App Purchase,我正在使用以下代码验证应用内购买收据: - (void) completeTransaction:(SKPaymentTransaction*) transaction { NSData* receipt = nil; // 1. Attempt <app receipt> first (iOS 7.x) NSBundle* mainBundle = [NSBundle mainBundle]; if ([mainBundle respon

我正在使用以下代码验证应用内购买收据:

- (void) completeTransaction:(SKPaymentTransaction*) transaction
{   
    NSData* receipt = nil;

    // 1. Attempt <app receipt> first (iOS 7.x)

    NSBundle* mainBundle = [NSBundle mainBundle];

    if ([mainBundle respondsToSelector:@selector(appStoreReceiptURL)]) {

        NSURL* appStoreReceiptURL = [mainBundle appStoreReceiptURL]; // <- CRASH

        receipt = [NSData dataWithContentsOfURL:appStoreReceiptURL];
    }

    // 2. Fallback to <transaction receipt> (iOS < 7.0)
    if (!receipt) {    
        receipt = [transaction transactionReceipt];
    }

    // 3. Have server verify it with iTunes:    
    [self verifyReceipt:receipt forTransaction:transaction];
}
-(void)completeTransaction:(SKPaymentTransaction*)交易
{   
NSData*接收=无;
//1.先尝试(iOS 7.x)
NSBundle*mainBundle=[NSBundle mainBundle];
if([mainBundle respondsToSelector:@selector(appStoreReceiptURL)]){

NSURL*appStoreReceiptURL=[mainBundle appStoreReceiptURL];//是,如果使用此appStoreReceiptURL方法,您应该直接检查版本号。 appStoreReceiptURL

在iOS中,使用以下代码检测此方法是否可用:

if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1) {
   // Load resources for iOS 6.1 or earlier
} else {
   // Load resources for iOS 7 or later
}
if(楼层(NSFoundationVersionNumber)
