我是 cocos2d 的新手,所以我的应用内购买类助手有问题。我在 Cocoa Touch 中编写了游戏,并且这个类运行良好,但我现在正在 Cocos2d 中编写相同的游戏,问题出在 NSString 上。
这里有一些片段。
当我单击某个按钮时,首先调用此方法。如您所见,是带有一些字符串参数completeIdentifier
的简单字符串。bundleIdentifier
没关系,在这个地方我可以记录这个completeIdentifier
。
- (void)prepareToPurchaseItemWithIdentifier:(NSString *)aIdentifier showAlertWithTitle:(NSString *)title description:(NSString *)description delegate:(id)aDelegate{
self.delegate = aDelegate;
identifier = aIdentifier;
completeIdentifier = [NSString stringWithFormat:@"%@.%@", [[NSBundle mainBundle] bundleIdentifier], aIdentifier];
askToPurchase = [[UIAlertView alloc] initWithTitle:title message:description delegate:self cancelButtonTitle:nil otherButtonTitles:@"Later", @"Yes", nil];
askToPurchase.delegate = self;
[askToPurchase show];
}
下一个方法是UIAlertViewDelegate
方法。当我从第一种方法单击YES
时调用。alertView
#pragma mark - UIAlertViewDelegate Methods
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
NSLog(@"%@", completeIdentifier);
if (alertView == askToPurchase) {
NSLog(@"[TSIAPHelper] Clicked YES. Prepare...");
if ([SKPaymentQueue canMakePayments]) {
NSLog(@"[TSIAPHelper] Prepare to purchase [%@].",completeIdentifier);
SKProductsRequest *request =[[SKProductsRequest alloc] initWithProductIdentifiers:
[NSSet setWithObject:completeIdentifier]];
request.delegate = self;
[request start];
pleaseWait = [[UIAlertView alloc] initWithTitle:@"Please wait..." message:@"" delegate:self cancelButtonTitle:nil otherButtonTitles:nil, nil];
UIActivityIndicatorView *activity = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];
[activity startAnimating];
[pleaseWait addSubview:activity];
activity.frame = CGRectMake(125, 50, 36, 36);
[pleaseWait show];
}
else {
NSLog(@"[TSIAPHelper] Purchase [FAILURE]. Prohibited by Parentar Control or something like that.");
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Prohibited." message:@"Parental Control is enabled, cannot make a purchase. Turn off and try again." delegate:self cancelButtonTitle:nil otherButtonTitles:@"Ok", nil];
[alert show];
}
}
}
问题是:无论何时何地我想记录变量,completeIdentifier
我都会在选定的行上崩溃:0x39e965d0: ldr r3, [r4, #8]
但我不知道那是什么意思。并选择了这一行:
NSLog(@"%@", completeIdentifier);
我该如何解决?在 Cocoa Touch 中运行良好。当我使用 cocos2d 时不是。
