- (void) recordTransaction: (SKPaymentTransaction *) transaction {
    NSDictionary * receipt = [transaction.transactionReceipt dictionaryFromAppleResponse];
    NSDictionary * purchaseInfo = [[NSData dataFromBase64String: [receipt objectForKey: @"purchase-info"]] dictionaryFromAppleResponse];

    NSURL * url = [NSURL URLWithString: @"http://..."];

    ASIFormDataRequest * request = [ASIFormDataRequest requestWithURL: url];
    [request setDelegate: self];

    [request setPostValue: [NSNumber numberWithBool: YES] forKey: @"upload"];
    [request setPostValue: [[[NSBundle mainBundle] infoDictionary] objectForKey: @"CFBundleDisplayName"] forKey: @"app_id"];
    [request setPostValue: [receipt descriptionInStringsFileFormat] forKey: @"receipt"];
    [request setPostValue: [purchaseInfo descriptionInStringsFileFormat] forKey: @"purchase_info"];

    [WTFeedbackView switchToProgressView];
    [request setUploadProgressDelegate: [WTFeedbackView class]];

    NSLog(@"Before -startAsynchronous call.");
    [request startAsynchronous];
    NSLog(@"After  -startAsynchronous call.");
}

操作文件数据 -dictionaryFromAppleResponse 返回一个 NSDictionary . 我不明白为什么会出现以下错误:

Error Domain=ASIHTTPRequestErrorDomain Code=10 "NSInvalidArgumentException" UserInfo=0x19eb00 {NSLocalizedFailureReason=+[NSInvocation invocationWithMethodSignature:]: method signature argument cannot be nil, NSUnderlyingError=0x19eae0 "The operation couldnât be completed. (ASIHTTPRequestErrorDomain error 10.)", NSLocalizedDescription=NSInvalidArgumentException}

如果您在objc\u exception\u throw上添加断点,这将有助于您获得更多关于它到底哪里出错的信息(如果这样做了,请向问题添加回溯)。

假设错误来自ASIHTTPRequest本身,它使用NSInvocation与它的委托进行通信。我怀疑你代码里的这一行:

[request setUploadProgressDelegate: [WTFeedbackView class]];

我不确定是否可以将progress委托设置为类,我一直认为它必须是一个实际的对象—也许尝试删除它,我怀疑它会使错误消失。
