Question

我正在尝试从AdMob的本机iOS代码中实现回调，这是我的代码， com_manyukhin_cerebrate_words_synonyms_NativeInterstitialAdsInterfaceImpl.h：

#include "CodenameOne_GLViewController.h"
#include "com_manyukhin_cerebrate_words_synonyms_WordsSynonyms.h"

com_manyukhin_cerebrate_words_synonyms_NativeInterstitialAdsInterfaceImpl.m：

#import "com_manyukhin_cerebrate_words_synonyms_NativeInterstitialAdsInterfaceImpl.h"

- (void) interstitialDidDismissScreen:(GADInterstitial *)ad {
    com_manyukhin_cerebrate_words_synonyms_WordsSynonyms_onInterstitialClosed__(CN1_THREAD_STATE_PASS_SINGLE_ARG);
}

但是我遇到了涉及CN1_THREAD_STATE_PASS_SINGLE_ARG的定义的编译错误：

/var/folders/p_/xlvwhg4101z8r81_nl13cds80000gn/T/build6871177334585892440xxx/dist/WordsSynonyms-src/com_manyukhin_cerebrate_words_synonyms_NativeInterstitialAdsInterfaceImpl.m:59:78: error: use of undeclared identifier 'threadStateData'
        com_manyukhin_cerebrate_words_synonyms_WordsSynonyms_onInterstitialClosed__(CN1_THREAD_STATE_PASS_SINGLE_ARG);
                                                                                    ^

#define CN1_THREAD_STATE_PASS_SINGLE_ARG threadStateData
                                         ^

有什么解决办法吗？

有趣的是，同一.m文件中的以下代码（不同的宏）不会触发错误：

- (void) interstitial:(GADInterstitial *)ad didFailToReceiveAdWithError:(GADRequestError *)error {  
    com_manyukhin_cerebrate_words_synonyms_WordsSynonyms_onInterstitialFaliedToLoad___int(CN1_THREAD_GET_STATE_PASS_ARG -1);
}

这些定义如下：

#define CODENAME_ONE_THREAD_STATE struct ThreadLocalData* threadStateData

#define CN1_THREAD_STATE_SINGLE_ARG CODENAME_ONE_THREAD_STATE
#define CN1_THREAD_STATE_MULTI_ARG CODENAME_ONE_THREAD_STATE,
#define CN1_THREAD_STATE_PASS_ARG threadStateData,
#define CN1_THREAD_STATE_PASS_SINGLE_ARG threadStateData
#define CN1_THREAD_GET_STATE_PASS_ARG getThreadLocalData(),
#define CN1_THREAD_GET_STATE_PASS_SINGLE_ARG getThreadLocalData()

因此，您需要使用CN1_THREAD_GET_STATE_PASS_SINGLE_ARG。我不确定为什么在同一文件中不会失败。解决此呼叫后，它可能会失败。

iOS本机代码编译错误，使用未声明的标识符'threadStateData'，从宏'CN1_THREAD_STATE_PASS_SINGLE_ARG'扩展
