iOS native 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

Question

我正在尝试从 AdMob 的 native iOS 代码实现回调，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);
}

但我遇到了引用 CN1_THREAD_STATE_PASS_SINGLE_ARG 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);
}

Answer 1

这些是这样定义的:

#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()

所以你需要使用CN1_THREAD_GET_STATE_PASS_SINGLE_ARG。我不确定为什么在同一个文件中不会失败。一旦您修复此调用，它可能会失败。
