您好，在执行react-native run-ios后，提示BUILD FAILED，具体信息如下：
./ReactNative/GitHubPopular/node_modules/react-native/Libraries/WebSocket/RCTSRWebSocket.m:494:3: error: ignoring return value of function declared with warn_unused_result attribute [-Werror,-Wunused-result] SecRandomCopyBytes(kSecRandomDefault, keyBytes.length, keyBytes.mutableBytes); ^~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ./ReactNative/GitHubPopular/node_modules/react-native/Libraries/WebSocket/RCTSRWebSocket.m:1334:5: error: ignoring return value of function declared with warn_unused_result attribute [-Werror,-Wunused-result] SecRandomCopyBytes(kSecRandomDefault, sizeof(uint32_t), (uint8_t *)mask_key); ^~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 2 errors generated._

在中文官网找到了答案:
将
SecRandomCopyBytes(kSecRandomDefault, keyBytes.length, keyBytes.mutableBytes);
改为
(void)SecRandomCopyBytes(kSecRandomDefault, keyBytes.length, keyBytes.mutableBytes);即可。
