我想在我的React Native项目中使用react-native-fbsdk记录事件，我通过该库的指令完成所有操作。但是当我尝试在iOS模拟器上启动它时出现错误：
undefined不是对象（评估'AppEventsLogger.logEvent'）

这似乎是react-native-fbsdk中的问题。参考以下链接

就我而言，react-native run-android有效。链接后也运行 @Test
void test() {
try {
String filePath = "C:/Users/Administrator/Desktop/backupv2/imageMgmt/asdf/";
File directory = new File(filePath);
if (!directory.exists()) {
Files.createDirectories(Paths.get(filePath));
directory.mkdir();
}
String val = "space";
File imageValue = new File("C:/Users/Administrator/Desktop/backupv2/" + val + ".gif");
FileInputStream imageInFile = new FileInputStream(imageValue);
byte[] imageByte= new byte[(int) (imageValue.length())];
imageInFile.read(imageByte);
String base64String = Base64.getEncoder().encodeToString(imageByte);
//Path destinationFile = Paths.get("https://172.20.188.63:8553/m/" + val + ".gif");
Path destinationFile = Paths.get(filePath + val + ".gif");
byte[] decoded = Base64.getDecoder().decode(base64String);
System.out.println("Path: " + destinationFile.toString());
Files.write(destinationFile, decoded);
System.out.println("Upload success!");
}catch(Exception e) {
}
}
。
希望这会有所帮助。
