如何解决Restkit：本机 iOS Swift 应用程序在 Xcode 12.5 中崩溃
当 public class HostingGameActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_hosting_game);
FirebaseAuth mAuth = FirebaseAuth.getInstance();
AtomicBoolean startGame = new AtomicBoolean(false);
BackgroundTasks taskExecutor = new BackgroundTasks();
Button startGame_button = findViewById(R.id.startGame_button);
startGame_button.setBackground(new ColorDrawable(Color.GRAY));
updateDataInBackground(startGame,taskExecutor,mAuth);
startGame_button.setonClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(startGame.get()){
Intent start_game_intent = new Intent(HostingGameActivity.this,MapsActivity.class);
startActivity(start_game_intent);
taskExecutor.shutdown();
}
}
});
}
void updateDataInBackground(AtomicBoolean startGame,BackgroundTasks taskExecutor,FirebaseAuth mAuth) {
BackgroundTasks.executor.execute(()->{
List<String> host_data_request = taskExecutor.getRequest(mAuth.getUid(),Requests.Host_Data);
while(!startGame.get()) {
try {
startGame.set(updateText(host_data_request));
host_data_request = taskExecutor.getRequest(mAuth.getUid(),Requests.Host_Data);
} catch (ExecutionException e) {
e.printstacktrace();
} catch (InterruptedException e) {
e.printstacktrace();
}
}
});
}
boolean updateText(List<String> host_data_request) throws ExecutionException,InterruptedException {
Future<Boolean> result = BackgroundTasks.executor.submit(()-> {
//get views and buttons
Button startGame_button = findViewById(R.id.startGame_button);
TextView players_counter_text = findViewById(R.id.player_counter_text);
TextView players_display_text = findViewById(R.id.players_display_text);
//extract You text
String you_text = players_display_text.getText().toString().substring(0,3);
StringBuilder builder = new StringBuilder();
//count players connected
int player_counter = 1;
//clear text and set it new text to the view
builder.append(you_text + "\n");
if(host_data_request != null) {
for (String playerName : host_data_request) {
player_counter++;
System.out.println(playerName);
String[] row_values = playerName.split(" ");
builder.append(row_values[1]).append("\n");
}
players_display_text.setText(builder.toString());
}
players_counter_text.setText("Players: " + player_counter);
if(player_counter > 5) {
//set Button color if the game can start
startGame_button.setBackground(new ColorDrawable(Color.GREEN));
return true;
}
return false;
});
return result.get();
}
尝试映射属性值时，它会抛出异常：
MKMapperOperation
代码 11.xx 运行良好。当我更新到 Xcode 12 时崩溃开始了。
我尝试了以下但没有运气：
RestKit RKObjectMapping Swift Optional
我也在 Restkit git repo 上创建了以下问题。但从那里没有运气：
