iOS - 在異常處理程序中發送Web請求失敗

在我的應用程序中引發異常，我試圖在此處理它。意圖是打電話給我們的服務器，這是不成功的。我已經在try/catch語句中隔離了服務器調用，以查看是否引發了另一個異常，但從我的日誌中可以看到沒有引發額外的異常。是否有可能從異常處理程序發送Web請求或由於某種原因導致進程中斷？iOS - 在異常處理程序中發送Web請求失敗

void uncaughtExceptionHandler(NSException *exception) { 
    [Flurry logError:@"Uncaught" message:@"Crash!" exception:exception]; 
    NSLog(@"Exception: %@", exception);

    NSLog(@"Stack trace: %@", stack); 
    NSString *stackTrace = [stack description];
