AFHTTPClient の共有インスタンスを初期化した後、コードの setReachabilityStatusChangeBlock ブロックがあり、次に enqueueBatchOfHTTPRequestOperations があります。問題は、setReachabilityStatusChangeBlock が実行されないことです。私は、enqueueBatchOfHTTPRequestOperations でダウンロードされているファイルを危険にさらす可能性のある貧弱なネットワーク接続を見つけようとしています。
これについての助けは本当に感謝します。
これは私が持っているものの例です...
