• AFN解耦

  • 自定義單利類基礎(chǔ)Manager
  • 優(yōu)點(diǎn): 替換框架只需要求改單利類即可

• 序列化

  • AFN默認(rèn)將服務(wù)器返回的數(shù)據(jù)當(dāng)做JSON處理, 會自動解析
    • manager.responseSerializer = [AFJSONRequestSerializer serializer];
  • 告訴AFN，以xml形式解析服務(wù)器返回的數(shù)據(jù)
    • manager.responseSerializer = [AFXMLParserResponseSerializer serializer];
  • 告訴AFN, 不處理服務(wù)器返回的數(shù)據(jù), 原樣返回
    • manager.responseSerializer = [AFHTTPResponseSerializer serializer];

  CocoaPods安裝失敗

  • CocoaPods安裝東西的時(shí)候它要找到Xcode的Developer文件夾, 如果找不到會報(bào)如下錯(cuò)誤

  • 解決方案

    • JX替換為你自己的用戶名

    • sudo xcode-select --switch /Users/JX/applications/Xcode.app/Contents/Developer
