1.?AFHTTPRequestOperationManager?*manager?=?[AFHTTPRequestOperationManager?manager];
所有的網(wǎng)絡(luò)請求,均有manager發(fā)起
2.需要注意的是,默認(rèn)提交請求的數(shù)據(jù)是二進(jìn)制的,返回格式是JSON
1>如果提交數(shù)據(jù)是JSON的,需要將請求格式設(shè)置為AFJSONRequestSerializer
2>如果返回格式不是JSON的,
3.請求格式
AFHTTPRequestSerializer ?二進(jìn)制格式
AFJSONRequestSerializer????????????JSON
AFPropertyListRequestSerializer????PList(是一種特殊的XML,解析起來相對容易)
4.返回格式
AFHTTPResponseSerializer二進(jìn)制格式
AFJSONResponseSerializer???????????JSON
AFXMLParserResponseSerializer??????XML,只能返回XMLParser,還需要自己通過代理方法解析
AFXMLDocumentResponseSerializer?(Mac?OS?X)
AFPropertyListResponseSerializer???PList
AFImageResponseSerializer??????????Image
AFCompoundResponseSerializer組合
