我封裝的使用AFNetworking上傳多圖的一個方法。帶進度條回調(diào)，希望對你用幫助，我app中親測可用，不知道你的服務器是如何接收數(shù)據(jù)的：
聲明：
/**
*??上傳帶圖片的內(nèi)容，允許多張圖片上傳（URL）POST
*
*??@param url???????????????? 網(wǎng)絡請求地址
*??@param images??????????????要上傳的圖片數(shù)組（注意數(shù)組內(nèi)容需是圖片）
*??@param parameter?????????? 圖片數(shù)組對應的參數(shù)
*??@param parameters??????????其他參數(shù)字典
*??@param ratio?????????????? 圖片的壓縮比例（0.0~1.0之間）
*??@param succeedBlock????????成功的回調(diào)
*??@param failedBlock???????? 失敗的回調(diào)
*??@param uploadProgressBlock 上傳進度的回調(diào)
