iOS 使用AFNetworking实现多张图片上传

#import"AFNetworking.h"

/**

 * 上传带图片的内容，允许多张图片上传（URL）POST

 *

 *  @param url          传url

 *  @param images       要上传的图片数组（注意数组内容需是图片）

 *  @param parameter    图片数组对应的参数 可以为nil

 *  @param parameters   其他参数字典 可以为nil

 *  @param ratio        图片的压缩比例（0.0~1.0之间）

 *  @param succeedBlock 成功的回调

 *  @param failedBlock  失败的回调
