iOS 基于AFNetworking的多张图片上传

NSArray * _image =@[];

///////////

//////将多张图片一次性上传到后台，后台将数据一对应Array格式取出

for (int i=0; i<_imageArr.count; i++) {

UIImage * image =_imageArr[i];

NSData *data = UIImageJPEGRepresentation(image, 0.9);

NSString *name =[NSString stringWithFormat:@"image_ios_%d.png",i];

NSString *formKey =[NSString stringWithFormat:@"image%d",i];

NSString *type = @"image/jpeg";

[formData appendPartWithFileData:data name:formKey fileName:name mimeType:type];

}
