刚开始接触APP端程序处理。
现在问题就卡在TP端接收IOS传过来的图片，请问TP端处理上传的图片数据该是怎样流程？要注意些什么问题，如数据格式应该是什么？
请问下面的处理方式正确吗？
ios文件如下：

Thinkphp处理文件：
$ugc_topic = M('ugc_topic');
$ugc_image_type = M('ugc_image_type');
$tmp_str = '';
$upload = $_POST;
foreach($upload as $value => $key) {
$tmp_str.= '-----'.$key.'=>'.$value."\n\r";
}
// ----------------调试程序----------------------
$filename = dirname(__FILE__).'/file.txt';
$now_time = date('Y-m-d H:i:s' , time());
$word2 = "{$now_time}\n\r{$tmp_str}\n\r\n\r";
$fh = fopen($filename, "a+");
echo fwrite($fh, $word2);
fclose($fh);
$user_id = I('post.user_id','','htmlspecialchars'); // 当前登陆成功的用户id
$title = I('post.title','','htmlspecialchars'); // 当前发布话题的标题
$content = I('post.content','','htmlspecialchars'); // 当前发布话题的内容
$remind_who = I('post.remind_who','','htmlspecialchars'); // 提醒谁看的用户id
$image_name = I('post.image_name','','htmlspecialchars'); // 当前发布话题的图片
header("Content-Type: application/octet-stream");
$byte = $_POST['image_name'];
$byte = str_replace(' ','',$byte); //处理数据
$byte = str_ireplace("<",'',$byte);
$byte = str_ireplace(">",'',$byte);
$byte = pack("H*",$byte); //16进制转换成二进制
$filename2 = dirname(__FILE__).'/file.txt';
$word22 = "\n\r\n\r{$byte}\n\r\n\r";
$fhf = fopen($filename2, "a+");
echo fwrite($fhf, $word22);
fclose($fhf);
header('Content-type: text/json; charset=UTF-8');
$base64 = $_POST["file"]; // 得到参数
$img = base64_decode($base64); // 将格式为base64的字符串解码
$path = "md5(uniqid(rand()))".".jpg"; // 产生随机唯一的名字作为文件名
file_put_contents($path, $img); // 将图片保存到相应位置
header('Content-type: text/json; charset=UTF-8' );请赐教~多谢！
