問題：
Thanks for reading. 謝謝閱讀。
I am new to iOS and I am trying to upload an Image and a text using multi-part form encoding in iOS. 我是iOS的新手，我正在嘗試在iOS中使用multi-part form encoding上傳圖像和文本。
The curl equivalent is something like this: curl -F "param1=value1" -F "[email protected]" " http://some.ip.address:5000/upload " 等效的curl是這樣的： curl -F "param1=value1" -F "[email protected]" " http://some.ip.address:5000/upload "
The curl command above returns the expected correct response in JSON. 上面的curl命令以JSON.返回預期的正確響應JSON.
Problem: I keep getting a HTTP 400 request which means I am doing something wrong while composing the HTTP POST Body. 問題：我不斷收到HTTP 400請求，這意味着在編寫HTTP POST正文時我做錯了什麼。
What I Did: For some reference, I tried Flickr API iOS app "POST size too large!" 我所做的事情：爲了提供一些參考，我嘗試了Flickr API iOS應用“ POST size too too！”。 and Objective C: How to upload image and text using HTTP POST? 和目標C：如何使用HTTP POST上傳圖像和文本？ . 。 But, I keep getting a HTTP 400. 但是，我一直收到HTTP 400。
I tried the ASIHttpRequest but had a different problem there (the callback never got called). 我嘗試了ASIHttpRequest但那裏遇到了另一個問題（從未調用過回調）。 But, I didn't investigate further on that since I've heard the developer has stopped supporting the library: http://allseeing-i.com/[request_release] ; 但是，由於我聽說開發人員已停止支持該庫，因此我對此不作進一步調查： http : //allseeing-i.com/[request_release] ;
Could someone please help me out? 有人可以幫我嗎？
