AFNetworking AFMultipartFormData how to set key - iphone

Question

I want to upload (POST) image to server with setkey "FileData" like before (wrote with ASIHTTPRequest and it works)
[self.request setData:imageData withFileName:dateFormatted andContentType:#"image/jpeg" forKey:#"Filedata"];
with AFNetworking I set like below:
NSMutableURLRequest *afRequest = [httpClient multipartFormRequestWithMethod:#"POST" path:#"" parameters:paramsDic constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
[formData appendPartWithFileData:imageData name:#"Filedata" fileName:dateFormatted mimeType:#"image/jpeg"];
}];
seems name not actually works...
How should I set the key? #mattt
Thanks

Answer 1

I figure it out, the problem is I add this line
[afRequest setValue:#"application/x-www-form-urlencoded; charset=UTF8" forHTTPHeaderField:#"Content-Type"];
But I still don't know why, I add this line to other http request and it works, but file upload. I checked server, when do file upload with this line, server received many ... hm... come to think how to describe it, mass letters ...like below:
Content-Type: image/jpeg^M ^M
ÿØÿà^#^PJFIF^#^A^A^#^#^A^#^A^#^#ÿá^#XExif^#^#MM^#*^#^#^#^H^#^B^A^R^#^C^#^#^#^A^#^A^#^#<87>i^#^D^#^#^#^A^#^#^#

hi i am uploading audio/image file as below please check it and its working fine using the ASIHTTPRequest.
NSURL *audiourl = [NSURL URLWithString:#"Your Url"];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:audiourl];
NSData *postData = [NSData dataWithContentsOfURL:SoundPath];
//SoundPath is your audio url path of NSDocumentDirectory.
[request addData:postData withFileName:#"mynewfile.png" andContentType:#"image/png" forKey:#"FileData"];
[request setDelegate:self];
[request startasynchronous];
