Issue in uploading images on Facebook using batch JSON process in iPhone? - iphone

Question

Now my i trying to use batch method for sending multiple methods, so i used following code for trying to send two images on Facebook using FBGraph,
NSString *req01 = #"{ \"method\": \"POST\", \"relative_url\": \"me/photos\", \"body\": \"message=MyMessageOnPhotoone\", \"attached_files\": \"myimagedata\"}";
NSString *req02 = #"{ \"method\": \"POST\", \"relative_url\": \"me/photos\", \"body\": \"message=MyMessageOnPhototwo\", \"attached_files\": \"myimagedata\"}";
NSString *allRequests = [NSString stringWithFormat:#"[ %#, %# ]", req01, req02];
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObject:allRequests forKey:#"batch"];
[facebook requestWithGraphPath:#"me" andParams:params andHttpMethod:#"POST" andDelegate:self];
And batch method is,
curl
–F 'access_token=…' \
-F 'batch=[{"method":"POST", \
"relative_url":"me/photos", \
"body":"message=My cat photo" \
"attached_files":"file1" \
},
{"method":"POST", \
"relative_url":"me/photos", \
"body":"message=My dog photo" \
"attached_files":"file2" \
},
]’
-F 'file1=#cat.gif' \
-F 'file2=#dog.jpg' \
https://graph.facebook.com
I got following error,
(
{
my binary image encoded data
code = 400;
headers = (
{
name = "WWW-Authenticate";
my binary image encoded data
},
{
name = "HTTP/1.1";
value = "400 Bad Request";
},
{
name = "Cache-Control";
value = "no-store";
},
{
name = "Content-Type";
value = "text/javascript; charset=UTF-8";
}
);
},
{
myimage binary encoded data
code = 400;
headers = (
{
name = "WWW-Authenticate";
myimageBinary encoded data
},
{
name = "HTTP/1.1";
value = "400 Bad Request";
},
{
name = "Cache-Control";
value = "no-store";
},
{
name = "Content-Type";
value = "text/javascript; charset=UTF-8";
}
);
}
)
I can't able to rectify the problem is in URL request in my code.
