Upload images on iOS

The following describes how to upload images:

-(Void) LoadImage :( nsstring *) aurl
{
Nsdata * imagedata;
Nsmutabledata * postbody;
Nsstring * stringboundary, * contenttype;
Nsurl * url = [nsurl urlwithstring: aurl]; // convert the string to nsurl format

Nsarray * paths = nssearchpathfordirectoriesindomains (nsdocumentdirectory, nsuserdomainmask, yes );
Nsstring * documentsdirectory = [paths objectatindex: 0];
Nsstring * Path = [documentsdirectory stringbyappendingpathcomponent: @ "1.jpg"];

Imagedata = [[nsdata alloc] initwithcontentsoffile: path];

Asiformdatarequest * arequest = [[asiformdatarequest alloc] initwithurl: url];

Stringboundary = [nsstring stringwithstring: @ "0 xkhtmlboundary"];

Contenttype = [nsstring stringwithformat: @ "multipart/form-data; boundary =%@", stringboundary];

[Arequest addrequestheader: @ "Content-Type" value: contenttype];

Postbody = [[nsmutabledata alloc] init];

[Postbody appenddata: [[nsstring stringwithformat: @ "\ r \ n -- % @ \ r \ n", stringboundary] datausingencoding: nsutf8stringencoding];
