                                       cachePolicy:NSURLRequestUseProtocolCachePolicy 
                                       timeoutInterval:60]; 

        [request setHTTPMethod:@"POST"]; 

        NSString *boundary = @"----WebKitFormBoundarycC4YiaUFwM44F6rT";

        NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];

        [request addValue:contentType forHTTPHeaderField: @"Content-Type"];

        NSMutableData *body = [NSMutableData data];

        [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

        [body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name="attachment[file]";
        filename="picture.png"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];

        [body appendData:[[NSString stringWithString:@"Content-Type: image/png\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];

        [body appendData:[NSData dataWithData:imageData]];

        [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

        [request setHTTPBody:body];

        NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request 
                                                               delegate:self 
                                                               startImmediately:NO]; 

        [connection scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:DataDownloaderRunMode]; 

        [connection start];
}

and connecting this to post button..

that first link does exactly what you want, if you are having specific problems you should post your code and any errors — wattson12, Dec 27 '12 at 10:04
@wattson12 when i use code of first link it shows error in this line...[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name="attachment[file]"; filename="picture.png"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; — Kundan, Dec 27 '12 at 10:05
@wattson12 the error is expected ' '.but i don't know where.... — Kundan, Dec 27 '12 at 10:07
@user1865424 you use the link which i give you dude?? follow that tutorials?? — Paras Joshi, Dec 27 '12 at 10:11

@NSIllusion my code shows error..so,no response getting...but i am showing my code..i am editing above... — Kundan, Dec 27 '12 at 10:16
@user1865424: Have you setup the delegate methods for `NSURLConnection` ? Use them to fetch response from the webserver to which you are uploading the image. And can you edit your question with those error messages ? — sunhsiv, Dec 27 '12 at 11:58

UPDATE:

[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"picture\"; filename=\"picture.png\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];

Here your database field name for store the image is picture then write the field name in name parameter...

use this code...

// add image data
NSData *imageData = UIImageJPEGRepresentation(imageToPost, 1.0);
if (imageData) {
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"image.jpg\"\r\n", FileParamConstant] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:@"Content-Type: image/jpeg\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:imageData];
    [body appendData:[[NSString stringWithFormat:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
}

Follow this answer Link

Or you can use ASIHTTP classes for this

ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:@"http://URL/Service.asmx/RegisterClient?"]];
            request.delegate=self;

            encodedImage = UIImagePNGRepresentation(imgRef);

            [[NSUserDefaults standardUserDefaults]setObject:UIImagePNGRepresentation(imgRef) forKey:@"userImage"];

            str =[Base64 encode:encodedImage];

           [request setPostValue:email.text forKey:@"Email"];

            [request setPostValue:name.text forKey:@"FName"];
            [request setPostValue:str forKey:@"UserImage"];
            [request setPostValue:dob.text forKey:@"dob"];
            [request setPostValue:phoneNumber.text forKey:@"Phone"];
            [request setPostValue:ggg.text forKey:@"Gender"];
            [request setPostValue:address.text forKey:@"Address"];
            [request setPostValue:interest.text forKey:@"Interest"];

            [request startAsynchronous];
