UIImage *image=[info objectForKey:UIImagePickerControllerOriginalImage];
NSData *dataItems=UIImageJPEGRepresentation(image, 0.1);
NSString *convertimage=[[NSString alloc]initWithData:dataItems encoding:NSUTF8StringEncoding];
NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration: defaultConfigObject delegate: nil delegateQueue: [NSOperationQueue mainQueue]];
NSURL * url = [NSURL URLWithString:#"http:my url"];
NSMutableURLRequest * urlRequest = [NSMutableURLRequest requestWithURL:url];
//
// NSString *boundary = #"---------------------------14737809831466499882746641449";
// NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
// [urlRequest addValue:contentType forHTTPHeaderField: #"Content-Type"];
//
// NSMutableData *body = [NSMutableData data];
//
// [body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
//
// [body appendData:[[NSString stringWithString:[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"user_file\"; filename=\"%d\"\r\n", 1]] dataUsingEncoding:NSUTF8StringEncoding]];
//
// [body appendData:[#"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
//
// [body appendData:[NSData dataWithData:dataItems]];
//
// [body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
//
// [urlRequest setHTTPBody:body];
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
// getting an NSString
NSString *UserID = [prefs stringForKey:#"sfffehr_id"];
NSLog(#"%#",UserID);
NSString *params=[[NSString alloc]initWithFormat:#"sfffehr_id =%# & user_file=%#",UserID,convertimage];
NSLog(#"%#",params);
[urlRequest setHTTPMethod:#"POST"];
[urlRequest setHTTPBody:[params dataUsingEncoding:NSUTF8StringEncoding]];
[urlRequest setHTTPBody:[params dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES]];
NSURLSessionDataTask * dataTask =[defaultSession dataTaskWithRequest:urlRequest
completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSLog(#"Response:%# %#\n", response, error);
if(error == nil)
{
NSString * text = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];
NSLog(#"Data = %#",text);
}
}];
[dataTask resume];
my response is
fdg[1816:949041] user_file=(null)
fdg[1816:949041] Logo Changed
fdg[1816:949041] Response:<NSHTTPURLResponse: 0x136a2bcb0> { URL: url } { status code: 200, headers {
fdg[1816:949041] Data = {"response":"yes","success":"User profile picture updated successfully"}
When i check in my server i did't find my saved image.

I have made some corrections on your code. Try this now:
UIImage *image=[info objectForKey:UIImagePickerControllerOriginalImage];
NSData *dataItems=UIImageJPEGRepresentation(image, 0.1);
NSString *convertimage = [[NSString alloc] initWithData:dataItems encoding:NSUTF8StringEncoding];
NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration: defaultConfigObject delegate: nil delegateQueue: [NSOperationQueue mainQueue]];
NSURL * url = [NSURL URLWithString:#"http://469.5350.747.4557/~lcall/index.php/webservices/update_profile_picture"];
NSMutableURLRequest * urlRequest = [NSMutableURLRequest requestWithURL:url];
[urlRequest setHTTPMethod:#"POST"];
NSString *boundary = #"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[urlRequest addValue:contentType forHTTPHeaderField: #"Content-Type"];
NSMutableData *body = [NSMutableData data];
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
NSString *UserID = [prefs stringForKey:#"user_id"];
//Populate a dictionary with all the regular values you would like to send.
NSMutableDictionary *parameters = [[NSMutableDictionary alloc] init];
[parameters setValue:UserID forKey:#"user_id"];
[parameters setValue:convertimage forKey:#"user_file"];
// add params (all params are strings)
for (NSString *param in parameters) {
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"%#\"\r\n\r\n", param] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"%#\r\n", [parameters objectForKey:param]] dataUsingEncoding:NSUTF8StringEncoding]];
}
[body appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"user_file\"; filename=\"image.png\"\r\n"]] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:dataItems]];
[body appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[urlRequest setHTTPBody:body];
// getting an NSString
NSURLSessionDataTask * dataTask = [defaultSession dataTaskWithRequest:urlRequest completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSLog(#"Response:%# %#\n", response, error);
if(error == nil){
NSString * text = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];
NSLog(#"Data = %#",text);
}
}];
[dataTask resume];
Note:
I have make necessary corrections in your code & Its Error free. But i have not tested it. Please check.
I hope it will work for you.
