var xhr = new XMLHttpRequest();

success = true;
$("#updateHoardingModal").modal("hide");

}
Ios code:
NSString * jsosSt=[self strOfthedata];
UIImage *imageOne = [UIImage imageNamed:#"edit.png"];
NSData *imageData1 = UIImageJPEGRepresentation(imageOne,0.6f);
NSString *fileName1 = [NSString stringWithFormat:#"%ld%c%c.jpeg", (long)[[NSDate date] timeIntervalSince1970], arc4random_uniform(26) + 'a', arc4random_uniform(26) + 'a'];
NSDictionary *params=#{#"token":appdeligate.userInf.tokenId,#"hoardingjson":[self strOfthedata]};
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:#"POST" URLString:#"URL/CreateHoarding" parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileURL:[NSURL fileURLWithPath:savedImagePath] name:#"file" fileName:#"filename.jpg" mimeType:#"image/jpeg" error:nil];
} error:nil];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSMutableString *strParams = [[NSMutableString alloc]init];
for (NSString *key in [params allKeys]) {
[strParams appendFormat:#"%#=%#", key, params[key]];
[strParams appendString:#"&"];
}
[strParams deleteCharactersInRange:NSMakeRange([strParams length]-1, 1)];
[request setHTTPBody:[strParams dataUsingEncoding:NSUTF8StringEncoding]];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"content-type"];
NSURLSessionUploadTask *uploadTask;
uploadTask = [manager
uploadTaskWithStreamedRequest:request
progress:^(NSProgress * _Nonnull uploadProgress) {
// This is not called back on the main queue.
// You are responsible for dispatching to the main queue for UI updates
dispatch_async(dispatch_get_main_queue(), ^{
//Update the progress view
[progressView setProgress:uploadProgress.fractionCompleted];
NSLog(#"%f",uploadProgress.fractionCompleted);
});
}
completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) {
if (error) {
NSLog(#"Error: %#", error);
} else {
NSLog(#"%# %#", response, responseObject);
}
}];
[uploadTask resume];

Answer 1

Here it is using AFNetworking
AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:[NSURL URLWithString:stringURL]];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
[manager POST:stringURL parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
{
//do not put image inside parameters dictionary as I did, but append it!
[formData appendPartWithFileData:nsdataFromBase64String name:#"" fileName:#"" mimeType:#"image/jpeg"];
}
success:^(NSURLSessionDataTask *task, id responseObject)
{
//here is place for code executed in success case
}
failure:^(NSURLSessionDataTask *task, NSError *error)
{
//here is place for code executed in error case
}];
stringURL is the URL where you want to upload/send the image.
NSData *nsdataFromBase64String = [[NSData alloc] initWithBase64EncodedString:pBytes options:0];
Where nsdataFromBase64String is image conversion to base64 string and decode the same on server
Check the mime type if you want png.
