AFNetworking form data uploading issue - ios

Question

I want to POST form data using AFNetworking. I am using this piece of code to achieve this:
// Create service request url
NSString *urlString = [NSString stringWithFormat:#"%#%#", kBaseURL, webServiceAPIName];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager.requestSerializer setValue:#"myUser" forHTTPHeaderField:#"X-User-Agent"];
[manager.requestSerializer setValue:#"multipart/form-data" forHTTPHeaderField:#"Content-Type"];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
// Set calling keys
NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
[dict setObject:#"5341" forKey:#"Id"];
[dict setObject:#"f1" forKey:#"refDataId"];
[dict setObject:#"f1" forKey:#"customRefDataId"];
[dict setObject:#"587" forKey:#"cost"];
[manager POST:urlString parameters:dict constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:UIImagePNGRepresentation(files[0]) name:#"ImageName" fileName:#"file1" mimeType:#"image/png"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"upload successful");
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error image upload");
}];
After execution of this block after waiting some time it goes in Failure Section. Logging : "Error image upload". without giving any error.
I tried my API in POSTMAN API CLIENT and there it is working fine.I am able to send data and get response back.
And after running this block i am not able to run any other API call I have to stop my app and run again to run any other API call.
What is the issue with this code why I am not able to upload any form data and Why it block my any other API calls

Try below code:
-(void) uploadImage {
NSString *imagePath = [[NSUserDefaults standardUserDefaults] objectForKey:#"userimage"];
NSString * urlString = [stagingURL stringByReplacingOccurrencesOfString:#"user/" withString:#""];
NSString * uploadURL = #"Your URL where image to be uploaded";
NSLog(#"uploadImageURL: %#", uploadURL);
NSData *imageData = UIImageJPEGRepresentation([UIImage imageWithData:[NSData dataWithContentsOfFile:imagePath]], 0.5);
NSString *queryStringss = [NSString stringWithFormat:#"%#",uploadURL];
queryStringss = [queryStringss stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer=[AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"text/html"];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:#"text/plain"];
[manager POST:queryStringss parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:imageData name:#"file" fileName:#"file" mimeType:#"image/jpeg"];
}
success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"Success: %# ***** %#", operation.responseString, responseObject);
[MBProgressHUD hideAllHUDsForView:self.view animated:YES];
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
[MBProgressHUD hideAllHUDsForView:self.view animated:YES];
NSLog(#"Error: %# ***** %#", operation.responseString, error);
}];}
