I was trying to load data for the table using values from server.I am using NSURLSession datatask with completion handler. Whenever it reaches the nsurlsession, it shows error.This is the code which i used for getting data.
- (void)geturl:(NSString *)urlvalue datavalues:(NSString *)string fetchGreetingcompletion:(void (^)(NSDictionary *dictionary, NSError *error))completion{
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"%#%#?%#",common.getUrlPort,urlvalue,common.getappversion]];
NSLog(#"url=%#",url);
NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration: defaultConfigObject delegate: nil delegateQueue: [NSOperationQueue mainQueue]];
NSMutableURLRequest * urlRequest = [NSMutableURLRequest requestWithURL:url];
[urlRequest addValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
[urlRequest addValue:common.getauthtoken forHTTPHeaderField:#"Authorization"];
//Create POST Params and add it to HTTPBody
[urlRequest setHTTPMethod:#"GET"];
NSURLSessionDataTask * dataTask =[defaultSession dataTaskWithRequest:urlRequest
completionHandler:^(NSData *data, NSURLResponse *response, NSError *connectionError) {
NSLog(#"Response:%# %#\n", response, connectionError);
if (data.length > 0 && connectionError == nil)
{
NSDictionary *greeting = [NSJSONSerialization JSONObjectWithData:data options:0 error:NULL];
NSString *code = [NSString stringWithFormat:#"%#",[greeting valueForKey:#"code"]];
if([code isEqualToString:#"-1"]){
[self loaderrorview:greeting];
}
else{
if (completion)
completion(greeting, connectionError);
}
}
else if(data == nil){
NSDictionary *errorDict=[[NSDictionary alloc]initWithObjectsAndKeys:#"Server Connection Failed",#"error", nil];
if (completion)
completion(errorDict,connectionError);
}
else
{
NSDictionary *greeting = [NSJSONSerialization JSONObjectWithData:data options:0 error:NULL];
if (completion)
completion(greeting, connectionError);
}
}];
[dataTask resume];
}
The code which i used for getting data from server:
-(void)getdataexplore{
if (!common.checkIfInternetIsAvailable) {
[self.view makeToast:Nointernetconnection];
} else {
NSLog(#"There is internet connection");
[SVProgressHUD setDefaultMaskType:SVProgressHUDMaskTypeBlack];

[apiservice geturl:loadexploredata datavalues:nil fetchGreetingcompletion:^(NSDictionary *dictionary, NSError *error) {
//NSLog(#"Test %# Error %#",dictionary,error);
if(error == nil){
authDictionary = dictionary;
[self loaddata];
}
else{
[SVProgressHUD dismiss];
[view_business makeToast:#"Request timed out" duration:2.0 position:CSToastPositionCenter];
}
}];
}
}
The code which i used for storing server data to array:
-(void)loaddata

[SVProgressHUD showWithStatus:#"Loading..."];
//[SVProgressHUD dismiss];
NSString *msg = [authDictionary valueForKey:#"msg"];

I am getting error like "Unable to run main thread". Any solution for this.
I need to integrate SMS Verification using Twilio url.
I have ACCOUNT_SID,AUTH_TOKEN and url but not able to parse using Objective C.
CODE:
NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:config delegate:self delegateQueue:[NSOperationQueue mainQueue]];
NSString *post = [NSString stringWithFormat:#"From='number'To=%#&Body=message %d to verify your mobile number.",txt_otp.text,[[self sms_verification_code]intValue]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"https://api.twilio.com/2010-04-01/Accounts/(SID)/SMS/Messages"]cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSString *authStr = [NSString stringWithFormat:#"SID:TOKEN"];
NSData *authData = [authStr dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:[post dataUsingEncoding:NSUTF8StringEncoding]];
NSString *authValue = [NSString stringWithFormat:#"Basic %#", [authData base64EncodedStringWithOptions:0]];
[request setValue:authValue forHTTPHeaderField:#"Authorization"];
[[session dataTaskWithRequest:request
completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
if (!error) {
NSDictionary *responseDictionary = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSLog(#"SMS verification%#",responseDictionary);
}

NSString *kFromNumber = #"";
NSString *kToNumber =#"";
NSString *kMessage = [NSString stringWithFormat:#"message %d",[[self sms_verification_code] intValue]];

first of all please, click on this link then...
How I'm getting this output like name ,std & assign to textbox I'm already done this in xcode 5 but NSURLCOnnection not used in xcode 7.2 so Using NSURLSESSION How Can I bind to textbox??
NSError *error = nil;
NSMutableDictionary *dic2 = [[NSMutableDictionary alloc] init];
[dic2 setObject:#"324" forKey:#"grno"];
NSMutableDictionary *dic = [[NSMutableDictionary alloc] init];
[dic setObject:#"RestAPI" forKey:#"interface"];
[dic setObject:#"StudentLogin" forKey:#"method"];
[dic setObject:dic2 forKey:#"parameters"];
NSData *postData = [NSJSONSerialization dataWithJSONObject:dic options:NSJSONWritingPrettyPrinted error:&error];
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://ios.skyzon.in/STudent/STudentDetail"]];
[req setHTTPMethod:#"POST"];
[req setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[req setHTTPBody:postData];
NSURLSessionDataTask * dataTask =[defaultSession dataTaskWithRequest:req
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);
NSMutableDictionary *responseDic = [[NSMutableDictionary alloc]init];
responseDic = [NSJSONSerialization JSONObjectWithData:postData options:NSJSONReadingAllowFragments error:&error];
NSLog(#"%#",responseDic);
self.txt.text = [responseDic objectForKey:#"Name"];
NSLog(#"%#",[responseDic objectForKey:#"Name"]);
}
}];
[dataTask resume];
You can you NSURLSESSION like below.
NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionDataTask *dataTask = [session dataTaskWithURL:[NSURL URLWithString:#"http://ios.skyzon.in/STudent/STudentDetail"] completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
NSLog(#"%#", json);
self.txt.text = [responseDic objectForKey:#"Name"];
}];
May be it will help you.
I'm using this function to send a request to a server and receive JSON response in an NSDictionary.
- (void)performRequest:(NSString *)aRequest
{
NSString *string=[NSString stringWithFormat:#"%#%#",baseURL,aRequest];
NSURL *url = [NSURL URLWithString: string];
NSLog(#"string%#",string);
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[NSURLConnection sendAsynchronousRequest:request
queue:[NSOperationQueue mainQueue]
completionHandler:^(NSURLResponse *response,
NSData *data, NSError *connectionError)
{
if (data.length > 0 && connectionError == nil)
{
NSDictionary * greeting = [NSJSONSerialization JSONObjectWithData:data
options:0
error:NULL];
NSLog(#"%#",greeting2);
}
}];
}
What I want is to modify it so that it remains a function sending service URL and a separate one where the JSON response comes at a NSDictionary so you can reuse them in other classes.
I used the networking introduced by iOS 7: NSURLSession. This is the networking code I use in a project. But I would suggest you to use AFNetworking instead. That will save you more time on it. It depends on what you want in your application.
+ (void)requestOperationWithMethod:(NSString *)method
withUrl:(NSString *)url
header:(NSDictionary *)header
params:(NSDictionary *)params
completion:(FHCompletionResultBlock)completion {
FHNetworking *network = [FHNetworking shareNetworking];
NSData *bodyData;
NSError *jsonError = nil;
NSData *data = [NSJSONSerialization dataWithJSONObject:params options:kNilOptions error:&jsonError];
if (!jsonError) {
bodyData = data;
}
// prepare http request header and body data fields
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url]];
for (NSString *key in header.allKeys) {
[request setValue:header[key] forHTTPHeaderField:key];
}
[request setHTTPMethod:method];
[request setHTTPBody:bodyData];
[request setTimeoutInterval:30.0f];
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES];
[[network.session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error){
NSError *jsonError = nil;
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&jsonError];
if (jsonError)
completion(nil, jsonError);
else {
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
if (httpResponse.statusCode >= 400) {
if (json[#"code"] && json[#"error"]) {
NSError *error = [NSError errorWithDomain:#"Error" code:[json[#"code"] integerValue] userInfo:#{NSLocalizedDescriptionKey: NSLocalizedString(json[#"error"], nil)}];
completion(nil, error);
}
else {
NSError *error = [NSError errorWithDomain:#"Error" code:-1 userInfo:#{NSLocalizedDescriptionKey: NSLocalizedString(#"Unknown error", nil)}];
completion(nil, error);
}
}
else {
completion(json, nil);
}
}
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];
}] resume];
}
You can change your method to take a completionHandler parameter, itself:
- (void)performRequest:(NSString *)aRequest completionHandler:(void(^)(NSDictionary *responseObject, NSError *error))completionHandler
{
NSString *string=[NSString stringWithFormat:#"%#%#",baseURL,aRequest];
NSURL *url = [NSURL URLWithString: string];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[NSURLConnection sendAsynchronousRequest:request
queue:[NSOperationQueue mainQueue]
completionHandler:^(NSURLResponse *response,
NSData *data, NSError *connectionError) {
if (data.length > 0 && connectionError == nil) {
NSError *parseError;
NSDictionary *responseObject = [NSJSONSerialization JSONObjectWithData:data
options:0
error:&parseError];
completionHandler(responseObject, parseError);
} else {
completionHandler(nil, error);
}
}];
}
Now you can call it and supply whatever you want in the completion handler:
[self performRequest:requestString completionHandler:^(NSDictionary *responseObject, NSError *error) {
if (responseObject) {
// everything is good; use your NSDictionary here
} else {
// handle error here
}
}];
Most of the information here refers to the abandoned ASIHTTPREQUEST project so forgive me for asking again.
Effectively, I need to swipe a magnetic strip and send the track 2 data to a webservice that returns "enrolled" or "notenrolled" (depending on the status of the card...)
So my data comes in simply as
NSData *data = [notification object];
And then I need to pass this to a url to the order of
http://example.com/CardSwipe.cfc?method=isenrolled&track2=data
And then just receive a response string...
I've searched a ton and there seems to be some conflicting answers as to whether this should be accomplished simply with AFNetworking, RESTkit, or with the native NSURL/NSMutableURLRequest protocols.
The options for performing HTTP requests in Objective-C can be a little intimidating. One solution that has worked well for me is to use NSMutableURLRequest. An example (using ARC, so YMMV) is:
- (NSString *) getDataFrom:(NSString *)url{
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setHTTPMethod:#"GET"];
[request setURL:[NSURL URLWithString:url]];
NSError *error = nil;
NSHTTPURLResponse *responseCode = nil;
NSData *oResponseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&responseCode error:&error];
if([responseCode statusCode] != 200){
NSLog(#"Error getting %#, HTTP status code %i", url, [responseCode statusCode]);
return nil;
}
return [[NSString alloc] initWithData:oResponseData encoding:NSUTF8StringEncoding];
}
Update:
Your question's title, and tagging say POST, but your example URL would indicate a GET request. In the case of a GET request, the above example is sufficient. For a POST, you'd change it up as follows:
- (NSString *) getDataFrom:(NSString *)url withBody:(NSData *)body{
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:body];
[request setValue:[NSString stringWithFormat:#"%d", [body length]] forHTTPHeaderField:#"Content-Length"];
[request setURL:[NSURL URLWithString:url]];
/* the same as above from here out */
}
Update for iOS 9:
So, [NSURLConnection sendSynchronousRequest] is deprecated starting from iOS 9. Here's how to do a GET request using NSURLSession starting from iOS 9
GET Request
// making a GET request to /init
NSString *targetUrl = [NSString stringWithFormat:#"%#/init", baseUrl];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setHTTPMethod:#"GET"];
[request setURL:[NSURL URLWithString:targetUrl]];
[[[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:
^(NSData * _Nullable data,
NSURLResponse * _Nullable response,
NSError * _Nullable error) {
NSString *myString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"Data received: %#", myString);
}] resume];
POST Request
// making a POST request to /init
NSString *targetUrl = [NSString stringWithFormat:#"%#/init", baseUrl];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
//Make an NSDictionary that would be converted to an NSData object sent over as JSON with the request body
NSDictionary *tmp = [[NSDictionary alloc] initWithObjectsAndKeys:
#"basic_attribution", #"scenario_type",
nil];
NSError *error;
NSData *postData = [NSJSONSerialization dataWithJSONObject:tmp options:0 error:&error];
[request setHTTPBody:postData];
[request setHTTPMethod:#"POST"];
[request setURL:[NSURL URLWithString:targetUrl]];
[[[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:
^(NSData * _Nullable data,
NSURLResponse * _Nullable response,
NSError * _Nullable error) {
NSString *responseStr = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"Data received: %#", responseStr);
}] resume];
Tested 100% working
Only for Objective C
-(void)fetchData
{
NSURLSessionConfiguration *defaultSessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration:defaultSessionConfiguration];
// Setup the request with URL
NSURL *url = [NSURL URLWithString:#"https://test.orgorg.net/ios/getStory.php?"];
NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url];
// Convert POST string parameters to data using UTF8 Encoding
NSString *postParams = #"";
NSData *postData = [postParams dataUsingEncoding:NSUTF8StringEncoding];
// Convert POST string parameters to data using UTF8 Encoding
[urlRequest setHTTPMethod:#"POST"];
[urlRequest setHTTPBody:postData];
// Create dataTask
NSURLSessionDataTask *dataTask = [defaultSession dataTaskWithRequest:urlRequest completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSDictionary *results = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
//JSON Parsing....
NSString *message = results[#"Message"];
BOOL status = results[#"Status"];
if (status){
// Here you go for data....
}else{
UIAlertController *alert = [UIAlertController alertControllerWithTitle:#"App"
message:message
preferredStyle:UIAlertControllerStyleAlert]; // 1
UIAlertAction *firstAction = [UIAlertAction actionWithTitle:#"Ok"
style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {
NSLog(#"You pressed button one");
}]; // 2
[alert addAction:firstAction]; // 4
[self presentViewController:alert animated:YES completion:nil];
}
}];
// Fire the request
[dataTask resume];
}
For Objective c :
-(void)loadData:(NSString*)url{
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:#"https://jsonplaceholder.typicode.com/posts"]];
[request setHTTPMethod:#"GET"];
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
[[session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
NSMutableArray *jsonArray = (NSMutableArray *)[NSJSONSerialization JSONObjectWithData:data options:NSASCIIStringEncoding error:&error];
if([self.delegate respondsToSelector:#selector(loadingData:)]){
[self.delegate loadingData:jsonArray];
}
}] resume];
}
Swift 5.5:
// MARK: - Posts
func getPosts(endPath : String, completion: #escaping ([Post]) -> ()) {
let urlPath = Constants.Network.BASE_URL + endPath
guard let url = URL(string: urlPath) else {
print("Invalid URL")
return
}
var request = URLRequest(url: url)
request.httpMethod = Constants.Network.HTTPS_METHOD
URLSession.shared.dataTask(with: request) { data, response, error in
if let data = data {
if let decodedResponse = try? JSONDecoder().decode([Post].self, from: data) {
DispatchQueue.main.async {
completion(decodedResponse)
}
return
}
}
print("Fetch failed: \(error?.localizedDescription ?? "Unknown error")")
}.resume()
