NSLog(#"Sending request.");
// Common constants
NSString *kTwilioSID = delegate.sessionId;
NSString *kTwilioSecret = delegate.twilioToken;

NSString *kToNumber = #"[phone]";
NSString *kMessage = #"Hi there......";
// Build request
NSString *urlString = [NSString stringWithFormat:#"https://%#:%##api.twilio.com/2010-04-01/Accounts/%#/SMS/Messages", kTwilioSID, kTwilioSecret, kTwilioSID];
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:url];
[request setHTTPMethod:#"POST"];
// Set up the body
NSString *bodyString = [NSString stringWithFormat:#"From=%#&To=%#&Body=%#", kFromNumber, kToNumber, kMessage];
NSData *data = [bodyString dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPBody:data];
NSError *error;
NSURLResponse *response;
NSData *receivedData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
// Handle the received data
if (error) {
NSLog(#"Error: %#", error);

Please help to do this issue, or share with me any helping meterial. Thanks in Advance.

Answer 1

According to this answer, error 1012 means that a request for authentication was canceled by the user.
It's just a hunch, but you may want to try using HTTP Basic Auth by adding an Authorization header like this: Objective-c HTTP Basic authentication instead of including the credentials in the URL string, which counts on the Objective C library to turn those into a header correctly.

Answer 2

Make sure that the HttpPost param is URL-encoded, so you should change
NSString *kToNumber = #"[phone]";
to
NSString *kToNumber = #"%2B14126620408";

Answer 3

I've written this blog post to help you get this done quickly using Xcode 8 and Swift 3.
https://www.twilio.com/blog/2016/11/how-to-send-an-sms-from-ios-in-swift.html
Using a server-side language of your choosing and Alamofire for HTTP requests, the request boils down to this:
#IBAction func sendData(sender: AnyObject) {
let headers = [
"Content-Type": "application/x-www-form-urlencoded"
]
let parameters: Parameters = [
"To": phoneNumberField.text ?? "",
"Body": messageField.text ?? ""
]
Alamofire.request("YOUR_NGROK_URL/sms", method: .post, parameters: parameters, headers: headers).response { response in
print(response)
}
}

Answer 4

#IBAction func sendData(sender: AnyObject) {
let headers = [
"Content-Type": "application/x-www-form-urlencoded"
]
let parameters: Parameters = [
"To": "enter your number",
"Body": "enter your text"
]
Alamofire.request("YOUR_NGROK_URL/sms", method: .post, parameters: parameters, headers: headers).response { response in
print(response)
}
}
you must be installed
TIP: pod 'Alamofire', '~> 5.2'
