Make a phone call programmatically - ios

Question

How can I make a phone call programmatically on iPhone? I tried the following code but nothing happened:
NSString *phoneNumber = mymobileNO.titleLabel.text;
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];

Answer 1

To go back to original app you can use telprompt:// instead of tel:// - The tell prompt will prompt the user first, but when the call is finished it will go back to your app:
NSString *phoneNumber = [#"telprompt://" stringByAppendingString:mymobileNO.titleLabel.text];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];

Answer 2

Probably the mymobileNO.titleLabel.text value doesn't include the scheme //
Your code should look like this:
ObjectiveC
NSString *phoneNumber = [#"tel://" stringByAppendingString:mymobileNO.titleLabel.text];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];
Swift
if let url = URL(string: "tel://\(mymobileNO.titleLabel.text))") {
UIApplication.shared.open(url)
}

Answer 3

Merging the answers of #Cristian Radu and #Craig Mellon, and the comment from #joel.d, you should do:
NSURL *urlOption1 = [NSURL URLWithString:[#"telprompt://" stringByAppendingString:phone]];
NSURL *urlOption2 = [NSURL URLWithString:[#"tel://" stringByAppendingString:phone]];
NSURL *targetURL = nil;
if ([UIApplication.sharedApplication canOpenURL:urlOption1]) {
targetURL = urlOption1;
} else if ([UIApplication.sharedApplication canOpenURL:urlOption2]) {
targetURL = urlOption2;
}
if (targetURL) {
if (#available(iOS 10.0, *)) {
[UIApplication.sharedApplication openURL:targetURL options:#{} completionHandler:nil];
} else {
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
[UIApplication.sharedApplication openURL:targetURL];
#pragma clang diagnostic pop
}
}
This will first try to use the "telprompt://" URL, and if that fails, it will use the "tel://" URL. If both fails, you're trying to place a phone call on an iPad or iPod Touch.
Swift Version :
let phone = mymobileNO.titleLabel.text
let phoneUrl = URL(string: "telprompt://\(phone)"
let phoneFallbackUrl = URL(string: "tel://\(phone)"
if(phoneUrl != nil && UIApplication.shared.canOpenUrl(phoneUrl!)) {
UIApplication.shared.open(phoneUrl!, options:[String:Any]()) { (success) in
if(!success) {
// Show an error message: Failed opening the url
}
}
} else if(phoneFallbackUrl != nil && UIApplication.shared.canOpenUrl(phoneFallbackUrl!)) {
UIApplication.shared.open(phoneFallbackUrl!, options:[String:Any]()) { (success) in
if(!success) {
// Show an error message: Failed opening the url
}
}
} else {
// Show an error message: Your device can not do phone calls.
}

The answers here are perfectly working. I am just converting Craig Mellon answer to Swift. If someone comes looking for swift answer, this will help them.
var phoneNumber: String = "telprompt://".stringByAppendingString(titleLabel.text!) // titleLabel.text has the phone number.
UIApplication.sharedApplication().openURL(NSURL(string:phoneNumber)!)

If you are using Xamarin to develop an iOS application, here is the C# equivalent to make a phone call within your application:
string phoneNumber = "1231231234";
NSUrl url = new NSUrl(string.Format(#"telprompt://{0}", phoneNumber));
UIApplication.SharedApplication.OpenUrl(url);

Answer 6

Swift 3
let phoneNumber: String = "tel://3124235234"
UIApplication.shared.openURL(URL(string: phoneNumber)!)

Answer 7

In Swift 3.0,
static func callToNumber(number:String) {
let phoneFallback = "telprompt://\(number)"
let fallbackURl = URL(string:phoneFallback)!
let phone = "tel://\(number)"
let url = URL(string:phone)!
let shared = UIApplication.shared
if(shared.canOpenURL(fallbackURl)){
shared.openURL(fallbackURl)
}else if (shared.canOpenURL(url)){
shared.openURL(url)
}else{
print("unable to open url for call")
}
}

Answer 8

The Java RoboVM equivalent:
public void dial(String number)
{
NSURL url = new NSURL("tel://" + number);
UIApplication.getSharedApplication().openURL(url);
}

Answer 9

Tried the Swift 3 option above, but it didnt work. I think you need the following if you are to run against iOS 10+ on Swift 3:
Swift 3 (iOS 10+):
let phoneNumber = mymobileNO.titleLabel.text
UIApplication.shared.open(URL(string: phoneNumber)!, options: [:], completionHandler: nil)

Answer 10

let phone = "tel://\("1234567890")";
let url:NSURL = NSURL(string:phone)!;
UIApplication.sharedApplication().openURL(url);

Answer 11

'openURL:' is deprecated: first deprecated in iOS 10.0 - Please use openURL:options:completionHandler: instead
in Objective-c iOS 10+ use :
NSString *phoneNumber = [#"tel://" stringByAppendingString:mymobileNO.titleLabel.text];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber] options:#{} completionHandler:nil];

Answer 12

Swift
if let url = NSURL(string: "tel://\(number)"),
UIApplication.sharedApplication().canOpenURL(url) {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
}

Answer 13

Use openurl.
For making a call in swift 5.1, just use the following code: (I have tested it in Xcode 11)
let phone = "1234567890"
if let callUrl = URL(string: "tel://\(phone)"), UIApplication.shared.canOpenURL(callUrl) {
UIApplication.shared.open(callUrl)
}
Edit: For Xcode 12.4, swift 5.3, just use the following:
UIApplication.shared.open(NSURL(string: "tel://555-123-1234")! as URL)
Make sure that you import UIKit, or it will say that it cannot find UIApplication in scope.
