Making Phone Calls on the Iphone

Making phone calls on the iPhone

Try this:

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://8005551212"]];

... which will bring up a dialog in which your users will confirm the call.

iOS making a phone call from the app without a confirmation alert

Unfortunately, what you desire to do is not possible, at least in the existing versions of iOS. That dialog will always show.

Per Apple's documentation for openURL:

When a third party application invokes openURL: on a tel://,
facetime://, or facetime-audio:// URL, iOS displays a prompt and
requires user confirmation before dialing.

Making calls on iPhone/iPod/iPad

Every iOS 8 device has the FaceTime App which now provides the power to call anyone your iPhone can call.

It's called continuity

The user has to allow this on his iPhone in Settings.app under "FaceTime" -> "iPhone Cellular Calls"

Making in-app phone calls on iOS

Nope, to use GSM, it is not possible. You will have to direct that to the dialer. I believe you can develop some sort of solution, if you jailbreak, not sure if that is what you want.

Make a phone call programmatically

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)
}

Making a phone call in an iOS application

Yup. You need to take those out yourself. Or you can use the snippet below...

NSString *cleanedString = [[phoneNumber componentsSeparatedByCharactersInSet:[[NSCharacterSet characterSetWithCharactersInString:@"0123456789-+()"] invertedSet]] componentsJoinedByString:@""];
NSURL *telURL = [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", cleanedString]];

Note: you may be tempted to use -stringByTrimmingCharactersInSet:, but that one only removes characters at the start and the end of the string, not if they appear in the middle.

IOS How to make phone call with nondigits

I wanted to do this, too. There's no way. It's explicitly disallowed by Apple for security reasons:

To prevent users from maliciously redirecting phone calls or changing the behavior of a phone or account, the Phone application supports most, but not all, of the special characters in the tel scheme. Specifically, if a URL contains the * or # characters, the Phone application does not attempt to dial the corresponding phone number.
