your code is correct. did you check in real device. this function will not work in simulator.
你的代码是正确的。你在真机上签到了吗？此功能在模拟器中不起作用。
try this also,
也试试这个，
NSString *phNo = @"+919876543210";
NSURL *phoneUrl = [NSURL URLWithString:[NSString stringWithFormat:@"telprompt:%@",phNo]];
if ([[UIApplication sharedApplication] canOpenURL:phoneUrl]) {
[[UIApplication sharedApplication] openURL:phoneUrl];
} else
{
calert = [[UIAlertView alloc]initWithTitle:@"Alert" message:@"Call facility is not available!!!" delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil, nil];
[calert show];
}
** Swift 3 version**
** Swift 3 版本**
if let url = URL(string: "telprompt:\(phoneNumber)") {
if UIApplication.shared.canOpenURL(url) {
UIApplication.shared.openURL(url)
}
}

Telephony does not work on simulators/iPod/iPad, you will require to run the app on an iPhone with active sim card.
电话在模拟器/iPod/iPad 上不起作用，您需要在带有活动 SIM 卡的 iPhone 上运行该应用程序。
Also the URL scheme to invoke the telephony application is tel:<phone_number>. Refer Apple docs.
调用电话应用程序的 URL 方案也是tel:<phone_number>. 请参阅Apple 文档。
Ideally, you should check if the device is having the telephony module and then perform the openURL:call. Use this code to perform the check,
理想情况下，您应该检查设备是否具有电话模块，然后执行openURL:呼叫。使用此代码执行检查，
if([[UIApplication sharedApplication] canOpenURL:callUrl]) {
[[UIApplication sharedApplication] openURL:callUrl];
}
else {
//Show error message to user, etc.
}

Use following method to make call:
使用以下方法拨打电话：
NSString *phoneNumber = [@"tel://" stringByAppendingString:number];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];
回答by kshitij godara
NSString *phoneNumber = [@"tel://" stringByAppendingString:@"9414481799"];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];
This will only run on device.
这只会在设备上运行。
