虽然方法被调用，但它无法正常工作：

I'm trying to call a phone number from ios app using: It's not working, although the method gets called:

-(IBAction)callPhone:(id)sender {

        NSString *phoneCallNum = [NSString stringWithFormat:@"tel://%@",listingPhoneNumber ];

        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneCallNum]];

推荐答案

你的代码是正确的。你检查了真实的设备吗？此功能在模拟器中不起作用。

your code is correct. did you check in real device. this function will not work in simulator.

试试这个，

NSString *phNo = @"[phone]";
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版本**

** Swift 3 version**

if let url = URL(string: "telprompt:\(phoneNumber)") {
  if UIApplication.shared.canOpenURL(url) {
    UIApplication.shared.openURL(url)
  }
}
