Answer 1

在你认为我之前，我不是Popeye提供了另一个答案。

直到我的回答。有几种方法可以做到这一点

// Pick one of the two ways from below, one will return you to the app afterwards the other will not.
// This version of of creating the number will open the dialer but will not return you to the app afterwards.
NSURL *phoneNumber = [NSURL urlWithString:[NSString stringWithFormat:@"tel://%@", yourNumberString]];

// Whilst this version will return you to your app once the phone call is over.
NSURL *phoneNumber = [NSURL urlWithString:[NSString stringWithFormat:@"telprompt://%@", yourNumberString]];

// Now that we have our `phoneNumber` as a URL. We need to check that the device we are using can open the URL.
// Whilst iPads, iPhone, iPod touchs can all open URLs in safari mobile they can't all 
// open URLs that are numbers this is why we have `tel://` or `telprompt://`
if([[UIApplication sharedApplication] canOpenURL:phoneNumber]) {
    // So if we can open it we can now actually open it with
    [[UIApplication sharedApplication] openURL:phoneNumber];
}

希望如果您有任何疑问，请帮助我们。

Answer 2

iPhone SDK不允许您直接访问app中的拨号号码。因此，您无法执行此操作，但有一种方法可以实现此目的。

- ＆GT;使用keyBoardType UIKeyboardTypePhonePad创建一个TextField（yourPhoneNumber）。

- ＆GT; [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"telprompt://%@",yourPhoneNumber.text]]];

希望这会帮助你。
