How to open system's iPhone Dial pad in iOS app

Question

问题是：我不想立即拨打电话，我需要在用户点击“通话”按钮时，应用跳到电话应用中的拨号盘，然后输入用户的电话号码，然后用户可以按“通话”按钮进行通话。这个电话。

[[UIApplication sharedApplication] openURL:@"tel://"]

Answer 1

This is not possible, however why don't you like the 'tel://' method since it keeps the user in your app once the call terminates? I haven't seen a single app that redirects to the call screen to dial a number since the call button is more simpler.
