Making a Button Call a Phone Number in iOS
提问by Sam
I want to create a button that, when pressed, will call a phone number on the iPhone. I don't know if this is possible, but if it is I'd love for someone to help me with this.
I dont have any code for it, so someone would need to help me from start to finish.
我想创建一个按钮，当按下该按钮时，将拨打 iPhone 上的电话号码。我不知道这是否可行，但如果可行，我希望有人能帮助我解决这个问题。
我没有任何代码，所以有人需要从头到尾帮助我。

Try this out in your button action
在您的按钮操作中试试这个
-(IBAction)callPhone:(id)sender {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://1115550123"]];
}
Then in Interface Builder you should connect the TouchUpInsideevent to the previously declared action (callPhone:) and you are done.
然后在 Interface Builder 中，您应该将TouchUpInside事件连接到先前声明的操作 ( callPhone:) 并完成。

You can also go back to your original app when finish the call just by using this one instead:
您还可以在结束通话时返回到您的原始应用，只需使用此应用即可：
-(IBAction)callPhone:(id)sender {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"telprompt://2135554321"]];
}
Enjoy!
享受！
