你的问题分为两部分：
1.在录制UILabel时执行任何类型的操作
1.执行电话呼叫操作（第一部分中使用的操作）
首先，要在标签粘贴时执行操作，您必须向此标签添加一个点击手势识别器：

phoneNumberLabel.userInteractionEnabled = YES;
UITapGestureRecognizer *tapGesture = 
   [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(phoneNumberLabelTap)];
[phoneNumberLabel addGestureRecognizer:tapGesture];

字符串
然后你必须实现你的phoneNumberLabelTap方法：

-(void)phoneNumberLabelTap
{
    NSURL *phoneUrl = [NSURL URLWithString:[NSString stringWithFormat:@"telprompt:%@",phoneNumberLabel.text]];

    if ([[UIApplication sharedApplication] canOpenURL:phoneUrl]) {
        [[UIApplication sharedApplication] openURL:phoneUrl];
    } else {
        UIAlertView * calert = [[UIAlertView alloc]initWithTitle:@"Alert" message:@"Call facility is not available!!!" delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil, nil];
        [calert show];
    }
}

在Swift 3.0中：

mobileLabel.isUserInteractionEnabled = true;
let tap = UITapGestureRecognizer(target: self, action:#selector(self.phoneNumberLabelTap))
mobileLabel.addGestureRecognizer(tap)

func phoneNumberLabelTap() {        
    let phoneUrl = URL(string: "telprompt:\(mobileLabel.text ?? "")")!

    if(UIApplication.shared.canOpenURL(phoneUrl)) {
        UIApplication.shared.openURL(phoneUrl)
    } else {
        Constants.ShowAlertView(title: "Alert", message: "Cannot place call", viewController: self, isFailed: false)
    }
}

SWIFT 3+
标签添加点击手势识别器

let tap = UITapGestureRecognizer(target: self, action:#selector(self.phoneNumberLabelTap))
    supportCallLabel.isUserInteractionEnabled = true
    supportCallLabel.addGestureRecognizer(tap)
}

phoneNumberLabelTap方法

• 这里，常量.supportCall是你的号码 *

@objc func phoneNumberLabelTap() {
    if let url = URL(string: "tel://\(Constants.supportCall)"), UIApplication.shared.canOpenURL(url) {
        if #available(iOS 10, *) {
            UIApplication.shared.open(url)
        } else {
            UIApplication.shared.openURL(url)
        }
    }
}
