iOS 开发中实现打电话功能实用代码

一、写一个UIAleitView

	UIAlertView *alert = [[UIAlertView alloc]initWithTitle:nil message:_tellPhone delegate:self cancelButtonTitle:@"拨号" otherButtonTitles:@"取消", nil];

        [alert show];

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    if (buttonIndex != 1) {

        [self openPhoneCallViewWithphoneNumber:_tellPhone];
    }
}

#pragma mark------拨打电话方法

- (void)openPhoneCallViewWithphoneNumber:(NSString *)phoneNum
{
    if (phoneCallWebView == nil) {

        phoneCallWebView = [[UIWebView alloc] initWithFrame:CGRectZero];

    }
    NSString *newPhoneString = [ShowTeacher_ViewController dealWithPhoneNumber:phoneNum];

    if ([ShowTeacher_ViewController isMobileNumber:newPhoneString]) {

        NSURL* dialUrl = [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", newPhoneString]];

        if ([[UIApplication sharedApplication] canOpenURL:dialUrl])
        {
            if (phoneCallWebView) {

                [phoneCallWebView loadRequest:[NSURLRequest requestWithURL:dialUrl]];
            }
            else{

                [[UIApplication sharedApplication] openURL:dialUrl];
            }
        }
        else
        {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"温馨提示" message:@"设备不支持" delegate:nil cancelButtonTitle:@"确定 " otherButtonTitles:nil, nil];

            [alert show];

            alert = nil;

        }
    } else {

        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"温馨提示" message:@"您选择的号码不合法" delegate:nil cancelButtonTitle:@"确定 " otherButtonTitles:nil, nil];

        [alert show];

        alert = nil;
    }
}

#pragma mark ------处理电话号码

{
    NSString *newPhone = [phone stringByReplacingOccurrencesOfString:@"-" withString:@""];

    return newPhone;
