iOS 开发中实现打电话功能实用代码

一、写一个UIAleitView

<span style="color:#cc33cc;"><span style="white-space:pre"></span>UIAlertView *alert = [[UIAlertView alloc]initWithTitle:nil message:_tellPhone delegate:self cancelButtonTitle:@"拨号" otherButtonTitles:@"取消", nil];                            [alert show];</span>

二、点击alertView触发

<span style="font-size:14px;color:#cc33cc;">- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{    if (buttonIndex != 1) {                [self openPhoneCallViewWithphoneNumber:_tellPhone];    }}</span>

三、实现代码，其实这个代码我也没有具体的研究，大家复制过去用就可以实现这个功能了

#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 *)dealWithPhoneNumber:(NSString *)phone{    NSString *newPhone = [phone stringByReplacingOccurrencesOfString:@"-" withString:@""];        return newPhone;}#pragma mark------判断是否是电话号码+ (BOOL)isMobileNumber:(NSString *)mobileNum{    /**     * 手机号码     * 移动：134[0-8],135,136,137,138,139,150,151,157,158,159,182,187,188     * 联通：130,131,132,152,155,156,185,186     * 电信：133,1349,153,180,189     */    NSString * MOBILE = @"^1(3[0-9]|5[0-35-9]|8[0235-9])\\d{8}$";    /**     * 中国移动：China Mobile     * 134[0-8],135,136,137,138,139,150,151,157,158,159,182,187,188     */    NSString * CM = @"^1(34[0-8]|(3[5-9]|5[017-9]|8[278])\\d)\\d{7}$";    /**     * 中国联通：China Unicom     * 130,131,132,152,155,156,185,186     */    NSString * CU = @"^1(3[0-2]|5[256]|8[56])\\d{8}$";    /**     * 中国电信：China Telecom     * 133,1349,153,180,189     */    NSString * CT = @"^1((33|53|8[09])[0-9]|349)\\d{7}$";    /**     * 大陆地区固话及小灵通     * 区号：010,020,021,022,023,024,025,027,028,029     * 号码：七位或八位     */    NSString * PHS = @"^0(10|2[0-5789]|\\d{3})\\d{7,8}$";        NSPredicate *regextestmobile = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", MOBILE];    NSPredicate *regextestcm = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CM];    NSPredicate *regextestcu = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CU];    NSPredicate *regextestct = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CT];    NSPredicate *regextestphs = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", PHS];        if (([regextestmobile evaluateWithObject:mobileNum] == YES)        || ([regextestcm evaluateWithObject:mobileNum] == YES)        || ([regextestct evaluateWithObject:mobileNum] == YES)        || ([regextestcu evaluateWithObject:mobileNum] == YES)        || ([regextestphs evaluateWithObject:mobileNum] == YES))    {        return YES;    }    else    {        return YES; //暂时不做检查    }}
