应用中的电话拨打

下面方法将会弹出一个alertSheet表单并让客户选择是否拨打电话

- (void)showMessage

{

    UIAlertController * alertController = [UIAlertController alertControllerWithTitle:@"联系客服" message:@"\n客服电话：123456" preferredStyle:UIAlertControllerStyleActionSheet];

    UIAlertAction * actionCall = [UIAlertAction actionWithTitle:@"拨 打" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {

#warning 打开下面代码  并修改客服电话

//        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://这里换成客服电话"]];

    }];

    UIAlertAction * actionCancel = [UIAlertAction actionWithTitle:@"返 回" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {

        

    }];

    [alertController addAction:actionCall];

    [alertController addAction:actionCancel];

    [self presentViewController:alertController animated:YES completion:nil];

}
