    //拨打电话的三种方式:

    //拨打电话  1.这种方法，打完电话后还会回到原来的程序，也会弹出提示，推荐这种

    NSMutableString *str = [[NSMutableString alloc] initWithFormat:@"tel:%@",@"13067985873"];

    UIWebView *webView = [[UIWebView alloc] init];

    [webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:str]]];

    [self.view addSubview:webView];

    

//    //2.这种方法，拨打完电话回不到原来的应用，会停留在通讯录里，而且是直接拨打，不弹出提示

//    NSMutableString *str1 = [[NSMutableString alloc] initWithFormat:@"tel:%@",@"13067985873"];

//    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:str1]];

//

//    //3.这种方法也会回去到原来的程序里（注意这里的telprompt），也会弹出提示

    NSMutableString *str2 = [[NSMutableString alloc] initWithFormat:@"telprompt://%@",@"13067985873"];

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:str2]];
