//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]];

}
