iOS中的拨号真的需要确认吗?

问题描述

我正在使用以下代码拨打号码并使用我的设备进行测试.似乎不需要确认，对吗?

I am using the following code to dial number and testing with my device. It seems no confirmation is needed, correct?

NSURL *url = [NSURL URLWithString:@"tel://12345678"];
[[UIApplication sharedApplication] openURL:url];

推荐答案

确认不是必需的，并且在以编程方式完成时不会显示.如果单击数字，您只会在 Safari 中看到 alertView.

Confirmation isn't required and isn't shown when done programmatically. You will only see the alertView in Safari if a number is clicked.

但是，根据我自己的经验，我相信客户看到对话框会更方便，这样他们就不会不小心给某人打电话.人们只是想都没想就点击应用中的东西，在这种情况下可能会很糟糕.

However, in my own experience, I believe it's more convenient for the customer to see a dialog box so they don't accidentally call someone. People just tap things in apps without even thinking and that could be bad in this case.

要模仿 safari 的功能，您可以执行以下操作:

To mimic what safari does you can do something like this:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:@"Call 12345678?" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Call", nil];
[alert show];
alert.tag = 1;
[alert release];

和

-(void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
    switch (alertView.tag) {
        case 1:
            if (buttonIndex == 1) {
                NSURL *url = [NSURL URLWithString:@"tel://12345678"];
                [[UIApplication sharedApplication] openURL:url];
            }
            break;
        default:
            break;
    }
}
