在iOS中拨打号码真的需要确认？ [英] Dial number in iOS really need confirmation?

问题描述

我使用以下代码拨打号码并使用我的设备进行测试。

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

不需要确认，完成编程。如果点击了号码，您将只能在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，我认为客户看到一个对话框更方便他们不会不小心打电话给别人。

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.

要模仿什么safari，你可以做这样的事情：

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;
    }
}
