在 iOS 应用程序中拨打电话

发布于 2024-11-15 02:25:05 字数 399 浏览 3 评论 0原文

我有一些代码尝试在应用程序中拨打电话，但它似乎不起作用：

    UIApplication *myApp = [UIApplication sharedApplication];
    NSString *theCall = [NSString stringWithFormat:@"tel://%@",phone];
    NSLog(@"making call with %@",theCall);
    [myApp openURL:[NSURL URLWithString:theCall]];

有时，变量 phone 类似于 @"(102) 222-第2222章如何使用这样的电话号码拨打电话？我是否需要手动从中提取数字并删除所有多余的标点符号？

原文

I have some code which attempts to make a call within an application, but it doesn't seem to be working:

    UIApplication *myApp = [UIApplication sharedApplication];
    NSString *theCall = [NSString stringWithFormat:@"tel://%@",phone];
    NSLog(@"making call with %@",theCall);
    [myApp openURL:[NSURL URLWithString:theCall]];

Sometimes, the variable phone is something such as @"(102) 222-2222". How can I make a call with a phone number like this? Do I need to manually extract the numbers out of it and get rid of all the extra punctuation?

是的。你需要自己把它们拿出来。或者您可以使用下面的代码片段...

NSString *cleanedString = [[phoneNumber componentsSeparatedByCharactersInSet:[[NSCharacterSet characterSetWithCharactersInString:@"0123456789-+()"] invertedSet]] componentsJoinedByString:@""];
NSURL *telURL = [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", cleanedString]];

注意：您可能会想使用 -stringByTrimmingCharactersInSet:，但是该方法仅删除字符串开头和结尾的字符，而不是如果它们出现在中间。

Yup. You need to take those out yourself. Or you can use the snippet below...

NSString *cleanedString = [[phoneNumber componentsSeparatedByCharactersInSet:[[NSCharacterSet characterSetWithCharactersInString:@"0123456789-+()"] invertedSet]] componentsJoinedByString:@""];
NSURL *telURL = [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", cleanedString]];

Note: you may be tempted to use -stringByTrimmingCharactersInSet:, but that one only removes characters at the start and the end of the string, not if they appear in the middle.

要返回原始应用程序，您可以使用 telprompt:// 而不是 tel:// - 告诉提示将首先提示用户，但当通话完成后，它将返回您的应用程序：

NSString *phoneNumber = [@"telprompt://" stringByAppendingString:mymobileNO.titleLabel.text];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];

只是对上述答案的更新。

To go back to original app you can use telprompt:// instead of tel:// - The tell prompt will prompt the user first, but when the call is finished it will go back to your app:

NSString *phoneNumber = [@"telprompt://" stringByAppendingString:mymobileNO.titleLabel.text];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];

just an update on above answer.

这是一个简单的方法，可用于拨打电话并在通话结束后返回到应用程序。

将以下内容添加到您的 .m 文件中

- (void) dialNumber:(NSString*) number{
number = [@"telprompt://" stringByAppendingString:number];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:number]];
}

然后在您想要进行调用的任意位置添加以下代码：

[self dialNumber:@"5031234567"];

Here's a simple method that can be used to make a call and return to the app after the call is finished.

Add the following to your .m file

- (void) dialNumber:(NSString*) number{
number = [@"telprompt://" stringByAppendingString:number];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:number]];
}

Then add the following code wherever you want to make the call from:
