如何在iOS上拨打此号码* 199 * 123456789＃？

我使用了以下代码，但它不起作用。

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel:*199*123456789#"]];

Answer 1

引用URL scheme docs

防止用户恶意重定向电话或更改电话应用程序支持的电话或帐户的行为 tel方案中的大多数但不是全部的特殊字符。具体来说，如果URL包含*或＃字符，则为Phone 应用程序不会尝试拨打相应的电话号码。

从我所看到的情况看，它看起来像你可以使用的唯一方案是：

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://1234567890p111"]];

拨打分机。

将*替换为%2A，将#替换为%23：

NSURL *tel = [NSURL URLWithString:@"tel:%2A199%2A123456789%23"];
[[UIApplication sharedApplication] openURL:tel];

Answer 3

根据我对现已结束的问题的回答重新发布和修改＆＃34; iOS - I want to call phone number "#51234" in Xcode useing telprompt＆＃34;：

至少从iOS 11开始，一个可以拨打带有＃标签（＃）或星号（*）的数字。

首先使用这些字符进行调用编码电话号码，然后添加tel:前缀，最后将结果字符串转换为网址。

Swift 4，iOS 11

// 1) set up the dial sequence as a String
let dialSequence = "*199*123456789#"

// 2) "percent encode" the dial sequence with the "URL Host Allowed" character set
guard let encodedDialSequence =
    dialSequence.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed) else {
    print("Unable to encode the dial sequence.")
    return
}

// 3) add the `tel:` url scheme to the front of the encoded string
// NOTE: the '//' part is optional: either 'tel:' or 'tel://' will work.
let dialURLString = "tel:\(encodedDialSequence)"

// 4) set up the URL with the scheme+encoded number string
guard let dialURL = URL(string: dialURLString) else {
    print("Couldn't convert the dial string into an URL.")
    return
}

// 5) dial the URL
UIApplication.shared.open(dialURL, options: [:]) { success in
    if success { print("SUCCESSFULLY OPENED DIAL URL") }
    else { print("COULDN'T OPEN DIAL URL") }
}

Objective-C，iOS 11

// 1) set up the dial sequence as a String
NSString *dialSequence = @"*199*123456789#";

// 2) "percent encode" the dial sequence with the "URL Host Allowed" character set
NSCharacterSet *urlHostAllowed = [NSCharacterSet URLHostAllowedCharacterSet];
NSString *encodedDialSequence = [dialSequence stringByAddingPercentEncodingWithAllowedCharacters:urlHostAllowed];

// 3) add the 'tel:' url scheme to the front of the encoded string
// NOTE: the '//' part is optional: either 'tel:' or 'tel://' will work.
NSString *dialURLString = [NSString stringWithFormat:@"tel:%@", encodedDialSequence];

// 4) set up the URL with the scheme+encoded number string
NSURL *dialURL = [NSURL URLWithString:dialURLString];

// 5) set up an empty dictionary for the options parameter
NSDictionary *optionsDict = [[NSDictionary alloc] init];

// 6) dial the URL
[[UIApplication sharedApplication] openURL:dialURL
                                   options:optionsDict
                         completionHandler:^(BOOL success) {
                             if (success) { NSLog(@"SUCCESSFULLY OPENED DIAL URL"); }
                             else { NSLog(@"COULDN'T OPEN DIAL URL"); }
                         }];
