如何使用"*" IOS中的char? [英] How to call (dialing) with " * " char in IOS?

问题描述

我希望用*字符致电.例如:* 711313.

I hope to call with * character. ex> *711313.

当前，我正在使用以下代码:

Currently, I'm using this code:

NSString *str = [NSString stringWithFormat:@"tel:%@", tmp];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:[str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]];

我测试了两种情况:

1. tmp = @"719929292"; //还行吧.打电话.

1. tmp = @"719929292"; //this is ok. make call.

tmp = @"* 7128282"; //app没有反应.不打电话.

tmp = @"*7128282"; //app no reaction. not to call.

如何用*(星号)呼叫?

How can I call with *(star character)?

推荐答案

可能必须对星形进行编码才能在URL中使用.尝试使用%2A代替*.

The star may have to be encoded for use in a URL. Try %2A instead of *.

由于*是有效的URL字符，尽管具有特殊含义，但stringByAddingPercentEscapesUsingEncoding:不会执行此替换.

This replacement is not done by stringByAddingPercentEscapesUsingEncoding: since * is a valid URL character, albeit with a special meaning.
