blocks|key|4600993|text|关于Apple+Dev的最后一篇可用文档来自2010年3月15日，涵盖了iOS+4.0，其中包括以下类：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4600994|4600995|CTCall|unordered-list-item|4600996|CTCallCenter|4600997|CTCarrier|4600998|CTTelephonyNetwork|4600999|4601000|iOS+7更新的唯一可用文档包括Kogus发布的内容，以及一行“如需更新，请查看头文件”。在XCode中打开框架时，iOS+7中提供了以下类：|4601001|4601002|4601003|4601004|4601005|CTSubscriber|offset|length|style|BOLD|4601006|CTSubscriberInfo|4601007|4601008|4601009|根据关于无线电技术的iOS+7说明，看起来最相关的更改发生在CTTelephonyNetwork类中，添加了currentRadioAccessTechnology属性。|CODE|4601010|基于github的链接，看起来实际上有更多的可用资源。但我敢打赌，这些大部分都是私有API。我认为最安全的方法是坚持使用Xcode中提供的公共头文件。为此，在iOS+7中添加的相关位将是(删除了iOS+7之前的代码)：|4601011|/*

The last available documentation on Apple Dev is from March 15, 2010, covers iOS 4.0, and includes the following classes:

<ul>
<li>CTCall</li>
<li>CTCallCenter</li>
<li>CTCarrier</li>
<li>CTTelephonyNetwork</li>
</ul>

The only available documentation for iOS 7 updates include what Kogus posted as well as a single line that says "for updates, look at the header files". When you open up the framework in XCode, the following classes are available in iOS 7:

<ul>
<li>CTCall</li>
<li>CTCallCenter</li>
<li>CTCarrier</li>
<li>CTSubscriber</li>
<li>CTSubscriberInfo</li>
<li>CTTelephonyNetwork</li>
</ul>

Based on the iOS 7 note about radio technology, it looks like the most pertinent change is within the <code>CTTelephonyNetwork</code> class, with the addition of the <code>currentRadioAccessTechnology</code> property.

It looks like there is actually a LOT more available, just based on the github link. But I'm willing to bet that those are mostly private APIs. I think the safest approach would be to stick to public headers available in Xcode. To that end, the pertinent bits added in iOS 7 would be (with pre iOS 7 code removed):

<pre><code>/*
 * CTSubscriberTokenRefreshed
 *
 * Description:
 * The name of the NSNotification sent when the carrier token is available.
 */
CORETELEPHONY_EXTERN NSString * const CTSubscriberTokenRefreshed __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_7_0);

CORETELEPHONY_CLASS_AVAILABLE(7_0)
@interface CTSubscriber : NSObject

/*
 * carrierToken
 *
 * Description:
 * A data blob containing authorization information about the subscriber.
 *
 * May return nil if no token is available.
 */
@property (nonatomic, readonly, retain) NSData* carrierToken __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_7_0);
</code></pre>

And...

<pre><code>/*

#import &lt;Foundation/Foundation.h&gt;

Hope that helps.

Are there any Changes which will allow more in the CoreTelephony Framework in iOS 7?! I found the new Headerfiles here:

<a href="https://github.com/EthanArbuckle/IOS-7-Headers/tree/master/Frameworks/CoreTelephony.framework" rel="nofollow">https://github.com/EthanArbuckle/IOS-7-Headers/tree/master/Frameworks/CoreTelephony.framework</a>

So, does that mean that it is now allowed to use those methods?! Or are they still private?!

iOS 7中的CoreTelephony框架是否有允许更多内容的更改？！我在这里找到了新的Headerfiles：那么，这是否意味着它现在被允许使用这些方法呢？！或者他们仍然是私人的？！
