<p><p>您的代码似乎不错。我找不到错误所以尝试换行:</p>
<pre><code>self.myDictionary = ;
</code></pre>
<p>到</p>
<pre><code>id unknownObject = ;
NSLog(@"%@",);
</code></pre>
<p>看看@控制台。如果输出是字典，也许你也应该尝试强制转换。所以尝试将其更改为:</p>
<pre><code>self.myDictionary = (NSDictionary*);
</code></pre>
<p><strong>编辑</strong></p>
<pre><code>NSDictionary *dictionary = ;
NSLog(@"before: %@",dictionary);
NSData *myData = ;
NSDictionary *myDictionary = (NSDictionary*) ;
NSLog(@"after: %@",myDictionary);
</code></pre>
<p>输出:</p>
<pre><code>2013-11-13 14:32:31.369 DemoM before: {
key1 = object1;
key2 = object2;
key3 = object3;
}
2013-11-13 14:32:31.372 DemoM after: {
key1 = object1;
key2 = object2;
key3 = object3;
}
</code></pre></p>
