NSDictionary checking for "<null>" value in ios10
<p>I have <code>NSMutableDictionary</code> which stores data comping from database.
some keys inside <code>NSMutableDictionary</code> has null values like the one shown below.</p>

<p>I wanted to check for null values. I am doing as below:</p>

<pre><code>UserMobileNo = "&lt;null&gt;";
UserAccNo = "&lt;null&gt;";
 if(!([dicUserdata valueForKey:@"UserMobileNo"] == [NSNull null]))
        //Saved result
</code></pre>

<p>but above code do not seems to be checking for null values perfectly.
what is the perfect way of checking null values inside dictionary?</p>
