cant open file in app from email
<p>i have managed to get my app to email a copy of its database to my self, but now when i try and re open it, it says "open in my app" but does nothing. This is what i have in my info.plist</p>

<pre><code>&lt;key&gt;UTExportedTypeDeclarations&lt;/key&gt;
&lt;array&gt;
    &lt;dict&gt;
        &lt;key&gt;UTTypeIdentifier&lt;/key&gt;
        &lt;string&gt;com.darcapps.myapp.lb&lt;/string&gt;
        &lt;key&gt;UTTypeDescription&lt;/key&gt;
        &lt;string&gt;myapp backup&lt;/string&gt;
        &lt;key&gt;UTTypeTagSpecification&lt;/key&gt;
        &lt;dict&gt;
            &lt;key&gt;public.filename-extension&lt;/key&gt;
            &lt;string&gt;lb&lt;/string&gt;
            &lt;key&gt;public.mime-type&lt;/key&gt;
            &lt;string&gt;application/myapp&lt;/string&gt;
        &lt;/dict&gt;
        &lt;key&gt;UTTypeConformsTo&lt;/key&gt;
        &lt;array&gt;
            &lt;string&gt;public.data&lt;/string&gt;
        &lt;/array&gt;
    &lt;/dict&gt;
&lt;/array&gt;
&lt;key&gt;CFBundleDocumentTypes&lt;/key&gt;
&lt;array&gt;
    &lt;dict&gt;
        &lt;key&gt;CFBundleTypeName&lt;/key&gt;
        &lt;string&gt;myapp backup&lt;/string&gt;
        &lt;key&gt;LSHandlerRank&lt;/key&gt;
        &lt;string&gt;Owner&lt;/string&gt;
        &lt;key&gt;CFBundleTypeRole&lt;/key&gt;
        &lt;string&gt;Editor&lt;/string&gt;
        &lt;key&gt;LSItemContentTypes&lt;/key&gt;
        &lt;array&gt;
            &lt;string&gt;com.darcapps.myapp.lb&lt;/string&gt;
        &lt;/array&gt;
    &lt;/dict&gt;
&lt;/array&gt;
</code></pre>

<p>The other thing i wasnt sure about was <code>&lt;string&gt;com.mycompany.myapp.extName&lt;/string&gt;</code>
Do i have to set these anywhere? eg do i have to set a setting anywhere to tell it what my app is called and what my company is?
thanks</p>
