从设置包中获取（默认）值

我有一个IOS5项目。

我已向我的项目添加了一个设置包，并向其中添加了一些设置。

我设置“host_ip”的属性：

<dict>
        <key>AutocapitalizationType</key>
        <string>None</string>
        <key>AutocorrectionType</key>
        <string>No</string>
        <key>DefaultValue</key>
        <string>http://localhost</string>
        <key>IsSecure</key>
        <false/>
        <key>Key</key>
        <string>host_ip</string>
        <key>KeyboardType</key>
        <string>URL</string>
        <key>Title</key>
        <string>Host</string>
        <key>Type</key>
        <string>PSTextFieldSpecifier</string>
    </dict>

我尝试读取这样的值：

NSUserDefaults *userDefaults =[NSUserDefaults standardUserDefaults];
NSString *host = [userDefaults stringForKey:@"host_ip"];
NSLog(@"%@",host);

它不返回我在host_ip中设置的默认值，它返回nil。

我怎样才能得到我的默认值？

更新

用户编辑设置后，我可以通过上面的代码检索它。我的问题是获取设置值（如果用户尚未编辑它）。我认为在这种情况下它应该返回我在 plist 中设置的默认值。

I have an IOS5 project.

I have added a settings bundle to my project and added some settings to it.

I set properties of 'host_ip':

<dict>
        <key>AutocapitalizationType</key>
        <string>None</string>
        <key>AutocorrectionType</key>
        <string>No</string>
        <key>DefaultValue</key>
        <string>http://localhost</string>
        <key>IsSecure</key>
        <false/>
        <key>Key</key>
        <string>host_ip</string>
        <key>KeyboardType</key>
        <string>URL</string>
        <key>Title</key>
        <string>Host</string>
        <key>Type</key>
        <string>PSTextFieldSpecifier</string>
    </dict>

I try to read value like this:

NSUserDefaults *userDefaults =[NSUserDefaults standardUserDefaults];
NSString *host = [userDefaults stringForKey:@"host_ip"];
NSLog(@"%@",host);

It does not return the default value I set in host_ip, it returns nil.

How can I get my default value?

UPDATE

After a user edits a setting, I can retrieve it by the code above. My problem is getting the setting value, if it was not edited by the user yet. As I think in that case it should return the default I set in plist.
