Static Methods
ToObject(this NSObject)
Takes a base NSObject and, depending on it's actual type, will convert the iOS object to a .NET equivalent.
public static object ToObject(this NSObject obj)
Example
This example shows how the ToObject method can be used to convert a stored value from the iOS NSUserDefaults to the .NET equivalent object.
public bool TryGetValue(string key, out object value)
{
    NSObject nsObj = null;
    if (!this.ContainsKey(key))
    {
        value = null;
    }
    else
    {
        lock (this.obj)
        {
            // Retrieve a value key from the NSUserDefaults instance.
            nsObj = this.standardUserDefaults.ValueForKey(new NSString(key));
        }
​
        // Converts the NSObject to the relevant .NET equivalent.
        value = nsObj.ToObject();
    }
​
    return nsObj != null;
}
