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;
}

Parameters

obj (NSObject)

The iOS object to convert to a .NET object.

Returns

Returns the converted .NET object value.
