SerializedObject.GetIterator

説明

1つ目のシリアライズ化されたプロパティーを取得します

You can use this to go over all properties of the target object. Typically, when the desired field name is known, it is better to use FindProperty to retrieve the associated SerializedProperty more quickly. However this method can be useful for more general code that needs to scan different types of objects, e.g. when the names of desired properties is not known in advance.
