Provided are a method and apparatus for sharing information between user spaces, and a terminal. The method comprises: the apparatus for sharing information between user spaces displaying the content of an associated user data storage space in a target user data storage space when detecting that an operation performed, by a user, on the target user data storage space satisfies a cross-sectional content display condition, with the associated user data storage space being the content of other user data storage spaces associated with the target user data storage space; and continuously detecting whether the operation of the user always satisfies the cross-sectional content display condition, and when it is detected that the condition is not satisfied, clearing the content of the other user data storage spaces associated with the target user data storage space. The present invention effectively solves the problems in the prior art that the switching process is cumbersome and that the user experience is poor when
