Electronic device and method of controlling the same

A method for controlling an electronic device with a touch-sensitive screen, comprising:

• while the electronic device is in a user-interface lock state, displaying a first object and a second object corresponding to an unlock operation on the touch-sensitive screen, wherein the first object links to an edge of a display of the touch-sensitive screen, and the second object links to the first object, rather than linking to any edge of the display;
• detecting a contact with the touch-sensitive screen, while the electronic device is in the user-interface lock state;
• in response to the detected contact on the touch-sensitive screen, determining whether a continuous moving path corresponding to the contact has passed through the first object, and determining whether a moving acceleration of the contact has exceeded a preset value;
• when the continuous moving path corresponding to the contact has passed through the first object, and the moving acceleration of the contact has exceeded the preset value, separating the displayed first object into a first stationary part and a first disassociated part, wherein the first stationary part is linked to the edge of the display, and the first disassociated part is linked to the second object, and the first disassociated part is displayed as being severed from the first stationary part and moving away, along with the second object, from the first stationary part according to pre-determined physical principles;
• and
• controlling the electronic device to switch from the user-interface lock state into a work state.
