9. The method according to claim 6, further comprising:

stopping playing the image files according to the first tilt angle when a lock operation is detected.

10. The method according to claim 6, further comprising:

setting the image file being played as a desktop image of the electronic device when a lock operation is detected.

11. The method according to claim 6, further comprising:

setting the image file being played as a desktop image of the electronic device when a lock operation is detected and the electronic device is rotated by a second tilt angle.

12. The method according to claim 1, wherein the method detects the first tilt angle when the electronic device displays a part of a plurality of sets of data;

and the operation comprises changing the displayed part of the plurality of sets of data according to the first tilt angle.

13. The method according to claim 12, wherein the plurality of sets of data form an image file or a webpage, and the first tilt angle is associated with a position of the part in the image file or the webpage.

14. The method according to claim 12, wherein the plurality of sets of data are a plurality of desktops, and the part is one of the plurality of desktops.

15. The method according to claim 1, wherein the method detects the first tilt angle when the electronic device plays a video file;

and the operation comprises adjusting a playback speed of the video file according to the first tilt angle.

16. The method according to claim 15, further comprising:

detecting a second tilt angle between the electronic device and the reference plane;

stopping playing the video file according to the playback speed; and

playing the video file in reverse according to a reverse playback speed corresponding to the second tilt angle;

wherein, the first tilt angle and the second tilt angle are in different quadrants.

17. The method according to claim 1, further comprising:

detecting at least two tilt angles between the electronic device and the reference plane within a predetermined period; and

when the tilt angles satisfy a predetermined combination, controlling the electronic device to perform a designated operation behavior.

18. The method according to claim 17, further comprising:

controlling the electronic device to operate in either a locked state or an unlocked state;

when the tilt angles satisfy the predetermined combination, controlling the electronic device to operate in one other of either the locked state or the unlocked state.

19. The method according to claim 1, further comprising:

detecting the first tilt angle when a trigger operation is detected; and

when the trigger operation is released, performing the operation according to the first tilt angle at time of releasing the trigger operation.

20. An electronic device, comprising:

a screen;

a gravity sensor, configured to detect a first tilt angle between the electronic device and a reference plane; and

a control unit, configured to control the electronic device to perform an operation according to the first tilt angle;
