Devices, Methods, and Graphical User Interfaces for Manipulating User Interface Objects with Visual and/or Haptic Feedback

摘要

In accordance with some embodiments, a method is performed at an electronic device. The device displays a first user interface including a background with a first appearance and foreground objects. While displaying the first user interface, the device detects a first input while a first focus selector is at a location in the first user interface that corresponds to the background of the first user interface. In response, if the contact has a characteristic intensity above a first intensity threshold, the device dynamically changes the background without changing the foreground objects, wherein the dynamic change in the background is based on the characteristic intensity of the contact. While dynamically changing the background, detecting termination of the first input; and, in response, the device reverts the background back to the first appearance of the background.
