Patent US 10,884,591

An electronic device having a touch-sensitive surface displays a plurality of user interface objects, detects selection of a first user interface object, detects a gesture that includes movement of a contact across the touch-sensitive surface, and in response, moves the first user interface object on the display within a predefined distance of a second user interface object. If the gesture meets predefined intensity criteria, the device performs a first device-generated alignment operation, including moving the second user interface object into alignment with the first user interface object, and if the gesture does not meet the predefined intensity criteria, the device performs a second device-generated alignment operation, includes moving the first user interface object into alignment with the second user interface object by adjusting a position of the first user interface object with respect to a current position of the second user interface object on the display.
