A method includes detecting first movement of a first contact on an on-screen ruler in a first direction around a pivot location; in response to the first movement: rotating the ruler by an angular amount according to the first movement; and when the ruler has entered a snap zone associated with a snap angle upon rotation by the first angular amount, rotating the ruler by a first adjusted amount to bring the ruler into alignment with the first snap angle; detecting second movement of the first contact in a second direction and the second movement satisfies unsnapping criteria; and in responseto the second movement, rotating the ruler by a second adjusted amount to bring the ruler into alignment with the first contact. 本发明公开了种方法，该方法包括：检测屏幕上尺子上的第接触围绕枢转位置在第方向上的第移动；响应该第移动：根据该第移动来将尺子旋转角度量；并且在旋转第角度量的情况下尺子已进入与对齐角相关联的对齐区域时，将尺子旋转第调整量，以使尺子与第对齐角对准；检测第接触在第二方向上的第二移动并且检测到第二移动满足解除对齐标准；以及响应于该第二移动，将尺子旋转第二调整量，以使尺子与第接触对准。
