In one embodiment, a method includes receiving a touch input within a particular region of a display area of the computing device. The display area presents a user interface (UI) including a number of views and an outside view. Each of the views corresponds to one or more regions of the display area. One or more of the views has a gesture recognizer configured to process a touch input detected within the regions of the display area associated with each of the views. The outside view has a gesture recognizer configured to process the touch input detected within the display area. The views are organized in a hierarchy. The method also includes determining whether a particular one of the views from among the views is set as a modal view. |
