EVENT RECOGNITION

While displaying one or more views of a first software application, an electronic device detects a sequence of touch inputs. The electronic device, in accordance with a determination that at least one gesture recognizer in the first software application recognizes a first portion of the sequence, delivers the sequence to the first software application without delivering the sequence to a second software application, and in accordance with a determination that a first gesture recognizer in the first software application recognizes the sequence, processes the sequence with the first gesture recognizer. The electronic device, in accordance with a determination that no gesture recognizer in the first software application recognizes the first portion, delivers the sequence to the second software application, and in accordance with a determination that a second gesture recognizer in the second software application recognizes the sequence, processes the sequence with the second gesture recognizer.
