5. The method of claim 1 , including: during a second phase of detecting the sequence of touch inputs, subsequent to the first phase: delivering the second portion of one or more touch inputs to the first software application without delivering the second portion of one or more touch inputs to the second software application; identifying from the one or more matching gesture recognizers a second matching gesture recognizer that recognizes the sequence of touch inputs; and processing the sequence of touch inputs with a gesture handler corresponding to the respective matching gesture recognizer.
