    touches passed as the parameter are the touches in your view.

    event.allTouches contains all the touches of the event, even the one that didn’t start in your view.

    Don’t hesitate to read the Event Handling Guide for iOS in Apple’s doc, it is explained with some pictures it will probably help you understand better.

    Especially the difference between the touches in the parameters and event.allTouches is described here 😉
