information at that time. For example, if a user queued several fax items from

home but didn’t send them until she got to work, the area code information for

telephone numbers might need to be changed.

Using protoAddressPicker 22

This proto consists of a labeled ﬁeld that you can use in the routing slip to allow

the user to choose the recipient(s) of the item being sent. The ﬁrst time the user

taps on the address picker, it opens a view that displays a list of names from the

Names ﬁle, from which the user can choose one or more recipients (Figure 22-5).

Figure 22-5 protoPeoplePicker view

This view uses the protoPeoplePicker to provide the name picking facility. The

address picker is customizable so that you can substitute a name picking service

other than

protoPeoplePicker by setting the _picker slot. For example, an

e-mail transport might use this facility to provide an alternate directory service.

When the user picks a name, the information is saved, and the next time the address

picker opens, it displays a small picker with the saved name and the choice “Other

Names.” The user can choose “Other Names” to reopen the

protoPeoplePicker

view and select from the comprehensive list of names. Each time a new name is

selected, it is saved and added to the initial address picker list, giving the user a

convenient way to select from recently used addresses, as shown in Figure 22-6.

The address picker remembers the last eight names selected.
