CHAPTER 16

Find

16-8 Using the Find Service

ROM_CompatibleFinder proto, the string to display for each found item is

contained in the

title slot of each of the items in the items array in your finder.

When the user taps scroll buttons to scroll through this list of found items, the

system keeps track of the user’s place in the array of found items. Figure 16-8

depicts the strings from both the

title slot and the FindSoupExcerpt method

as they are used in a typical Find overview.

Figure 16-8 Strings used in a Find overview

When the user taps an item in the overview, the system sends a ShowFoundItem

message to the view speciﬁed by the

owner slot in your ﬁnder frame (which you

appended to the system’s

results array). In the template of the speciﬁed owner

view, you deﬁne a

ShowFoundItem method that must locate the found item in

your application’s data and perform any actions necessary to display it, including

scrolling or highlighting the item as appropriate. Although the interface to the

ShowFoundItem method varies according to the finder proto your finder is based

on, you can often use the same method to display the results of both text and date

searches. If you are using a ﬁnder based on

ROM_CompatibleFinder, you must

override its ShowFakeEntry method to call your ShowFoundItem method.
