This class provides an interface to Cocoa's
spellchecking
service. A shared instance of NSSpellChecker is
returned using the class method
sharedSpellChecker. To check the spelling of a
length of text, invoke the method
checkSpellingOfString:startingAt:, which takes the
string to check and the offset in the string where the spellcheck
should commence. This method will return an
NSRange indicating the location of the first
misspelled word. Clients then update the contents of the
spellchecking panel to notify the user of the discovery of the
misspelled word using the method
updateSpellingPanelWithMisspelledWord:; passing an
empty string here will cause the spellchecking process to terminate.
Support for spellchecking services is built into the Cocoa text
handling classes. If you wish to implement support for spellchecking
into a class of your own, then you must implement the methods
declared in the NSChangeSpelling and
NSIgnoreMisspelledWords protocols; see the
protocol descriptions in Chapter 16 for more
information.
