Support keybinding. 57 157 yongsun In this approach the system takes each keydown and trys to map the keydown 58 157 yongsun to an action method that the input method has implemented. If an action 59 157 yongsun is found the system calls didCommandBySelector:client:. If no action 60 157 yongsun method is found inputText:client: is called. An input method choosing 61 157 yongsun this approach should implement 62 157 yongsun 63 157 yongsun -(BOOL)inputText:(NSString*)string client:(id)sender; 64 157 yongsun -(BOOL)didCommandBySelector:(SEL)aSelector client:(id)sender; 65 157 yongsun 66 157 yongsun 2. Receive all key events without the keybinding, but do "unpack" the relevant text data. 67 157 yongsun Key events are broken down into the Unicodes, the key code that generated 68 157 yongsun them, and modifier flags. This data is then sent to the input method's 69 157 yongsun inputText:key:modifiers:client: method. For this approach implement: 70 157 yongsun 71 157 yongsun -(BOOL)inputText:(NSString*)string key:(NSInteger)keyCode modifiers:(NSUInteger)flags client:(id)sender; 72 157 yongsun 73 157 yongsun 3.
